Has anyone seen this:

I create an NTFS partition, and all is fine.

Then, after some drive-inensive operations such as file copying or defrag, the partition simply disappears? Windows disk manager reports it is unallocated space. Partition Magic as well as Acronis Disk Director all report it as un-allocated space. During file copying, I received a message that thus and such directory was corrupt and the directory could not be read. Previoulsy, the directory was just fine. All AVI files played perfectly. No issues at all.

This has happened *twice* now to me within the last few days on a new 300 GB (Maxtor) drive I was archiving raw video footage on. I have never had this phonomena before. I lost about 8 hoours of analog to digital footage. It is all recoverable, however, 8 hours of run time has now been wasted.

Some specifics:

1.) This is drive #10 in my tower of drives.

2.) I ran the latest (long duration test) Maxtor diagnostics and all said the drive was fine.

3.) Initially, an Acronis Disk Director-created partition disappeared after a defrag operation. (Primary partition)

4.) The second partition to disappear was a standard-stock (native) Win XP Pro-created NTFS partition during a large file copy operation. (Primary partition)

5.) This is a fixed drive on an IDE cable. IDE #2, slave.

Has anyone else ever seen this? I certainly have not.

**I was wondering if maybe my power supply (300 watt) was not big enough, could this be a factor? I do not have any spurious reboots, crashes, etc. My systrem runs terrific.

Any insight would be most helpful. I would like to work this out before redoing my lost archive footage.

Thanks much!
