Microdrive failure after felt pad detaches - ideas?
Posted: Sun Jan 26, 2020 11:27 am
Hello all,
I've been reading the forum for a long time but haven't needed to post until now. Yesterday I was copying some old programmes from microdrive cartridges I had found in a box to disk. All was going well with both microdrives on my QL working normally (as they have done since I got it in 1984/5). Unfortunately as a cartridge was being read in mdv1 it made an unpleasant noise and stopped reading. When I pulled it out I saw the felt pad had disintegrated.
On putting a different (known to be working) cartridge into mdv1 I got a "Not found" message. It read correctly in mdv2. I powered down and tried again. The second time I tried I still get a "Not found" in mdv1 for all cartridges and mdv2 now continuously spins the tape but never returns any data.
I've taken the QL apart and both motors are turning, the pinch wheels and tape heads seem clean and the pinch wheels haven't worked up their spindles. When I turn the QL on and press F1, mdv1 spins up and down as normal. However, it decides very quickly - a matter of a second or two - that it has "Not found" anything when I do "dir mdv1_". "dir mdv2_" just spins forever.
Does anyone have any ideas?
Many thanks
Mark
P.S. The QL itself is still working correctly with my Trump Card and floppy drive.
