Hi, I found a few things on the net about this but nothing helped so far. We get the error: Warning: /pci@1f,0/pci@1,1/ide@3/dad@0,0 (dad0): uncorrectable data error: block 410 ... on the server and it just keeps rebooting. I booted from cd and did a fsck on all the disks, but it didn't help. Is there anything else I can try??

Thanks

Do you mean other than replacing the disk? Not really.

If this is a SCSI system you could boot off CD and use format to verify the disk and replace out bad blocks, which will work if there are only a few. However, it's been my experience with modern disk drives that the appearance of one bad block is very shortly followed by the complete failure of the disk. And besides, there's a good chance that the suspect blocks contain data that is required for proper operation of the system. Even if you sucessfully replace the block there's a good chance that you'll have a non-operable system.

The best course of action would be to get a new disk drive and re-install the OS. With a running system you could then attempt to recover data from the failling drive, if you don't have good backups.

Boot off install cdrom with " boot cdrom -s "

Run "format", goto verify menu and run disk scan to check for bad blocks.  compare the bad block(s) to the partition map and see what filesystems it effects and recover any data you need. I recommend getting another disk and recovering though.

Enjoy.

I really should have examined the question more closely...

Forget the stuff about SCSI drives as the question quite clearly indicates that this is an IDE drive. So your only option is going to be to replace the drive.

You might want to check out the bug reports before doing anything.

For instance, you can get this in S8 on the Ltra 5/10 if you take the system down to runlevel 5 with the shutdown command.
There are som other bugsreports too on this matter

So before replacing any hw, check sunsolve.
