Drives
Your library can be equipped with either one or two drives. The tape drives are packaged in a common drive module that is designed so that you can easily
add an additional drive or replace a drive. For more detailed information on the drives, see
Specifications .
Media and Media Protection
Table 3 lists the types of media formats that are supported.
Table 3. Supported media
*Lower level media can be used in higher level drives; however, the capacity and transfer rates will be at the lower drive level. The library prevents higher
level media from being used in lower level drives when the media is correctly barcoded.
**DLT IV media can be used in the SDLT-320 drive as read only.
Using WORM Cartridges
LTO-3 media are available in Write Once Read Many (WORM) format. Data stored on WORM tapes cannot be erased or altered. The barcode applied to a
WORM cartridge uses the designation "LT". This ensures that the library manages the tape appropriately. For more information about barcodes, refer to
Barcode Labels .
If you try to write to a WORM tape that has been previously written to capacity, you will receive an error message. WORM tapes cannot be used to run
diagnostics tests.
Media Protection
The write-protect switch is used to prevent recording over existing data. To prevent recording or deleting, place the write-protect switch to the closed position
(right). The drive senses the position of the switch and will not allow writing in this position. When inserting cartridges in the library, place the switch in the
open position (left), unless you do not wish to record on a specific cartridge. Example media are shown in
Figure 5 and Figure 6 .
