What did you do to wipe the drive? Partition, format or both?
If you partitioned it, I don't know a way to recover it. If you just did a quick format, the data is still there, you then need to find a program to recover it.

See if it has a restore partition from the factory. Turn on the computer and hold the F11 key, see if you get a restore computer option. If so this will restore it as it came from the factory.
