Toshiba 61GSY: which module is the Glist ?

[PAKcomputers]

I have a toshiba 61GSY that has glist issues

trying to clear the glist in pc3k fails with
G-List reset error : Device Error Detected 51/1C (ABR;<bit3>;INF)

which module is the glist in ?
can I write a new one from another drive, then clear it ?

G-List cannot be read the same way as other modules. It can only be:
1. Read by a special command, specifically created to read G-List
2. Cleared by a special command specifically created to clear G-List
3. R/W using PCHS access as a group of physical sectors (not sure if such functionality exists in PC3K for this model)
