USB problem
I didn't like Lion, so I tried to downgrade it to Snow Leopard. I started with copying my libraries, music, photos and everyting I needed to USB External HD. Than I format whole Macintosh partition and installed Snow Leopard from DVD provided to my macbook. Obviousely I've lost everything on Mac's HD. I thought it won't be any problems, but now I can't get my data from external HD. I don't want to install Lion again.
Unfortunatelly I don't have Time Machine.
I've already used option "Repair" in Recovery HD. Doesn't work. I've got a message: "Device appears to work properly" or sth like that.

Actually I really don't know what does this everytnig mean. But if it's necessary for you, so maybe you'll find a source of problem.
I'm not a big IT person, so it's not easy for me to check terminal and whole this stuff. Please take it into account when repling me.

Thank you again and I still ask you for help.
Greetings.
That's a normal format type for Mac OS. Windows won't see it without additional software.
I guess the first thing I would do is run Disk Utility Repair Disk. There shouldn't be anything different between Lion and Snow Leopard, as far as format is concerned.
If you can, do the following command in Terminal, both while booted to Recovery HD (which would be running Lion), and while booted in 10.6.8. Post the results, labeling which was which.
You should see something like this:
Code:
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *750.2 GB disk1
1: EFI 209.7 MB disk1s1
2: Apple_HFS HG Wells 749.8 GB disk1s2
This is actually my Time Machine drive, the same one I had been using with 10.6. It's FW800, not USB.
If Lion is
installed on a device, it will create the hidden partition Recovery HD. After reading yours and the OP, I restarted on a 10.6.8 partition and plugged in a USB stick that I had installed the Recovery HD partition on. It worked fine, i.e. the Recovery HD partition remained hidden and the rest mounted normally (I had partitioned it into 1GB and 7GB partitions. I used Lion Recovery Disc tool to install Recovery HD onto the 1GB partition.) This hidden partition should be the only unique difference between Lion and Snow Leopard, and
only on a drive that has had Lion installed on. So, your USB drive should be just a plain vanilla Mac OS formatted drive, which should work fine on any OS-X system back to at least 10.2.
I don't know what I'll find, if anything, in looking at your partition lists, but I'll certainly take a close look.

May you suggest something to solve this problem?
Does solution even exist?
I know exactly what's going on.
Lion does some monkeying with the file system on Time Machine drives, in order to enable its Versions and Auto Save features. These changes render such file systems incompatible with earlier versions of Mac OS X.
