An interesting 3409AH-E : 500-c3c5

On the first run all modules in HDA report good - MPG3xxxAH.

01h, 03h, 0Ch, 0Dh, 2Dh, 31h and 32h not loaded correctly to RAM.

09h reports correct in HDA and RAM.

ROM recording shows corrupted. mmmmm what to do ??

took 800-c3c5 ROM file and created donor.
On spin up with donor the drive knocks.


returned original pcb to HDA and drive works perfectly.

No modules were written to SA at any time.

On examination of modules recorded from first run and working run
found only 09h was different.

module 09h varied in the following hex offsets :

7h, 8h, 2Bh, 43h, 44h, 5Bh, 5Ch,
73h, 7Fh, 1F8h, 1F9h, 1FAh, 1FFh.

self repairing SMART ? or just luck with CL ?

Note : 09h loaded to RAM on first run was corrupted but reported as correct


btw. any1 have rom and mods for :

Compaq MPG 3204-AH (with 4 heads)

F/W : 600-D290 and also 420-5207
