MCMT table is corrupted


I red sys file only with terminal reading method.
I've a backup : 1b - 28_1 - 35 - 93 - 346
28_0 is corrupted (but I've copy 1)
348 is corrupted (both copy 0 and copy 1)
With SA LBA (with ignore read error) I extracted all 348_0 (7809k) (while with "file part" I can extract all except for first 4096 bytes )
In LOG I've :
SMP Dbl: 0x3C001000 - 0x0001FFFF (0x0000000F) (I think it's about 93 Parsing)
MC MCMT Ver is unavailable!!! (348 both corrupted)
no way I can write SA sys files. I tried with 93 after edit SMP (I left MCMT...and anyway the file was not written).
I tried with ...
ATA Indirect -> HDD Redynes timeout (10000)
Terminal -> Terminal: No response from receiver!

Hi, I have updates.
Working with a precise sequence and timing, I'm able to write sys file.
0-power (unlock tech...)
1-reading method -> terminal (460k)
2-read 3_93_0
3-edit SMP (disable all except MCT)
4-reading method->indirect
5-repower (unlock tech...)
6-right after unlock->write data to HDD

After SMP mod I wrote with same method 3_28_0 from healthy 3_28_1 (before I check Word sum = 0).
Now 3_28_0 can be read by terminal (460k) but not in ATA indirect or direct ... Why?
With ctrl x, XFR of 3_28_0 is ...
5859 7 27 02 011201 000000 1 00000080 XFR RD SYS LBA B 000000005783 L 0000000000ED BO 000000 BES 02A0C40.02BE63F.02A0C40
Error code is 00000080 so so it seems fixed

After I read 3_348_0 in SA LBA
terminal, text (115k) - Error recovery enabled - mode Maximum normal - Ignore read error
and it presents :
- 0x000000-0x000FFF with red background (in this range with other reading method I obtained DE AD)
- 0x000FFF-EOF looks healthy
- total length ->7B9000 sectors
- ctrl + a // MCMT PARSER
- with 348 ver 1 (I think that's the correct one)
Code:

Now I should repair timestamp, save modded file, use /CU10 command and write file to disk or upload file to RAM (would seem to be the preferred method).
But i don't feel confident in these steps as i'm not sure if my utility version (6.6.29 7164) is up to date enough.
Can you help me please?
