Time-Out Values

Load 10 minutes
Unload 10 minutes
Rewind (full tape length) 10 minutes
Space/Locate 20 minutes
Erase (long) 5 hours
Erase (short) 5 minutes
Write/Write Filemarks 5 minutes
Read 5 minutes
Read/Write Attribute (MAM), with 1 KB of attribute data 1 minutes
Non-tape movement (such as TEST UNIT READY, INQUIRY) 1 minutes

Notes:
These values are for a single SCSI command in non-Immediate mode. As most commands will be sent in Immediate mode, status will be received by the host typically within 20 ms. In such cases, the time-out given indicates when the drive will have completed the operation and be ready for the next tape movement command.
All of these values may be subject to change.
There is no retension facility.
Where relevant, the figures above apply to 200 GB (at 2:1 compression) media.
