I have a USB 2.0 Memory Stick, 8 Gb, FAT 32 formatted....

Apparently it has 2 Gb of bad sectors in it somewhere....

Now I'd like to know :

(a) If there's a tool which can tell me (and if possible display graphically) which sectors (whenever data gets copied it can be traced as to which sector it goes into right ??) are corrupted....

(b) If it's possible to repair these sectors, if not, what is a solution in such a case ???

[In my knowledge the answer to (b) is NO, as bad sectors are like bad magnetic strips and if they're corrupted they cannot be repaired, and yes one can intentionally copy unusable or unneeded data into those sectors and then leave them be so that u can assume that u have 6 Gb only ]

Relpppp !!!

chkdsk should be able to do so.

chkdsk f: /r

assuming F is your USB drive.

Also when bad sectors are found, they are marked unwritable, so newly written data is not written on bad sectors. after a chkdsk scan it reports total size, bad sector size and available free space.

You dun understand.... It doesn't say bad sectors are found....

I forgot to mention : I formatted the USB using FULL format, then ran checkdisk (from Properties menu with and without options like check for bad sectors and revive them etc etc).... Then I did the following :

I inserted the USB and copied 1.83 Gb of data into it.... I safely removed it ; then re-inserted it.... 2 of the 3 files had disappeared, they weren't hidden or anything.... The third file took like ages to copy back to the HDD, when I tried to play it directly from the USB (using WMP) the WMP gave errors.... It basically means that all files were corrupted and screwed....

Your turn....

Found this software :

It's taken like 3 hrs but it shows the files which were copied (but if I deleted them how come they are still shown ???)

yes, that is a data recovery software, see if you can successfully restore back data.
Your entire USB drive might be corrupted.

But if my USB is corrupted how does it allow data to be transferred ???

And I did finally get that software to reveal the transferred files (which I thought were lost) but that jackass said "Demo please buy".... Will "buy" it ; he he he....
