I am trying to recover an old hard disk IDE. Maxtor DiamondMax plus 8 40 GB
The owner unplugged the power source and then fault.
Someone tried to do something on the disk. But we don't know what...
I suspected damage on the PCB, so I bought the same disk and swapped the PCB.
First time In power on it. The disk did two/three beeps and moved the disk.
I see the disk on device magaer, but with no partition. I expect FAT32 or NTFS
What is possible to do?
thanks

Does the patient's PCB work on the donor HDD?

Does the patient drive identify itself with the correct model number and capacity?

Can you retrieve its SMART report?

Can you see the contents of sector 0 with a disc editor (eg DMDE freeware)?

using hddscan I see the disk as maxtor N40P firmware 3g4z. But I can't click on the smart button.
using Crystaldiskinfo I can't analyze the disk.

Sounds like a firmware failure. Overflowed G-list probably.

Hi, I tested HDDscan 3.3 with both PCB, but no SMART report.
On device manager, you can find:"disck 1, unknown not inizialized"
Try to do carving?
thanks

My guess is that the drive is suffering from a firmware problem as already mentioned.
It requires special tools and knowledge to fix, assuming the heads, spindle, etc are working and the problem is indeed just a typical firmware issue.
If you need the data from the drive seek assistence from a data recovery pro.


OK thanks all. Where is located the firmware? Not in the PCB I swapped?
bye

The firmware is in a reserved area on the platters.

See viewtopic.php?f=16&t=6562

I suggest you consider outsourcing this drive to forum member BlackST who is also located in Italy.

Thanks again for all answer. I will send the disk to an experienced structure. But I would like to know which is the best way to become a Jedi in disk recovery. Someone asked me 5000 euro (6700 $ USA) for five days training... I am not sure that worth!
thanks

Besides the training, you will need to buy special tools (around 10-40K dlls) and at least 2 or 3 years of practice, and after that time you may know "some" about the DR business. Honestly, the only training is nos enough.
