The mybook live uses a really wierd blocksize when setting up the partitions:
mkfs.ext4 -b 65536 -m 0 /dev/sda4
When i bricked the device for the first time i tried to connect it to my computer to save the data. I could not get it to work since the largest allowed blocksize is 64k so the host OS refused to mount it.
Now… I don't wanna end up in the same situation again. If the mybook for some reason whatsover dies for real. To that end i tried running:
mkfs.ext4 -m 0 /dev/sda4
in order to get it to run using a regular blocksize. it worked fine from a host system to mount it.
but when i try to mount it in the mybook:
mount -t ext4 /dev/sda4 /DataVolume
mybook answers that "mount: File too large".
This leads me to the conclusion that the Mybook uses that wierd blocksize in order to use the large hdd.
Soo… Anyone managed to fix the blocksize in the mybook live or managed to mount the data partition sda4 in a host system?
