My mac tells me that " The disc in this drive can't be erased"

What can i do to delete whatever I have in a dvd... format it or whatever..if my mac tells me The disc in this drive can’t be erased.

Unless the DVD is a rewritable DVD, identified as DVD+RW or DVD-RW, you can't delete what's on it.

How do you repair the EFI systems partitions when you mac tells you that the live file system is not supported?

how do you repair the EFI systems partitions when you mac tells you that the live file system is not supported?

I don't have good news. You will need to repartition and reformat the hard drive in order to determine if the drive is still OK or if it needs to be replaced. If your computer is a 2011 model or later do the following:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.
If your computer is pre-2011 model, then locate the original installer discs that came with the computer. Then do this:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1. You can now download a version of OS X from which to upgrade from your Purchases page in the App Store.

How do I tell Win7 that the D (not system drive) is where my documents are?

I re-partitoned my disk. I now have one disk of 160 GB (C drive) where the System installed and where I plan to load applications/programs and one disk of 250 GB (D drive) where I plan to store my data.
But by default, the Users Directory is on the C drive, but all my data is on the D drive,. This impacts Library and a number of prgrams
Is there a way to tell the system that my default data is stored on the D drive?

Hi,
The programe should be installed in the system drive in order to work normally, the default location can not be changed, I am afraid.
By changing the default location of the user profile directories or program data folders to a volume other than the system volume, you cannot service your Windows installation. Any updates, fixes, or service packs cannot be applied to the installation.
We recommend that you do not change the location of the user profile directories or program data folders.
Using the ProgramData setting to redirect folders to a drive other than the system volume will block your ability to upgrade to future versions of Windows.

After Photoshop Elements quit working for the second time in three months, I uninstalled it and now cannot get it to reinstall from the disc. Nothing happens when I insert the disc. All I can do is look at the folders and files and see nothing that tells me how to start the installation. Clicking "open with Auto play" gives me irrelevant options, view photos, share, etc. I'm running Windows 8. This program has worked, although buggy, for the past year.

reinstall by clicking setup on your disk or downloading and installing,

Had hard drive renewed due to product recall (iMac) backed up complete system on time machine . Had the drive done got mac back tried to reinstall from time machine .The new drive tells me that the space has been taken up but can't find where the file have gone. Need to free up the space that the ghost file take up so I can drag drop from ex drive onto harddrive

Here's the scoop, new friend.....
When you boot into Time Machine you'll get the same OS X Utilities screen as you would if you booted into the Recovery HD. So, from there go into Disk Utilities to erase/format your internal drive. After that's done, back out to the OS X Utilities screen and select the restore option. Just follow the prompts to select the TM back up date you want to restore from and where to restore it to. Pretty straight forward.

My computer will not let me open itunes at all. It tells me that the itunes library can not be read because it was created by a newer version of itunes. What to do? Please Help Me.

My Computer will not let me open itunes at all. It tells me that the itunes libary can not be read because it was created by a newer version.

If you still have an issue you may have to see about using the iTunes version (application) included with Snow Leopard 10.6 from the installer or an another one if available online, and see if that will install.
Sometimes you may have uninstall the bits left in your system by the earlier (or later) iTunes installers; as they all leave a trace and these can stop a different version of iTunes from being installed.
Not sure if the following site/link will tell the method...

Whenever I go to iTunes with my iPod 5th generation 32 gb iPod Touch, running iOS 8.0.2, It tells me that the "Other" category is using up 14.59 gb of data. I have no clue why it says this and I have searched the internet for fixes and none worked.

Whenever I go to iTunes with my iPod 5th generation 32 gb iPod Touch, running iOS 8.0.2, It tells me that the "Other" category is using up 14.59 gb of data. I have no clue why it says this and I have searched the internet for fixes and none worked. I have tried on a windows and a mac and noticed no change. I have tried restoring to a backup but that didn't help. I haven't had time to do a full restore but I will try if the problem persists.

An "other" larger than about 1 1/2 GB indicates corrupted files.

Next, usually restoring from backup eliminated the corrupted files. However, sometimes restoring to factory settings/new iPod is required.

You are unfortunately out of luck with an Intel Mac and OS X 10.4.11<br />
Best would be to update to OS X 10.5 or later if you want to use Firefox 4 and later versions (current is 8.0).<br />
There is a Firefox 8 compatible third-party version TenFourFox from www.floodgap.com for a PowerPC Mac, but no alternative for an Intel Mac with Mac OS X 10.4.
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:

At the opening aperture often tell me that the library has to be repaired

at the opening aperture often tell me that the library has to be repaired

my external hard drive which are directly connected to my imac 27 inches with 16 gig of ram dissapear. Which cause a problem if aperture was running.
O.k., if your external hard drive is suddenly offline, while Aperture is still using it, and could not complete all database transactions, the Aperture will insist on repairing the library, just like after Force-quitting; this is necessary, for the Aperture library may be inconsistent, if Aperture could not finish writing its data.
This is not an Aperture problem, it is a problem of your external drive. It should not dismount while a program is using it. If it happens, while Aperture is running and the computer is going to sleep, change the energy saver settiings and don't let your mac go to sleep, while you need Aperture running. Ask in one of the technology forums, why your disk continuously will dismount.
I have recuperate my library with a vault on a 6 tb brand new in september and i can't get access to this new library i am now recuperate all the images by making copies of the master files . What a mess
Is that the same harddrive, or a second library? Can't you get access to your library after letting the repair go through?

I finished adding my transtions to my timeline. I was having crashing issues so I shut down everything before I rendered the project and now it tells me that the project is unreadable or the file is too new for this version of final cut. What Happened?

I finished adding my transtions to my timeline. I was having crashing issues so I shut down everything before I rendered the project and now it tells me that the project is unreadable or the file is too new for this version of final cut. What Happened?

What Happened?
No way for us to know. But if your system was crashing, there definitely was a problem. The FCE error message you got normally indicates the FCE project file has been corrupted. This probably happened due to whatever caused your system to crash & shutting down the system.
First, make sure your system is running correctly. Then, use the Finder to navigate to /users/yourusername/Documents/Final Cut Express Documents/Autosave Vault and find the most recent backup copy of your FCE project file. Copy the file to your Final Cut Express Documents folder (copy the file, don't just move it). Then double-click the copy to open it in FCE. It should open ok, but will probably not have your most recent edits (transitions). You may have to rebuild the transitions, but at least you will be back in action.
