Hi,

I had a failed hard drive (corrupted boot sector) on my Vista machine
running Outlook 2007.

I am able to see/recover most of the data from the disk. However, I cannot
find my Outlook.pst file anywhere on the hard drive.

Please let me know if there is any way I can recover my data.

Thank you!
