Struggling with this one, did the last UP10 controller OK.

2 Dumps (only one bank found in each chip)

Find FAT16 in 1st dump @ 0x179f4000
Find 00 ...02 ...04 ...06... in FAT of 1st dump, in consecutive sectors

Find 01 ...03 ...05 ... 07 in same place in 2nd dump, consecutive again

So, I think join by 528, right?

Block size I find to be 0x108000

Use Block Number 1001 with Marker 514/515 and get..

Show Blocks
-----------
Bank 00
0x0000 - 0x03f3 = 1012
Bank 01
0x0000 - 0x03bb = 956
Bank 02
0x0000 - 0x0000 = 1 <<< look here
0x029e - 0x029e = 1

Find Bank Space
---------------
Bank 01 Start 0x03ff Size 0x3ff -> 0x400 OK

Find Bank Size
--------------
00 / 0x000 / 0x3f3
01 / 0x000 / 0x3bb


Make disk.image, but not folders/data Sad

I'm going to try and upload the 1.dump and 2.dump to the container, see if you can tell me where I've gone wrong.

Thanks

MBR, FAT, FAT1, FAT2 green or red?

Root on place?

MBR and FAT are green, but folders are complete garbage.

Raw scan find nothing good, some headers but no real data. Sad

I will do that tomorrow, I'm at home right now.

I did think that Bank 2 looked wrong, but could work out how to get it right?

Although this is a 2Gb drive, there appears to be very little data.

In fact, both 1Gb dumps were able to be RAR'd and put into the container. Wink
