I should add that the above is for ATA drives. For SCSI-class drives
the standard applies to 2.5" drives over 73GB and 3.5" drives over
450GB.
I did the maths for some common capacities:
Capacity (GB) LBA count (512-byte blocks)
250 488397168
500 976773168
750 1465149168
1000 1953525168
1500 2930277168
2000 3907029168
