Hi,

try,

dd if=/dev/rdsk/cxtydz of=/dev/null bs=1024k

Hope this helps.

And when you run Sanjay's dd command, what you're looking for is I/O errors. If you get one, that means the disk is bad. If the dd completes without complaint, then your disk is OK.

Run fsck or fsck -m if you just want it to check and not fix any errors found. You'll need to run this for each file system included on the drive in question.

And most important: make sure the online diagnostics are loaded and running. They will monitor disk error messages and can be configured to notify you when there are error messages. The file: /var/adm/syslog/syslog.log will also have disk errors logged.
