Toshiba MQ01ABD100H G3461A PCB Dead

[Contract_Pilot]

Hello,

I have a Toshiba MQ01ABD100H drive that one day was dead no spin nothing will not even detect in the bios... I removed and put in a USB dock nothing no noise etc. Data on the drive is not to important figured I would post here maybe get a place to start to see if it can be salvaged vs. going to the landfill after a visit from the air hammer.

Nothing visually on the board looks burnt, But I am capable of minor smt surgery if required replacing diode, resistors, etc.

Thanks in advance.

I would start by measuring the voltages at the fuse and V1-V4.

I would also like to know the markings on each of the chips, if you can make them out. IC617 is of special interest to me.

Thank For The Reply fzabkar

5V Line is 5V
Fuse is 5V Both Sides

V1 is 2.9
V2 is 2.5

V3 is 1V
V4 is 1.7V

I noticed on the drive where PJ701 connects to the drive that there was oxidization on the pads on the drive.

Gave it some cleaning re assembled it guess what... it spun up and it detected. but no partitions

What device was the drive out of?

A laptop or a USB caddy?

Maybe it’s passworded or encrypted?

Was out of a laptop.

It is being detected now quiet no clicking or anything but shows no partition and cannot be partitioned tried all I can just get i/o error trying to initialize it.

Have you still got the laptop?

Did it ask for a password on bootup?

If so then put it back in the laptop and enter the password.

There’s no chance you could have mixed up the PCB for a other one?

[Contract_Pilot]

No password on boot up in the laptop. I will try some other tests that have been recommended.

It is hybrid drive. Behaivour very similar when problem with NAND. Need to init it using special technical commands via terminal.
