Trochu moc nul najednou. Takhle by to melo vypadat, kdyz v mechanice neni 
paska (a ne kdyz tam je).

Zda se, ze se nepodarilo vubec nic zapsat.

Zase chovani, jako kdyby nemel zadnou pasku.

Key=B tedy "aborted command" podle SPC znamena, ze se prikaz rozhodlo o
sve vuli stornovat cilove zarizeni. ASC/ASCQ 4B/00 je "data phase error"  
bez blizsi specifikace (to jsme ale najednou chytrejsi...<g>).

Celkove mi to pripada tak, jako by mechanika nebrala vlozenou pasku na 
vedomi.
