For HDR photos you need to make multiple shots, with that you don't use Extended bracketing but Exposure bracketing so the button on the left side of your view finder.

With Extended bracketing the camera record 3 jpgs with differend settings for saturation, sharpness, contrast or white balance. With RAW file those values aren't lock in the file like with Jpg so you can change them without hurting the image quality.

This a good site to start with link
The first tutorial is very good link I started myself with this one

Had the same problem also once by unplugging the drive while i was transfering files. simply scan your disk for errors, it's done in 30secs and will restore/repair the links.

I think you're looking for something like this link

Ah okay but can't you set them on a VPN and access them like that, I've no idea how they work but that might be a solution I think or not?

The only thing that I don't like about the WD is this link

He states that it was in Rec. Mode, not on the back of the camera.

Glad you got it sorted Rbubbly. [/quote]Yep I stand corrected and also too Ross
I was somewhere else with my head

But rbubbly, it might be better just to use RAW instead of using Extended Bracket, it gives you far more option and you can adjust those things far more prciesly and indefinently if you keep saving it in a RAW file

He means the exposure bracketing button on the left side of the viewfinder, press that and keep it press and you see in the top LCD the bracketing values, you can chance the exposure spacing with the front E-dial and the number of shots (3 or 5) with the back E-dial.

Guys he means the Extended Bracket not the Exposure Bracketing
The Extended Bracket only works with JPG and not with RAW, that is the problem I believe.
If you shoot in RAW, Extended Bracket is useless since the saturation, sharpness, contrast and white balance can be adjusted on the computer without any quality lost.

You can look at the back of your computer to se if you've the connection, that's the easiest way. they look like this link

This drive also comes with esata but it it lacks the Firewire 800 but it still does have the 400 and usb2 link
You can also save just a bit more and get this one link

this is an artical of 1,5 years ago of the previous models but you get an idea on how they preform link

Reviews of the new drives;
Lacie d2 Quadra
Western Digital My Book Home Edition (studio edition is almost the same except the firewire 800 so far as i can find out)

edit
Extra tip, convert the hard disk to NFTS if you use Windows that way it's easier to recover any data when something goes wronf or accidently delete something

btw why are there 3 topics running over external harddisk now?

Nope those are networkdrives link
With those you can also plug in an extra external harddisk.
What do you mean with crippled, Shim?

The WD My Book Essential link turns itself on and off with your computer. The home editions link goes into standby after 10 mintues of no use.

Sorry it seems like I'm really promoting Western Digital here but I only have a My Passport so I've no idea how the My books are in use.

Western Digitals are quite lovely, here are the variations link
I myself have a small 2.5" drive that only needs a usb conection and doesn't need extra power cord or anything. They also go up to 500gb and are very portable although more expensive link
