My computer has stopped recognizing my memory card - Help!!

[ellexmarie]

This just happened today. The card was purchased the day after Thanksgiving
so it's very new. It is a 4GB SD card from HP. I don't believe this is a
hardware problem as my digital camera Lexar 1GB Memory Stick Duo card and
adapter worked just fine today in the same slot. There has been no damage to
the card. It has a write-protection lock on the side and I've tried the card
with and without the lock on - neither way worked. I've also checked "My
Computer" and confirmed that the computer is not listing my card as a drive
any longer. I really need to get the video I took off of my camera and onto
the computer ASAP. Please let me know what I should do next!

I have a Gateway Laptop 3040 and I'm running Windows XP Home Edition SP3.

It's also not recognizing my camcorder via USB. I don't know what's going on!

A few things to try:

- Restart the computer.

- Try the memory card on a different machine, just to see if the data is
salvageable.
