Toshiba 3.5 DT01ACA200 - Busy state

[RCCU-Brussels]

Hello,

We tried to access to the datas of a Toshiba DT01ACA200. The state is always "Busy" and it's clicking.

We noticed that the heads left the "Park zone" to the center non stop, the surface area don't seem accessible.

Here is a capture of the voltage

We removed the PCB from the hard drive and we choosed the profile "7210DLE6" (we saw on Internet that this profile correspond to a Toshiba DT01ACA200) and we have this error :

Code: Select all

Selected family......................... : 7210DLE6

We also tried the profile "MG03ACA" from Toshiba but we have this error :

Code: Select all

We have a donor hard drive but we think it's a logical problem

EDIT:

We also follow the steps from this article https://blog.acelab.eu.com/2045.html :
What about drives which are get a BSY state without Drive ID and capacity?
Maybe problem called by damaging G-list or SMART.

Try to perform the next steps for Service Area access:

1. Turn off the power supply and isolate Heads contacts on PCB.
2. Turn on the power supply. Now disk BUSY.
3. Perform Soft reset (F7), if it doesn’t help then perform Hard reset (F8).
4. Now drive get a ready state. Then perform Sleep (Standby) comamnd. Go to “Tools” -> “HDD” -> “Standby”

=> We have always a busy state with the isolation of heads contacts

RCCU-Brussels, regarding your description it's not a logical problem. I'm more than sure it's a heads failure.
Actually this drive isn't a Toshiba so all actions you did from the article for diagnowstic won't work here.
Good luck with heads swap!
