no, not even with a reformat. you MIGHT get something with the manufacturers "re-format" tools but keep in mind that the way that these tools work is they simply wipe out the "grown defects" list in the disk drive, then re-test all of the defect areas that had been listed in the grown defect list, any that test out bad get added back into the list.
IDE/ATA/SATA drives all auto-remap bad sectors on the fly to a set of "spare" sectors in a special area of the disk. What you have going on is a drive with an increasing number of bad sectors, to the point that it has used up all of it's spares and the auto-remap can't work anymore, so now the drive is starting to report the sectors bad. What a wise person does in this scenario is go buy a new disk, and "dd" the contents of the old disk to the new disk. What the unwise person does is continue to screw around with the old disk, trying various things, until one day the entire works crashes and cannot be recovered.
