Hello!
To be able to use the Hitachi 2.5" HD, 120 GB as an USB device, the
following quirk needs to be set:
DA_Q_NO_SYNC_CACHE
Excerpt from /var/log/messages:
<<<
May 8 12:48:43 jupiter kernel: da0: <Hitachi HTS541212H9A HP4O> Fixed
Direct Access SCSI-2 device
May 8 12:48:43 jupiter kernel: da0: 40.000MB/s transfers
May 8 12:48:43 jupiter kernel: da0: 114473MB (234441648 512 byte
sectors: 255H 63S/T 14593C)
May 8 12:48:43 jupiter kernel: umass0: Invalid CSW: tag 7 should be 8
May 8 12:48:43 jupiter kernel: (da0:umass-sim0:0:0:0): Synchronize
cache failed, status == 0x10, scsi status == 0x0
>>>
Adding the following to scsi_da.c solved the prolem:
{
/*
* This particular Hitachi drive doesn't like the
* synchronize cache command.
* Reported by:
*/
{T_DIRECT, SIP_MEDIA_FIXED, "Hitachi", "HTS541212H9A*", "*"},
/*quirks*/ DA_Q_NO_SYNC_CACHE
},
