So after my first successful attempt at fixing an HDD(viewtopic.php?f=1&t=29187), i am back for for another round. First i would like to mention that this is entirely for my learning experience. The data on these drives are in no way important. Having said that, any suggestion i get is viable, whether it be "fling it against a wall" or "flush it down the toilet".

Okay so running a scan in MHDD practically gets me all UNCRs with a few AMNFs. I don't know the relationship between LBAs and Sectors so ima just say MHDD reports the drive has LBA: 625,142,448. LBAs 0 to about 250,000 read fine(<3ms), after that it's downhill with UNCs and AMNFs. I know this drive is quite possibly undergoing mechanical failure but my intentions are to learn the steps in properly diagnosing mechanical failures and what exactly is failing here. To answer the foremost and most important question: No i get no clicking sounds.

Drive Model: WD3200BEVT-22A23T0

Seem that your drives are going all to fail, you would considering to change your computer power supply or the motherboard (or both).
Try to do a surface scan in MHDD by using another computer which you know for sure that it's not faulty.

I opened this drive and had fun with it's inners. I dumped the firmware modules before i destroyed it and will attach for the firmware junkies.
