HDD Query

I have recently bought a Laptop which claims to have 100GB HDD SATA.

In properties on the C drive, it states that the HDD capacity is only 87.7 GB. I have only loaded Vista and Norton and I am down to about 68 GB free.

I seem to have misplaced 12.3 GB ?????????????

Should the capacity of the HDD state 100GB?

It could (partly?) be due to the BackUp partition on disc.

Click whatever the Vista equivalent is of Start - Control Panel - Administrative Tools - Computer Managerment - Disc Management and look at the Disc 0 arrangement. It should show how much is in the BackUp partitiion, with the rest in HDD (C:).

Our Windows XP BackUp partitions are of the order of 8GB, but maybe Vista is bigger? HTH.

Holme,

This shows 5.37GB basic drive and 87.79GB for the NTFS giving a total of 93.16GB total.

I am not going to argue about 7GB (100 - 93).

Thanks for the education,

Lil

That makes sense! There's also a little bit of 'creative accounting' as far as disc size is concerned. A disc advertised as "100GB" is actually c. 5% less than that...

The techie reason is that a GByte isn't (as you would naturally think) 1,000,000,000 bytes, but the binary equivalent, which is 1,048,576,000. So a "100GB" disc is actually 100/1.048576 = 'only' 95.36GB.

Funny old thing, you report 93.16GB which - let's face it - is pretty darn close. There's lies, damn lies, and disc capacities... :-)
