What are the actual capacities of hard disc drives: 20BG, 40BG, 80GB etc?

Always figure you get roughly 7% less than the rated storage amount. \n\nManufacturers decided to rate most drive capacities based on the standard base 10 numbers we are all familiar with, but the actual measurments are in base 2.\n\nTherefore, one Megabyte equals one million bytes while one Gigabyte equals one billion bytes. This isn't too much of a problem with fairly small numbers such as a Kilobyte, but each level of increase in the prefix also increased the total discrepancy of the actual space compared to the advertised space.\n\nHere is a quick reference to show the amount that the actual values differ compared to the advertised for each common referenced value:\n\n    * Megabyte Difference = 48,576 Bytes\n    * Gigabyte Difference = 73,741,824 Bytes\n    * Terabyte Difference = 99,511,627,776 Bytes \n\nBased on this, for each Gigabyte that a drive manufacturer claims, they are over reporting the amount of disk space by 73,741,824 Bytes or roughly 70.3 MB of disk space. So, if a manufacturer advertises an 80 GB (80 billion bytes) hard drive, the actual disk space is around 74.5 GB of space, roughly 7% less than what they advertise.

nice tried explanations above, but the most are wrong. your system can't overcome the so called 32GB barrier. With a 40GB disk you should see approx a size of 37.2 GB what can be explained with the above mentioned calculation methods, but the true reason is still the 32GB barrier.\n\nRead the following article "Hard Drive Size Limitations and Barriers"\nhttp://www.dewassoc.com/kbase/hard_drives/hard_drive_size_barriers.htm\nto overcome this barrier go to the disk manufacturers website and look for a software tool that can resolve this problem. for example Maxtor has the tool called MaxBlast 4.

20... thats 2^20...1048576 bytes...some companies say 1,000,000 bytes to make their hardrives/flash memory seem bigger but 1048576 or 2^20 is technically the most accurate answer...

Ouch, get a DVD burner (Dual Layer).  Cd's only store less than 1gb.  That would leave you making 100 cd's for 70gb of data.

1GB = 1024 MB\n1MB = 1024 KB\n\nso advertised hard drive capacity is not the true capacity due to this factor.\n\nWhen you format the HDD, it's partition (FAT/NTFS) strucure itself requires a space.\n\n\nAlso, when files are stored & creates in hard drive, it's saved as "clusters" which usually takes more space than actual size.\n\nThink of putting books in a box.  The books will not completely fill the box, leaving some spaces & gaps.  Same with harddrive.

if you dont need the stuff in youf hdd, format and install a new os, then you have everyspace available for you\n\nbut\n\nif you want the stuff that is already there and still want to free up space, you can try disk defragmenation\n\nor else..if you have cd/dvd burner copy all important data to those removable discs and you get your free space\n\nOnly the first and third options can give free up space upto 20Gigs, so choose wisely\ngoodluck

first off 3 gb is a bit on the small side so you could move the files to a second hard drive. \ncompressing files is an option. another is removing some programs.

Its all about the storage space of the computer. \ni.e. 40GB has 40 giga bytes of storage space on the hard disk of the computer. \nand 80 GB hard disk will have 80 giga bytes of storage space. So, you can store more data on 80GB hard disk than on 40GB hard disk.

N,because the hard drive has more strorage capacity than the cd-rw drive

there is no limitation........ and theoratically its about 160GB......... but at now many tools are available which makes your harddrive NTFS even if you have more than this bytes. but exactly research telling about more tahn 32TB

I would assume you got that on ebay from hong kong...they compress the drive to make it hold more and when you format it you take it back to its orriginal/correct size....you got screwed! I have not figuered out how to make it take 2 gigs again....I run a computer shop and I just had a customer with the same problem.\n\n-Doc-

I down load a lot of files and my 60GB hard drive is quite adequate as I archive old files on a DVD

No, both hard drives are 4.3 GB. Just check for bad clusters (format it) and if they are OK you can use them

Enable 48-bit LBA Support for Large Hard Drives should help you out.\nhttp://www.winguides.com/registry/display.php/1115/

a gigabyte, or GB is 2000KB\ngiga = million, kilo = thousand (kg=kilobyte)

practically unlimited.  you can get a terabyte hard drive. (that's the largest that I've seen made so far)
