Question Error I have never seen or heard about before.

When trying to copy over one of my old VM image files, I'm getting this:

F:\VirtualMachineImages\2003SBSServer-WCSSRV>xcopy *.vhd d:\temp. /c
F:WC5SBBS2003Server.VHD
File creation error - Data error (cyclic redundancy check).

0 File(s) copied

Any ideas ? Computer runs perfectly.

Bad sector start backing up the HD.

To determine which drive (source or destination) is throwing the error, type the following commands from the command prompt:

cd F:\VirtualMachineImages\2003SBSServer-WCSSRV\
copy *.vhd nul

The command is a pure read action by copying the file to the Null device (i.e. never-never land). If this command completes without a problem, the destination drive D: is the failing drive. It it throws an error, the source F: drive is the failing drive.

Thanks guys !

CRC error, sometimes you can get them from a bad/loose cable too.
There likely is no bad sector accompanying this.
Vibrations, many drives/fans, bumping the case. Cosmic stuff ... I wouldn't worry about it if it's not continuing to happen.
