While the biggest interest on this forum seems to be the upcoming cloning tool (which I am currently working on), I would like to point out something that HDDSuperTool can do now. It is known that some Western Digital drives can suffer from a firmware issue which causes them to be very unresponsive and slow. While there are other (free?) tools that can fix this issue, HDDSuperTool is the only known (free) tool at this time that can do it on drives that are USB only. There have now been a few success stories on other forums. I would like to point out that this does not work on all drives as it depends on the USB to SATA bridge on the drive, and some do not support the needed commands. But for those that it does work on, it can perform what seems to be a miracle.
