Problem s SSD pod linuxem

[Pavel Kutina]

Tak po prebootovani do nejakeho normalnejsiho live distra je dmesg hlaska o 
read only systemu (:

EXT4-fs (sda2): INFO: recovery required on readonly filesystem
EXT4-fs (sda2): write access will be enabled during recovery
EXT4-fs (sda2): orphan cleanup on readonly fs
EXT4-fs (sda2): 3 orphan inodes deleted
EXT4-fs (sda2): recovery complete
EXT4-fs (sda2): mounted filesystem with ordered data mode Opts: (null)

cislo partition je spravne, v mount se ovsem nevyskytuje ani jako ro

jinak pak uy jedina opakujici se hlaska je

sda: sda1 sda2 sda3

po hdparm info pise v sekci Security, ze supported, not enabled, not locked, 
frozen (co to je???), not expired
