hi, i recently ran HD tune to scan my drive and it found 0.1% bad sectors

WD lifeguard utility smart test fails, extended test finds bad sectors but could not fix it. all smart stats OK
win7 error checking found no problems on the drive.
HD tune all smart stats ok, found 0.1% bad sectors.

funny thing is there is 0 reallocation attempts count in SMART
and there are 54 sectors pending.

how do i make it reallocate the sectors?

IF the WD util fails the SMART test you should see those errors in any utility you run and maybe even in the system BIOS (if supported). I do not know any way to force a reallocation in Windows. My understanding is that whenever these sectors are remapped it is detrimental to drive efficiency so I would either RMA the drive (if under warranty sounds like a great idea) or I would try to contain the bad sectors in a small partition which you would then not use, losing drive space in the process.

What's the difference between a "current pending sector" and a "reallocated sector"?
I have 1 pending sector but the rest is OK, is this enough of a reason to warrant a RMA? I also did CHKDSK on all partitions including the system reserved 100mb partition, and everything was absolutely perfect 0 bad files 0 bad sectors so is everything ok or is there a problem with my HDD? It's a WD caviar blue 1TB 7200rpm.

if western digitals smart tool fails the drive it I would absolutely RMA it. no point to holding on to a bad drive till the warranty is out
