filesystem problem

[Guest]

2 seperate systems, both with 1 tB raid 5 storage, different raid controllers
but both using windows xp pro, raid arrays of each mapped to the other as a
network drive.

both machines have the same problem - all data on the raid arrays has
changed to 0kb and is unreadable to the os.
this setup worked flawlessly until about 2 days ago when both machines had
the same problem occur at the same time.
both machines have nod32 antivirus running with latest updates.
no virus has been found on either machine.

anyone know what could have caused this? or how to possibley fix it?
my best guess is the data headers or file db has become corrupt, the only
other explaination besides a new virus that is as yet undetected by the AV
software is that both machines were updated via the windows update site 3-4
hours before this happened and an update dissagrees with large raid arrays.
(all other drives in both systems which are not raid are unaffected)

have tried rebuilding the arrays with no change in situation and data
recovery software is also showing all files as 0kb.

Just a theory - either somehow the wrong controller drivers got
loaded for you RAID control card -or- something updated the
partition and/or file system tables on the RAID configuration
directly, without going through the controller card RAID driver.
Either way, you may be able to recover the files, with some high
priced (corporate version) software, unless you have backups.
Either way though, you need to find out what corrupted the drives or
you may end up in the same boat again.

thanks for the reply, however....
raid controller drivers are the originals that have run smooth for almost 2
years, nothing new has been installed/used other than what was added by
windows update and recovery software which was added after the fact (at this
point im becoming convinced that whatever microsoft sent in the updates has
killed my files and quite probably just cost me a LOT of money in lost
earnings)
and to top that off the recovery software im using is top drawer corperate
stuff - had to be to fully support nondestuctive recovery of a raid5
partition - which means im out even more cash since it still sees 0kb
