I created a drive backup 3 years ago using Ghost 8.20 to DVDs. I have copied all the images to my hard drive and can open the backup, browse and restore certain files. But there are 3 large Outlook PST files in particular I need (3.5GB, 5.7Gb & 10.7GB), the 3.5GB files extracts fine and can be opened. Extracting the larger 2 produces no errors, but the extracted size is only approx 25% of the original listed size in the Ghost Image, and when trying to open the PST with Outlook it reports "not a personal folder". Any ideas? The Ghost Explorer I'm using is 2003.789
