Amiga "Compatible" floppy Drive?
« on: March 20, 2009, 04:00:48 AM »
I see a lot people put up on ebay PC Floppy Drives and add in the description Amiga compatible.  I saw this one listed - Mitsumi Newtronics 3.5" floppy drive, model D359T5 - but can't find anything about it to confirm the posters comment. I messaged him about the claim of being amiga compat, but a day later no response...

I have and Amiga 500 that needs a new internal drive - I took one out of a known working 500 and it works fine... but the one it came with just whistles loud and quits.  Any info or links to current drives that can be made to work with ease?


Thanks,
Mike Valverde

How about first cleaning your old drive?  Conversion is sadly not with ease.
Several reasons:
- not all models are the same, and even when they seem on label and outside, the pcb can be different.  Some pcbs can be converted some not so much.  
- Even some that one converts can be fleaky and not working properly.  I have one such drive - works fine on pc but not on amiga, even though the other one looks exactly the same.
- The time taken is hardly worth the effort (time to research, test drive).  I still have a few of these left, for sale, once sold it's unlikely i'm going to convert any as its too much work and too little return.  I've done mine as a winter exercise in 2008.  Yeah it may seem like $20-28 for a drive is a lot, but once you get into it yourself you realize that its a long project.  
- pc converted drives work best with high density disks (ok dsdd works too, but i found hd to be more reliable with pc mechanism) and hole taped up so it comes up as 880kb.  No matter what model you use.  (i have tested several myself).
- drives i have for sale are:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEUSX:IT&item=190287908542
and comes with 12 disks already tested on it.
- this Mitsumi drive may or may not work (see above):
Mitsumi Newtronics 3.5" floppy drive, model D359T5
I bet the seller has no clue about amiga and simply is trying to sell untested pc stock on ebay.  (I bought some cheap drives too, and the results were mixed, hence out of a lot of 12, i got maybe 6 to work properly.  3 were bummers, misaligned).  I'm not sure if that specific model is easy to do or not.  but if you're looking for adventure, it can't hurt to try???

if you are a DIY person with a lot of spare time, then surely google can help you ;-)

The D359T5 can be converted to a Amiga compatible drive. I have a bunch of them lying around, I think they are quite good.

Here is a guide in german. Short translation: Remove the bridge between DCH and solder it to RDY instead, wire the DCH pad to pin 2, desolder the drive select bridge from DS1 and solder it to DS0. After that, you have an 880k Amiga drive that will work perfectly as df0: even with X-Copy and NDOS disks.
