Technical FAQ - Will Data Recovery Wizard work on a hard drive larger than 137 gigabyte?

Yes it will work under the following conditions:

1. The BIOS must be capable of handling these drives. Many BIOS needn't upgrade but you might have to upgrade the BIOS or use another computer. See more...

2. You need Windows XP Service Pack 2. Please read http://support.microsoft.com/default.aspx?scid=kb;en-us;303013 for more information.

Check Windows' Disk Management tools. If it recognizes the drive with its correct size,  Data Recovery Wizard will do too.
