I've just bought a Kingston 4GB SD card to use in the work camera, so that I can shoot stuff that I can take home.
I've just stuck it in my card reader, and it's not showing up in the Finder, or Disk Utility.
What gives? The CF card I use in the little Samsung handy cam mounts as you'd expect, but not this card. In fact, the work's card didn't mount either. I've tried two card readers, same result - SD card not mounting.

Any hints?

Solved it - just tried unplugging it, and plugging it back in.
It's mounted now. Ta-da!

Are the cards the SDHC type as a lot of card readers (such as the one on my 18 month old Quad core) don't recognise them.

USB SDHC card readers are available for around a fiver.

Yeah, I got the SDHC compatible reader at the same time as the SDHC card.
Anyway, as I say, it's working now.

My card reader on my printer has stopped reading any of my SD cards! (non-SDHC). Piece of [LIFTED] HP!

On an SD card related theme I recently stuck my 2GB Extreme III card into my new camera and found that it now holds around 50 pictures (RAW+Jpeg). I used to get almost double that. I've got another 2x2GB Ultra II so I guess there'll be more card swapping now unless I fork out for a big fat expensive 8GB and replace the lot!

So don't bother with the JPEG. Just the RAW will be adequate.

I have 4GB CF cards for my camera, and I can get about 400 RAW images on each.

Taking a RAW and Jpeg at the same time is quite useful though. It gives me a pretty good preview before jumping into my RAW software. To be honest its not the Jpegs that eat the space, its the massive RAW files from the 14.6mp sensor.

Okay, I just formatted my current 4GB card, and changed the setting to RAW+large JPEG. It halves the quantity I can store on my card on my 10MP camera (usually about 400 RAW files alone). So, I'd guess by dropping out the JPEG you'd instantly get about 100 per 2GB. If you want to store more images on your card, then trim the excess baggage.

I kind of understand why you're working the way you do, but I personally haven't found any benefit to having the JPEG be honest. I can review the RAW on the back of the camera with the histograms to check the exposure, I can download to the computer and review the RAW files there (the Mac OS can read the RAW files from most cameras which means QuickLook, Preview and iPhoto can open them), and again once I've imported to Aperture where I do all the work. Having a JPEG hanging about for the ride is no benefit to me.

I know some pros have RAW+JPEG, because it means they can fire a JPEG off to a client almost immediately, but if you're going to work on a file in post production, the JPEG is just filling space to no real end, in my opinion.

Eh?
Do you not view the images on the screen of the camera? Does that not tell you if it's a good enough shot to keep?
You look at the jpeg and decide weather you want to keep the RAW?
If it's space on your cards that's the problem ditch the camera generated jpeg and then, if you really must, generate a jpeg of each image when on your computer.

Of course I look at images on the screen. Dont take me for being stupid. When I stick the camera into the PC though and download the images having a JPEG version means I can quickly browse through entire folder, having a full size preview, and then decide which images I might want to spend time developing the RAW data. If I've been out and taken 200 pictures I'm not going to, nor want to, develop each and every picture. Some will simply stay as their original jpeg.

Can't you just browse the RAW images?

Not as quickly as the Jpeg in an XP window - filmstrip view. Requires no opening of any other software, they're just there to see as soon as they hit the PC hard drive.

Ah, sorry. I just assumed the OS would let you preview the RAW files without opening them. Is there an option on the camera for reducing the size of the JPEGs it takes? From memory my Canon has a number of different jpeg sizes. It probably won't save you much space, but it might be worth a shot.
