The problem is simple, during a windows XP install, there was an external drive attached to the computer(with disk images and such), and that drive was mistaken as a partition and deleted.
Luckily , after checking, the Data is still on the disk, but we can't acess it.
Is there a way to get back the data stored on it?
Its worth it to point out the drive was not formatted, it is simply the partition that was mistakenly deleted.
PS: The disk is a SeaGate FreeAgent*Desktop external drive if it's any help.
