Hello all.

Last week I started having serious problems with one of my drives. Some 'delayed write' error on my $MFT. And afterwards chkdsk and norton disk doctor kept reporting a small ammount of bad sectors.

I RMA'd it and had a cross-ship sent to me. I received the new drive today and recovered my data from the faulty drive. In the process I had to reboot several times after the transfer crashed my computer and I had to wait for the faulty drive to cool down before I could start over. In the end all my files were transferred successfully.

I then did a 'quick format' on it and then ran chkdsk with the option to scan for and try to recover bad sectors.

When I now run norton disk doctor on the faulty drive, it now says there are no more bad sectors. I feel kind of bad sending the drive back now if there's no bad sectors on it ! Though I don't fully test the report.

I was just wondering.. can bad sectors be fixed with a full format ?? I'm going to send it back one way or another because I really don't trust it, specially after the clicking noises and beeps it made today when I was trying to recover the data.. but why is it showing no bad sectors anymore ??

The full format marked those sectors as bad so they won't be used. If you do a low level sector by sector scan, you will find those bad sectors.
