Disk I/O Error after upgrade

Hello, I am running NW2004s SP10 on a Windows XP 32 bit system w/ MAXDB ver 7.6.

I tried to apply an upgrade to SP 13 and now my database will not start nor can I connect. I get the following in the DB trace:

2007-12-20 11:23:45 0x968 31 SrvTask Permanently reserved 13 servertasks for 'Backup / Restore'.

It looks like a disk error, but I am not sure. I was having no issues prior to upgrade. Could it be the upgrade corrupted the DB or could I actually have a bad disk?

    Yes, it is (it was before). I will try uncompressing it. Is that the right way to go?

    Did you compress your database files (using Windows' compress filesystem settings)?

    Uncommpressed the data and log files and was able to start the DB. I believe the files got compressed when a disk cleanup was run prior to the upgrade to free up disk space.

    Thanks for the help!! Points awarded!!
