Me again

I have a problem on other machine with drive mentioned in subject. From time to time it gives raw read rate error in SMART and windows says that i need to replace the drive (second picture). After reading smart in hdat2 or mhdd and seeing there is no error in smart, hdd scan in windows also gives no error (first picture). I've tried to RMA it twice but shop returned it and said that drive is 100% functional.

Any idea how to RMA this drive?

[labtech]

Not sure you can. There is no solid evidence there is something wrong with the drive like you said.

It is possible that the issue is elsewhere, maybe a bad data cable, port issues, etc.
Have you tried troubleshooting any of these in any way?

[Misko78]

Tried it on three different machines. Issue arrises only after some time of use. If I move it to other machine it gives no error.

It is unclear if on other machines EVEN AFTER SOME TIME of use it gives or not an error :

1) IF the drive AFTER SOME TIME and ON EVERY MACHINE gives errors, it is an internal problem (can be diagnosed reading some internal data but it is beyond end user) and in my opinion should be RMAed.

2) If the drive GIVES PROBLEM ONLY ON ONE MACHINE and you can't diagnose it immediately I would check in this order the power supply and motherboard.

Some drives are more sensitive than other to a certain class of "problems" (too technical to explain here and unfortunately I'm not allowed to, also) so they work better on some systems and poorly or badly on other regardless of functionality.

On every machine, but the problem is that some time can be a week. As i said I've tried to RMA it but shop gives me explanation that they did tests and that drive is OK and as a proof I've received screenshot from Hitachi DFT. I can't RMA it directly to HGST because Serbia is not on a list of supported countries.

Tried selling it?

[Misko78]

Why would I want to sell a dodgy drive to anyone? I have a warranty and i would like RMA it, but unfortunately drive doesn't show any signs of defect while at shop, 'cause they test it for hour at most.

EDIT: Now it shows error in MHDD and HDAT2 S.M.A.R.T. read attributes, but after offline short self test, error disappear.

Well, I meant something else. I meant selling it as a part or something. Take a little loss. Buy new drive. Back to annoyance free.

Best wishes.

I can't offer a solution or an explanation, but it seems very strange to me that the Worst value for the Raw Read Error Rate attribute does not remain at 1. Apparently it is not a lifetime worst value, which begs the question, how is it determined?

Thanks, but selling it for parts in Serbia is not doable, poor small country = small market. Will try to anyway.

I can't understand how it is possible either. I see many different readouts after it "repairs itself".

It seems that my warrany exired few days ago drive was manufactured on 27.03.2009 but i had 3-year warranty when i bought it.

1. Is it safe to use this drive (for non important data)?
2. Is it possible to fix it?

[BlackST]

1) Maybe

2) Yes but not by you.
