Question about Seagate FreeAgent Pro - 500GB, 7200 RPM, USB 2.0, eSATA, External 500 GB Hard Drive
Hi !! I have 500GB HDD installed on my desktop..but when I connect it on the computer it shows 464GB only..even at the time of FORMAT of HDD..it showed the same space
Mostly this is affected by match used to construct the drive geometry. The narrative below is courtesy Tiger Direct of Canada and is their copyrighted content.

Second, some computers have a non-DOS hard drive partition that is used for features such as Save to Disk, Hibernation, or Recovery. This partition is not normally reported by the operating system, although it can be viewed using a disk partition utility. This is very common on desktops and laptops. NOTE: Partition information will be created or formatted automatically during initial system setup and a system recovery.
Third, by default, all system files are hidden and cannot be seen. This may adversely affect the reporting of available hard drive space. You can set your Folder Options so you view system and hidden files and folders, but do be careful as changes to system files can adversely affect your system.
Fourth, if you turn on Compression for a drive, it will increase reported free space and used space, but since compression is based upon the actual contents, this number is not fixed, but will change as files are added or changed.
Fifth, older operating systems did not support some of today's larger drives, so the total space reported may be much smaller than the drive specifications.
It is also worth noting that bad sectors are corrected by your operating system and can change the total drive space, free space, or used space as well.
So as long as a drive is reporting a value approximately close to the specification value, you can be comfortable that you received the right drive and that you are getting to correct data storage. Of course, tuning of your drive's partitions and options can yield optimal values, but this is not something for the average user to explore.

I always figure .93% of the drive manufacturers rated capacity is what you'll have after formating the drive
because advertising a drives larger size is just a marketing gimmick. a drive advertised as 1TB or the same
drive advertised as 930GB remember advertised size sells the bigger the better.
120GB x .93% = 111GB
250GB x .93% = 232GB
300GB x .93% = 279GB
500GB x .93% = 465GB
750GB x .93% = 697GB
1000GB or 1 TB x .93% = 930GB
hope that would help... cheerz!

Hi..there...nothing to worry about it..why?? because hard drive (HDD) need a little space to keep their system program that make it work and detect by your computer.
same thing if you buy HDD with 160GB you will not get pure 160GB but less than 160GB maybe around 154GB ,cause they keep a little space for their system...
