Is my Micro SD card FUBAR?

[Deleted User]

The 32GB Micro SD card in my Dash Cam started misbehaving the other day, so, as a stop gap, I borrowed the 8GB card from my Mobile Phone.

Having installed a new 32GB card in my Dash Cam, I put the 8GB back in the Mobile Phone, but it was signalling error when I tried to view the contents.

I've tried formatting it in my PC, but it still isn't working in the phone.

Is the card FUBAR, or is it recoverable?

put it in the mobile phone again and format it from the phone.it should then work ok again

I usually find when my microsd cards fail that I can't format them either on the PC or in phone, I also can't add any more data although I may still be able to read the existing data on the card.

I'd agree with the post above to try formatting the card in phone.

Formatting a memory card may give you a very basic idea of whether it is functioning or not, but that really only tests a small proportion of the memory itself.

If you really want to confirm the integrity of a memory card you need to use a utility that writes data to every location and then goes back and checks that what it wrote is still there. Examples are H2testw and F3 - the former is Windows based, the latter Linux based.

F3 is in most of the common Linux repositories so it's easy to download, but it's command-line only.

Thanks for the advice guys, but I gave up (life's too short) and bought a new card.

Buying a new card is no guarantee that you'll end up with one that's fully functional. Both fakes and faulty (from new) cards are common these days.

I test all of mine from new, and send back any that have faults - I would not risk any unique content (e.g. photos) on an untested memory card.

It's working.

I bought it from a market stall, and installed and tested it, before paying for it.
