Expandable Storage via microSD

Microsoft supports expandable storage on Windows Phone 7 devices. If an OEM chooses to do so, it can implement a microSD card slot for additional storage. This is similar to what Google allows with Android, however the similarity ends here.

Windows Phone creates a JBOD span across your internal NAND and any NAND on microSD. It’s all treated as one contiguous address space, like a large hard drive or SSD. The benefit is you don’t have to manage where you put your apps, music, movies or photos. The downside is you can’t just remove/replace the microSD card in your phone.

The OS is obviously stored in a known location, however data is written linearly across both internal and microSD NAND. Your phone will still boot if you remove or swap out the microSD card, but you’ll be greeted with an error.

If you remove the card and attempt to read off of it on your Mac/PC you’ll quickly realize that you can’t. By removing the card you effectively break the file system. Microsoft provides you with a couple of other options to get data to/from the phone (which I’ll get to later) so you don’t have to rely on swapping microSDs.

You aren’t stuck with that original microSD card however. If you do a factory restore with a new microSD card installed the OS will format across it and you’ll be good to go. Obviously you’ll have to re-download all of your apps and sync all of your files but it does work.

    Am I the only one who sees that the "brown" option for the UI color is red? Am I losing my sight? My tv is adjusted perfectly to THX standards. All the other colors look right. Or is it just the camera you used to take the shot?

    As far as I'm concerned any phone that doesn't have a "fine me" feature with the ability to lock it doesn't even exist. Seriously, why has it taken SOOO long to have this? It should be standard on all phones. Now I want to be able to make my phone the key for my car.

    I'm the same as your dad. I mean I want to view everything is the proper aspect ratio; but I also REALLY want usefull pixels filling the whole screen. That's why I wish everything was just filmed in 16:9. I mean, that's plenty wide. When I want movies on DVD I just zoom in once so the whole screen is filled and with the exception of far right/left text in some movies I honestly don't miss out on anything. It doesn't cut off very much on the sides and really when you're filming who's gonna point the camera so where you're supposed to be looking is at the edge of view? No one. 16:9 is the only aspect ratio visual media should be in. That way everything is uniform and just fits.

    The article mentioned the confusing behavior of IE's back button... The confusion starts when you open IE from the start menu, because at that point IE throws away your browsing history, so that the back-button will return you to the start menu. It makes sense if you were opening IE to look at a new web page, but it's maddening if you were opening IE to resume a browsing session that had useful stuff in the web navigation history.

    The workaround is to switch to IE by holding down the back-button and selecting IE from the list of running apps. That opens IE without throwing away your browsing history, so that the back-button continues to work for web navigation.

    I actually removed the IE tile from the start menu, just to prevent myself from accidentally throwing out the browser history. I've always got two or three tabs open in IE, with meaningful history in each tab, so it was always aggravating to press the back button and get kicked back to the start menu.

    If you'd like to see this fixed in a future version of Windows Phone, please vote for it here:
