I've tried "DF4 Complete Original ARCO Script" on the worst (bad head 0) drive. It ended after 45 minutes with BG_PST_UNABLE_TO_LOAD_PTM error. Now the drive does not work at all. The model name is empty. When I load overlays from modules backed up, the name changes to ROM ID. But it's not able to initialize directory so the modules cannot be restored.
First write back ROM, then restart drive.
Now 'Emulate SA Translator (ROYL)' and 'Restart FW and block loading FW', load overlays->'yes'
Write back all modules and restart drive
If dir can't be initialized, use 'Write and initialize dir', load overlays->'yes'
Then restart, 'Emulate SA Translator (ROYL)' and 'Restart FW and block loading FW', load overlays->'yes'
Write back all modules and restart drive
If self scan and arco fails, just cut the bad heads and change them to 1.5TB drives.
Weak heads on these drives are sometimes hard to detect, because they work good when the drive is warm.
Do a write test for some minutes when the drive is cold. If a head is weak, it will write garbage. With a read test afterwards check if all written sectors are readable.
Or look in G-List, which heads have most reallocations.
