I bought two Samsung HD203WI disks recently. I ran a complete bad blocks test before I began using them. Today I found this in dmesg output:
sd 4:0:0:0: [sde] Unhandled error code
sd 4:0:0:0: [sde] Result: hostbyte=0x04 driverbyte=0x00
sd 4:0:0:0: [sde] CDB: cdb=0x2a: 2a 00 da 24 97 d8 00 02 a8 00
end_request: I/O error, dev sde, sector 3659831256
This repeats over and over again.
I tried using smartmontools on the disk, however:
2 root@dude ~ # smartctl -a /dev/sde
smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build)

A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
I'm using this disk in a RAID1 array, and so far there's no sign of a degraded array. Can anyone comment on the state of the disk? Is this a bad drive?
