Zkusil jsem a dela to pri grabovani tak 70-85% takze aspon zatim se neseka
celej system. Ale neni to jen tim -u1, proste celkove nastaveni.

/dev/cdrom:
 HDIO_GET_MULTCOUNT failed: Invalid argument
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  1 (on)
 readahead    =  8 (on)
 HDIO_GETGEO failed: Invalid argument

Mam nastavit to -u1 u u HDD? Nebo to neni vhodne? (v manu jsou i warningy
pri zapnuti -u1 tak nevim)
