I read the answer someone gave about an indexing table and chuckled as that is the wrong answer. The reason the drive doesn't show as 4TB in your OS is because, since the beginning of time, hard drive manufactures consider 1 kilobyte as 1,000 bytes, 1 megabyte as 1,000 kilobytes, 1 gigabyte as 1,000 megabytes and 1 terabyte are 1,000 gigabytes. That is a marketing gimmick. In reality 1 terabyte is 1,024 gigabytes and so on down the line. That means manufactures consider 1 terabyte as 1,000,000,000,000 bytes, but in reality 1 terabyte is 1,099,511,627,776 bytes, because computers are binary systems (powers of 2). So a 4 TB labeled drive isn't actually 4 TB, it's actually a bit less, because manufactures are using the wrong value to represent gigabytes, terabytes, etc. as a marketing gimmick.
Sorry, there was a problem. Please try again later.1 KB = 1024 Bytes 1 MB = 1024 KB 1 GB = 1024 MB 1 TB = 1024 GB So 1 TB is actually = 1024x1024x1024x1024 Bytes Which means 1 TB = 1,099,511,627,776.00 Bytes When manufactures sell a 1 TB drive they actually mean a 1,000,000,000,000 (1 trillion Bytes)....which is not equal to 1,024 GB 1 trillion bytes is actually equal to 0.91 TB = 910 GBP That means a 4 trillion byte drive = 0.91 TB x 4 = 3.64 TB So manufacturers are using this trick to make you think you're getting a 4TB drive when your actually only getting a 4 trillion Byte drive or approx. 3.64 TB
Sorry, there was a problem. Please try again later.http://forums.whirlpool.net.au/archive/2309652 That site gives table of different TB drives & how much it is when computer using "base 2 computer language" instead of the decimal (base 10) that it's sold in, shows how much space the drive provides. The 3.63 is about 9% less than 4. (3.63/4=90%). So about 9% is lost
Sorry, there was a problem. Please try again later.4 TB is the over all size. 3.63 is normal for the indexing table. The table usually takes up 8 to 10% of the total drive.
Sorry, there was a problem. Please try again later.mine had a bunch of pre-installed software on it and the 4TB number may be the unformatted spec.
Sorry, there was a problem. Please try again later.You can try reformatting the drive to gain more room.
