    Free SSD C:\ drive space. Mysterious additional 26 GB!
    « on: October 27, 2010, 06:52:57 AM »
    Hi all,

    I'm really confused about this issue. I have a 60 GB SSD drive which I use to run my OS(Win 7 Pro x64) and a few specific programs from. Not long ago its storage icon has become red due to the fact that it's reaching its maximum storage of 60 GB. Now I ask myself how this is even possible. If I open Computer and select everything on C:\ (ctrl+a), and check the properties I see that the total size of these files are only 34.1 GB. The selection includes the windows folder itself and my program files folder along with everything else. Where the heck are the additional 26.1 GB that I for some reason can not see?

    I have already set my account associated folders such as My Documents, Pictures, Music etc to be stored on my other D:\ drive, so that's probably not the issue here. And I have also checked hidden files without luck.

    Any help much appreciated.

    You might want to see if the SSD manufacturer has issue firmware updates.  I have an Intel SSD and shortly before I bought it Intel issued a software upgrade to implement a feature called 'Trim' which is essentially a 'defrag' feature.  Running a standard defrag program on an SSD reduces it's useful life because of the writes and rewrites a regular defrag program does.  There is the possibility that your extra 26 GB are fragmentations of the programs on the drive.

      Interesting idea, never knew that was possible.

      Here's the model (CMFSSD-64N1): http://www.corsair.com/products/ssd_legacy/default.aspx

      Can't find any form of trimming programs unfortunately. More ideas anyone?

      That's a big joke  :P. Had to run a whole bunch of custom tweaks to get it stutter free.

      System Volume Information, which stores All System Restore points as well as Volume Shadow Copy data.
      I was trying to dereference Null Pointers before it was cool.

        Thanks, that sounds like it.

        Is there any way to disable the shadow copy? How important is it?

        Just disable system restore if you like. And instead you can start using disk imaging software on a regular basis.

        You may find this article helpful: http://www.pcmag.com/article2/0,2817,2342534,00.asp

        My C: drive is 80g and following the instructions in this article to bring up the vssadmin list shadowstorage data, the maximum Shadow Copy Storage space is 5% or roughly 4 g. It says nothing about the Restore function though.  Even so....

        In Command prompt run below said command (in Administrator/elevated command prompt)

        vssadmin resize shadowstorage /on=C: /for=C: /maxsize=4GB

        This will reduce the size max to 4GB.

        Have a good day
