I wanted to try out something which needed the continuous drive function on my A100. I set the camera up on a tripod, framed the picture, set the camera on continuous drive mode and fired away using the shutter release cable.
Imagine my surprise when only 3 pictures got taken. I understood that the camera would keep taking pictures until either the memory card got full (4GB) or the camera battery ran out of power.
I've checked through the manual and a couple of other books, but cannot see where I went wrong. The camera was in auto mode and I wasn't using flash.

What format were you taking them in? RAW, for example, will fill the buffer up quickly. Try it in a low grade jpeg and see if it improves.

Was shooting in RAW+jpg mode, which would have given me about 250 pics.

There is nothing in the manual to say that continuous drive works better in jpeg rather than RAW. I'll try again just using jpeg mode and see what happens.
Thanks for advice.

I know that it's not the same camera but my 7D has the following in the manual:
" The maximum number of frames that can be captured depends on the image size and quality settings".That's in the section dealing with continuous shooting.
All cameras have that sort of limitation - as you would expect because they operate at a finite speed and have a finite buffer. Obviously as technology progresses the limitation gets to be less and less relevant until, eventually, in practical terms it won't be a limitation.
Shooting RAW plus jpeg is the most demanding of the capture modes because it leads to the biggest file sizes and hence the lowest continuous rate. My manual has a little chart that indicates what can be expected. The highest rate is with standard jpeg and small file (as you would expect).

Thanks Mick. I've just looked through another book on the A100. The camera will only take 3 images continuously using RAW + jpeg and 6 using RAW alone. This is because of the transferrance rate of buffer to memory card.
If any Sony A100 users are reading this post, get hold of the book, Sony a DSLR-A100 Digital Field Guide, by David D Busch (IBSN 978-0-470-12656-1). Apologies if I've broken forum rules doing this plug.

That info is clearly stated in the manual! Actually, if you buy a fast card the A100 will exceed its sequence specs, and do up to 10 raw frames in a row and 6 raw + jpeg. But you need an Extreme IV or similar card. The A200 doesn't. It sticks to its specs regardless of the card, indicating a slower internal interface.

Assuming you have a reasonably fast card you will be able to shoot continuously in JPEG mode until the card fills up.
See Page 61 of the manual.
