thanks for the reply...

its been 5 days.
this is data recovery.
Its time sensitive.
The customer needs an answer
do you guys have a solution for this problem - yes or no ?

glist is bad
erase glist does not return an error
but glist is still corrupt.

and yes i can read the zone table to the mpu is working...

roustam suggested that I swap heads.
I did.
Then it erased the glist!
hooray
imaging now
head 0 is slow

thanks

I recently had one of these Toshibas with glist error that would not let me clear it out. It gave errors when trying to clear. The CPs were all good- so I backed them up.

I got a donor and backed up resources from donor (ROM, CPs, etc). Be careful to put donor's resources in different folder than customer's.

I moved customer's ROM to donor PCB. In Toshiba utility, I then was able to clear G-list and SMART.

I then repowered and moved customer's CPs back to customer drive (keeping the donor PCB with customer's ROM attached to customer drive).

I was then able to read all the data.

MKS please can you explain what you've done precisely, it seems some steps are missing ?

[AJ2008]

He moves ROM to donor PCB and clears GLIST there

GLIST stored in PCB not SA

Ok thanks.
In my case, my tests have killed heads...
I can see now many microscopic scratches on one surface (when I got it heads were on the platters and prevent motor from starting).

Can you tell me how to move rom in Toshiba utility ? i cant see in mine Pc3k i really appreciate

This moving of ROM refers to transfer of physical ROM chip with rework station
