External dual-slim HD floppy drive only seems to work as 880k?

Thought I'd ask here since I posed a question at the end of this photo-booth post:

The drive appears to only be recognized as 880k on my A500 (2.05), A1200 (3.1) and A4000 (3.1). I've read about other units like this that needed a driver and was wondering if that was the issue and where the driver might be found?

There are some switches on the back of the drive -- a "0/1" set to 1, and a 3-state "A/0/B" set to 0 -- but flipping the switches and restarting didn't seem to make a difference for the density shown when attempting to format an HD disk.

Thanks in advance!

Replied on there... I'm now pretty convinced it's not an HD floppy suitable for the Amiga, but it's merely using an HD floppy mechanism

I have an external floppy drive, single drive, with a HD PC mechanism on it and it works as 880KB not as 1.76 HD drive, it has a special circuitry to make it compatible with Amiga but only in 880KB, I put a Chinon Amiga drive on it and doesn't work, so I pretty sure that you have a modified PC drive like mine.

Regards

Thanks for the replies -- Figured out it was a Power Computing drive and I tried a few of the "Power Computing XL" drivers which looks like the only model it *might* have been but they all report 880k still so I believe you're correct -- these appear to be HD floppies but are meant to run in 880k mode -- but at least they're fast and quiet.

@chiark -- on the off chance your driver is different than the ones I found I'd take a copy to give it a try -- thanks.

Either way it's fine by me, they do what I need and I got a good deal on it. The main reason I grabbed it was that I'm considering replacing the internal drives on a few machines like my A500 and A1000 with HxC SD memory card units and wanted to make sure I could still read and boot actual floppies without a hassle. :smile:
