I have installed a Seagate 80 GB hard drive, but when I check the capacity it's showing 65 GB. I have had problems with my computer recently and have had to reformat the hard drive, before this the hard drive was showing 80 GB. Could someone please help me find my missing 15 GB.
 
Like most of people you have just learned that manufacturers are imporperly listing the size capacities of hard disks. Hard disks should be measured in multipliers of 1024 but manufacturers are actually listing them in multipliers of 1000.

A Megabyte is actually:
1,024 Kilobytes or 1,048,576 Bytes

A Gigabyte is actually:
1,024 Megabytes or 1,073,741,824 Bytes

Check the bios...and make sure the system is detecting your hard disk correctly.
Even if the above post were correct, that would only account for 66 1/2.

Exactly what problems were you having that led you to reformat?

The more I learn,I realize how much more there is to know!
 
Did you use fdisk to set up the partition? Although this article doesn't really fit with your symptoms, fdisk can have problems with > 64GB disks
jsauce is correct about different definitions of gigabyte, but it doesn't account for 15GB (80,000,000,000 bytes, which is what your drive will be is 74.5GB on the most 'pessimistic' definition).

What o/s system are you using? (and as Kimbertech says, what problems were you having).
 
I am using Windows ME, the problems I was having before reformatting were 'low system memory' and most programs when accessed were freezing on the computer. I also had 3 partitians using partition magic, the sizes were 10 GB, and the remaining Gygabytes were then split into the remaing 2 drives. When I got rid of partitian magic that was when I noticed the missing Gygabytes. My memory is a Crucial 512 MB DDR chip.
 
I got the partitian details off partitian magic info, but since reformatting I have only the 1 drive which is c: and that is showing 65546 Mbytes and total disk space is 76317 Mbytes, I got this info from fdisk.
 
You might have gotten a mislabled drive. You should probably return it and get another one. John D. Saucier

So, will fdisk let you create another partition in the remaining space? Did you use fdisk to create the new single partition, and specify to use all available space?
