Western Digital 120Gb drive
I went to L0wYat on Tuesday after work. My purpose is just buying a new hard disk (notebook type), which currently the largest and best price is 120Gb. It cost me RM370 including the 2’5 casing. Cheap bo..I get this price for 60Gb more than a year ago.
He (Adam) went with me because he wanted to get 320Gb PC hard disk. He used up 99%, thanks to me haha…all my series drama bomb up his capacity. I already told him to invest a DVD writer but he resisted. Haih.
The following day, we talk about the ‘lost’ space. We both argue the reason behind the ‘lost’ disk space. I am strongly confirm that the ‘lost’ space is cause by the space calculation based on the drive manufacturers.
The reason why 320Gb drive show up as 290Gb because:
1MB = 1,024 kilobytes = 2 power of 10 (2^10) = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
1GB = 1,073,741,824 bytes = 2^30
So, everyone uses 2^30 as a real space for each gigabytes.
Actually drive manufacturers use 1,000,000,000 bytes = 1 Gb.
That’s mean we lost approximate 73Mb for each 1Gb in above case.
And 320gb (real space), show only (320 – 23.36 = 296.64Gb)
The BIOS may detected your new disk as 80Gb or something, but if your XP can read your disk space correctly, then it should be fine. Right? Sigh…we argue for nothing.
