The USB Removable Disk Drive consists of a docking station, which holds a removable disk drive. The docking station is available as an internal or external device. The disk drive is a backup and restore device that can be used as an alternative to tape drives. The removable disk drive is not a replacement for regular disk drives and cannot be used as part of a disk array. The following illustrations show the internal drives.

For best results, use only the removable disk drives that are shown in Table 1.
The removable disk drives are a supply item that can be ordered as a feature code. To order in the United States and Canada, call 1-888-IBM-MEDIA. To order drives in other locations, contact your local provider of IBM® storage products or see Storage Media (http://www.storage.ibm.com/media/).
The removable disk drives are not a service item. IBM service representatives are not dispatched to service or replace the removable disk drives.
Store removable disk drives in their protective containers, on a flat surface with the top side up. The storage area must be clean and dry, must have normal room temperature, and must be away from any magnetic fields. For best storage life, use the removable disk drives every six months.
The internal docking station can be connected to the internal USB media device connector on the system backplane of POWER7® processor-based systems.

USB Removable Disk Drive is supported on the following versions of operating systems:
The disk drive is a backup and restore device that can be used as an alternative to tape drives. The removable disk drive is not a replacement for regular disk drives and cannot be used as part of a disk array.
AIX names the drive usbmsx, for example, usbms1, and usbms2. AIX also can use the device as a raw device, for example, rusbms1 and rusbms2.
AIX uses the removable disk drive differently depending on the program being used. The AIX mksysb command builds a list of files to back up, creates a universal disk format (UDF) file system, and puts a boot image and the root volume group on the removable disk drive. When the mksysb process is complete the removable disk drive can be used to boot the system. If you mount the removable disk drive, you can display and copy files to and from the UDF file system on the removable disk drive.
The AIX tar, backup, restore, dd, and cpio commands can write to the removable disk drive as a raw device or nonraw device. You might get improved performance by using the device as a raw device.
See the AIX documentation for additional information.
IBM i configures the drive as a removable media drive with a name in the format RMSxx, for example, RMS01.
The drive and cartridge are used with optical commands and utilities (for example, WRKOPTVOL and INZOPT), and reports media in the QOPT file system.
See the IBM i documentation for information about using IBM i copy and backup commands.
Linux configures the drive as a disk drive with a name in the format sdx, for example, sda, sdb, and sdc.
See the Linux documentation for information about using Linux copy and backup commands.
The removable disk drives have a red, write-protect tab that is located on the back of the drive. To write-protect a drive, slide the write-protect tab toward the lock symbol. To disengage write protection, slide the tab to the unlock symbol.
