After using Acronis Disk Director Suite® version 10.0 (build 2,160) on my Win XP Pro SP2 system Microsoft's "Computer Management | Disk Management" tool's partition map now shows that my 465.76 GB hard disk drive is now 901.51 GB in size. It also shows spurious/nonexistant "Unallocated" space of 405.26 GB right between my D: and E: partitions and spurious "Free Space" of 30.50 GB between a Healthy (Unknown Partition) System partition (30.00 GB, logical - by mistake) and my Healthy (Boot) partiton (30.01 GB). Disk Director's own partion map does not show these spurious entries but it was DD 10 that I used to create and manage the partitions on my hard disk drives. So far my system seems to be working OK and I have backed everything up but, while waiting for Acronis tech support to get back to me (from 19 March) I have to keep it running. The last thing I want to do is panic Needless to say, though, I am freaked out. Potentially corrupted partiton tables, or whatever else is going on, is frightening. I miss Powerquest. When it was good, it was very good. (or maybe my memory isn't what it used to be. ) Does anyone have any insights? Thanks.
