Most data can be compressed at an approximate 2:1 ratio. For instance, data compressed at a 2:1 ratio would provide a total drive capacity of 30 GB for the 15/30 DLT Drive and 70 GB for the 35/70 DLT Drive. -
Page 12: Scsi-2 Controller Requirements
Overview The maximum transfer rate with data compression ranges from 2.50 MB/s for the 15/30 DLT Tape Drive to 10.0 MB/s for the 35/70 DLT Tape Drive. To achieve these maximum data transfer rates, the data compression ratio must be greater than 2:1 and you must have software that supports the higher transfer rate. -

If inserting a data cartridge again lights the cleaning indicator, it may mean a damaged data cartridge. However, the DLT Drive will still try to read the tape and may even be able to do so successfully. If you think the tape is damaged, back up the data onto another cartridge, and discard the old cartridge. - Page 48 ......Tape Drive Cleaning If the “Use Cleaning Tape” indicator stays lit after the cleaning cartridge has been used and unloaded, the cleaning has not been done and the cartridge has expired.
