And, an 18.4 GB (gross) SCSI drive will have about a 17.1 GB (net) capacity. The SCSI "read device characteristics" command return how many blocks the drive has. (A similar command does the same thing with EIDE/UATA drives). Drive Setup then determines how many blocks are left over after writing the required "system" partitions (this number varies with the version of Drive Setup, and could be six, seven, eight, or perhaps even nine), and the actual "user" partition or partitions start(s) at this block. The net usable capacity, in blocks, is the difference between the highest block number, as reported by "read device characteristics", and the first "user" block number. The net usable capacity is computed by dividing by the block size, which is usually 512. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
