---- I am currently involved in adding a hard disk to our Explorer post's CP/M 2.2 system. The controller I have is from Western Digital, and makes writing the BIOS a breeze. My only question is: How do I mark bad blocks? I would like to put an undeletable file in those blocks which are bad. Is this possible? Any and all suggestions are greatly appreciated. Thanx in advance. Ted Estes AT&T Teletype Corp. Skokie, IL ...!ihnp4!tty3b!estes

Try FINDBD54.ASM, on SIG/M disk 67. It can be downloaded from
SIMTEL20. I don't remember the file name, but it's listed in
micro:<sigm>sigm.crclst at SIMTEL20.

Ted, I tried FINDBAD, a CP/M public domain program available on one of the SIG/M disks and also available via FTP from SIMTEL20 (can get you specific pointerss if interested). It seems to work OK on floppies (though sometimes it doesn't find ALL the bad tracks - don't know why!), but never tried it on my hard disk (a Morrow- provided 5-Megger with my Decision I) -- scared, I guess! My hard disk formatting program seems to do a pretty good job of locating bad sectors - at least it never found any, and I never get a bad sector error! However that formatting program is proprietary, so I can't give it to you. I THINK there was an older Morrow hard disk formatting program also at SIMTEL20, but don't have the pointers right here and don't remember the details (I looked at it out of curiosity but had no need for it). Sorry I can't be of more use,but maybe this'll point you toward something useful. Regards, David Kirschbaum Toad Hall (ABN.ISCAMS@USC-ISID)
