SCSI Write protect not properly detected

Hi,

With 2.5.73 the write protect on my SCSI MO drive (via Firewire IDE enclosure) is not being detected properly. It always says the write protect is off. The drive itself is properly being detected as an Optical disk.

<snip>
SCSI device sdf: 605846 2048-byte hdwr sectors (1241 MB)
sdf: Write Protect is off
sdf: Mode Sense: 00 56 03 80
sdf: cache data unavailable
sdf: assuming drive cache: write through
sdf: sdf1
Attached scsi removable disk sdf at scsi2, channel 0, id 0, lun 0

With 2.4 it works properly:

SCSI device sdf: 605846 2048-byte hdwr sectors (1241 MB)
sdf: Write Protect is on
sdf: sdf1

Cheers,

Jurgen
