Micros sdhc wont connect to my cx330

[SPARTAN3444]

I have a sony cx330 and i got a new sandisk 8gb microsdhc for it and every time i put it in it says reinsert memory, verifying the positioning of the memory. i even tried it on other devices and it didn't read. i don't want to send it back just yet so any have any idea what's wrong, all open to any questions you might have about this

If it won't be read by any devices including your computer, it's broken and needs to be replaced.

Occasionally it's just a formatting issue, but if you tried formatting it can got errors, it's hopeless.
