I have been having so much fun with streaming media (qtify, spotify, @scene, france24, flash-based stuff) that I hadn't tried moving my music onto my N900. The fastest way to do should be to move the 16Gb Micro-SDHC that's been in my N810 via an adapte, but the N900 doesn't recognize the flash chip when I insert it. Or any others, I've tried 5 now. These VFAT formatted flash chips work in other devices like my N810 and E71.
A quick "dpkg -l | grep mount" turned up a package called ke-recv which evidently supports mounting removable media. Forcing a reinstall of this package hasn't helped.
Other than a completely non-functional micro-SDHC slot, what are the possible explanations? I am not putting them in upside down, or anything simple like that...

Connect N900 to pc, insert micro sd into PC and then transfer?

Have you put the back cover back on? The card doesn't get mounted if the cover's off.
What's the sensor/interlock that checks if the back is on? A bad sensor could explain this problem, and maybe I could override it.
Are you certain that the back cover is required for the memory card to be mounted? The manual (http://nds1.nokia.com/phones/files/g...N900_UG_en.pdf) says to put the cover back on, like a reasonable person would do. It *doesn't* say anything explicit about the back cover being required for the mount.

I don't know what's up so all I can suggest is the usual: Have you ran a dmesg and noticed any error messages when inserting the card?

I do get cam_shutter state messages in dmesg, and the corresponding platform_cam_shutter property messages. I am getting these message for
- popping the cover on and off
- manipulating the levns cover
- changing the view of the sensor below the camera lens from light to dark, either by covering it with my finger or just waving the N900 around.

This seems very similar to the problem that I recently encountered.
I first noticed that my camera was failing to fire when I opened the lens cover/slider. I checked dmesg, and i could see that it wasn't a software problem related to a dodgy package - the camera shutter changes were being correctly logged (cam_shutter), and the problem persisted after reflashing.
I then also noticed that none of my external cards (that were previously working) could be mounted by my device. I wondered if they could be related...
So, I popped into Vodaphone, and tested another back cover, and lo and behold, the camera and card started working again...the fault was positively confirmed to be with the back cover.
I suspect there is a sensor of some sort embedded in kickstand of the back cover that has become displaced or faulty.
I would suggest that you check if the camera software fires when you open the lens cover, and test with another N900 back cover if possible.
