 |
|
Can anyone tell me how to calculate the number of bytes per partition based on the number of blocks fdisk tells me I have?
This is what I have figured and I'm not sure if it's correct:
I have 3 250GB harddrives. The first one I'll use in my example. It has 4 partitions, including one for swap.
| Code: | Partition - Blocks
/dev/sda1 - 71681998
/dev/sda2 - 71682030
/dev/sda3 - 10241437
/dev/sda4 - 90590535 |
What I have figured is if I divide the number of blocks by 1024, and then divide the result by 1024 again, I get a number that looks right.
So I have this:
| Code: | Partition - Size (GB)
/dev/sda1 - 68.36
/dev/sda2 - 68.36
/dev/sda3 - 9.77
/dev/sda4 - 86.39
Total - 232.88 |
Now this looks right to me except for the 10GB of swap space. I cant imagine giving that much space to swap but who knows. Can anyone confirm or know of a better way to calculate disk space based on any of the information fdisk gives?

| That is where I'm getting the information I'm talking about, but it doesn't provide the number of bytes per partition. |

fdisk displays 1024 byte blocks, so your calculation is correct. |
