I thought a low-level format should map out bad sectors so the OS does not "see" them. This does not appear to be happening with your low-level formatting tool.

I formatted a disk using Windows XP disk management and it correctly reports 253,000 KB in bad sectors and a reduction in total disk space, as expected. Then I formated with your low-level formatting tool, Windows XP now reports 0 KB in bad sectors and no reduction in disk space. I think your low-level formatting tool is dangerous and should not be used! If I were to continue using this disk, as-is, I would experience file corruption because the bad sectors were never identified and mapped out by your low-level formatting tool.

My experience with low-level formatting is that you typically execute microcode on the HDD controller which maps out the bad sectors. The result is a reduction in total disk space and the OS reports 0 KB in bad sectors.

I think you should rename your low-level formatting tool to "advanced format tool".

I think you shouldn't use it.

I guess for most people your low-level formatting program will work fine if there disk is good. Plus your program is free!! However, I have an old disk that corrupts files due to bad sectors. I need to map out these bad sectors somehow. Hmmm... they're must be a way....

hmmmm
check it...

The idea of this tool is to blank the drive and the data to the maps of bad sectors this allows many of us with software based errors to get a fully working HDD, after using it you use another program to scan for errors like HDDScan. I'm sure it was in the instructions somewhere about this.
