no options for formatting 5.25 floppy disk

I'm thinking your problem stems from the TWO Jumpers on SS1.

in order to solve that issue?Ģ) Have you any clue about what every jumper bank means? I also wish to find a way at least to swap it from B: to A:ģ) What about the seek error on the drive that doesn't read the disks?Ĥ) Any other clue about old floppy disk drive care, cleaning and refurbishing are welcome! The questions for you are the following ones:ġ) Do you know if I'm going wrong formatting, or is there anything I can try / clean / lube / check / etc. SS2 - options: DA - HL - RA : missing jumper bank (no jumper on the PCB) Now, this kind of drive has six jumper banks, so I'm trying to understand their meaning.

^_^Ībout the unit that doesn't read the disks: the disk spins, the heads move, but I get a seek error reading drive B. Honestly I don't remember how I used to format 5.25' floppy disk, I believe the last one I formatted was in the beginning / middle of '1990s. I tried in the following ways (default, it tries to format 360k): Any disk content is erased during this attempt to format. I always get an error about invalid 0 track, bad disk. I tried many floppy that *seemed* to work (since they're old floppies, I can't be sure they are really good). Maybe, in order to change it from B: to A: there's more to change into the jumper banks.?Īnother issue: I can't format a floppy. I tried to swap it from B: to A: with a blind change into the jumper bank (SS1 from 1 to 0, see below the jumper table) and now it's checked at boot as A: drive (of course, bios was set accordingly) but if I ask a DIR when it's set as B:, it works same thing when it's set as drive A:, I got a general failure on drive A: - of course with the same floppy disk inserted. (btw I'm testing them in a Ms-Dos 6.22 environment) I will start to talk about this third one. I've recently got three Epson SD-600 5.25' floppy drive: one is surely broken, one that doesn't read the disks, and the third one seems to work, more or less.
