[理工] [os]-磁碟
An IDE hard disk spins at 7200RPM,1000 cylinders,10 tracks per cyclinder
100 sector per track, and 512 bytes per sector. The disk is performatted
by a file system which the logical block size is 1024 bytes. If we ignore
the space to keep directory and indexes, how many 1-byte files that the disk
can store ?
Disk總容量為512000000 bytes，為啥還要除1024?不是直接除5120000000/1byte就好了嗎
