I was reinstalling win xp on a computer .. so first I connected an external HDD and backed up the data. Then I booted with winxp CD and then I deleted all partitions shown ..and one of the partitions shown there was the External HDD bcoz it was still connected. I immediately disconnected it and checked on a different computer and it shows up as unallocated. Please help me recover the data because it not only has the current backup but also many other important backups. Thanks.
