Toshiba MQ01ABD100 failure

[ssbbidask]

Hello, I have a 1 TB Toshiba 2 1/2 inch hard drive. Drive suddenly stopped being recognized by laptop showing "no media found "at boot. Suspect PCB failure. I bought matching PCB where firmware chip not transferred. Drive installed as external with old PCB with same result. Yet, I can hear drive spinning with no noise. Tried installing new PCB. Now I hear drive spinning with clicking noise. Installed new PCB without swapping firmware.
Two questions: would PCB swap cause any damage Without swapping firmware chip? Should I swap firmware ROM and try again?

Was drive spinning with original PCB? If not, can you upload a photo of the PCB?

I'm working on a similar model right now (MQ01ABD075) with heads that are starting to crash. I can't say that I've seen many with PCB issues.

Yes the original PCB installed the drive platters were spinning with no noise or clicking etc. It was only when I installed the new PCB where I heard the clicking. Here is the original PCB.

It is not a PCB issue and should be diagnosed by a data recovery pro with the necessary equipment.

Agree, nothing to do with the PCB.

Probably a g-list issue.
