I made a terrible mistake.
I wanted to format my computer.
I booted from the windows xp CD I deleted all partitions on my computers.
I didn't think that my USB harddrives would show on the list of harddrives so i deleted the partitions on them too!
I DID NOT FORMAT them, just deleted the partition, it took a second.
Please tell me I can get my data back! and how.
I used "recovery software" in google.
it led me to RecoverMyFiles wich I tried and it did everything I wanted. All my files are saved!
Just know that the free version doesn't allow you to save the files you find... I had to get the full version.
