Nothing different from recovering missing space on an IDE hard disk. Find and delete the files that use that space. The usual tools:
- chkdsk for statistics
- treesize for folder sizes
- cacls or icacls command to give you access to the System Volume Information folder
It's important to do all calculations in bytes (or sectors). Different definitions of Gigabyte differ 7%. And 7% from 500 GB. And 7% of 500 GB is 35 GB. That's just the difference between 500 and 465. That might be the simple answer to your issue.
Definition #1: 1.000.000.000 bytes
Definition #2: 2^30 bytes. That's 1.073.741.824 bytes.
Like the question says, my operating system mystirously subtracted 35gb worth of hard drive space. So that mean that I went from 500gb space to 465gb in total space. So my basic question is, why so? I do I recover or get my o.s. to recognize the missing 35gb of the 500gb sata drive that is intalled? Has this happened to anyone else or is it just me? Any suggestion to solve this problem? or is it just normal?
