is it close enough to be reounding errors?
Did garbage collection and or trim kick in yet?
Also, small files will take up a fixed amout of space regardless of how big they are.
IE - a 1 byte file will take up the the whole sector (often 512 bytes) as the sector is the smallest unit the OS can assign to a file. a 4k file would take 8 secotrs, a 4.01k file would take up 9 sectors (4.5k). I'm not positive but windows might be calculating the used space and file space differently
It started off to be about 3gig worth of difference. Through quite abit of installations I did yesterday, the difference seems to have gotten smaller to about 1.8gig currently.
It seems that maybe the drive space indicator might be calculating the space erroneously.
It still is peculiar because people always tend to be experiencing the reverse (files sizes much less than indicated used space). There hasnt been a report of this so far that I have managed to search in google.
I will continue to monitor the usage over the next few days. Thanks for your response.
