[Tomas Lukala]

Ahojte,

mam "radostnu" otazku: ako je to s podporou velkych diskov v Linuxe? Vsade
citam, ze pre ext2 ak je velkost bloku 4kB (co je tusim default) tak max
velkost disku je 16TB. Moj disk 3TB pripojeny cez USB<->SATA konvertor
hlasi po pripojeni USB konvertoru:

co mi evokuje, ze problem bude skor v tom USB<->SATA konvertore, nie som si
vsak isty. Pripojit disk priamo na SATA konektor nemam ako - nemam po ruke
nejaky comp kde by to slo a do svojho laptopu ho nemam ako pripojit.
Pouzivam
Slax 6.1.2, jadro tam je 2.6.27.27, fs ktory chcem na disku vytvorit je
ext2.

Stretol ste sa niekto s niecim podobnym? Alebo som urobil chybu ked som
kupil 3TB disk?
