Basically for the past few months the hard drive has been going on and off randomly on the pc that it was attached to. By on and off i mean the system cannot detect it at times. SO any way because it was an old 5/6 years old machine i figured it's time for upgrade any way so i removed the HDD and replaced the machine with one of my newer once an i7 etc etc. The machine i replaced it with has 4 hard drives including an SSD so everything works fine on it picture perfect. However upon inserting the hard drive of doom the entire system crashes and burns to ashes. Basically it keeps looping the windows loading logo endlessly. Further more to test this theory i put the 1TB drive that creates the issues on my actual gaming rig after i insert the drive i get the exact same issue. So in short every computer that this drive gets hooked up on does not work. And since i can still access the BIOS on all the computers i noticed that the drive has about 4000 cylinders rather than the usual thousands it has. My question is has anyone ever encountered a similar problem and if so is there any possible solution rather than throwing the drive out.
