To mi teda nekdo vysvetlete --- to jako do mainframu se montuji specialni disky s takhle divne vetsim sektorem, nebo ten server normalni SCSI disky nuti aby mu vraceli sektor i s nejakym ECCckem nebo CRCckem, ktery si na PC pocita ten disk sam pro sebe a neobtezuje s tim CPU?

Mozno teraz hovorim uplne z cesty, ale mainframe svet pouziva 520B bloky nie 512B. Tyka sa to diskov. neviem, ci CD/DVD nie je nejako emulovane...
