Anybody tried this using a pen drive and no external power? How about mounting another Android phone's Sd card?

I'm curious. Does anybody know the output current on that port? If it's 600mA as has been said that's sufficient to power some 2.5" and 1.8" "passport" HDDs.

If you try your phone card, back it up first. I am not sure which action wiped my phone's microSD card, but it's now blank. :( It only had apps on there, no real data so I can just take the time to put them back on.. but....

Here are the steps i was playing with and I am not sure which one wiped it.

1. Inserted card in to microSD card adapter to check which file system it was (FAT or NTFS.. it was FAT32
2. When windows read it, it said it was not formatted properly and asked if I wanted to. I said 'NO'.
3. Then tried it in the MicroSD slot of the Xoom (for grins and giggles.. nothing)
4. Then accessed it through the host cable - didn't see anything on the drive so I thought it wasn't reading it properly.
5. Put it back in my phone.. phone said it was a blank card. :(

Oh well.. life moves on and another lessoned learned the hard way. The downside of experimenting.

Also, I tried a Toshiba 500G external drive (has only 1 miniUSB port but came with a dualUSB y-split port cable.. one for transferring and one for charging)... and the xoom didn't see any of the files on it. So I think it needed more power.. but I didn't go further as this one wasn't backed up yet and I didn't want to test my luck after the microSD incident. :)

None of those stages if you performed them as you say should have wiped it. If ou need anything back use a linux box to recover the partition because it's unlikely the data was lost just the table.

I said it puts out about 600, because I hooked up my evo and charged it. These are the numbers, but remember the evo uses about 50-100 to stay idle.

Thanks for the numbers. They would suggest there is certainly enough juice there to power certain of the USB powered HDDs, it just depends if it can maintain the current at voltage required.

Does anybody have a smaller 1.8" portable hdd they can try?

The standard 500mA devices are probably pushing it near its limit.

Thanks, don't have a linux box around, but will see if I can figure out any other options. Maybe I can load a virtual box or an emulator in windows. I am not a linux guy so just throwing those out there. But thanks, I will do some research.

In that case, try out the freeware Windows tool "Recuva" I believe it's made by Pirifom, and please accept my apologies, sometimes I forget that Linux isn't everyone's cup of tea.

No worries.. I don't mind trying. I took a class a few years ago for Unix administration for fun... just haven't had a need for it since then so lost the know-how. Will check out Recuva. Thanks.

Powered only by the xoom? Or using dual power with a plug for the drive? I guess its going to be hit or miss depending on drive requirements.
Xoom power only. No hub, just straight connection (through the eBay cable). In fact the powered one i have just keep reb00ting my xoom when i tried it.

I would like this hack to be merged with tiamat kernel's baseline because that way it would a one stop shop and be able to download a package where you can get all the capabilities with one kernel.

I just saw this thread. Does this mod still work on the current kernels? This will definitely allow me to replace my laptop with my Xoom.

Yes it does. I just "installed" it yesterday and my 250GB NTFS HDD is recognized and movies play nicely. Make sure you scan the referenced thread on slatedroid.com for the correct file. If you can't find it I attached the one I d/led yesterday. Hope the OP doesn't mind! Also, follow the script instructions. I used Gscript lite and saved the mount and unmount script so they're available with one click.

Wait is this for 3G only or will this work for WiFi also. I'm about to do it but all of a sudden I blanked out and didn't know where to begin. I'm trying to find the thread on slatedroid.com but the search results turn up random stuff relating to ntfs.

Could someone post a link from ebay or even amazon for the cable?
Just go to Amazon and search for "micro USB to female". There are two nice ones that won't have to ship from China and no dangling cable as it's just a one-piece adaptor.
