a ja hovorim, ze mi to robi aj na UPLNE CISTEJ A NOVEJ PASKE, cerstvo rozbalenej
. (na dvoch novych cerstvo rozbalenych) prave preto by som to, ze je na paske
nieco o com neviem s takmer 100% pravdepodobnostou vylucil.

a pri tychto pokusoch som si v logoch nasiel este aj toto:

st0: Error with sense data: Current st0: sense key Aborted Command

 Key=Bh (ABORTED COMMAND); FRU=00h
