Hi.

I am working about fixing bad Toshiba drives (refurbish) for a while. I have lots of Toshiba drives.

Firstly every brand have different designs for p list and g list
P list = Primary Defect list.
G list = Grown Defect list
PBA = Physical Block Adress
LBA = Logical Block Adress.

Drives has millions of sectors . And so much blocks.

P list use PBA
G list use LBA
Logic scan report LBA
Cut head function just add heads PBA to P list which head wants to cut.
Cut zone use PBA

I have so much problem when I trying to add new defect to Plist or G list.

PBA never change. It's always fix so it's physical address.

LBA logical. LBA changing after every attempt listed below.
Cut head》》 LBA changing
Add new defect entry to plist , or after cut zone, or cut /shield head》LBA changing.

If you made wrong action . Some times drives would not recognised on MRT after that attempt. Lots of articles says don't touch to play list . Also MRT technician told më same. But I have made so much modification to Toshiba drive P list, G list entries. Deleted. Revrited. Cutted zones , shielded heads, every scenario that I can imagine I guess. Some modifications making drives unrecognized on MRT also. )) but. ..
I have fixed all drives again . I don't worry about work with Plist Glist on Toshiba drives now.

There is a big problem about Plist using PBA but , logic scan report just /only LBA . Remember, LBA changing after every modification over P list.
There is a manuel add defect option in Plist editor page. Also there is import CHS or LBA file option.But it's not calculate true value. I have experienced maybe 20-30 drives, and maybe experienced 5-10 times for each drive .
I couldn't find solution to use Logic scan report of LBA list or LBA file to add p list.
Everytime changing LBA mixing everything.

Cut head working perfect. But there is no option to demount this head. Remember . Cut head adjust P list . But , if you haven't back up p list before cut head, p list would clear firstly when cut head . It's making trouble sometime. People says don't touch p list. But when I try to cut a head it's directly deleting p list. !!!! If cut head operation has error or interrupted so there is a nightmare. Sometimes MRT wouldn't recognize again that drive But there is a only one solution. Wait till busy turn of and green lights on. It's taking so long time. Sometimes 10 min to 30 or more.just wait. And try to delete or rewrite p list backup.
My best solution 》using cut zone option, selecting only 1 entry, and apply.


I will post some more details .

If you have something like SeDiv you can run a victoria scan and select what you want to log on victoria (access time) then use that log on SeDiv to cut zones with slow access sectors or entire heads, etc .... You apply, it saves to DD and you are done....

When you get that BSY drives try to press enter on terminal ....

For Toshiba, busy drives doesn't make problem with MRT. It's working nice . I like Toshiba drives don't make me trouble so much. And MRT fine for Toshiba. At least for me till now.
My problem only about defect list that I wrote . I found manuel solution after write that post to regeneration P list. But it's manuel method and taking so much time .
I repaired more Toshiba has busy or very very bad condition . They are working perfect now. No slow sector. No bad sector . % 100 health in hdd sentinel.
I don't have sediv. Maybe in future.

I did get one MRT Ultra card today (on-line) and i will activate it tomorrow (it's late now and i do have to install windows on the MRT machine). I will have lots of fund with it on the weekend because i will be out-of-work playing with it all day !!!

The only thing that it will be "new" to me and that i'm very curiouse to try is the SSD experimental tools as apart from "cloning" or "imaging" as standard ATA devices i did never saw or play with SSD firmware. I think i will have lots of fun with this.

Nice to read this from you :)
I know you like to test tools, i will like to read your opinion on mrt (new version has been released today).
Read change log:
http://us.mrtlab.com/download/uplist.htm

They haven't updated anything for SSD in last release, many SSD are not supported yet!
