Problema si ostana nerazreshen, no za sega mi si mahna ot glawata (t.e. ot 
glawata na kolegata).
Netstata si gi predstawqh gore-dolu po systiq nachin kakto gi opisa Boyan, i 
kakto wsichki drugi, samo che ne stanaha taka.
Imam na edna mashina takyv RAID (CMD 649), no tam raboti kato obiknowenno IDE.

Nakratko problema maj se dylvi ili na towa che platkata ne e 100% hardware 
RAID ili na drivera za neq (i dwete mi platki bqha sys "Silicon Image" chip).
Pri pyrwa wyzmovnost ste probwam otnowo i ako ima rezultat ste postna w 
grupata.
