I have a 4.3GB 2.5" Toshiba hard drive in a Panasonic ToughBook running WIN98SE. (It's not so tough anymore). I started having disk write errors and crashes After running Troubleshooter-Hard Drive Analyser, I have, (so far it's still running at this writing), found 4 unmarked bad tracks. One of the track errors indicated address mark not found. I am not using even 25% of the drive's capacity since essentially this unit is used for testing purposes only. I am looking for a utility like the IBM/Hitachi Drive Fitness Utility for this drive that can flag sectors and tracks bad and remap them to alternative addresses. Toshiba's tech. support indicated they did *not* have such a utility. If I remember correctly when doing this with other brands of drives in the past (with their respective utility), I did not necessarily have to do a reformat of the drive afterwards and could potentially keep the O/S and drivers intact (don't have the system or driver disk anymore, had to manually download them the last time of an O/S reload). A new or refurbed disk drive seems to be a little pricey for this old of a laptop. Any help with this?
