I'm using a laptop with Vista Home Premiuim 32bit. The stated hard disk capacity 
is 160 GB. I have made 6 partitions of various capacities. The total capacity adds 
upto only 148.7 GB. Is this normal? I was using XP before shifting to Vista. While 
installing Vista, 21 GB of space appeared as unpartitioned space from nowhere. Due 
to that I have 2 primary partitions. XP didnt show this space at all when I was using 
it. Please clear my confusion. Thanks in advance

Unallocated space will only show up in Disk Management.

Perhaps your version does not have SP2 built in, so if you used that to partition your hard drive it wouldn't have reported the full 160 GB. And regarding the issue that others are mentioning, basically it just means that depending on what is reporting the hard drive space, it may be slightly overstated/understated. So don't be alarmed if it seems that you have slightly less than the expected 160 GB's, this is normal.

By definition you are only allowed 1's and 0's. 168 g -dec = 10011100011101100101001001000000000000 -bin 2343545110000 -oct 271D949000 -hex Do YOUR math This persons missing drive size is caused probably by two things. 1. All drive are sold as a certain size, but the basic tables and data that must be written to disk in the initialization and formatting process take up some of that space. 2. Many Manufacturers put hidden sectors on their disks for backup/restoration purposes. These would be the most common causes. This is not to be considered all inclusive though as not knowing the practices of his particular and not physically having the drive to study, I nor no one else could possible make an informed statement of fact as to where the missing bytes are.
