WHS 2011 hard drives allocations? RRS feed

  • Question

  • Hey Guys, Another WHS 2011 newbie here with (I hope) an easy couple questions.

    Bought a New Dell Power Edge 410 with a 1TB HDD. The drive came formatted as a 60GB C drive and a 870.9GB D drive. What was the point in this? I know there must have been a well thought out, tried and proven reason but I'd like to know why so I'll lay it out right the first time?

    This server came from Dell with a PERC 6/i RAID controller. I added 2 ea 2TB HDD and set it for RAID. One 2TB for data and a laptop backup, 2TB mirror.

    What I see is a single 1862GB and where did 138GB go?

    I'm new to using a server and while everything is new and I have nothing to loose, I don't want to just blunder in trying to fix things without advise.

    Thanks in advance.

  • Nothing wrong. Drive manufacturers measure disk size in powers of 10, so a 1 TB (terabyte) drive is 10^12 bytes, while Windows uses powers of 2, so a 1 TiB (tebibyte) drive is 2^40 bytes. The difference in measuring methods results in the difference you see.

    I'm not on the WHS team, I just post a lot. :)
