55-457: In 2010, Cowon was ranked number one in the PMP category of Japanese Management Association Consultants’ Global Customer Satisfaction Competency Index, and in 2011, it was ranked number one in the same organization’s Global & Great Brand Competency Index. In the west, Cowon is most well known for its iAUDIO range of portable media players, which has resulted in many people incorrectly referring to

110-664: A hard drive ). Operating systems may treat a USB mass-storage device like a hard drive; users may partition it in any format (such as MBR and GPT), and format it with any file system. Because of its relative simplicity, the most common file system on embedded devices such as USB flash drives , cameras, or digital audio players is Microsoft's FAT or FAT32 file system (with optional support for long filenames ). However, USB mass storage devices may be formatted with any other file system, such as NTFS on Windows NT, HFS Plus on macOS , ext2 on Linux , or Unix File System on Solaris or BSD. This choice may limit (or prevent) access to

165-550: A 1.8-inch (46 mm) LCD with 128×160 resolution and 65 000 colors. The U5 had a 24-hour continuous audio playback time. In November 2009, the iAUDIO E2 was released. The iAudio E2 has no screen which means it fully operates four buttons, two on each side, and voice cues. The button location is at the same place on both sides of the device. The volume fluctuates in minuscule increments. The 2GB memory may be filled with songs to play in order or shuffle; it supports AAC, FLAC, MP3, OGG, and WAV files and can play for up to 11 hours on

220-490: A 128x64-pixel display. The U2's built-in lithium-polymer battery lasted 15 hours. The USB 2.0 transfer rate is at 1.86MB per second. The iAUDIO G3 was introduced November 2004. The internal hardware was very similar to that of the iAUDIO U2. Both players used the same Sigmatel chipset. The only difference between the two players was that the G3 was powered by an AA battery, allowing a playing time of up to 50 hours. The iAUDIO G2

275-441: A 2-inch QVGA (320 x 240-pixel) display positioned atop a capacitive touchpad. It includes a 30mW headphone amplifier, video connectivity (through an extra cable), a microphone, and an FM radio (to record voice and broadcasts). The device is 40g in weight and is 95 x 43 x 8.9mm (3.74 x 1.69 x 0.35 inches) in size. It also supports a variety of audio formats (including rarities like FLAC and OGG) and USB mass storage. In November 2009,

330-461: A USB mass-storage device (such as MP3 players with a USB port) will report a damaged (or missing) file system if they are reformatted with a different file system. However, most default-partition devices may be repartitioned (by reducing the first partition and file system) with additional partitions. Such devices will use the first partition for their own operations; after connecting to the host system, all partitions are available. Devices connected by

385-476: A capacity of up to 32 GB, while the hard drive-based models currently have capacities up to 160 GB. The iAUDIO 6 was the first player to use Toshiba 's new 4GB 0.85″ hard disk. Cowon entered the digital audio player market in October 2000 with the introduction of their first MP3 player, the iAUDIO CW100. In March 2001, the iAUDIO CW100s, a revised model, was released. In December 2001, Cowon released

440-453: A device's contents by equipment using a different operating system. OS-dependent storage options include LVM , partition tables and software encryption. In cameras, MP3 players and similar devices which must access a file system independent of an external host, the FAT32 file system is preferred by manufacturers. All such devices halt their file-system ( dismount ) before making it available to

495-532: A firmware upgrade). Advantages of this method of distribution are lower cost, simplified installation and ensuring driver portability. Some advanced hard disk drive commands, such as Tagged Command Queuing and Native Command Queuing (which may increase performance), ATA Secure Erase (which allows all data on the drive to be securely erased) and S.M.A.R.T. (accessing indicators of drive reliability) exist as extensions to low-level drive command sets such as SCSI , ATA and ATAPI . These features may not work when

550-417: A generic driver) for standard USB mass-storage devices; Windows Me and all later Windows versions also include support. Windows Mobile supports accessing most USB mass-storage devices formatted with FAT on devices with USB Host. However, portable devices typically cannot provide enough power for hard-drive disk enclosures (a 2.5-inch (64 mm) hard drive typically requires the maximum 2.5  W in

605-411: A host operating system to prevent file-system corruption or other damage (although it is theoretically possible for both devices to use read-only mode or a cluster file system ). Some devices have a write-protection switch (or option) allowing them to be used in read-only mode. Two main partitioning schemes are used by vendors of pre-formatted devices. One puts the file system (usually FAT32) directly on

660-625: A number of freeware utilities, including JetCast , JetMailMonitor and JetToolBar . All of the above are available for free download from the JetAudio website. Cowon’s ultra-mobile PCs W2 and W2 SSD come with JetToolbar pre-installed. IAUDIO iAUDIO is the brand name for a range of portable media players produced by Korean consumer electronics and software corporation Cowon Systems, Inc. The iAUDIO range consists of players based on both flash memory and hard disk drives . Flash memory-based players are available with

715-969: A portal for computer viruses . Beginning with Windows 7 , Microsoft limited AutoRun to CD and DVD drives, updating previous Windows versions. Neither MS-DOS nor most compatible operating systems included support for USB. Third-party generic drivers, such as Duse, USBASPI and DOSUSB, are available to support USB mass-storage devices. FreeDOS supports USB mass storage as an Advanced SCSI Programming Interface (ASPI) interface. Apple 's Mac OS 9 and macOS support USB mass storage; Mac OS 8.6 supported USB mass storage through an optional driver . The Linux kernel has supported USB mass-storage devices since version 2.3.47 (2001, backported to kernel 2.2.18 ). This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling

770-605: A rated playback time of 35 hours with a 2250 mAh battery. Video battery life is unspecified. In addition to the "L" versions, the X5 also comes in a "V" variation, which lacks the FM radio. Cowon announced in May 2007 that the X5 series had been discontinued. Its successor, the X7 series, was slated to be released at some point in the summer of 2007, but was delayed until October 2010. The iAUDIO M5

825-585: A single USB port may function as multiple USB devices, one of which is a USB mass-storage device. This simplifies distribution and access to drivers and documentation, primarily for the Microsoft Windows and Mac OS X operating systems. Such drivers are required to make full use of the device, usually because it does not fit a standard USB class or has additional functionality. An embedded USB mass-storage device makes it possible to install additional drivers without CD-ROM disks, floppies or Internet access to

880-445: A single charge, and the usual Cowon supported codecs: MP3, WMA, WAV, OGG Vorbis, and even FLAC for lossless audiophiles. Apart from FM radio, voice recording and line-in recording , it also featured video playback as well as photo and text viewing. The interface symbols indicate that it has an inbuilt FM radio and voice recorder. This 2-gigabyte device weighs 39 grammes and measures 34.4 x 72.9 x 16.7 mm. In June 2007, Cowon announced

935-401: A single charge. In July 2013, the iAUDIO 9+ was released. The unit has exactly the same physical and technical specifications as the original iAUDIO 9, except for a slightly larger internal speaker and JetEffect v. 5.0 (the original iAUDIO 9 was released with JetEffect v. 3.0). The Cowon iAUDIO 9+ comes in three capacities (and two colours): 8GB (white), 16GB (black), and 32GB (black). It has

990-464: A standard USB control interface). The USB Attached SCSI (UAS) protocol, introduced in USB ;3.0, fixes several of these issues, including command queuing, command pipes for hardware requiring them, and power management. Specific USB 2.0 chipsets had proprietary methods of achieving SCSI pass-through, which could be used to read S.M.A.R.T. data from drives using tools such as smartctl (using

1045-438: A vendor website; this is important, since many modern systems are supplied without optical or floppy drives. Internet access may be unavailable because the device provides network access (wireless, GSM or Ethernet cards). The embedded USB mass storage is usually made permanently read-only by the vendor, preventing accidental corruption and use for other purposes (although it may be updated with proprietary protocols when performing

1100-539: A wide selection of formats. It was first introduced to users of the Cowon D3 Plenue with the upgrade to firmware version x.55. An online version of JetVD, called JetToy , exists in beta stage . Other software developed by Cowon includes the iAUDIO LDB Manager , a small application for tagging music files with timecoded lyrics displayable on Cowon media players as well as in JetAudio . Cowon also offers

1155-499: Is 4 mm thicker and has a longer battery life. Unlike the M3, the X5 comes in 20, 30, and 60 GB variants. It is likely that there will be no 60 GB X5L, as the 60 GB X5 itself is the thickness of the 20 and 30 GB X5L due to the increased size of the hard drive. The 20, 30, and 60 GB capacities offer a rated battery life of 14 hours for audio playback with a 950 mAh battery. The 20 and 30 GB X5L models specify

1210-508: Is a little larger and heavier than the iAudio 8. All Cowon media players, starting with the iAUDIO 4, feature a set of sound enhancement technologies collectively referred to as JetEffect, including a technology known as BBE+ , licensed from BBE Sound, Inc. The distinction between JetEffect and BBE+ is not always clear. On Cowon media players, the JetEffect menu offers the following options: The latest version of JetEffect, JetEffect 5,

1265-647: Is a set of computing communications protocols , specifically a USB Device Class , defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an external hard drive; the protocol set interfaces with a number of storage devices. Devices connected to computers via this standard include: Devices supporting this standard are known as MSC (Mass Storage Class) devices. While MSC

1320-476: Is basically a simplified version of the X5. It lacks an FM Radio, a colour screen (it has a greyscale screen instead), and USB-OTG functionality to save production costs. Its casing is a silver color instead of the black X5. There's also an "L" version available, which features enhanced battery life. The "L" version of the player is a little thicker and heavier though and costs slightly more. Introduced in July 2005,

1375-483: Is completely format-agnostic, enabling the industry-standard 'direct encoding.' WMA, OGG, ASF, WAV, and MP3 music files can be transferred between PCs and Macs using USB 2.0 or direct input. The device has a 20GB storage. When the M3 was released there was a lot of controversy about it, because the actual unit had no display. All but a few basic functions had to be controlled via the included remote control. Some people liked this concept, others were not so fond of it. When

1430-514: Is not well-supported and lacks features such as partitioning and general blocking. The Xbox 360 and PlayStation 3 support most mass-storage devices for the data transfer of media such as pictures and music. As of April 2010, the Xbox 360 (a) used a mass-storage device for saved games and the PS3 allowed transfers between devices on a mass-storage device. Independent developers have released drivers for

1485-486: Is the original abbreviation, UMS (Universal Mass Storage) has also come into common use. Most mainstream operating systems include support for USB mass storage devices; support on older systems is usually available through patches. Microsoft Windows has supported MSC since Windows 2000. There is no support for USB supplied by Microsoft in Windows before Windows 95 and Windows NT 4.0 . Windows 95 OSR2.1, an update to

1540-548: The Cowon iAUDIO 9 was released, more than two years after its predecessor, the i7 . iAudio 9 has a 43mm x 95mm x 8.6mm dimension, a weight of 40g, menu button and volume buttons on either side of the player, 8/16GB of memory, music and videos found on FM radio. It features a new vertical form factor and improves upon its predecessor by the inclusion of a built-in speaker. The iAdudio 9 also supports files including MP3, WMA, FLAC and WAV files, as well as WMV and AVI videos. The iAudio 9

1595-525: The SCSI transparent command set , designating their subset of the SCSI command set with their SCSI Peripheral Device Type (PDT). Subclass codes specify the following command sets: The specification does not require a particular file system on conforming devices. Based on the specified command set and any subset, it provides a means to read and write sectors of data (similar to the low-level interface used to access

1650-493: The TI-84 Plus and TI-84 Plus Silver Edition to access USB mass-storage devices. In these calculators, the usb8x driver supports the msd8x user-interface application. The USB mass-storage specification provides an interface to a number of industry-standard command sets, allowing a device to disclose its subclass. In practice, there is little support for specifying a command set via its subclass; most drivers only support

1705-472: The 1GB and 2GB units have black accents. It has a size of 3 by 1.4 by 0.7 inches and weighs around 1 ounce. The iAUDIO X5 was released in April 2005. The X5 uses much of the same hardware as the M3, and as such has much of the same features and capabilities. It has almost identical features to the iriver H300 Series. The X5 includes a color screen on the unit. As with the M3, there is an "L" version which

The latest version of JetEffect, JetEffect 5,

1870-531: The U3 using the provided software from Cowon. The player can also display JPEG and TXT files. The support for audio files was also enhanced from previous models: the U3 was the world's first Flash-based player that was able to play FLAC files (but only from compression rate 0 to 2 with the initial Firmware v1.11. It now supports up to Q8 with V1.13). Another new feature was the U3's powerful sound output of 30  mW per channel (at 16  ohm , achieved by utilizing

1925-550: The USB specification) without a self-powered USB hub . A Windows Mobile device cannot display its file system as a mass-storage device unless the device implementer adds that functionality. However, third-party applications add MSC emulation to most WM devices (commercial Softick CardExport and free WM5torage). Only memory cards (not internal-storage memory) can generally be exported, due to file-systems issues; see device access , below. The AutoRun feature of Windows worked on all removable media, allowing USB storage devices to become

1980-452: The company as “Cowon iAUDIO” or simply “iAUDIO.” Outside the domestic market, Cowon iAUDIO's sales and market share have always been minuscule - however, it gained a certain niche market and retains a loyal following from fans and enthusiasts. In its marketing, Cowon distinguishes between " MP3 players " and " portable media players ," where the latter are larger and have a greater focus on video playback. The categories differ slightly between

2035-425: The device without partitioning, making it start from sector 0 without additional boot sectors, headers or partitions. The other uses a DOS partition table (and MBR code), with one partition spanning the entire device. This partition is often aligned to a high power of two of the sectors (such as 1 or 2 MB), common in solid state drives for performance and durability. Some devices with embedded storage resembling

2090-423: The drives are placed in a disk enclosure that supports a USB mass-storage interface. Some USB mass-storage interfaces are generic, providing basic read-write commands; although that works well for basic data transfers with devices containing hard drives, there is no simple way to send advanced, device-specific commands to such USB mass-storage devices (though, devices may create their own communication protocols over

2145-470: The features that users of the CW200 and CW300 had been missing. Upgrades from previous players came in the form of UMS standard, BBE sound processing effects, line in recording and a 124 colour backlight LED display. This player used the STMP 3420 chipset by Sigmatel . The iAUDIO M3 was introduced March 2004. The player was Cowon's first DAP with an integrated 1.8-inch (46 mm) hard drive. The iAUDIO M3

2200-551: The iAUDIO 7, a player based on the iAUDIO 6 but with 4, 8, or 16 gigabytes of flash memory instead of a hard drive. The OLED screen from the iAUDIO 6 model was replaced by a TFT with 260,000 colors (18 bit colour depth). The device used a swing-control. Audio recordings could only be saved in WMA format, with a user selectable bitrate of 64, 80, 96, or 128 kbit/s. The device played MP3, WMA, FLAC, Ogg Vorbis, WAV, and ASF audio files as well as Xvid videos. The frame rate of video playback

2255-446: The iAUDIO CW200. The CW200 had audio playback capabilities, an FM radio and voice recording through a built-in microphone. This player also had a revised model, the iAUDIO CW250. In December 2002, Cowon released the iAUDIO CW300. This model was essentially an iAUDIO CW200 using AA batteries as a power supply. Most reviewers also regarded it as having a higher build quality. The iAUDIO 4 was introduced December 2003. It came with most of

2310-518: The iAUDIO F1 can be described as an iAUDIO U2 with an interesting design, a colour OLED display, and higher power output (32 mW vs. 20 mW for the U2). The F1 played Vorbis , WMA , WAV , ASF and MP3 files and could tune to the radio, as well as record from the radio. It could also record directly from sources or record using a built in microphone. It came in 256 MB/512 MB/1 GB sizes of Flash memory. Introduced in October 2005,

2365-415: The iAUDIO M3 was first released outside of Korea, there was a quality issue with the player's remote control. There was a widespread "fading" issue, in which the text of the remote slowly disappeared. This issue was rectified by the rapid recall of all faulty remotes and free replacements. The iAUDIO U2 was introduced in July 2004. It was also Cowon's first player to feature a navigational joystick instead of

2420-414: The iAUDIO U2 and G3. The iAUDIO 5 was relatively similar to the aforementioned players. What set it apart from other players was the fact that it had 1000 different backlight colour combinations. It was powered by an AAA battery which allowed for a maximum playback time of up to 20 hours.The device's colour is determined by the memory size; the 256MB model has red accents, the 512MB model has blue accents, and

2475-470: The iAUDIO U3 was the successor to the iAUDIO U2. The main difference between the two players was that the U3 featured a color screen (260,000 colors, 160×128 resolution) which allowed playback of MPEG4 videos encoded in XviD , as well as picture display. Like the iAUDIO X5, the U3 only played video files at up to 15 frame/s with a resolution of 160x128. Most videos must therefore be converted to be played back on

2530-460: The new Telechip TCC770 audio chipset and Cirrus Logic CS42L51 Codec). Like the U2 the U3 had a built-in lithium polymer cell for a playback time of up to 20 hours. As with all iAUDIO devices, there was no need for the use of software, since the U3 was a UMS device (though additional software was required to take advantage of some features, such as converting video to the right format to be played back on

2585-415: The operating system, featured limited support for USB. During that time no generic USB mass-storage driver was produced by Microsoft (including for Windows 98 ), and a device-specific driver was needed for each type of USB storage device. Third-party, freeware drivers became available for Windows 98 and Windows 98SE, and third-party drivers are also available for Windows NT 4.0. Windows 2000 has support (via

2640-593: The player). With the firmware version 1.20 Cowon added ID3 browsing and DRM capabilities to the U3. This made the U3 the first iAUDIO player that allowed the user to browse its contents by the contents of ID3 tags embedded in the files. Features: The iAUDIO was presented in January 2006 at the CES in Las Vegas. It was the first digital audio player to feature a 0.85-inch (22 mm) hard drive. This technology allowed

2695-449: The production of a high capacity digital audio player in a very small form factor. In August 2006, Cowon released the iAUDIO T2. The T2 was a necklace type audio player. It featured a color screen, though it did not support video or photo viewing. Features included FM radio, voice recording and Cowon's traditional wide codec support: the T2 supported MP3, WMA, Ogg , and WAV audio files. FLAC

2750-615: The spin-up and spin-down of hard disk drives, and other options). Mobile devices running Android 6 or higher also support USB mass storage through dual-role USB on USB-C ports, and USB-OTG on older ports. Solaris has supported devices since its version 2.8 (1998), NetBSD since its version 1.5 (2000), FreeBSD since its version 4.0 (2000) and OpenBSD since its version 2.7 (2000). Digital UNIX (later known as Tru64 UNIX ), has supported USB and USB mass-storage devices since its version 4.0E (1998). AIX has supported USB mass-storage devices since its 5.3 T9 and 6.1 T3 versions; however, it

2805-589: Was a cheaper version of the G3 which was introduced in the spring of 2005. It lacked some of the main features of the G3: no FM radio, the interface was only USB 1.1 (compared to USB 2.0 on the G3), and the playback time with a single AA battery was down to 40 hours. The iAUDIO 5 was introduced in November 2004. It was the successor to the popular iAUDIO 4 series and was powered by the same Sigmatel chipset that were used in
