Still Errors After CHKDSK
MY computer is quite new, so I know my HDD isn't old or anything.
After my 2nd reinstall of Windows 7 64 bit, I ran CHKDSK /R to check for any errors etc. It seemed to find some and subsequently fix them.
But, I ran Disc Doctor , which just kinda checks if there are errors or not, and it said that there are still errors.
I have run CHKDSK twice and there are still, apparently, errors.
Since my HDD is new, I am rather confused as to why there seem to be errors even after CHKDSK.
Any thoughts?

chkdsk checks for logical file system errors, if it finds a bad sector it will mark it as such in he OS table. A true disc diagnostic looks at the physical level, not the logical lie the OS, so a physical bad sector, while marked as bad in the OD table, may not be marked in the drives internal g-list of bad sectors and will be tested again by diagnostics. chkdsk does not handle physical errors correctly and is more designed to correct file structure issue. MHDD will mark sectors correctly. There is a non-destructive test that is pretty good, but to ensure the bads are mapped correctly, the destructive test is required, which will need a re-install after being run.
Any disk with bad sectors should in my opinion be scrapped. It can't be trusted, will only get worse, and I for one would not want to trust my data on such a drive. It's pointless trying to put off the inevitable when a new drive no longer costs the small fortune it once did.
Run the disk maker's diagnostic software on it for confirmation. The maker will insist you do that before returning it for refund or replacement.

Some bad sectors are always expected on a drive. I could count the number of drives on one hand I have seen that were brand new and had no entries in the p-list. Drives transparently handle bad sectors the issue is when they begin to grow too fast. It may well appear to the user that there are no bad sectors due to remapping those sectors, but with the tools to read the p-list and g-list, you see just how many there are. The p-list is the 'permanent list' of bad sectors, those that were identified even before the drive left the factory. The g-list is the 'grown list' of defects, those that the drive fixes on the fly during it's ooperational life. Trust me, if you could see that and wouldn't use a drive with bads, you would go through a LOT of drives till you found what you are looking for. The problem is, bads are ONLY remapped when written to. If data already exists when the sector is found bad in a read operation, the drive cannot move the data because it cannot guarantee the data will be read in a useful manner. There are utilities like MHDD that handle this, but chkdsk and most drive utilities do not handle it at the physical layer, and only add it to the OS table, which is wiped clean next time the drive is formatted
