Mac Error Code 0

It may make you wonder why any error code would have a 0 rather than a number to identify it. This is a good question that remains without an answer, but error code 0 does mean something in the world of Mac computers. The error message often says that the file cannot be copied or an unexpected error has occurred, code 0. This usually signifies that the file is too big to copy.

The Mac error code 0 is considered an unidentified error that typically occurs when transferring files that are bigger than 4GB to a FAT32 hard drive. The File Allocation Table (FAT) system is used on many computer file systems and memory cards as a way to organize data in a relatively simplistic way. It is commonly criticized because it is said to make poor use of disk space, which causes overloading. It is supported by almost all of the current operating systems, which makes it very versatile. Placing many files on a system that has a FAT32 system can cause the system to slow down and even crash.

A Mac has a file size limit of 4GB by design. This means that it is likely that you will receive an error message if the file that you are trying to download or copy is too large for the file system. Typically, this will occur when you are attempting to copy a large file to a disk that is in the FAT32 or MS-DOS format. These systems are not equipped to accommodate files that are larger than 4GB, even if there is enough space on the drive to do so.

If you are trying to copy a file of 4GB or larger, you will need to reformat the hard drive to accommodate the size of the file. You can reformat your hard drive by:

• Backup all of your files before attempting reformatting.
• Open the Disk Utility from /Applications/Utilities/Disk Utility.
• Double click on the Disk Utility program to bring up a list of all of the drives available on the computer.
• Choose the name of your hard disk by highlighting it.
• Select the Erase tab. This will display the options for erasing the hard drive and reformatting it to work on the Mac.
• From the Volume Format menu you will choose Mac OS Extended. It is also recommended that you name your hard drive.
• Click the Erase button and then click Erase again to confirm this is what you want to do.
• Once the erase function has finished, quit out of Disk Utility and then you can reload any data you have backed up from your backup copy.

Reformatting your drive should both eliminate the Mac error 0 and allow you to have more space on your hard drive.

Kernel Panic in Mac OS X

A kernel panic is a term specific to UNIX operating systems, such as Mac OS X, and it is the equivalent to the term bug check in the Windows world. It panic is the action taken when an internal fatal error is detected by the system. A kernel panic is designed by the operating system to react by sending out an error when something goes wrong.

If you receive a kernel panic error message that says you need to restart your computer, or that your Mac won’t start up in Mac OS X, the first thing you should do is restart your system to see if the same error remains when you boot back up. Basically, when a kernel panic occurs, there has been a system crash in Mac OS X. The computer system responds to the panic by doing one of two things: waiting for the system to be manually rebooted or initiating an automatic reboot.

There are several reasons why a kernel panic occurs. The information provided with a kernel panic is often very technical, and it has the goal of assisting a system administrator in diagnosing a computer problem. Some of the causes of kernel panics may require technical assistance beyond that of the average user. Listed below are a few of the causes and how to go about resolving them.

Defective or incompatible RAM or lack of hard disk space or RAM

This is the most frequent cause of a kernel panic error. You can first try to defragment your system and clean up your hard drive to get more available memory. In the Applications directory, open the Utilities folder and then open the Disc Utility Program. Select the drive you want to defragment by highlighting this drive from the list available. This process may take some time so plan to do this during a time when you will not need your computer, overnight for instance.

Defragmenting may work for the short term, but the best way to resolve a RAM issue over the long term is to purchase more RAM. Memory can easily be purchased through a computer store, and either you or a computer technician can install it. It is important to ensure that the RAM is compatible with Mac OS X.

Incompatible, or corrupted kernel extensions, or drivers

Third party hardware that is outdated or programs that are incompatible with the Mac OS X system being used can cause a kernel panic error. Ensure that the software and hardware that you are using is compatible with your Mac OS X system. This should be listed in the software documentation that you have. If you find you are using something that is not compatible, you should remove it and install something that is compatible. You can also check the website of the applications you are using and download or agree to updates as they are available. Most software prompts you periodically to search for updates. If you know that your software is compatible, keeping it up to date is the best way to avoid kernel panics.

Hard disk corruption

When there is a problem with your hard disk, it will often result in the freezing of your computer or your computer running slowly. If freezing occurs, it is a sure sign of trouble internally. In this case, you will want to obtain assistance from a professional to repair your corrupted hard disk.
