Help with Hitachi HDT725032VLAT80

[triharp]

Hi Friends,
I've got a defective Hitachi HDT725032VLAT80.
The drive is starting, but stays busy, while the heads make small clicking noises. Not a hard click as when a head is broken, but small clicks as it is recalibrating.

I had an exact donor and so I try:

- Swapped pcb: go to ready but I can't access to SA. I can't use "Dynamic Repair" on SalvationData HD Doctor.
- Changed nvram on the pcb: stays busy
- Changed HEAD: stays busy and the same small clicking.

Anyone has a suggestion to get it working ?

Thanks in advanced,
Leonardo.

First of all, a precise diagnose is needed.
For this, you should have tools and not only toys, and knowledge.

I can recover this drive, but not remotely.

PM me if interested.

Here are some suggestions:

Never buy or use any Hitachi hard drive in your life, why?

Here's why:

1. Then are manufactured poorly, and do tend to break when you least expect them to.

2. I recently was using a Hitachi hard drive, then right after I backed up my most important data, the hard drive started clicking. I was "extremely" lucky just 10 minutes or so before the hard drive completely died.

3. I do not know wheither you may or may not know this, but I am sure other hard drive manufacturing companies do not do manufacture hard drives with such specifications as the one I am about to mention below:

After the laptop hard drive went dead, I played with it some, then opened it up and saw that the problem was with the read/write heads. Then after I plugged in the hard drive through the laptop external case, while it was open, I used a small screw driver to make sure no data could ever be recovered (I made many lines in many circles - NOTE: Do Not Attempt to do the same. Why? Here's why:).

So later on, this is what I discovered: Then I took the disk inside the hard drive off with a torx screwdrive, and tried to bent the disk over the trash can, and all of a sudden "snap" the disk broke. And it was actually "made out of glass" and not metal, like other companies do so.

I "never expected" anything like this. Because this is a very cheap was to manufacture hard drives, which in-case of serious data loss, is like having your data on a piece of paper, which is guaranteed un-recoverable (i.e. example: you drop the laptop hard drive from big height and the disk glass breaks - which "is the actual disk inside the hard drive").

So I would never ever again use any Hitachi hard drives, just in-case my data does not become "nothing".

Note: These are just my suggestions, and they differ from one person to another person. Therefore, please do not take them seriously.

Thank you very much.
