Lion not recognizing external HDD

[mat25]

I just did a clean install of Lion, and my Western Digital My Book Studio LX (FW 800), is not being recognized by my iMac. Disk utilities is not also not seeing it, even after a reboot. This drive contains all my time machine machine back up data, and is therefore very important. Any help is greatly appreciated!

Mods, you can delete this thread. I unplugged the HDD, and switched the firewire ports on the back, which seemed to do the trick, sorry for the thread.

Same trouble here!

Hey, I'm having the same issue. Mine is a 1TB Western Digital MyBook.

Lion isn't mounting the drive and I'm not seeing it on the desktop although it's connected. The strange thing is that actually I can see it on DiskUtility but I can't do anything with it.

Please help! I need to access my files.
