Samsung HUtil is a DOS based utility for diagnosing problems with Samsung hard drives. On our disk recovery system here at Home Helptech, it fails to boot for some reason. The disk boots up into DOS but fails with a “Copy Fail” error. I haven’t been able to find any mention of this on the web so I thought I’d note that there is an easy work around.

Then the disk boots up, press the F8 key

After that, you need to step through the start up procedure line by line by pressing the Y key.

Eventually, HUtil will start up normally, without the Copy Failed error

Now you can continue using HUtil as normal.
