Error code -43

I just installed Leopard and while everything else is checking out so far, trying to start Time Machine led to an "An unexpected error occurred - error code -43".

An ideas?

iMac (Intel), Mac OS X (10.4.10)

What type (Internal HD, External USB or FW, etc) & brand (WD, IoMega, Seagate, etc) and size of HD are you using with TM ?

How is the TM backup HD attached to your system ?

How did you format the HD and did you perform a single pass of writing zero during that operation ?

Is any data being written to the TM backup Volume and how long did it take ?

I got this error whenever the external drive, the one time machine thinks of as the backup, was disconnected. Even without starting time machine directly, when I first transferred files over from my western digital mybook, time machine assumed it was the backup and even asked to reformat it. (I'm switching back from windows and my drive format is ms-dos fat not mac os extended) I clicked no to the reformat/erase everything option without thinking about it any further. I didn't realize that TM took that drive as the backup and when it was unattached, that's when the error code started. I'd preferred it said "backup drive not attached" instead of "error code -43" but at least it didn't have that little bomb icon next to it!

To fix this, I went to the time machine preferences, by holding down the trackbutton over the tm icon and selecting preferences option that popped up.(right-clicking also works) From there I was able to designate what I wanted as a backup drive and what I didn't. that seems to have taken care of the error code -43 issue.
