Do you have a 622 or 722. Interestingly, I have one brand of external enclosure that seems to work fine on the 722, but experiences errors like yours on the 622.
I have 2 suggestions:
First, once you get an error like this, I would reboot the 622/722 before trying another drive.
Second, go get a Linux stand-alone boot cd and use it to run a check disk on the drive. The file structures are probably broken.
here's the command I like to use (from a terminal):
sudo e2fsck -f -C 0 /dev/sdl1
sudo e2fsck -f -C 0 /dev/sdl2
sudo e2fsck -f -C 0 /dev/sdl3
Your device will be different, but a 750 gigger will have 3 partitions. Use the Partition editor to figure out the device. Close the partition editor and unmount the drive before running e2fsck.

Sometimes I have found missing programs in the "lost and fount" folder after the repair. It is possible to move them back, should you'll need to make yourself root to do this. Make the folder structure look the same.

Thanks for your response. First, I did several reboots of the 622. Second, I am very confused as to your other instructions. I am not familiar with the Linux stand-alone disc and what it is or where to get it. Since I am not familiar with it and the other instructions are a little too high tech for me (I am an expert at audio video but not so much with computers) that I am afraid of doing something to the contents of the drives.
It seems strange to me that all 3 drives, at the same time, would have trouble beginning at the same time after working so well for almost a year. I called Dish and they are sending me another 622 as they felt something might be wrong with the 622 UBS port that I have since all 3 started having trouble. I am wondering, after reading your post, if I should instead get a 722!
Here is what is happening.
I plug in one drive, and it shows that I have connected a drive, and then go to view its contents. It works fine but sometime during the movies on it, it freezes and I can't do anything with my remote, the movie frame is frozen on the screen. After a few minutes of pressing "stop" the 622 goes back to the TV signal. Then I try and hook up the other 2 drives and both say "You have connected a device that is unsupported by Dish Network." This varies, one day it's one thing, the next day it is another. One day it reads one drive, the next day it will read all 3 drives, the next day a movie starts and freezes after 5 minutes or 60 minutes, it's never the same.
I have spent the last year and a half recording my favorite movies in high def. I hate to lose what I have taped. Do you all think I should try a 722? None of this makes sense as one day it reads the drives, the next day there's problems, could it be a bad 622 USB input or something?
I have a new 622 coming (called today, but it's Sunday and I can still call them to change it to a 722 and just pay the extra). What do you guys recommend? I am using Seagate Freeagents, one 750gb pro model and 2 500gb regular models. I am very afraid I don't understand your directions with the Linux disc and almost sure I would screw it up.
