    I have Time Machine backing up to an external drive, connected by USB. 


    Today I noticed that my iMac doesn’t make time machine backups anymore. The backup starts but hangs after a while. It has to backup 2GB and stalls at a few hundred MB every time. 

    I find it very strange, this happens out of the blue. I never had problems with time machine before, is has been working reliable for years.

    I tried several things to solve the problem:
    • PRAM reset, didn't help
    • NVRAM reset, didn't help
    • unmounting my external HD, remove the time machine plist file, reboot iMac and mount the external HD again, didn't help
    • Check my external drive with disk utility, drive is OK
    • Check my internal drive with disk utility, drive is OK
    • I also tried time machine backup to another external drive, but this stalled also 
    Anyone a suggestion how I can solve this? Thanks in advance.

    Thank you, I found the same link in the Apple discussion forums. Right now I'm busy following the steps on that website :)
