An update:
Last weekend while doing some intensive file reorganization on my N900's SanDisk 64 GB microSDXC card via wifi & SSH, something happened, a couple of files got corrupted, & the whole card became read-only.

Looking around on the internet I saw that others with microSDXC cards had event similar to occur, some fixed by reformatting, some by using the SD card adapter in unlocked mode then reformatting, using different formatting tools like EaseUS, SDformatter, the windows format tool, etc. Many did not get the problem fixed, nor did I.

I contacted SanDisk, & they have been very good about the problem & are offering to replace the card. In the email exchange, SanDisk have mentioned:
Please allow us to inform you that your Nokia N900 does not officially support microSDXC type of cards. We have also tested the specific device and we recommend our microSDHC Ultra 4GB, 8GB, 16GB and 32GB.
The microSDXC Ultra 64GB may have worked in your phone, but we cannot guarantee that the new card will work without any issues.

Please allow us to inform you that for your convenience, SanDisk has launched an online Product Compatibility Tool; this application lists some of our cards recommended for your device and also suggests many compatible cards for a wide range of devices; this way you can make sure, that you purchase the right card for your device.

Having said the above we will strongly suggest you to replace your microSDXC Ultra 64GB with two microSDHC Ultra 32GB which are recommended and more suitable for your phone.
I am going for the replacement 64 GB microSDXC since it worked well for 6 months & because I suspect the damage occurred as a result of the huge scale wifi operation.

SanDisks compatibility chart for the N900 lists the 32 GB MicroSDHC as the largest recommended for the N900. I don't know what criteria was used, but I also notice that all their recommended cards for the N900 are MicroSDHC. I believe if I again wreck the replacement 64 GB microSDXC in the N900, I will buy a 64GB microSDHC & try that.

Presently, my old 32 GB microSDHC is back in the N900, & is nearly full!

Again, SanDisk have been very good in the process of warranty claim.
