| Hello,
Do you get any error while running the command "dmesg"? If yes, please have your Datacenter perform a hard disk check to see if there are any bad blocks/errors with it.

| Oops...it looks like your server is dying..please take a backup of the disk, if you have any valuable data in it... and then have the DC perform a hard disk check. Most probably you may need to replace the disk.

| so maybe this error occur due to cable issue?

| Well don't guess. Have the datacenter take down the box, and switch the drive. It's only a backup drive, so no real lost. They can test the drive at their own leisure.

| Contact your DC soon. It seems the drive is failing. Ask them to run an fsck to see if it can fix it.

| i am running my own box so i can not ask DC to help in this case,so i need to test the disk,any guide to do this?
thanks for all help

| when you see "SCSI error", it means there was a hardware level error, and fsck wont fix it, but may make the problem worse.
since your primary disk is still working, it's most likely the secondary disk is failing. disks, like cars, eventually fail. unlike cars, you don't repair them, you just replace them. don't bother trying to save it, replace the disk now. there's very little chance the cable or controller would be bad, and only affect the second disk.
your disk is a Seagate Barracuda 7200.10 250GB drive (ST3250310AS). You may not be able to get an exact replacement, but since this is just a backup disk, get something that's similar in spec and around the same price; SATA II (3.0gbps, not SATA 1.5gbps), 8mb or 16mb cache, 7200rpm. OEM is fine, don't worry about any "RAID Edition" drives, they wont work better for your server.
