Re: PCB board

Send it to the Toshiba tech service for repair. But that might be more expensive than buying a new one.

Why did you disassemble the device?

Data recovery specialist may help

Hi @Khaledelazhry!

I agree with what the others said about the repair, but if the data stored on the drive is important I would suggest to contact a data recovery specialist and see if the information can be extracted.

The danger with changing the PCB is that it may have different settings for how to align the heads to the tracks on the physical disk surface, and when it tries to write anything (which it will) this will result in all your data being obliterated.

However, if you decide to try it go ahead, but I won't recommend it. I'm not saying that not only because this is an unsupported and not recommended operation in general, but mostly because that the risk of damaging the drive further is too big and that the chance of finding an exact match of a PCB is really low due to the differences in firmware over the years.

Hope this helps and feel free to ask any questions you may have.

Cheers! Happy

Advice from a Data Recovery Professional

I actually work in data recovery (https://www.data-medics.com) and I have to say you are in trouble. Toshiba drives are different from other brands. Most HDDs store the drive specific info primarily on the platters in a hidden area called the service area. Toshiba however uses configuration pages which are stored entirely on the ROM which is on the PCB. Even a data recovery company won't be able to help unless you can find the original PCB. It's not like other brands such as WD where you can simply rebuild the ROM in most cases.

You really should try to find it.
