Hi Mconn127,
I am not an expert in this field, just my experience offered.
Firstly, DO NOT FORMAT THE DRIVE!! (As your probably well aware) If windows ask you to do this when its plugged in then ignore.
The RAW filesystem is just a filesystem that is not recognized by Windows, so it cant access the disk and
as you found out your files are still intact..PHEW!!
I had the same problem a few years back when i just unplugged the USB HDD without "Safely removing Hardware device" first, and ended up with a RAW file system!!
Firstly try plugging the external HDD into a computer running Windows XP or Vista? Give that a try first if possible
and see if you can gain access to your data? With Windows XP theres a good chance you will gain access and can back-up your data and simply reformat the drive.(fingers crossed)
Failing that to try the next part you will need to discover exaclty type of external HDD it is? Make / model / aslo is it IDE, SATA and depending on which one it is, see if you are going to be able to connect it internally to your computer?
There is another way which doesnt involve opening the enclosure, but you risk losing your data and you do so at your own risk:

YOU DO THIS AT YOUR OWN RISK, IF UNSURE DO NOT ATTEMPT. (This following method also may not work)
The easiest fix for to access your drive, is to remove the drive from the enclosure and install it directly into your computer as almost any external drive can be used as an internal drive. (Ive done it plenty of times)
You will have to find a way to crack open the enclosure and remove the HDD. Hopefully just few screws and
easing the HDD out of the enclosure (Extreme caution advised). If you post the Make and model I will see if I can find a guide to do this.
Then once hooked into your computer, boot it up, (you may have to goto boot options and select the HDD that has windows installed), then from your desktop click:
Start > Computer and see if your drive has been recognised and that you have access, do not write to the disc at all, back up your data to another spare drive immediately.
If your drive is not listed in "Computer" please follow these instructions:
Start > type in search
manage at top click
Computer Management.
Then double left click on
Storage in the centre box.
Then double click on
Disk management.
You should hopefully see your newly installed "ex" external drive (if that makes sense)
If you can see your new drive it probably hasn't got a drive letter assigned to it?
If this is the case then right click
Change drive letter and paths then click
change and assign it a drive letter, click ok and exit.
Goto Computer and you should now see your drive and should be able to access your data? Again back-up immediately.
This method has worked for me.
Hope one of these methods helps you out, Good Luck
Cheers
Dave
