Unfortunately I am using extra.lzma (0.11) and hibernation does not work. I think I'm going to mount my disks at a linux distribution like this:
and do:
dd if=/dev/zero of=/dev/sda1
dd if=/dev/zero of=/dev/sdb1
dd if=/dev/zero of=/dev/sdc1
...
you'll get the idea.
Basically I going to wipe the DSM partition and make a clean install. This won't make you lose data (I already did this on the past) just all the configs... But anyhow, backing up data first shouldn't be a bad idea.
If anyone has a better approach, please let me know!
Thanks!
