Keywords: disklabel, 386bsd Message-ID: <1992Aug6.003014.11815@cc.uow.edu.au> Date: 6 Aug 92 00:30:14 GMT Organization: University Of Wollongong Lines: 20 I have just installed 386bsd-0.1 on my 200 Mbyte IDE drive for the first time using the install command on the Tiny 386bsd disk. Everything went very smoothly - thank you very much to the Jolitz's and their helpers. I am now considering a reinstallation in order to tidy up the disklabel. Reading over earlier postings to this group I notice that several disktab entries proposed for IDE drives give them the bad144 type sector forwarding attribute and leave a few cylinders for this purpose. On the other hand, the install notes clearly state that "bad144 is never used with SCSI or IDE disks..." I have had sectors go bad on an IDE drive (under DOS). Can bad sectors be dynamically remapped on an IDE drive, and, if so, can the wd driver cope with this? If not, is there any point in keeping a few tracks spare just in case? Is it the case, as the install notes seem to imply, that bad144 remapping cannot be used on an IDE drive? Thank you Paul Nulsen pejn@wampyr.cc.uow.edu.au
