I have a Kaypro 10 running CPM 2.2 and have been receiving occasional 'System Status 02 - BDOS error'. I have run the CHECK program that came with the machine and have received the following errors on the hard disk: Verify error drive 1 cyl 280 head 1 sector 11 (unc) sdh=10101001 Verify error drive 1 cyl 303 head 3 sector 11 (unc) sdh=10101011 CHECK will also report the occasional correctable (cor) errors that clear up the next time it is run, but these 2 always show up. I have run FINDBAD on the disk and it neither reports nor locks out any bad sectors. Does anyone know of a program I could get that would allow me the option of selectively locking out bad sectors? I would like to fix this without having to buy a new hard disk. Any advice would be appreciated. thanks in advance, Mike Scott University of Rochester 716 275-9127

My Kaypro 10 had similar problems, and CHECK showed tons of errors on the A: drive. Most of the errors were in the directory area, and eventually it wouldn't even boot from the HD. I was sure I was in for a new drive, so after making sure I had a good back up (or 2), I ran FORMAT.COM, to reformat the entire drive. I then ran PUTSYS and PUTOVL, and restored the backed up data. Everything was fine. Curiously this happened another time, and I had to go through the same procedure. No further problems, and the Kaypro has had about 4 years of fairly heavy use since then. (I have my fingers crossed, though.) I don't know if this would help your problem, but anything's worth a try. Doug Allison UUCP: {most backbones}!gatech!hisata!doug
