new to fixing computers ...I need help hope im in the rite place ..I have a computer running windows 7 64 bit .I had a 80 gig hard drive that was going bad so I replaced it with a 320 gig drive. I did a create image with an external hard drive to transfer all info to the new hard drive..every thing work but the 320 gig hard drive only shows 298 on my speccy64 program.and I have 4 gigs of memory (ram) but it said only 3.49 usable....please help!
Here's an example:
320GB = 298GB
500GB = 465GB
This is because there is a 7.37% pseudo-overhead in capacity with hard drives.
Like your hdd is 320gb let me do this the mathematical way.
1GB = 1.074GB
320gb divided by 1.074 = equals 298GB actual size: 297.951582868
My 2tb hdd is 2tb but only shows 1.81tb same thing 1000 divide by 1.074 = 1862.19739292 or less
This is why you see 298gb not 320gb. Because there is a 7% pseudo-overhead in capacities with all hard drives.
With the RAM you said 3.49GB usable out of 4GB
However not all 4GB of the RAM can be used (the unusable 0.51GB is only preallocated for graphics in the BIOS)
Answers your question mate only learnt about this in I.T 2 Days ago...
