So I tried WP7 formatted SD cards on the N900 to so whether it is supported or not. I thought this might be since WP7 SD's can be accessed by the N8 ... alas that wasn't the case. But seeing that Nokia is going WP7 bound, wouldn't it be sweet if we can reformat our SD's with the N900 whenever the need requires. In any case does anyone know if it is even possible for the N900 to detect the SD once inserted?

dd if=/dev/zero of=/dev/mmcblk1
After a few seconds, format it with the file manager.

Note that WP7 formats the SD in some funky Linear+Stripe RAID mode.

Really? So when you take the card out of the WP7 device, the internal storage is FUBAR?

Yes. At least, it used to be that way; may have changed recently. I don't keep up to date on WP7, really...

Unfortunately that does not work, because the SD isn't even recognized by the file manager ... meaning a drive doesn't even show up. Any other clever insights that anyone with a brain would of tried?

I've tried: dd if=/dev/zero of=/dev/mmcblk1

No luck I'm afraid, and this might become the norm with SD cards used on Nokia devices because they become FUBAR after WP7 integrates it with it's formatting method.

This is what I get:

/home/user # ls -l /dev/mmc*
brw-rw---- 1 root floppy 179, 0 Dec 31 1969 /dev/mmcblk0
brw-rw---- 1 root floppy 179, 1 Dec 31 1969 /dev/mmcblk0p1
brw-rw---- 1 root floppy 179, 2 Dec 31 1969 /dev/mmcblk0p2
brw-rw---- 1 root floppy 179, 3 Dec 31 1969 /dev/mmcblk0p3

Oddly it has a strange date and year. Does it mean the N900 can atleast see the microSD but can't access it?

The following is a couple of links for reference purposes:

1) http://support.microsoft.com/kb/2450831/en-us
2) http://forum.xda-developers.com/showthread.php?t=840524

The WP7 device is formatted with CPRM:

Making the access to it require both a hardware layer and a software layer that supports it.

In the XDA forum someone said the Linux kernel has the software support required for detecting the microSD:

I would be puzzled if you would be able to use a flash card if this card was previously used in a WP7 phone. There's even a KB article which "explains" this: http://support.microsoft.com/kb/2450831

Maybe this article helps, didn't check as i'm travelling: http://www.amarjit.info/2011/01/how-...n-wp7-and.html
