Nebulon Posted March 16, 2017 Share Posted March 16, 2017 I've got a 1040 STe that is having intermittent disk read issues using the internal diskette drive. These same disks have been verified as good on another STe. On the problem machine, if I pop the disk out and back in again, it quite often finishes loading data successfully. Thoughts? If it turns out to be some kind of controller issue, how hard is it to replace the diskette drive controller circuitry on an ST? Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted March 16, 2017 Share Posted March 16, 2017 It seems rather as mechanical problem. So, replacing drive should be first test - and that's easier than replacing controller chip. Quote Link to comment Share on other sites More sharing options...

I agree. I also think it's mechanical and likely a simple drive replacement. just wondering though -- if it did turn out to be a circuitry problem, is it as easy to fix as swapping a chip on the motherboard?

Nebulon Posted April 26, 2018 Author Share Posted April 26, 2018 Here's a question: What happens if you open the case on an external single-sided Atari diskette drive and replace the innards with a double-sided drive? Would it actually work as a double-sided drive or is there a chip that needs to be changed too? Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted April 26, 2018 Share Posted April 26, 2018 If floppy drive would cost something more, a lot more, then it would be worth to deal with some changes. As it is low cost component forget whole idea. Really. Change whole drive to DS one. Quote Link to comment Share on other sites More sharing options...
Nebulon Posted April 26, 2018 Author Share Posted April 26, 2018 Ah yes, but I have a NOS DS/DD internal Chinon drive just sitting here, waiting to be put to use... Quote Link to comment Share on other sites More sharing options...

What that NOS means ? Waiting to use - so use it .. Ahhh.... I think that you meant case in which drive is, not case of drive self Like SF 354 . Yes, replace whole drive.

I think that you meant case in which drive is, not case of drive self Like SF 354 . Yes, replace whole drive. NOS - New Old Stock. So I took it apart. It turns out that for this particular external drive, the power and data connectors are totally different than 'standard'. So it looks like the solution would be to just get a totally new drive and enclosure as you mentioned. Quote Link to comment Share on other sites More sharing options...
