- Flash type: USB
- Controller name: U20TWGOD / 0528 / D1T8W-010GTFI
- Flash chips amount : 512MB
- Flash chip name : Toshiba TC58NVG2D4BTG00
- Config file content (Show config) : TC58NVG2.cfg
- Dumps amount : 512MB
- Do you found FAT? yes
- Is there mix? yes
- Do you remove mix? yes, split by block 0x42000 + join by block 2112

Put piece of FAT on FTP: yes,
file name: "hd07-300k.dump" ------ before solving mix
"hd07-300k-join.dump" ----- after solving mix

I tried the uitl 1001, with
block size = 0x84000, marker: 514/515
The results is ""find bank space: fail"

Which util should I use?

Thanks.

Wrong.
Do you check it after join?

Code:
Now you have: 00 01 02   FF FF FF FF   07 08 09 0A   FF FF FF FF   0F 10 ...

You need:     00 01 02   03 04 05 06   07 08 09 0A   0B 0C 0D 0E   0F 10 ...



Return to starting dump and resolve mix.
Check result after.

Hi,
Thanks for your reply.
Yes, I did see them as I even verified the block size.

Now I redid the split and join. The result is the same.

I re-read the memory 3 times, all have diff when verifying:
For 1st read,
diff: 013da000
diff: 10b7b000
For 2nd read,
diff: 10b7b000
diff: 122af000
For 3rd read,
diff: 013da000
diff: 10b7b000
diff: 122af000

Does it mean the memory chip has some kind of problems?

Thanks again.
Phil

No
This mean wrong convertion operations.

First find, then think, then split & join.

You need find missing: 03 04 05 06
Then think how to put them back.
Then use Dump_Converter.
Then check.
If wrong repeat steps.

Yes, it works after I used "split by dump 2".
Thanks again.
