Symptom: When using the DOS mirroring utility Dupli.exe, you can get a very long copy time on the order of several hundred hours.

Cause: This is caused by an internal error in Dupli.exe calculating the wrong drive size.

Corrective Action: You can fix this immediately by stopping the copy process, turning the power on the PC to off and restarting the Dupli.exe copy process. You will find that the copy time displayed is approximately 10 gigabytes per 30-minute interval. This would mean that a 30-gigabyte drive would take approximately 1.5 hours.

NOTES:

The new Dupli.exe version, available on our download page, fixes the problem without power down.
