Hi
I have been in the process of buildig up a new PC and have fitted a WD 640 Black Cavier sata HDD and after trying to partition and format it using Ranish Partition Manager and not being successful I now find that the HDD size indicated is now reading 610.479 gig and not the 640gig that the drive is meant to be. I know that a certain amount of the disk is used for the mbr partition but I would'nt have thought it was as much as 30.5 gig.
Can someone let me know if this is the case and if not what might be going on.
The Drive is fitted to a Gigabyte GA-MA790FXT-UD5P m/B as a sole primary drive.
TIA mortda

Some brand consider 1 Gb = 1.000.000.000 bytes , not 1.073.741.824 starting from kB=1024 bytes. Read the manual !

the only info on this disk from the manufacturers web site is that the Capacity is stated as 640 Mb
Formatted Capacity 640.135 Mb
User Sectors Per Drive 1,250,263,728
therefore a formated disk should read 640,135.000 kB at least berfore any partion is created.
