Hi everyone. I am having trouble data extracting with PC3000 of Samsung ST1000LM024 HN-M101MBB

The drive came to me knocking- I already change 1 set of heads. H1,H2,H3 all mapped good except for H0
- Drives was mapping smoothly until it reaches a bad sector. The drive keeps hanging and BSY upon trying to save bad sector into G-List
- If i put DE to map it will hang. However pressing and holding next to read sector by sector the drive runs smoothly
Can anyone guide me to disable G-List so the drives stops hanging???
Many Thanks!

I don't think you can -or at least I don't know how. If you find a way please post it, I have a ST1000LM025 doing the same after taking 5 sets of heads to read, and I just need 4GB more from it.

The most stable settings I could find in DE are block size 1, UDMA-33, Timeouts ( 15K,500,8K,2K,10K), Soft, Hard and Power. This gives plenty of time for the drive to do it's business after a failed read and repowers if it runs on too long. You might also want to check/clean the platter surface/ heads. You might also want to look at mapping by head chain and jumping to the next after 1 or 2 errors.

I think we can disable it through terminal and SA modules. But yeah. I still have no clue how

For what it's worth. USB stablizer also handles hardware resets better with the original pcb on mine than using a sata board.

If you can upload the full terminal log, that might tell us which SA modules are loaded during start-up. One of those might have the relevant configuration parameter(s).
