I have a bootable CF drive, using an old version of DOS on an older voicemail system
I need to clone same
Source is a 4 GB drive from an existing working system, destination is a 4 GB drive.
I go through the process
Look at the destination disk
All info seems to be there.
Yet none of the 4 drives I've tried to clone, will boot.

I don't see how I could screw this up, but nonetheless, the cloned drives won't work

Any suggestions ?

HDD GURU has works well on SD drives, and other SmartMedia cards I've used on other systems.

Any timely help would be appreciated.

Perhaps there is an ATAPI - ATA identification issue?

You could use HDAT2 to send the ATA Identify Device and ATAPI Identify Packet Device commands, and then capture the outputs to 512-byte files for analysis with a hex editor.

See the references to "fixed drive" on pages 26 and 47 of this specification:

Notice that word 0 of the Identify Device info block differentiates between a fixed drive and a removable drive.
