Hi my name is ***** ***** I will be the expert working with you today to help resolve your problem.
remove the sd card from the camera slot
you will see a slider switch on the sd card it must be on the locked position all you have to do is slide to to the other side.
let me know how it goes.
Done what you suggested then reinstated in vivitar vivicam and still got the same message
To identify the problem is with the sd card or the camera you will have to borrow an sd card from someone and try if the error persist with a different card then it the camera which has a problem with its sdcard slot sensor and that will require a repair.
and if the other card works fine that means your existing sd card is bad and its time to replace.
let me know if you have any question.
Tried another sd card and it says the same message
as i said its very easy to identify, its the camera slot which has a sd card sensor need a repair.
if the camera is under warranty you can take the camera to the service center and get it fixed for free.
let me know if you have any question for me.
