ntfs corruption after snapshot delete

hi

we have an ntfs disk (holding SQL databases) which has gone corrupt.  chkdsk fixed it, but a couple of reboots later, windows said the volume did not exist and disk manager wants to initialise it now.

Obviously it's beyond help.  We have a backup we can restore from, but we really need to establish WHY this has happened so we can be confident it won't happen again.  We're wondering if our recent vmware update is the cause.  This is what we did -

took snapshots over several weeks

upgraded vmware from 4.0 to 4.1

upgraded vmware tools from 4.0 to 4.1

upgraded vmhardware 4 to 7

week delay

deleted snapshots from the VM

the server is running windows server 2008 R2 and the server (& SQL) were running (but quiet as it was saturday) at the time the snapshots were deleted.

so we're wondering if 4.1 has had problems deleting snapshots taken under 4.0?

thoughts?

thanks

(sorry in advance if this kind of multi-post is considered rude, but we're desperate to know what went wrong)

keeping snaps over several weeks is really not  a good practice.....even if there were any corrupt state in any one of the snashot disks and u delete/commit it to the base disk the entire vm disk goes into a corrupt state.
