Hi, As I like experimenting with file systems, and as lots of boot cds don't have the latest kernel/userspace tools, I decided to create my own bootcd for my personal use. As I think it could be interesting for other people, I made it available at http://prrescue.prnet.org Bye, David Arendt

. Maybe this is pure coincidence and has nothing to do with the fact that it is on SSD or HDD. Another thing I noticed is that for me, the problem only seems to occur for root subvolumes with many small files. I have no root subvolumes on HDD so it might be not SSD related.
