HD floppy in 3000D

[lofstudio]

I just got a Chinon 357A floppy drive for my 3000. So far, I haven't had any luck reading any HD floppies.

When I put a PC-formatted disk in, I get a message: "Error validating File Allocation Table in device PC1. Results uncertain. Proceed at your own risk." If I try to format it, the dialog box says it'll be formatted as a 1440K disk, but a PC or Mac only recognizes it as 720K. If I try to format it as an Amiga disk, I can only format it as 880K. The drive reads 880K disks fine.

The HD pin seems to work okay. Any thoughts?

Thanks!

Unfortunally I have no idea of the answer to that one, since I never have used an hd disk drive.

But I have another floppy related question.

The floppy cable in the 4000, is supposed to be straight, not "twisted" as the pc cables, when you just have one drive?

Then why not start a new thread. :-(

Yes, use the connector before the twist, jumper set to DS0

Hi,

how many disk drives have you installed?  Which drive is the HD one if more than 1, (df0 or df1)?  If you have a normal (dd) one as df0 and the hd one as df1 swap them so hd is df0.  If hd one is df1 change the motherboard jumper to dd for df1!

Thanks for the suggestion. I swapped them last night, so the HD is df0 and the DD is df1, and the HD works now, unless there's a disk in df1 (same error as before).

What's this jumper you're talking about? The only jumper I was aware of is 351, to enable df1.

By the way, in answer to a previous question, KS/WB 3.1.

Ok, shows the 1.76 is working!

The jumper is the disable/enable one (brain not working), I seem to remember something about setting it to disable if a 1.76 is set as df1, well can't find the reference to that for the 3000 but it is the case for a 4000.

Is the cable the original that came with the 3000 or a PC one?

Not had this problem as had 2 1.76 drives!  Can't remember what jumper was set at though, was a while ago.

@lofstudio

There are jupers on the back of the floppy drive.
"ds0" is for DF0 and "ds1" for DF1.
Hope this helps.
