Zero-byte pst file after chkdsk on Win2K3 Server

[RyanC]

I recently had to restart a win2k3 server machine in order to replace the UPS. Upon reboot it forced a disk check, which was allowed to proceed. After the disk check, one of the users' Outlook PST file was reduced to 0 bytes and is, of course, unreadable.

The file in question resides on a raid 5 array on an intel ich8 controller.

I've made some attempts to recover this with data recovery software, but nothing has turned up.

Anyone have any ideas?

Thanks,
Ryan
