hi Again Sergei ..

I'm haveing a bad day Sad

I have just uploaded 300k from FAT32 table to ftp.

I cant work out the block numbering of this chip, apart from 42000h block size.

Any ideas ?

I have two identical chips for recovery, so if you need the second one, let me know.

Do you see 4 last bytes in sector.

One of them is block number.

Its time for you to learn Virtual_Translator :)

Thanks for the hint Sergei ..

Using these lines:

ea 00 ff 00 ff
ea 01 fe 00 ff
2a 02 fd 00 ff
ea 03 fc 00 ff
ea 04 fb 00 ff
2a 05 fa 00 ff

I can see the block number (00,01 ..05)

First byte is either 2a, 6a, aa or ea

Now I'm stuck - I need to get them in some sort of order, but dont know which module to use ..


Before I use VT I need to get them in close block order ..

Hi Segei,

I had already tried those combinations Sad

When using those parameters, I lose the boot sectors and partitions - scan for jpg results with 70 corrupt images.

Other methods I have tried is raw and scan for photos, this gave 200 photo's but all were corrupt.

I'm wondering if the Block numbering system is XOR'd with something ?
