This may or may not help but it's one hell of a coincidence so here goes...
I have found SD card readers to be extremely temperamental - you can find posts all over the web about shuffling the lock/unlock slider on the card to make the reader recognize the read/write status but in my recent experience the usb reader itself is usually the problem.
I bought a few card readers off eBay for around $1 each a couple of months ago (I need them for cash registers to transfer data to pc). They are really nasty plastic things like children's toys but they work just fine. I bought a card reader for around 10UKP a few weeks ago and it now refuses to allow writing to any card (properties of the card are described as 'unknown' when viewed in this reader and cards appear to be read-only).
This very morning I bough three 1UKP readers from a 'pound store' (uk residents... 'Poundland', get in there!) - they are also horribly made plastic with a usb connector on a bit of wire but they all work seamlessly!!
My advice is, splash out on a cheap reader and see if that fixes your problem.
