Further Format issue on BBC 8271 with Disc Utilities #67

Closed kgl2001 closed 6 years ago

kgl2001 commented 6 years ago

BBC Micro, 8271 controller, DFS1.20, FF 0.9.14a, index-suppression = no

Following on from ticket https://github.com/keirf/FlashFloppy/issues/57, I have been able to generate a format error when running a disc test with Disc Utilities. The format part of the test starts at track 80 and works down to track 1. It failed at track 19:

Sounds like a plan. More than happy to continue testing. Also happy to loan you some Beeb hardware for testing, if that would help.

Thanks, that's definitely an option! We might do some more digging and see if this is a Beeb-specific problem first, and also I will work on some stressy write tests, probably on Amiga as it has a flexible software-controlled FDC and I'm quite handy with Amigas :)

Okay v0.9.16a is released. I'll call that done for this ticket.

Obviously there are still problems. I'm interested if 9.16 does seem an improvement over 9.15 in the end. I think it probably is. But either way please do open a fresh ticket so we can pursue the remaining problems afresh.

Did some testing with my write/read/compare test and the older version (0.9.14a & 0.9.15a) failed even quicker than the ff_67_10 or 67_9 version (on the 1st pass of 100 random seek/write/read) they failed with a write error, on 67_10 I was getting read errors but seemed it had messed up the track as i had to reformat each time to continue. Will give the new 0.9.16a a go and see how it performs.
