How did you format the card? Reformat in the camera.

It would be possible to corrupt the card by removing it or the battery
while the card was being written to. But it should still be possible to
reformat the card and start again. If you can't do that, it does sound
like a bad card. The most likely time for a card to fail is the first
few hours of use (that is true for most electronic and mechanical
apparatus).

Not all of them, unfortunately, and then there are those people who
remove the card while it is being written to.... BAD KARMA

While a good idea, it is by no means required. Most cards are
pre-formatted and you can usually just drop them in and start shooting.

Having said that, it is possible certain cameras use a slightly
different file system and needs to format the card itself.

How does one get a burst of several shots if the camera is writing the
first shot to the card?

The on-board controller for the flash card will process tasks as needed.
There is no reason to worry about any functions related to the card
reading or writing data. The only caution is to not physically remove
the card or remove the batteries during a write operation.

It's likely just a defective card. Like most electronic devices, the
first 24-48 hours of actual use is the most common period where a device
that is going to fail, will do so.

Return the card and get it replaced.

Most cameras have a ram buffer that will hold a few pictures. The
larger that buffer is, the more pictures you can take before you must
wait for the pictures to be written to the card. The write speed does
become a limiting factor when the buffer fills up as the camera will not
take another picture until the buffer has emptied, at least one picture
to the card. This is the case whether the camera is an inexpensive P&S
or the most expensive DSLR you can buy.
