IAM HAVING 80GB HARDDISK BUT IT IS DETECTING ONLY 74.53 GB WHY?? WHAT IS THE REASON?

Question

iam having seagate 80gm IDE HDD.iam using win xp os.

Answer 1

This is normal.  The rest part of your HDD may be reserved by you OS for some memory usage and system file usages

Answer 2

Don bother about dat dear.Everything is perfect.What happens is dat no storage device can work perfectly w/o having some necessary resource files.These resource files occupy some space on the disk.So NM.

Answer 3

the remaining part is full of with BAD SECTORS

Answer 4

yeah, they lie - whilst your hard disk may have a capacity of 80gb, there are system files and **** which take 5gb, and you can't use your disk without them there.

this is because the disk has to hold information about the file system type, and other special data, depending on the type.

you'll have to live with it, there's no way around it.

Answer 5

The truth is that Hard Disks are manufactured such that 1 Gigabyte is 1,000,000,000 Bytes.  

However in a computer 1 Megabyte is 1024 bytes and 1 gigabyte is 1024 Megabytes. 2^10 = 1024  (the closest a power of 2 gets to 1000)

2's use in computing is because thats is the number of states in each bit 0 or 1.  so you can represent 1024 states with 10 bits.

Anyway. you will find that 80 GB /1024/1024 =76.29 GB in computing terms.

As previously stated you have a MBR or master boot record and other protected areas of your disk which are unwritable.

Also if any sectors go bad they will be flagged as unusable too.

Hope this helps you to understand. Cheers.

Answer 6

yes this is exactly even I have... Seagate 80Gb hard-disk, and it shows 74.53 GB.

This is because of the system files which are required for proper functioning of the hard-disk... You can't remove those. So be happy with what u got... :)

Answer 7

It is not a problem. every HDD has this situation. other hidden capacity is takes for system files. So don't worry.......

Answer 8

That is just the way it is.

I also have 80 GB hard disk and XP OS and the computer only dectects my hard disk capacity as 74.5.

Also, take a look at this explanation:

Hope I cleared things up :-]

Answer 9

There's a simple reason for this: your hard drive really isn't 80GB

The reason; the hard drive companies say that 1000MB=1GB

However, to a computer it's 1024MB=1GB, so the actual number of GB is always a bit less than the hard drive manufacturer says it is.

It has NOTHING to do with "system files" like several people are saying.
