Slow backup?

I've switched over to a new compuer and I'm not able to complete a backup. Last night I plugged the iPad in and 6 hours later, it still shows 'Sync in Progress' and iTunes is still on step 1 of 3 (Backing up).

The only thing I've found is to shut off the backup on the Zinio app. I've done that, but get the same response.

I've cancelled the back up and the sync continues, but then I get a message that the iPad is disconnected and the back up does not complete.

I want to be ready for the iOS 4.2 update and need to get this solved!
Any options??

(Also, the iPad shows 'Not Charging' when I'm attempting the sync, is this normal?)

 

Seriously… no one else is having this issue? Just connected my iPad this morning and after 1 hour it’s just 25% through the backup. There has to be some options. (Capacity: 59.17 GB w/18.1 GB free)

 

The port should be ok. I'm running tests on it now. (It's a year-old box with a EVGA 141-BL-E757-TR motherboard)

But I just hooked my iPhone up to it this morning (Capacity: 29.06 GB w/13.0 GB free) and the backup took less than a minute.
