All this has become abit of a moot point as since i attempted to run a hdd check in rescue mode. The server will no longer reboot from the hd?

so maybe i now have bigger fish to fry :lol:
The bug is the software reporting 250GB as 232.8GB

That's the size of the partition.

When you create a file system on a partition, the file system structure itself takes some of the space, and some space is "reserved" (default 5% for mk2fs).

The software that is telling you 232.8 GB is wrong. It should be telling you 250GB.

I wanted to test it in rescue mode as it was apparent i had lost a fair bit of space.

Any ideas what i can do to remedy this please?

Nearly right Iain.

Manufacturesr call 250 GB 250,000,000,000 bytes so when you divide that by 1024^3 you get 232.8 GB.

Let's work this out. HDD Manufacturers usually quote 1 GB as 1,000MB. Linux reports 1 GB as 1,024MB because that's what it is! You can't divide by 5 or 10 in bytes!

Anyway so 250 GB should be equal to 250,000 MB. Now if we take 250,000 MB and divide that by 1024, as we should, we are left with 244.140625GB. This doesn't account for all that you are loosing but possibly when you take the MBR, File system tables, formatting etc in to consideration you are left with 232.8GB usable.

I know that my 250GB hdd appears as 232.X GB in Windows Server.

What you see is most likely correct.
