Hello list,
Now i am working on recover some data from one defective drive. I am using dd_rescue, and dd, but both ready only 4K, i think, because the kernel's block size is 4K.
I have tried to google for the solution, but only found this trick:
losetup /dev/loop0 /dev/hdc blockdev --setbsz 512 /dev/hdc
and after this set, trying to read the hdc...
It looks like working on the first look, but not really. :-( The 512 size bad sectors still have 4K sizes, but the reading attempt takes more (8x ?) longer.
Somebody can help me to set the reading block size to 512 byte?
Thanks a lot, Janos Haar
