Hi all,
I have a Chinon FZ-502, 5.25" FDD unit, 360 kb (afaik). I used it to build an external unit for two portable PCs (you can read about it in this thread:
http://www.vintage-computer.com/vcf...-FDD-out-of-an-internal-one-(is-it-possible-) )
I discovered this drive can read perfectly the disks made by another PC (I used both xcopy /v and fc /b /v commands to compare source and target) and, also, it seems to be aligned: I used the alignment test from the "Image Disk" software.
When I try to write a file on it, i got a "general failure" or "data writing failure" error.
Formatting, it returns a lot of bad sector (I formatted with Format Master with the verify=on option). The floppy disk itself is ok (I tried many of them: they can be formatted without problem by my XT clone).
Of course I already cleaned the headers and I tried with two different cables (both tested and known to be good, though).
I tried to set the TERM jumper open or closed (yes I know it can't be the problem, but...)
Any idea?
