    I have a WD 1TB external drive, and I use it as time machine, which format is mac os extended(journaled), and it works great in SL, but when I updated to Lion, and the first time I tried to do a time machine backup, the window popped up and tells me that I can only read the hard drive, and now I can not even mount it! My Lion can not mount mac os extended format, I want to know what's going on? And I did a disk repair and still, tells me I can only read..

    Anybody, please help.. The drive is 1TB,and I've used 600GB of it, I can not erase it

    Have you checked with Disk Warrior of another third party disk utility?

    Disk Warrior did the work, I'm so happy that it saved my 600GB files. But I do hope Apple can improve this time machine thing's stability, cause the disk warrior cost me 100 dollars.....That's a lot:mad:

    I'm noticing that my WD 1tb drive does not show up in finder immediately after plugging it in. Sometimes, it can take a few minutes. This behavior only started after upgrading to Lion
