Usable and Actual Space on Hard Drive 2

[GGROD]

I just bought a 160GB hard drive and when I look at the drive in Disk Management under Win 2000 it says I only have 128GB of free space. This seems low to me. Shouldn't I be able to use at least 90% of the drive?

Has anyone heard of this and does it work?

I would like to split this drive into two equal partitions. What is the actual number in megabytes that I should enter for each partition? I don't believe I can enter 80000 MB for each partition.

After reading previous posts I find that the drive is only about 149GB. And I probably need to see if I need to download the latest service packs for Win 2000.

So if it is about 149GB of usable space what is the actual number in megabytes that I should enter for each partition? I don't believe I can enter 75000 MB for each partition.

Do they have to be exactly equal?

When you've enabled 48-bit LBA support -

disk management should tell you how much space is available when you go to create partitions. Just divide the number displayed by 2 (if you don't like the results, you can always delete partitions and start again - or get another partitioning tool - but must admit can't see that its a big deal!)

OK. First of all, the 160GB advertised by hard drive companies is going by the assumption that there are 1,000,000,000 bytes in a one gigabyte. But in the PC world (the real world), everything runs on a multiple of 1024:

1024 bytes = kilobyte
1024 kb = megabyte
1024 mb = gigabyte
and so on..

So before you know it, you get 1,073,741,824 bytes in a gigabyte (that's 73 million bytes more than what was advertised). Sounds like a rip-off right? Well if you do all the math, 160/1.073 = 149 real GB approximately. There's that answer.


As for partitioning, just use the multiple of 1024. So if you wanted a 75GB partition, you would use:

75 x 1024 = 76,800MB
