Add this to your dumpstoppers notebook, boys and girls. The program which can forward individual bad sectors on a uda50 drive is officially known as EVRLK and unofficially as "scrubber" among the techs. It was formerly known as "rabads". It appears on the rev 24 diagnostic tape, and most FEs have no experience with it. Caveat: by default, EVRLK will write a forced error (FER) on the replacement block. This seems to be the reason that the program warns you severely to do a backup before and a restore after using the program. If your goal is to avoid dump/format/restore you should answer "No" to the prompt "Enable write with forced errors", avoiding the FER mark and allowing you to attempt to clean up the disk with fsck after your bad sectors have been forwarded. Disclaimer: any time you patch the raw disk you are risking death at the hands of angry users! _____________________________________________________ Matt University crawford@anl-mcs.arpa Crawford of Chicago ihnp4!oddjob!matt
