I am running PC-Xenix on a PC-AT and have a bad sector on the hard disk.
Can someone tell me the best way to mark the bad sector. From reading
the manual I am not sure if I can run /etc/badtrack except at installation.
Any help you can give me would be greatly apprecaiated.
Thanks,
Bill

Sorry not to use 'r', but with the return path as long as it is, the probability of successful transmission is about zip ... I tried running badtrack on the disk when some bad sectors showed up with Xenix. The only good thing about the results is that I had formatted the disk only shortly before then, and so there was little information to be lost. I don't think the 286 has a large enough address space to allow fsck to clean up the resulting mess. It is possible that the bad block can be "fixed" by repeatedly trying to edit the affected file. Sometimes the 69th retry will actually read the block, at which time it can be rewritten. If this suggests that the disk driver error recovery leaves something to be desired, you're right. Otherwise, rename the file to something awful and forget about it until time for an unconditional reformat of the disk with the Advanced Diagnostics. If you are losing a block more than once in a blue moon, chances there is something wrong with your disk controller, or your drive is about to self destruct. My year old stock CMI drive has been very happy running 24 hours a days since the controller board was replaced early this year. Actually, it took a few unconditional reformats afterwards to get it really settled down. Just don't knock on wood if it is near the AT ... -- Chuck Forsberg WA7KGX ...!tektronix!reed!omen!caf CIS:70715,131 Omen Technology Inc 17505-V NW Sauvie Island Road Portland OR 97231 Home of Professional-YAM, the most powerful COMM program for the IBM PC Voice: 503-621-3406 Modem: 503-621-3746 (Hit CR's for speed detect) omen Any ACU 1200 1-503-621-3746 se:--se: link ord: Giznoid in:--in: uucp
