Can't read CP/M disks on PC

[Vintage Computer Festival]

So now that I've got the 8" drive running well on the PC, I am trying to
read 8" CP/M disks.  22Disk is giving me sector not found errors
(cylinder 2, side 0, sector 1) and the DOS CP/M tools are giving me
"Unknown floppy disk format", even on disks that read fine on my NEC APC.

I tried reading in a sector using debug but I also get read errors.

Any ideas?

The drive is a Tandon TM 848-02.  Very little information online, but it
seems to support DSDD.
