MicroSD Card question on rooted device

[PaseMkr]

Hi all,

I have my Xoom rooted, running stock 3.1 and Tiamat kernel 1.4.4. I was interested in learning how to do a Nandroid backup for the first time as I am new to rooting. So I Googled Nandroid Backup to learn what it was and how to do it. From what I read it said that I should backup the SD card before I perform a Nandroid backup so that I don't lose anything from the card. I took the MicroSD card out and put it in a card reader for my PC and it was empty. I saw no folders on it or anything, except for the last Tiamat zip file that was on it from my last kernel update. The thing is, when I put it in the Xoom and look at it through Androzip, it has folders such as DCIM, Download, Music, Pictures, TitaniumBackup, etc, etc. This is confusing my as to why I can only see these folders on the Xoom, but not when the card is in the PC. If this is normal, how do I make a backup of the MicroSD card?

See if this makes sense.

Also take a look at this, you should be using this recovery.

ggrant, but what about the SD card question regarding why I see folders on it through the Xoom, but not when it is plugged into the PC?

The Xoom shows its internal storage as /sdcard, your actual sdcard should show as /external. You need to put all your media on the actual sdcard so when you back it up the file isn't quite so big.
