![]() ![]() This is likely because lacking detailed knowledge of the way the file system is using the damaged sectors simply revectoring them elsewhere would leave any files (or, worse, any file system metadata) that had used them corrupted because the file system didn’t know the sectors no longer contained what they should and/or because the user might want to use an application like Unstoppable Copier to make a more thorough attempt to reclaim any missing data than the disk and/or operating system did. [ don’t know of an application which will do what you’d appear to like Disk Scanner Pro+ to do (force the disk to allocate replacement sectors to replace any unreadable ones without affecting – e.g., wiping – the surrounding data). To check this, look for a tool from your drive manufacturer to read the SMART data the controller writes to the disk. Also, the disk controller should automatically map out bad sectors, replacing them with good sectors from a reserved pool of sectors, so if you see bad sectors at all, it may mean that pool is used up and drive is failing. Much better to replace the drive if there are many bad sectors. Then you have a bunch of new drive letters and a drive that is failing anyway. A comment in another forum (sorry, I don’t remember which one) said it takes a LOT of work to manually block out sectors by creating partitions of good and bad areas. So Macrorit’s program is good if you want a nice display or want to see IF you have bad sectors, and don’t want to fix anything, or if you want to manually do something about any bad sectors found. “chkdsk /r” does that plus it attempts to recover any data from the bad sectors. The “chkdsk /f” command in Windows (command prompt as admin) looks like it will search for bad sectors AND flag them to prevent future use. “Red” would mean nothing to the operation system or disk controller. [ Where do you see that it marks bad sectors? The descriptions here and on Macrorit’s web pages only say it “marks them in red”, presumably on the status display, so you can see where they are graphically. ![]()
