Jumanji, thanks for your help to this point, and I'll read your post about GPT vs. MBR.

Kaktussoft, I ran the commands you suggested as Administrator, and here's the output:

Disk 0 is now the selected disk.

DISKPART> select part 1

FYI, I'm heading to work and taking the drive with me to troubleshoot there. I'll be unavailable for about 30 minutes, or longer if things are already crazy at work.

Many thanks,

Gentlemen,

FYI I'm now at work, and my Win 7 Ultimate x64 laptop here has the same problem with the drive. In Disk Management it is still showing up as "Not Initialized" "Unallocated". So far, that is 3 Windows 7 Ultimate x64 machines that don't recognize that partition.

Do you have a spare large harddrive? If so... delete its partitions or at least shrink them ... so at least 2 TB unallocated space is on that drive. Afterwards in PW ... Copy the StM_Movies_00_-_Ez partition to that space.

Is the new partition working as expected and can you assign a drive letter?

Kaktussoft,

It sounds like you're saying the partition can't be recovered on the drive it's currently on, and I need to use PW to copy the content off to a new drive.

I'll have to wait to do that until later. I have plenty of retired 2Tb drives, but they're at home (the drive is here at work with me) so I can't start the copy now.

Before I try that, it seems to me that since PW can see the partition details, there may be a Unix or DOS tool that that would allow me to fix the partition information through command prompts.

Or is that just too risky, and I should just copy off the data while I can?

In any case, nothing I have tried so far has made the partition visible to Windows, or allowed me to assign a drive letter, either in PW or Windows.

Many thanks,

April

In PW I can see the very small and large partition. But in win7 it's not partitioned at all!! How come.... I don't know.

Truly! That's why I asked for help.... because even though the partitions are visible in PW, they won't recover and I can't assign a drive letter.

I won't be home for a few hours, and until then, I won't be able to copy the files to a new drive. If you have any other ideas I'd be happy to try them.

Many thanks,

April

The partitions have been recovered by PW. They are visible in PW (after recovery) and stay visible all the time. Correct?
That's why I want you to (try to) make a partition copy. At least you have a backup then.

Well, the partition that I want to recover has always been visible in PW when I scan for it. From the beginning, I have not been able to assign a drive letter to it, and Windows won't see it. Truly, it's always wise to back up data *first*. I'll start that copy when I get home. Since it's over 2Tb of data, I expect that to take a while. Many thanks, April
