November 4th, 2015, 9:14
The info has been posted many times before. Not advisable if you want to recover data so think twice before executing it and don't forget to backup!

is this clear ng list
November 4th, 2015, 10:40
It's clear only G-List.
There is no command for clear NG-List.
November 4th, 2015, 11:09
I thought it should clear both lists? G and NRG or not?
November 4th, 2015, 14:44
If you have professional tools as PC3000 or MRT you can clear NRG list, but not via terminal commands.
Even HD Doctor (SalvationData) has the option to clear NRG

If you want to learn about what you can do in terminal I suggest you visit this thread:
https://www.data-medics.com/forum/seaga ... -t901.htmlAnd, yes I do believe that the T>i4,1,22 command clears the NRG. But, please correct me if I'm wrong... I don't do this type of thing manually much having PC-3000 here, so I very well could be off.

T>i4,1,22 is clear G-List only.
As far as i know there is no terminal command to clear NG-list. The only command that would come close is m0,6,2,,,,,22 this will clear both G-list and NG-list and rebuild translator taking P-List into account leaving user data area untouched.
First check if the NG-List has any entries using "V40" in terminal. If there are no entries its safe to use the above command but if there are entries make sure you BACKUP the drives firmware so you can restore the NG-List later or you will have very limited or no access to user data and the translator will be corrupt.
Trust me its not fun trying to rebuild a translator with a missing NG-list that had entries.

Also the i4,1,22 command DOES NOT delete the NRG, or P-LIST.
It deletes the G-LIST, ALT-LIST and SLIP lists.

m0,6,2,,,,,22 in some cases only Clear NGLIST and GList
but not Always
and other Command You enter For Clear Buffer is useless and Rarely if Success
you have 3 Ways for Clear NRG List
1- By ATA Directly less than 1 Sec
and in lettel cases may fail
2- By m0,6,2,,,,,22
50 % Success
3- Manually
by Edit Entries make it Zero
Zen Fill All Entries With Same data Pattern
and fill NRG Index
this 100 % Success Rate
and i prefer this way in all my work
i have video for this process if any one need PM Me
also i upload here
