Hi,
I have a 2TB external fat32 disk which I was using in windows and mac.
I created a 200GB fat32 partition in windows then instructed time machine to format the partition (HFS+???) in order to create a time machine backup.
The disk is now unrecognised on windows and files are only viewable using data recovery software on mac.
Testdisk is taking hours to do a quick analysis. Perhaps there is a method to undo what I did?
Much appercated if you are able to help
Thanks,
Alan

There is no method to recover overwritten stuff.

You can try out Testdisk to see if remaining parts of your partition can be restored based upon a backup sector in FAT32.
Using Photorec would yield good results when defragmentation was low on your partition.

When being unhappy with loosing metdata like subdirectories and file names a commercial recovery program might recover this metadata as well.
