harddisk "Write Protect" bit

This is really nerve-cracking.

In one PC, my USB drive's dmesg output is:

sd 2:0:0:0: [sdd] 312581808 512-byte hardware sectors (160042 MB)
sd 2:0:0:0: [sdd] Write Protect is off
sd 2:0:0:0: [sdd] Mode Sense: 00 00 00 00
sd 2:0:0:0: [sdd] Assuming drive cache: write through
sd 2:0:0:0: [sdd] 312581808 512-byte hardware sectors (160042 MB)
sd 2:0:0:0: [sdd] Write Protect is off
sd 2:0:0:0: [sdd] Mode Sense: 00 00 00 00
sd 2:0:0:0: [sdd] Assuming drive cache: write through
 sdd: sdd1 sdd2 sdd3 < sdd5 > sdd4
sd 2:0:0:0: [sdd] Attached SCSI disk


But in another PC, the output is (just the relevant entry):

"Write Protect is on".

Why?   Because of this write protect, I cannot mount it as read-writable.

Thanks.
