A friend of mine is having great difficulty in getting his home-brew
hard disk to work correctly.  Here is the problem.

We are using a CMI 6426S 20 meg hard disk, an Adaptek 4000A controller,
and an Apple SCSI card (Rev. C).  We hooked it up using a combonation
of purchased and built cables (the cables I built were tested for good
connections first).  The drive powers up fine, but when we tried to do
some low-level formatting, we got a PRODOS ERROR 27.

Any suggestions?  Could it be that since the drive is BRAND NEW, and
that the article in A+ said that you might not be able to do any low
level formatting with an Apple II series, that this is the problem?

Any help would be greatly appreciated.

Thanks,
