PERC wasted space

I put a 1TB SATA disk in a Dell server with PERC RAID controller and configured that disk as a single virtual disk (IE the disk gets a RAID signature the PERC likes and is passed through to the OS). The disk when viewed on a regular SATA controller has 1953525168 sectors, when it goes through the PERC it has 1952448512 sectors, that is 525MB less space when going through the PERC! That's 1% of a 500G SSD. Is there any way to configure PERC to reduce it? Is using "HBA" mode worthwhile? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
