Files deleted due to clustering issues?

Hey there,

I have to start by precising I am not a DBA, so my question might not be totally clear...

I have encountered an issue with shared drives on a server - my colleague and myself could not save files on any of the drives on this server, but there was enough disc space and we could still access the drives. My DBA mentioned the drives were offline and clustering services off (not sure what that last part means). The problem is after fixing that issue, all files saved on these drives for the last 5 days went missing. These were not in a single folder (we can rule out a false manipulation), but in all sub-folders any file or directory created/saved in this timeframe disappeared and files saved prior to that were still there...

Any clues how this can happen?

Many thanks.
SK
