A couple years ago I bought a 40 gb portable HD with FAT32 format. I believe it is 40 gb since it is clearly labeled with 40 gb on it. When I plugged into my XP pc, it shows the portable HD is with only 4.86 gb. Again it is a WD USB portable hard drive, not a thumb drive. The model is WD400U017-RTN
Actually, I didn't notice that until I tried to copy about 5 gb picture files to it and got a 'not enought space' error. I was shocked to find it is only 4.86 gb. How could it be ??
Can you figure what is wrong? How to get 40 gb back ?
