    Hey guys!

    I have 12GB free space on my HDD and it seems to be constantly decreasing the more i use my MBP.
    It is currently at 9GB and keeps on decreasing.

    I went to applications>utilities>disk utility and checked the S.M.A.R.T. Status : Verified

    Is there a problem with my HDD??..or maybe it's a virus??
    Can anyone help me fix this??

    Thnx

    MBP 13" 2.26Ghz, 160 HDD, 2GB Ram, Mac Os X 10.6.6

    First, it can't be a virus, since none exist that can run on current Mac OS X.
    Next, open Activity Monitor and look at your Page Outs under the System Memory tab at the bottom. What does it show? Also, have you rebooted and does the available space change when you reboot?

    You don't need to delete them, unless they're abnormal in size. Did you read my post?

    I see you only have 2GB of RAM. If you routinely max out your RAM, Mac OS X begins paging memory to your hard drive. The swap files created by this process grow as your paging activity increases. Rebooting removes swap files and you start over again with freed up hard drive space. If this happens frequently, you should consider increasing RAM. If swap files are, indeed, the culprit here, increasing RAM will not only free up hard drive space, but will give you faster overall performance, since paging activity slows down your system.

    You can also look at Activity Monitor's System Memory tab and make note of "Swap used:", which tells you how much of your disk space is currently used up by swap files.

    I'm starting to think that these swap files are the problem! I use skype(approx. 95mb) , itunes(approx. 80mb) and safari(approx. 260mb) almost daily and there's also flash player safari plug in(approx. 141mb)!!
    So what should i do by the time i upgrade my ram!??

    thnx for your time and the advices!

    I don't understand your question. By the way, what do you show for "Swap used:" in Activity Monitor?

    Well, currently your swap used is only 263MB, but you said you have 3GB missing, so swap files are less than 10% of your problem. Keep an eye on it and see how much it grows over time.

    Use Disk Inventory X or Grand Perspective to see where the extra space is going.

    Just upgrade your drive. It's simple to do, and drives are cheap. It can't possibly be worth this much heartache over whether or not 3gb is full.

    ... except upgrading the drive doesn't give the performance boost that upgrading RAM would give, and the RAM is cheaper and easier to upgrade.

    I had a similar problem, HDD went from 84GB used to 120GB used over a months period of time, without loading many downloads. This situation was accompanied by many "pinwheels" when opening or switching application. And size of Time Machine BU was staying about 90-95GB.

    Ran the Apple Hardware test, and found that my optical drive needed repair, but it did not report anything regarding the HDD.
    Made arrangements to have the Genius Bar troubleshoot the optical drive, which they did and it was replaced.
    I told them about the excessive pinwheels, and they diagnosed that my HDD was stating to go bad, which they eventually replaced under warranty. I asked for failure details and all they said was that it was starting to fail. So I am just guessing that my HDD had bad sectors and data was being moved/copied to what the system thought were good sectors.

    My advice - if it is not too inconvenient, make an appointment at the Genius Bar and see if they can diagnose the problem, otherwise contact Apple care.

    And make sure that you have backed up your system.

    with 9gb free, I think you will get more bang for your buck replacing the drive. Personally, I'd add memory AND replace the drive, but with 9gb free, that'd be the highest priority.

    Not really. RAM will run you $50-$100 for 4-8GB while a HDD will set you back $50-$100 for 320 GB to 750 GB.

    Both require you to take the whole back cover off since it is a unibody 13" MBP.

    Like grawk, I'd say go the middle route and get both a RAM and HDD upgrade each for ~$50 and end up doubling both your RAM and HDD space.

    I wanted to upgrade my ram but the local retailer said it'd cost me around 170£ for two 2GB RAM modules...i can't imagine what the HDD would cost me!!

    So your optical drive was faulty!??
    i can't find the link between the decreasing HDD space and the optical drive!!
    :|
    Does that mean that there's a probability i hav a faulty optical drive too and a faulty HDD!??

    I'll try the Apple Harware Test!

    Thnx!!

    in addition to swap files it also could also be the sleep image which is your RAM contents which is stored when the MacBook sleeps. so 2GB in size for your RAM size.

    Get rid of the log files, but leave the sleep/swap files alone. The OS depends on them being there and will have a cow if you mess with them too much.

    Note that if you upgrade the RAM without upgrading your HDD more space will be used up by the sleep image and swap files so you will end up wil less swapping, but also less free space on the HDD.

    Don't have your retailer do the upgrades, you can actually do them yourself without any issues. Just follow the guides at iFixit. http://www.ifixit.com/Device/MacBook_Pro_13"_Unibody_Mid_2009

    This HDD would set you back less than GBP40 e.g. http://www.ebuyer.com/product/136790

    And the RAM can be had for GBP40 http://www.crucial.com/uk/store/lis... Core 2 Duo (13-inch DDR3) MB990LL/A Mid-2009 (I think I got the right model though you should double check).
