Solved HDD's not showing full capacity

Specs: Microsoft Windows Vista Home Premium, 1.9 GHz / 2813 MB
Hi There,
I'm running Vista Home Premium. I have a laptop with a 300 Gb HDD. If I right click properties it only shows up as 211 Gb. If I got to Disk Mgmt it shows up as 232 Gb - 211 Gb in my main C Drive, NTFS Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition); 10 Gb more Healthy (Primary Partition), with no assigned drive letter; 9.5 Gb (Unallocated); and another 1.5 Gb Healthy (EISA Configuration).

If I right click my external 1 Tb Drive, it shows up in properties as 931 Gb. In Disk Mgmt it also shows up as 931 Gb NTFS Healthy (Primary Partition - assigned drive letter E.

In reading previous posts here, there seems to be a lot of mention of installing SP 3 in order for Win to recognize the drives. In Control Panel > System I show SP 2 only. Am I even heading down the right path with this? Any help appreciated.
Thx
Tim

The 1 TB drive showing as 931 is about right. It has to do with counting bytes as binary or decimal. Check my posts in this old thread:

http://www.computing.net/answers/ha...

I'm not sure about the 300 gig drive. It's showing total disk space as 232 gig which is about 250 gig when converted to decimal counting, which is how the space was expressed on the factory drive specs.

Could it actually be a 250 gig drive? If you're sure it's 300 then maybe there's a hidden 50 gig partition but I think that would show up in disk management.
You might check in cmos/bios setup to make sure the drive is seen accurately there. That possible bios limitation wouldn't apply to the 1 TB drive since the bios doesn't configure external drives--the OS does.

I don't think Vista should have any problem seeing the full space, especially since it's doing OK with the 1 TB drive. It was XP that needed at least SP1 to see large drives.

Y'know now you've piqued my curiosity as to whether or not the HDD is actually 300 or 250. I just checked and the generic manual I have for this Toshiba model only refers to the HDD in general terms, not specific size. I live in Canada, but I bought the computer in China nearly two years ago, at a large department store recommended to me by some students (not black market). I'm sure it was listed as 300 Gb, but maybe I was sold 250?? Honestly I can't remember in the past what it showed up as. It's only become an issue now as I am running out of space even with the 1 Tb backup (lots of video editing). So I think if you are counting the 232 as near 250, then that's probably what I got. No chance now of going or the store to confirm. A new laptop or backup is about a quarter of the cost of heading to the store in China to find out! Thx for your input.

You're welcome. I'm not sure how the hard drive is tucked away on your Toshiba but you can probably remove the cover over it and check the label on the drive. Or the model number and capacity should show in cmos/bios setup.
