Where have all the hard gigs gone?

Here's one for the nerds...my hdds seem to have lost around 5% of their capacity.

 

Started life with 2x200, and all was fine on that front for a while.

 

Checking hdd status immediately before partitioning, they showed (as current) 186 + 187 with Explorer, whilst Partition Magic gave them (as current) each 190.779 post-partition.

 

I have run through all diags that my limited knowledge and software allows, and every disk check and test shows all in order, but somewhere between installing XP and partitioning the drives seem to have lost 14 + 13 gb, which was somehow reduced to 9+9gb after partition (10'ish under treesizepro).

 

All partitions use NTFS.

 

 

Current status (explorer/properties) reads:

 

C: 11.9 used + 37.2 free = 49.1

G: 21.0 used + 116.0 free = 137

total: 186.1

 

D: 6.55 used + 81.3 free = 87.85

Z: 32.4 used + 65.9 free = 98.3

total: 187.15

 

 

Current status (partition magic) reads:

 

C: 12.243 used + 38.108 free = 50.351

G: 21.556 used + 118.871 free = 140.427

total: 190.779

 

D: 6.71 used + 83.326 free = 90.036

Z: 33.242 used + 67.501 free = 100.743

total: 190.779

 

 

Current status (treesizepro) reads:

 

C: 12.638 used + 38.109 free = 50.747

G: 20.658 used + 118.871 free = 139.529

total: 190.276

 

D: 6.420 used + 83.326 free = 89.726

Z: 32.359 used + 67.501 free = 99.860

total: 189.576

 

 

I realise the three progs may be using different criteria to examine disk space, but I would be happy if just one gave me the target reading.

 

 

Thanks in anticipation, and again all round for the enormous public and PMed responses to my previous dilema.

I know that will be not much of a help but if you try to install any Unix based OS you will no doubt be able to use the full capacity of the Disc.

 

Anyway, if your windows versions sees it as 187, this is about right for the following reason:

 

HDD manufacturers see it as 2x10^11 bytes, and when you divide it by 1024 (KB), 1024 (MB), and 1024 (GB) you get roughly 187GB.

 

Even though they sell you 200GB technically that is not correct.

 

So actually its not so much that you lost it.. you never had it to begin with.

 

a 20 GB has 19 531 250 KB = which would be 19 073.48MB = 18.626GB (1.37GB unuseable)

 

a 200GB has 195 312 500 KB = 190 734.86MB = 186.26GB (13.73GBs unuseable)

 

cheers

I see, cybers, but when the puter was new and unpartitioned I naturally checked the disk sizes and explorer's breakdown of used/free space totalled 200 on each. Seems somewhere between then and partitioning it resolved the issue. Fair enough, and many thanks.

Not all, monkey, not all; only 5% casualties.
