File system errors after shutdown

I have no idea what to do or how to prove what the issue is so I am asking here for advice so I dont make things worse through ignorance.

My desktop PC is now reporting a file system with errors after every shutdown. First it does a check during the boot process then goes to a (repair filesystem) command line.

Running fsck fixes a load of problems then the system will boot normally.

The main HDD is 3xSATA in RAID 5 configuration.

I am running Suse 11.1 64 bit with 8GB RAM on an Intel Quad core processor.

The machine is built from components and has been working faultlessly for 3 months.

My only thoughts are that maybe an update has had an unexpected side effect or that the Mother Board has an issue though it could also be a disk problem but I would have thought that the RAID would recover from that.

Any suggestions on what I can do to track down the cause much appreciated.


I am not a RAID expert but had several cases of HDD failing throughout the years.
Hardraid or softraid?
Did you check the integrity of the disks with a programm from the producer? Which brand(s) are your HDD? Do you have tried to enable SMART to see if one of them gives errors? - The latter is not very reliable but may give useful hints if errors present.
