OS X 10.8 time machine extremely slow, then stops working
after upgrading to Mountain Lion yesterday, I decided to erase & reformated my external HD to use with Time Machine in order to start fresh. It is the same HD I've used for Time Maching backups for the past 2 years and has worked flawlessly. However, when I started the Time Machine backup, it was painfully slow indicating that it was going to take 37 days to backup by 49 GB. I thought it might pickup speed after a while, but instead it just stopped working, displaying the message something to the effect that "no time machine drive was attached".
Anyone else having issues with Time Machine backups under Mountain Lion? Any suggestions"
Thanks.
