Toshiba MK 4025 GAS

[usedgomac]

Hi to everybody,

I need a helful information, in order to recover information of my hdd death. The bios system doesn't recognize the disk. The disk only makes a head noises crec-crec-crec, several times (4 o 5) and then stop. It seems that the hard disc don't rotate.

I tryied with a live cd with recovery programs, like Salvation HDD and MHDD32, etc, with any success.

MHDD32: When I send a reset to the hard drive, it tries to move the heads, and the programs replay a timeout.
IBM/Hitachi Feature tool 1.97: It detects the IDE primary master and the type of disk, before the crec-crec-crec sounds:

I bought two new disks with the same description

MK 4025 GAS HDD2190 B ZE01 S, same cilinders, etc., in order to change the PBC, and if i've luck, recover the information. I'm thinking also changing the plate to one of the new ones.

Do you have any other suggestions?

Thank you very much.

Who did you suggest to do that ?

It's very very unlikely to be the PCB, and even if it was you can't just change it. The PCB contains unique info, even down to the serial number.

If it's making a "buzz-buzz-buzz" noise and the platter doesn't spin, it'll almost certainly be the heads stuck to the platter (stiction).

At this stage a pro recovery should be pretty reasonable, but if you do try to fiddle with it you'll almost certainly make it much more expensive if not impossible.

I've seen a lot of motor problems with these drives. Final answer is to take it to a pro if you want your data back. Otherwise swap any part you want its not going to make a difference in getting your data.

Bearing failure with heads parked on the platters is the most common failure mode (for this model) in my experience.

I hasn't change the PBC, it's only and idea.

Then, the problem is a hardware problem, I can't "reset" the drive, that's ok? You suggest sending to a professional, but I can't do anything to repair it (I've to new ones)?

Thank you for your pacience

Hi,

If you need the data then please consult a pro, it shouldn't be too expensive from the right guys, as this is common problem and straightforward to a pro.

You're right, it is a physical problem and there is nothing you can do yourself. Well not unless you have plenty of experience in these drives, the right tools and a cleanroom.

"dmarques" is possibly your nearest recommended pro, in Portugal. Or I am in UK.

Good luck

ok, thank you, I'll try to RecoveryLabs in Spain, told you how does it works

[pcimage]

Hope it goes well for you, it should do as it's a easy job for any pro.

Good luck!

Hi to everybody,

Before sending to a pro, i tried to change the PBC from a new one. Previously, I've work with the new one with no problems.

When I change the new PCB to the old hard disk, the hard disk did the same (rrr-rrr-rrr)

When I change the old PCB to the new hard disk, the hard disk has been broken, now it sound like the old one (rrr-rrr-rrr)

Seems to be another faulty, not physical, but logical.

Is any software to access to the PCB and check it? Can I "reboot" the PCB?

Thank you for your patience...

When the spindle becomes stuck/ heads stuck to platters it puts extra stress on the spindle driver on the PCB. This can burn it out and kill the PCB. This is likely why the PCB from your old drive does not work on the new drive even if the new drive has OK spindle.

Can I update the spindle driver of the PBC? It is recognised by hddscan in a usb port?

Spindle driver is a hardware chip.
Additionally, you can't update nothing through USB, except the user area datas.

ps: my saying: The definition of the hardware: what we can kick.

[Russwinters]

Indeed, spindle driver is not a driver as in graphics card drivers, etc. It is a chip on the pcb, that overheats/dies when put under too much stress (from the spindle being stuck, unable to move ,etc)

sometimes it can work the other way around, where the spindle driver dies and this is why the spindle does not spin, but not in this case.

Maybe he means driver as a "car driver"....
