i bought an 80gb seagate barracuda hdd yesterday and installed it

But it is only reading 74gb of active space ..

Is this a normal percentage of the drive to lose to pre -formatting

???

thanks

1 Byte = 8 Bit
1 Kilobyte = 1024 Bytes
1 Megabyte = 1048576 Bytes
1 Gigabyte = 1073741824 Bytes

so...80 GB : 1048576 = 76.2 Gigabyte.

Kilo K 2^10 = 1,024
Mega M 2^20 = 1,048,576
Giga G 2^30 = 1,073,741,824
Tera T 2^40 = 1,099,511,627,776
Peta P 2^50 = 1,125,899,906,842,624
Exa E 2^60 = 1,152,921,504,606,846,976
Zetta Z 2^70 = 1,180,591,620,717,411,303,424
Yotta Y 2^80 = 1,208,925,819,614,629,174,706,

Check the drive using properties in My Computer and you will see a decimal value of around 80Gig. Drive makers started using decimal values during the drive size wars that started with Win95 was released. Before that they generally used binary.

Mike Meyers has an explanation of HDD as well. When you buy a harddrive, its not guaranteed to have exactly 60 gig or 80 gig, etc. Has to do with low level formatting and allocation, you lose minimal sections on the drive. I read this in his all in one third edition. (back wehen I took the exam)
