Free space of hard drive in the MacBook air changes seemingly at random

In recent days, my hard drive went a few GB of free space, zero KB. I check with clean my mac and see, first that my free space of RAM with the passage of time is reduced up to 10 mg and space free hard drive then start reduced up to zero KB and after 20 sec RAM & hard return to normal space (increased).

What is the problem?

You seem to be two distinct topics: storage and RAM. It is normal that all RAM to use. Please read the section of memory to use the activity monitor to your Mac - Apple Support.

Never use a 'cleansing' of utilities for any purpose. Uninstall "CleanMyMac.

  • Free space on hard drive for HP PROBOOK 450 G0 - H0U95EA

    Hello

    I'm looking for a laptopo HP, I would like to know the free space on hard drive for HP PROBOOK 450 G0 - H0U95EA.

    In the datasheet there are 750GB but in a boutique internet... I found that free space is that of 320 GB, is it good?

    Thank you!

    Marco

    More new software installs would more or less 60 gigs and a 750 GB drive reads as on 690 concerts in Windows Explorer. There will be a recovery partition and system partition that could take up to another 20 GB or more. Free space out of the box is still more than 575 casual jobs. That will decrease as games for Windows restore points.

  • Free space on hard drive shown incorrectly

    My drive C (SW_Preload) has about 200 GB of space. When I click on 'Computer' in windows Explorer, it says that the total free space is 20 GB of used space 180 GB IE. However, when I select all folders and files on my C drive and select properties it shows the total size on disk is only 70 GB. I don't have this with the other readers (Lenovo and SERVICEV003).

    Does anyone know why this is so? My basket is empty and runnign short space when I know that there is still plenty of space on the drive (the laptop is only 3 months and I copied only 1-2 records this to that).

    Hello Hitchkee,

    Thank you for choosing Microsoft answers forums for Windows Vista. I hope you do well.

    To reduce the number of unnecessary files on your hard disk to free up disk space and help your computer run faster, you can use disk cleanup. It removes temporary files, empty the Recycle Bin, and removes a variety of file system and other items that you no longer need. Follow the link below for more details:

    http://windowshelp.Microsoft.com/Windows/en-us/help/1264bc24-72a8-48AA-84e3-a355327139d91033.mspx

    There are a number of issues that contribute to the difference:

    Hidden and system files -Windows Explorer display above was using the default settings that do not display the files marked as 'hidden' or 'system', and therefore, they are not included in the calculation. Change this setting increases the "size on disk" by about 7 gigabytes that all the hidden files on my machine have been included in the calculation. In particular, which included the system pagefile and hibernation, which are large file and marked as hidden.

    To change the settings, you can follow the steps below:

    Start Windows Explorer, and then:
    Click on the Tools menu
    Click the folder menu item Options...
    Click the view tab
    In the advanced settings list, scroll down until you see the hidden files and folders and Hide protected operating system files.
    Make sure that the hidden files and folders is selected. I also uncheck Hide operating system files - for the same reason protected: I don't want to hide it from me, the Windows files.

    Directories - directories, or lists and indexes of files on your machine are not the files themselves, but they don't take place.

    The Table of Allocation of file or the master file Table - FAT itself, Hall of Fame of FAT file system, is actually pretty low. The MFT, however, used in NTFS file systems is also stored on the disk but not visible as a file. It defines where the used and free space on a drive is actually. Depending on the size of your drive, your files and the size of the allocation unit, the MFT can be quite large.

    The log file - this is a file, but even once, you won't see it. It's NTFS internal data.

    Hope this information is useful.

    Kind regards

  • Update hard drive in the MacBook Pro (early 2015)

    What type of SSD will work in a MacBook Pro 13 inch screen of early 2015? I was told by someone that Apple no longer use the SATA drives and they now have their own exclusive hard drives and hard drive connectors. Can someone clarify this for me? I want to upgrade a 256 GB to 500 GB drive.

    New mac systems use style card SSD instead of 2.5 in block style (search for mSATA and M2 style SSD).  Apple uses a protocol of interface owner so you can not buy any card SSD on shelf.

    Another use main contributor a low profile SD card like this http://www.microcenter.com/product/441001/128GB_SDHC_Flash_Memory_Module that can stay connected to the SD slot card all the time and not poke out.  Also external fencing to swap nu-disks for a virtually unlimited storage.

  • Upgrade Windows XP to Windows 7 has no enough free space on hard drive

    Hey, I'm trying to move from XP to 7 (custom installation), and after a while, you have to choose where you want to install windows 7, so I chose the disk which has more than 100 GB of free space, but the thing tells me that its not enough free space... Please help.

    Greetings

    Albert

    Did you start the Windows XP installation?

    You have external storage devices connected to the machine? If so, disconnect them all. In addition, if you have several internal storage devices, disconnect them all except the target device where Windows will be installed.

    Boot from the Windows 7 DVD
    Click Install now
    Accept the license agreement
    When the option is displayed to select a type of installation, click (Custom advanced)

    Select the disk partition where you want to install Windows 7 click Next.

    You will receive the following warning:

    The partition you have selected may contain files from a previous Installation of Windows. If so, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will be able to use your previous version of Windows.

    (At all costs, do NOT click on anything in Format, deletion or Partition name.) So even do a custom installation, your personal files are still kept. Click OK

    The installation program will now begin installation. During installation, your computer will be restarted several times.

    Once the installation is complete, you can complete the Out of Box experience as the choice of your laptop, create a username, password, your time zone. You can then proceed to download the latest updates for Windows and reinstall your applications and drivers.

    You can then retrieve your personal files from the Windows.old folder and reinstall all of your applications and drivers.

  • Can I remove photos from photos on the hard drive of my macbook, but keep them in iCloud?

    I just used icloud to "backup" 80 GB of photos that are on the hard drive of my macbook. I'm now able to remove them from my macbook without losing them on iCloud?

    All advice appreciated!

    Welcome to the Apple community.

    With iCloud library enabled, you cannot delete a photo on a device (or iCloud.com) without deleting each device which uses iCloud photo library (iCloud.com). In order to save space on your mobile devices (and indeed your Mac if you want to) turn on the optimization of the pictures on these devices (settings > photos & camera > optimize storage on your mobile device and Photo preferences > optimize storage on your Mac)

    Dynamic optimization, it reduces the resolution of your photos, if necessary, so that you don't notice it occurring initially. However, when necessary, it is very effective, and users have reported libraries being optimized for much less than 10% of their original size in some cases. My own library is about 9% of its original on my phone size.

    It does not start to the top, screen and hardware ok except belt disconnected.

    Hi Wally, the hard disk OS X and all of your files. Get a case for your reader, and it backs up. Try OWC

    Always keep your Mac backed up on an external drive with Time Machine or utility of cloning like SuperDuperor double clone.

    Try eBay for the adapter.
