[Techtoolslist] Samdisk looks very promising...

I have a local friend who works at Fluke.  I sent a hail marry mail to him.
Cross your fingers :)

Unfortunately the answer is Yes - you need a unserialized Service Disc 
for 6.0 or 6.1 to format your drive or CFC card. I don't know if there 
is a workaround other than a good image from a 6.1 drive - like one I 
have but haven't gotten around to uploading to TTL yet. You would need 
to use some image software like Miray's HDClone, or the free(?) Dolly, 
or similar. OSX folks may be able to use the Disk Utility to make the 
image, but you will need SCSI if formatting a drive, but you should be 
able to use one of those USB to IDE adapters otherwise.

I'm not having any luck yet with using a CF and my SCSI to IDE adapter - 
which works fine with hard drives, but can't handle the CF for some 
reason...

Trying to track a copy of Service 6.1 down. Mucking with the Serialized 
copy on TTL gives me CRC errors so I can't fix it easily. Looks like 
each sector is C6Fh in length - not sure where the serial is added 
though...darn.
