In this article we will see how to resolve error 43 that may occur when using Apple applications, such as Time Machine and QuickTime.
Error 43 when using Time Machine
You may receive the following error while backing up of your Mac system using Time Machine:
“Error -43: a file could not be foundâ€
Cause of the Error
The error occurs because Time Machine is unable to locate the Time Machine drive. The following reasons may prevent Time Machine from locating the Time Machine hard drive:
- Time machine settings are not pointing to correct external drive.
- Time Machine preference files are corrupt.
- Time Machine drive is corrupt.
Solution
The following fixes may help you in resolving the above error:
- Reselect your backup drive
To reselect the Time Machine drive, first remove the selected backup drive from Time Machine system Preferences and turn off the Time Machine. Now, turn the Time Machine on and reselect the Time Machine drive.
- Remove the Time Machine preferences
In case the Time Machine preferences file is corrupt, Time Machine may be unable to locate the backup drive. The Time Machine preferences are saved as com.apple.TimeMachine.plist and are typically located in the /Macintosh HD/Library/Preferences/ folder.
- Repair the Time Machine drive
If your Time Machine drive is corrupt, Time Machine will not be able to work properly. Use the Disk Utility or a reliable third-party Disk Maintenance tool for Mac computers to repair the faulty drive. In case the Time Machine drive is damaged beyond repair, then format your Time Machine drive to resolve the issue.
Error 43 when using QuickTime
The following error is generated when QuickTime is unable to locate the file you are trying to open:
“Error -43: a file could not be foundâ€
Cause
Generally, the error occurs when QuickTime is unable to recognize the drive on which the file you are trying to access is saved.
Solution
Open the disk management and check whether the drive on which the file is saved is named correctly or not. If the drive is named incorrectly then QuickTime will not be able to access the files saved on it. For instance, if your F: drive is named twice, as (F:) (F:), QuickTime will not be able to recognize the F drive; thus, will not be able to play files stored on this drive.
To rectify the issue, change the name of the drive to correct format, which in this instance means you will need to change it to a single (F:).
If your QuickTime is unable to play files from an external drive, such as an NAS drive, you can copy your files on any of your internal drive and play the files from there.
You can minimize hard disk-related errors, such as Error 43 by ensuring your hard disk stays in good health. One major cause behind hard disk corruption is malware infection. We recommend you install advanced and easy-to-use antimalware tools and schedule regular virus/malware scans of your entire system.
