At least Maxtor OneTouch III require a "start stop unit" command after auto spin-down before the next access can proceed. This patch activates the responsible code in scsi_mod for all Maxtor SBP-2 disks. https://bugzilla.novell.com/show_bug.cgi?id=183011 Maybe that should be done for all SBP-2 disks, but better be cautious. Signed-off-by: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx> --- Applicable to Linux 2.6.17 and 2.6.17-mm2, can be easily adapted to older kernels. Sorry for the cross-post but I need testers. I don't have Maxtor enclosures (affected or unaffected) and none of my FireWire disks needs this patch.
