Read G-List ?

[SuperDuck]

Hi guys,

Is it possible to read the G-List entries on a Seagate sata drive, using the standard data connection, without using the service connection? I think it would be logical as it just reads an important info, which wouldn't hurt to be exposed to non-technical people and pc software.

I've already backed the partition up, with 11 unreadable sectors, but SMART reports 12, so I just want to see the list. And on another drive I recently got 1 reported by SMART. It could also help me check this one and any future disks without reading the whole disk and long wait times resulting from bad sectors.

Thank you!

hmm I've found 'read defect data' SCSI command for SCSI disks. I wonder if it will work or has a relevant for SATA disks, esp when considering some software see SATA disks as SCSI.

update: I've read somewhere the command hasn't been mapped to SATA disks, and you can't see defect lists on SATA. well, I hope it doesn't apply for all SATA disks, but I guess this is the end of story now.

I've tried once the V command on Seagate Barracuda SATA drive 7200.12 and it worked.
In Level T:
V1 = View records of P-List
V2 = View records of Defect List of SA
V4 = View records of G-List

I hope it would help!

Yes, for DIY you need RS232-TTL converter connected to the jumper block in order to execute terminal command.
