Questions about Seagate Drives and commands

December 20th, 2022, 17:40

I've just discovered the ability to interface with some drives with a terminal, and have been playing around with commands on a few seagate drives I have lying around at work.

My questions are:
I know what P-List and G-list are, but I was hoping someone could explain what the following are:

T-List
slip defect list
DOS (DOS config tables)
CAP
MC and MCMT

Also when running C>Q, I noticed these "Online" commands at the beginning:

Online CR: Rev 0011.0000, Flash, Abort
Online ESC: Rev 0011.0000, Flash, Abort Looping Command or Batch File
Online ' ': Rev 0001.0000, Flash, Pause Output
Online '.': Rev 0011.0000, Flash, Display Active Status
Online '?': Rev 0011.0000, Flash, Display Diagnostic Buffer Information
Online '`': Rev 0012.0001, Flash, Display Read/Write Statistics
Online '$': Rev 0012.0002, Flash, Display Read/Write Statistics By Zone
etc...

I don't see anyway to switch to "online" like you can with the other levels.
How would these commands be accessed?

those are available in any level in ASCII diag mode or in online mode.

Thank you, is online mode if you are connecting through SATA interface rather than ttl?

Online mode is when Sata intf is active AND it is possible to execute those commands.
Activated by ctrl-R, see the cmd descriptions.

Ah, I saw that, but misunderstood what it meant, and since it was under the 'online' command list didn't try it.

Thank you for the help.
