Today I picked up my drive from Umart and I was not charged the $35. I still think the drive is faulty but I can see why there is nothing they can do about it. So what they've suggested is check out my PSU and, like seagate said, the drivers. Well I know psu's cause a lot of HDD problems so when my case was getting rather full last year I went and bought a new psu to keep up (because the original one was something like 250W and if you've seen my computer you'd know that's not enough..). So now there is nothing for it except to wait for the drive to die and report an error code or something else to fix it. At the moment I don't have anything against Umart either.
