Re: how to rescue this backup data

Hi,

it comes to me that 1256091 is not a probable
exact start address. It should at least be
divisible by 16.

A multi-session DVD+R by xorriso looks like:

TOC layout   : Idx ,  sbsector ,       Size , Volume Id
ISO session  :   1 ,         0 ,    739194s , UPDATE_HOME_2008_06_22_191945
ISO session  :   2 ,    741392 ,     20333s , UPDATE_HOME_2008_06_25_190436

ISO session  :  49 ,   2201056 ,     46953s , UPDATE_HOME_2008_11_30_201431
ISO session  :  50 ,   2250208 ,     32503s , UPDATE_HOME_2008_12_04_190853

(Note that 741392 is not divisible by 32.)


Well, check what is written in the first
sessions. Hopefully this will yield a better
number than 28. 0x17 = 23 would be nice.


Have a nice day :)
