According to the MRT-support I should

• Unlock firmware access
• Backup sysfiles 1B, 28, 35, 20D and 348
• Backup Module 3D
• Crerate a virtual start
• Clear the ALT-list
• Rebould the translator with the ALT-list

I just don't feel very comfortable doing that without really understanding what I do there...

Could someone please clerify what the virtual start really does and what options I need to tick. And what is the ALT-list? What could be the potential problems? Why do I need to backup the sysfiles 1B, 28, ... - just in case something goes wrong or do I need them later for something?

I have prepared all - I have the sysfiles and the module 3D saved ans well as the ROM. I just want to clearify all before I start.

I have solved it by waiting till the terminal was ready and then:

Code:

F"RWRecoveryFlags",00,22
F"BGMSFlags",00,22
F"PerformanceFlags",047C,22
F"MediaCacheControl",00,22

F"READ_SPARING_ENABLED",0,22
F"WRITE_SPARING_ENABLED",0,22
F"OFFLINE_SPARING_ENABLED",0,22
F"DAR_ENABLED",0,22
F"DISABLE_IDLE_ACTIVITY",1,22
F"BGMS_DISABLE_DATA_REFRESH",1,22
F"ABORT_PREFETCH",1,22
F"READ_LOOKAHEAD_DISABLED_ON_POWER_UP",1,22
F"READ_CACHING_DISABLED_ON_POWER_UP",1,22

F"SerialDebugLevel",1

... followed by Edit HDD ID to make sure the settings stick and I have not overlooked something.

Alt-List was filled up because head 3 was weak and produce in UDMA mode a lot of reading errors which cause the issue.

Head 0-2 are cloned now and I am getting head 03 to read in PIO mode. Actually I am filling in the gaps and hopefully head 3 will be holding up till I have cloned all. Actually I am getting out of head 3 aprox. 0.8 - 1.3 MB/s.
