I have one problem with my hard drive. I have 1TB capcity . But now it is showing total capacity only 30 GB on hard drive when finishing the copying of system recovery file to hard drive.

If you have a 32bit system, it is expected to have miscalculations, a 32 bits can only go up to 4Gb for calculations (that is, 2^32 = 4'294'967'296 bytes) a 64bit system can make calculations to 2^64 bytes this is also why you couldn't copy a file larger than 4Gb in a 32bit operating system...
So, if you are running a 32bit OS, you should expect a discrepancy for the total space of the Hard Drive and the amount it shows (that's the 93Gb you are missing as total capacity).
Another reason why it can show you incorrect calculations are damaged sectors on the hard drive it-self. These will present themselves either as occupied memory or missing memory.
So, you should expect some miss calculations and you can expect some damaged sectors on the hard disk (a external drive spins on and off too often, eventually damaging sectors... its a problem of physical drives).
In the end, your disk might be fragmented, so run a disk analysis and a defragmentation on the disk so it can recalculate.
A note: A disk is like a shelve, you put things where there is space, if you remove things, that space will be open, and if you want to put something there it has to be the exact size or small enough to fit there. This effect, when things are small enough leaves blank spaces unusable, consuming space on the hard drive and making the access of files slower, this is fragmentation. In order to expand your disk life expectancy you should run defragmentations...
To run a defragmentation, go to START, write "Disk Defragmenter", choose your disk and run and analysis and defragmentation.

The 3.98 GB you are seeing is probably your total RAM memory and not the storage capacity of the hard drive. RAM memory is completely unrelated to the hard drive capacities.

Double click on the MY COMPUTER icon.

You should then see all the disks and drives that are currently connected to your computer. Your USB hard drive should be one of the drives listed there.

Right click on each of them and select PROPERTIES from the menu shown. This will show you the storage capacity of each drive including how much space is used and how much is free (empty).

Good luck.

1) Open any folder on your your computer and go to: Tools > Folder options > View tab > check "Show hidden files and folders" and uncheck "Hide protected operating system files". 2) Look at your hard disk again, if you still can't see any files on it, there must be an error of your disk. To solve it, go to: My Computer (or Win+E keyboard shortcut) > Right click on the drive representing the 1TB hard disk > Properties > Tools > Check Now... > Check both boxes to fix errors.

Hi.

This is normal. You will never get all the capacity for a USB key or a hard drive. The missing space is for format purpose and hard drive maintenance.

Hope it helps

Capacity: 80,000 million bytes
Cache: yes
Interface: Parallel ATA
Speed: 5400 RPM
Cost: probably around $100 US, when new, years ago.

It is up to 1TB per drive. RAM is totally different and has nothing to do with HDD capacity.

If you have windows xp with service pack 3, there is no limit. There is no limit if you run Vistaor Windows 7. If you don't have service pack 3, you are limited to 137 gb.

try re-installing your O/S then delete the partion/s and create a new one it should give you the total capacity after that, post back if you still have questions

I dont think its supposed to copy data in a boot process
copying and booting are totally different processes
Did you mean to say you have hdd issues
