I have a Flashcard 49, a disk on a card. I have been quite pleased with it except for some problems I believe are attributable to bad sectors that were not identified as such at the time it was formatted. Can anyone tell me if there is a program other than format (or fdisk.. whicever one does it) that checks a disk for bad sectors (not just reports those already LABELLED as bad but checks for new ones, too) withOUT formatting the disk? Until I can do this, I have a slowly growing number of files I have had to avoid using as they send DOS to Abort , Retry, Ignore. thanks. -- amlovell@phoenix.princeton.edu ...since 1963.

Look at the Norton Utilities. There's a utility that scans your disk for bad sectors, then marks them (in the FAT) as unusable if they're not currently in use, or warns you if they're already being used by a file. ----------------------------------------------- Bill Frolik Hewlett-Packard hplabs!hp-pcd!bill Corvallis, Oregon 97330

Norton 's DiskTest reads all sectors to see if they are readable. If a sector cannot be read, you are given the option to mark the corresponding cluster as bad. For files Norton will allocate a new cluster and will copy the sectors to the new cluster. Off course the data in the damaged sector cannot be copied (mostly) and that will have to be reconstructed.

There is a PD program done by PC Magazine called DISKSCAN which will read the entire disk and mark any bad sectors. It is not as sophisticated as Norton or SpinRite, but it is reasonably effective. You should find this on most any BBS hoctor@osiris
