Time Machine error code -43

When I upgraded to Leopard a few weeks ago I was able to open up Time Machine. I didn't activate it, though, because I didn't have the hard drive available. I bought a new hard drive today and tried to activate Time Machine. I received this error message:

The operation could not be completed. An unexpected error occurred (error code -43).

This happens every time I've tried to open Time Machine. I've tried rebooting, but that doesn't help. Any ideas?

MacBook Pro, Mac OS X (10.5.1)

What type/brand of Hard Drive? Most drives come formated for non Mac systems (Master Boot Record).

you need to go into Applications:Utilities: and run dusk utility. the drive will show up on the left pane.
click the top of the 2 listings (the one with the size in GB). There will be 5 buttons on top of right side window (First Aid, Erase, Partition, RAID and Restore. choose partition.

Under Volume Scheme, change current to 1. Name the drive using ONLY alpha/numeric characters, no spaces. in bottom of window, click Options button. If you have a Power PC Machine, choose Apple Partition Map, For INtel based Mac, choose GUID Partition. click apply, wait a few minutes and you should be all set. Time Machine will now be able to use this drive as a backup drive.

Leave a few hours for time machine to do its initial backup. after that backups should only take a minute or 2, depending on how much your files change.

good luck and enjoy

The thing is -- I get there error as soon as I try to open Time Machine -- it doesn't know yet that I want to use the new hard disk.

The new disk is a Lacie 1TB big disk extreme+

I stumbled on to the answer...I was in System Preferences to do something else and saw the Time Machine icon. I opened that one up and was able to change the drive...it was pointing to my FAT32 drive instead of the new drive.

I also had the same problem with the -43 error while trying to use Time Machine. Booting in single user mode and running fsck did not find any problem, nor did Disk Utility find anything wrong. I have been using my WesternDigitial USB portable hard drive since receiving my new iMac in December with TimeMachine. I had, on occasion restored some documents, with no trouble at all. I let my guard down and decided to depend solely on TimeMachine to back up my system.

A couple of days ago, I noticed that TimeMachine is not backing up anything (I was used to seeing activity on the drive daily). I attempted to initiate a backup manually to see what was going on, and immediately received the -43 error. My entire backup became useless, because I could not restore it.

This was very aggravating, as I had several things that could not be recovered. I think it would be best practice to have redundancy in your backups, instead of depending solely on TimeMachine.
