All hard drives including Transcend`s StoreJet series will display a lower than stated capacity when they are viewed on a computer. The reason for this discrepancy is the way in which hard drive manufacturers calculate a megabyte of memory.
Windows calculates a megabyte, or 1,000KBs (or 1,000x1,000 bytes), as 1,000KBs, when in fact the correct calculation is 1,024KBs.
So, for a 320GB hard drive, Windows will calculate the hard drive as having a capacity of 320,000,000,000/1,024/1,024/1,024=298GB
