I deleted by mistake a FAT32 (I think it was fat32) partition in a external drive, searching I got through this post: http://www.tomshardware.co.uk/forum/229699-14-erased-partition-external-hard-drive-mistake-help but trying all the nice tools they talk there the problem is, as the drive is external, it's not even listed among the recoverable drives. It's a 2.5'' portable hard drive, so I don't have a free slot where to insert it as an internal drive.
What can I do to recover the partition? I'm using Windows
Thank you
