Burnt discs full of static

When I burn discs with iTunes, I find that nearly always the later songs start filling up with static, until they are almost completely full of it. This usually kicks in around the 8th/9th/10th track on each CD.
Can anyone suggest what kinds of things might be an issue? I realise faulty media (I'm using Sony Imation - they're usually pretty good) is one possibility. But are there any hardware issues as well - could my burner be damaged or faulty?

I have experienced the same issue. It became serious enough that I had the Apple store replace the superdrive. All the music in my iTunes folder is Apple Lossless encoded. The discs I burn are audio discs. The blank discs have a nominal capacity of 700MB. After some in-home analysis, here is what I've found:
1. I fed one of the malfunctioning discs into my Mac, and info'd it. The info window showed that the disc had 772MB stored on it. Well, that's not possible, so I got to thinking about it.
2. When I was burning discs, I was only looking at the total time of each playlist. If the playlist was less than 80 minutes (the maximum capacity of the blank discs), iTunes would burn the disc.
3. Problem is, a playlist can be less than 80 minutes but when the Apple Lossless-encoded songs are expanded for a burn to an audio CD, the total size may exceed 700MB.
4. My opinion is that there is a bug in the iTunes software; that is, it allows us to burn a playlist to an audio CD even if the playlist will exceed the nominal capacity of the CD after the compressed files are expanded.
5. There ought to be a function in iTunes that allows a user to determine the expanded size of a compressed playlist, to determine if it will actually fit onto a blank CD. Simply referencing the playlist duration doesn't help.
This obviously begs the questions: by what process is iTunes burning a playlist to a blank CD when the expanded playlist exceeds 700MB? And how can the CD, once it's burnt, display >700MB when you insert it into the Mac's drive and check its stats? And why does iTunes allow burns when the size of the expanded playlist exceeds 700MB?
Any help is greatly appreciated.

Start up disc full, tried everything I can find, no changes, help?

I posted this somewhere earlier, sorry for repeating, but I can't find it. AFter getting the start up disc full message, I backed up everything on an external hard drive with Time Machine, and additionally, copied everything from iphoto on to the same drive, different partition. I have freed up tons of memory, but no change to the start up disc when I check it in the activity monitor area. I have restarted it a number of times, emptied all trash, and checked the console log for messages. I see lots of "failed to count the number of files in the "/system/library/memory/startupItems": No such directory. Other than that, nothing popped out at me. I also ran the diagnostics for the disc and repaired all permission scripts, (I think that's what it said) no help.
I am grateful for any help, could it be a virus or an error I can't detect?
Thanks,
Veronica

Would that have worked if I had tried it before the "archive and install"? Because that is what I tried next and it didn't work, and I'm just wondering if it didn't work BECAUSE I tried to do the Archive and Install first? Or if it just never would've worked because my hard drive's messed up?
I'm just wondering because after I got the last response, I called Apple Care to see if there was ANYthing else I could do before having to either erase everything or actually haul it down to the Apple store, and it's the Apple care guy who told me to try the Archive and Restore first. So I'm just a bit annoyed if this could've been avoided by simply doing a new install first, if it's the Archive and Install that ruined everything...

I have PSE-12 on Mac. Got message "scratch disc full" tried changing drive to backup disc. Now PSE-12 will not open to allow me to go back to original drive. What can I do?

Using PSE-12 on my Mac and got the message 'scratch disc full' I have backup disc attached to computer and tried making this the number 1 disc. I now can't get PSE-12 to open so that I can get back and reverse the order of these discs. What can I do?

Go to your username>library>preferences and delete:
com.adobe.PhotoshopElements.plist
Adobe Photoshop Elements 12 paths
Adobe Photoshop Elemetns 12 settings
and any lockfiles with the same names. That library is hidden in 10.7 and up. To see it, click the Go menu in the finder and hold down the Option key and it will appear below the little house for your user account. While you're in there go to the saved application states folder and delete any for PSE.

I keep getting the message "macintosh hd disc full" when I try to edit or import video. How can I make room?

You can go to Applications, Utilities, Activiy Monitor to see just how much space is available. To free space you need to remove files that take a lot of space, things like videos, photos, music. Get an external hard drive, OWC http://www.macsales.com has a good selection, and move material off the internal drive.

Scratch Disc Full: Where are the temp files kept?

Hi,
I just tried to open a few of very large image files (9GB in total) and when I did I got the message "scratch discs full". Now I understand why that happened, but it seems to have eaten a whole load of disc space that wont come back. I've since closed photoshop, restarted my Mac, etc. but about 10 GB is still used up where it wasn't before. I can't locate any temp files anywhere (prefs only tells me the scratch disc is my Mac HD, not which folders it's in). Can anyone help me with this? Where are Ps temp files usually located on a Mac? I need those 10GB back!
Mac OSX running Photoshop CS3
Thank you!

Hi again Chris (or anyone else who cares to contribute),
My Mac's HD space continued to disappear and I have now, finally, located the cause (I think). I checked the system log (Stystem Profiler/Software/Logs/system.log) which was itself 4.5 GB in size (too large I think?). However, when I went to the file location (/var/log/system.log) I also noticed that the "asl" folder (in the same folder as the system log) was 20 GB in size!! Having read a few forum posts about similar issues, I took the risk of deleting both the system.log and the majority of files in the asl folder. This seems to have worked a treat (I now have 25GB returned to me).
As I said in my original post, this all started happening when I opened a few very big Photoshop docs (ones with layers). Do you have any idea what caused / is causing this to happen? I haven't opened Photoshop since deleting the asl files, but new ones still seem to be appearing in the asl folder. They are tiny (100KB at most) but I'm a little concerned I haven't fixed the problem. Any suggestions?
I can't see why new asl files would be appearing when I haven't even opened Photoshop.
I'm running on OS 10.5.8
Many thanks,
Matt
P.S. By the way, the size of the system.log seemed to be caused by a repeated message regarding RealPlayer, which I assume is unconnected, but I have included it below just in case (I've removed RealPlayer from my Mac to see if that helps, but the asl files still seem to be appearing):
Jul 28 18:16:07 localhost RealPlayer Downloader[299]: Failed to create window context device

Speaker mode is full of static during calls

My iphone 6 iOS8.0.3 has speaker phone problems. When the phone is in speaker mode and this is only during phone calls, the sound is full of static. This also occurs when my phone is in bluetooth mode during calls. I can play music just fine. Weird.

I went to the Apple Store and they reset the firmware and restored the phone as well. I am still having the issues. They said the phone was fine and to keep using it for a week. If there were still issues then to come back and they would run another test to see if the phone was picking up any issues with the reception. The guy that helped me said that his phone sometimes has an echo for a couple of days and then it goes away. I am wondering if it is a problem with Rogers. I am interested to see that you are having similar issues. The static when it comes is a little annoying. It must be a software issue.

IPhoto Blank Disc is getting Disc Full

When I put in a blank CD, iPhoto sees it but then says "Disc Full",
other can can burn CDs off this same machine, so its an iPhoto or a firmware issue,
Any help would be greatly appreciated,

Download and start using OmniDiskSweeper. It will tell you the folders and files that are taking up the most disk space.
Anything in your Home folder is a good candidate for deletion or movement to an external disk.

OS X says boot disc full when it isn't - by a long way

I ran SuperDuper last night and the backup failed with an unknown error. After, Spotlight didn't find files. I rebooted and at the login screen was given the error message 'backup disc full, delete some files' - problem is, OS X won't boot beyond the starfield screen, so there's no way of deleting files or running the system. I took the drive out and put it in a USB caddy on another machine and ran Disk Utility - it said repairs were needed, so I did this. However, putting it back into the MBP nothing has changed, it still won't boot and insists the disc is full - there is over 180GB free! (I can see this when I mount it on another machine.) Ideas?!

Thanks guys.. This is sorted.. I guess i missed a right parenthesis in FROM
Cheers

Disc full, disc full

Hi all,
I have 750 gb mac book pro.
The message is "disc full". In fact I have used 450 gb and do not understand where are the rest 300 gb. Any help?
It is happened with the IPad too - there are some " other files" after usage of 1 month of the device that keep a good share from the capacity. Then I restore the Ipad and these selfarising files disapesred. Can I restore some how the mac book too ?

The important value at this impoint is not how much is used, but how much free space you have. If you have less than 1GB, you have an urgent problem, which you need to solve right away.
Get a couple of 8MB thumb drives, boot in Safe mode (which clears some caches, and thus gives you a bit more space), and archive or delete items from your Home folder (only from your Home folder). You can also archive and delete apps you don't use. You need to have at least ~5GB free to work with (if you want to use Finder to archive data to DVDs, you need at least ~10GB to be on the safe side). Once you do that, you can reboot and start investigating with ODS or similar utilities where your disk space has gone and how to manage it.
I would suggest that the OP use a couple of 8GB thumb drives, 8MB won't get rid of much.

New memory card installed but getting 'Start up disc full' message?

Running on an old Power Mac G4, 256 MB, I have recently got a new ipod and began filling my itunes when I get a 'start up disc full' message. I've successfully installed another identical 256 MB memory card which the computer is recognizing (now showing 512 MBs of memory) but after downloading another 1 or 2 CDs I'm back to 'start up disc full'. I know I have the correct memory card for my G4 but it isn't allowing me more memory. Any suggestions? Do I have to change something that isn't in my owners manual?

Hi-
Welcome to Discussions!
You need more hard drive space. Although replacing the internal with another, larger drive is an option, it is easy to just add another drive. The G4, any model, can use up to 4 internal drives.
Some have size limits, so you need to tell us your G4 model. Use the "About this Mac" in the Apple menu on your desktop, and the following to ID your model:
http://docs.info.apple.com/article.html?artnum=58418
Another option is to buy an external firewire hard drive, so you can backup, and store files on it, freeing up space on your strtup drive. You really should have an external, anyways, so you have a backup, and don't lose any data if there is a problem.
Adding a hard drive is relatively easy. You can find Do It Yourself guides in the following:

RE: Start-up disc full!

I am receiving msg. "start up disc full" and am unable to do updates, download i-tune purchases, etc.... I went into finder and did the command i on "library". Looks like this is my problem. Any suggestions on how to clean it out? Thx!

If you are talking about the Library folder (or the System Library folder) at the root level of your hard drive, DO NOT delete anything in it.
Your best bet is to move some of your content files to an external drive. Items like your iTunes and iPhoto libraries are likely to be largest. Here is how to do it:
Copy the library in question (the iTunes library is located in your Music folder, iPhoto can be found in your Pictures folder) to an external hard drive.
Launch the application while holding down the option key on your keyboard.
In the resulting dialog, select the library on your external drive.
Test to make sure the copied files are functioning normally. If they are,
Move the old library to the Trash and empty the Trash to reclaim that disk space.
Best of luck.

Just in case it's an iPhoto problem suggest that you also cross-post in one of the iPhoto Forums where the iPhoto users hang out. Hopefully, someone will see your post & respond.

I am getting disc full messages on my Mac, unable to empty trash because not enough space, how do I proceed or do I need to increase my 4gig of memory

I am getting disc full messages on my Mac, unable to empty trash because not enough space, how do I proceed or do I need to increase my 4gig of memory in which case how do I go about this process.

You are confusing RAM (Random Access Memory) with hard drive data storage space.
Your hard drive storage is getting too full if you can't empty your Mac's main trash.
Here are some general tips to keep your Mac's hard drive trim and slim as possible
You should never, EVER let a conputer hard drive get completely full, EVER
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your Mac's Trash icon in the Dock?
( as you mentioned, you can't empty this as your hard drive is too full.)
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
To find other large files, download an app called Omni Disk Sweeper.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Macbook Air - disc full message even after cleaning

I got the disc full message so I saved everything on to a flash drive and deleted every video, picture, and word document that I've ever created. Also some application I do not use. My computer was acting slower around the time I got the original 'disc full' message. After clearing everything off, including itunes. My computer was still running slow, with long loading times online. I downloaded the new Maverick operating system and my computer is running back at normal speed. However, I can only save a few documents before I get that same 'disc full' message. I checked my 'about this mac' and under storage it says there is a total of 3.3GB free out of 120.47GB.
I'm no computer expert, but shouldnt I have memory at least to save a bunch of documents?
I'm a student and I'm always saving notes, word docs, pictures for power point. I need this extra room asap. flashdrives are nice but I can work more efficient with my flashdrive cooperating.
Can some one please help me out?

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.
