Hi devs,
I''ve a serious problem with my 160 gb SSD which is not mountable
anymore. A backup for most of the date is there, but not for the latest
ones. :-(
The crash occurred during a download (system hangs totaly, hard reset)
with a Fedora 3.5.2 linux kernel. The btrfs partition was working quite
good for about one year.
here is a try to attach the device and mount manually:
