hard drive size
hey guys, so i have a new 1tb hard drive and partitioned 50gb for the operating system. the unallocated size went from ~980gb to 931gb. I deleted the 50gb partition because i wanted to use the full terabyte. However the 931gb did not go back to 980gb. Do you guys know whats wrong?

This can cause some confusion because some operating systems may report the formatted capacity of a hard drive using binary prefix units which increment by powers of 1024. A one terabyte (1 TB) disk drive would be expected to hold around 1 trillion bytes (1,000,000,000,000) or 1000 GB; and indeed most 1 TB hard drives will contain slightly more than this number. However some operating system utilities would report this as around 931 GB or 953,674 MB. (The actual number for a formatted capacity will be somewhat smaller still, depending on the file system)."

Coincidence? I think not. The likely explanation is that you're drive is a 931GiB (1000 GB) drive. This is the standard amongst drive manufacturers. Sorry if this is not readable, I'm a bit drunk right now.
