Ditto on 4GB micro sdhc card. Purchased Jan 2010. Died October 2010. May it rest in peace.
There is no switch on these cards.
Looks like there’s a reason for the deathly silence you’ve gotten on your post. From what I can gleen from the internet when these cards go bad they just quit allowing writes.
I’ve removed the card from my phone, put into sdhc card reader and plugged into both Mac OSX and Windows XP and tried formatting … no go. Data won’t go away. New data won’t write.
I’d LOVE to be corrected if I’m wrong, as I don’t have a receipt for this #$!* card and seriously doubt I could return it without one.
It’s been fine up until now. I’ve started at the card even under a magnifying glass and can’t find the switch. Where is it?
It’s this kind of card: http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc
I’ve tried reading it with my MobileMate (http://www.sandisk.com/products/mobile-memory-products/sandisk-mobilemate-micro-reader) and a Sandisk adaptor.
Can anyone tell me where this switch is?
