You should always start by backing up SA yourself ... No matter what tool do you use ...

On Toshiba P-List is CP DD and it's stored on Platter ...

SA = Service Area and stored firmware ...

2 experience

1) Sometimes drive goes endless busy when trying to adjust PList ,
2) Sometimes reading speed drop 10 Mb/s. Same drive normally reading speed around 100 MB/s at logic scan.

Sometimes long wait solve this problem. Sometimes press enter on any terminal window when connected Com port.

This is a new that I found. It's funny but working some times.
I removed data and power connection when busy. Pluged in a working toshiba. Lights turning on green. And removing good hdd. Again plug in busy drive. No power on of when doing this steps. Recall drive ID. Busy drives info come. Logout and re login toshiba part . MRT read busy drive Infos quickly and not in busy mode unless power of and on.
Funy but working

According to my research about Toshiba , busy mode occure some times about plist.
Plist record making endless busy mode.
I haven't try to find data recovery solution yet. But , if data not important busy mode could solve with deleting plist.
Sometimes some module corruption making busy mode. I saw mostly same modules bad
I would solve this issue for data recovery soon I guess. Principle easy for me now. But It's manual solution.


Also for wd drives busy mode sometimes about translator. (If solve slow repond command not solve busy mode )I had solve some cases with clear and rewrite translator. It's a lil dangerous . Sometime drive doesn't write back data and hdd gone. So firstly backup all modules , ldr and rom before operation. If drive collapse. Write original rom and all modules (By ID ) back. And drive returning back initial situation (necessary at least 1 primary head in good condition )

I have a toshiba drive . Trying to refurbished so has lots of bad sectors.
I tried firstly logic scan and add defects to plist. But lots of bad sector. And sometime increasing after add new defects.

After than , I deleted all p list and glist records and smart. Again logic scan
Very very little amount bad or slow sector now. Sometime I try to add new defects and again more bad sector.
I wonder why does drive behave like this.
I have meet same thing before. I couldn't understand what was happening before. Now recognised what is happening
I finished refurbish . Drive very good and so less defects in p list now. Maybe under 10 records.
If understand that behavior would be good for future lots of bad sector toshiba cases
