John and David -
The V3.5 firmware appears to format 3.5" disks fine on my system.

It’s best to phone them however. Great source of chips BTW.

Hi John,
I have just got my ZFDC board working today after waiting 3 weeks for
a WD2793 to arrive from China (my first WD2793 from another US
supplier was dead).
I'm using ZFDCDIAG.COM to test the board, all my boards are
S100Computers.com boards, Z80CPU, RAM/ROM, Console, CF IDE board on
default ports.
On ZFDC firmware V2.8 everything seems to work fine, I can format a
3.5" floppy for CPM or DOS, I can perform random read/write tests all OK.
On upgrading to firmware V3.5 I noticed that the format disk command
'00' seems to send the ZFDC board into reset with the two left hand
digits clocking over (like before the board is initialised), disk
random read/write seems to be fine and read sector etc, it only plays
up if I try to format a disk
Reverting my firmware back to V2.8 and Format works fine.
Can you check on your board with a 3.5" disk to see if any bugs have
crept in to the latest firmware version.
thanks
David Fry
