Good afternoon Linda!
You can view your manual here
RCA RCT6077W2 Manuals . If you go to page 10
RCA RCT6077W2 User Manual Micro usb Headphone Micro Sd it notes a couple of important caveats on the card:
- You can use MicroSD or MicroSDHC type cards
- Size limit of 32GB
- You are warned never to insert or remove the MicroSD card in 'On' mode (i.e. only insert/remove the card when the tablet is off)
Aside from that, it looks like things should work. To be sure on what is the root of the issue, you can:
- Insert your card into another device to verify that it works
- Format or Re-Format the card - the SD Card association has a formatting app here:
https://www.sdcard.org/downloads/formatter_4
- Make sure the card is legit. If it was purchased, for instance, off of Ebay, or other not-so-top-tier online store, as likely as not it's a fake made in China, likely with guts from manufacturing rejects. You might, for instance, get a card marked 32Gb that actually has a 2Gb chip in it with a hacked controller that says it's 32Gb. It'll seem to work OK for a few files, and at some point will just write your files into no-where. SD Insight, a free checker app for Android phones can be picked up here
