Can you write here symptoms of HDD, HDD id data as FW, ROM ver, ..., whitc tools do you have, and so on


thanks i advanced

Sounds like typical firmware corruption, maybe a bad head.

Need pro tools etc...

Hi,

Thanks for every answer.

I'm asking in order to better understand the issue... if the problem was with the head, wouldn't the HDD still be recognized/detected by the BIOS?

I just had a similar issue with one of my drives (a WD15EARS)
The drive spins up, but the motherboard's BIOS won't detect it or recognize it... and it takes forever (tested using different SATA cables on 2 different systems).

I was told that this was mostly a corrupt firmware issue, or problems with the circuit board (or one of the chips on it).

I'd say it's most likely a PCB issue. Do you have any way to read/write the ROM codes?

Reason I say that is that if the issue were the heads, the drive likely wouldn't spin at all, or would click like crazy.

If it sounds like a normal start up (spins up, normal bit of grinding, then silence) it's probably the PCB. However if you hear a loud click or beep, then it spins down, you might be looking at bad heads.

No i don't... I'm going to have to send the drive away for repair to make the data accessible again.

Thank you for your help and for answering my question.

The chances are very low, but it wouldn't hurt to gently remove any oxidisation from the HDA contacts with a soft pencil eraser.

yeah, I see what you mean. Nearly all my recent WD HDDs have had this issue.

Would you recommend using something like alcohol or other solutions to clean the contacts?

Sorry, I have to politely disagree. Seen loads of these with typical (to this series) firmware issues, never a bad PCB causing the symptoms described.

Not having a go, just sharing my experience with this particular model

Hi!

Note that I said it could "possibly" be a bad "head" (note singular).

Yes, if all the heads were bad or there was physical damage to any, then yes it would click.

Isopropyl alcohol (audio/video head cleaner) would be OK.
