Hi Steve I use SanDisk Extreme Pro cards (16gb 90MB/s) and Active card reader for downloading my images. Every time the card is reasonably full it drops out in downloading resulting in not all of the images being copied to my computer hard disk. If I highlight more than a 100 raw images for download there is a 95% chance it will crash. This is frustrating as I need to shut down Adobe Bridge, eject the card reader and reload. It also means I need to reconcile between the card and computer to make sure everything is copied. What do you think is causing this? If you feel my problem could be with the card reader (which is a few years old) could you please recommend a good one? Thxs

Hello Peter -

What you describe could be any number of things so it's hard to say with any certainty. Are you doing anything else with the computer while the images are downloading? Perhaps some other task is interfering.

You could eliminate the card reader as a culprit by using your camera body to download the images. Just connect your camera body to your computer via a USB cable (probably a mini-USB on the camera side) and your operating system should recognize the cameras card reader as a mass storage device and install any necessary drivers automatically. Download the images in Bridge just as you're doing now. If they download fine, but still don't download when using the Active Card Reader, then you know the Active Card Reader is at issue. It might be defective, or it might need a driver upgrade. It wouldn't hurt to google Active Card Reader and find their site, and then download and install the latest drivers. There might even be a firmware upgrade for the card reader. This is rare, but it happens when they discover a defect which can be corrected via firmware.

If it continues to be a problem with the camera body, try exiting all other tasks and programs other than Adobe Bridge. See if that works. If it then works, start up each program one by one until you find the one interfering.

It could also be your CPU is overheating, or your memory is at issue. It takes CPU power to download images, and it could be it's just reaching its temperature threshold before 100 images are complete. What kind of computer is this, a laptop or desktop?

If you confirm your computer type, and that in fact your card reader is the issue, I'll recommend a few. If you have a Imac or Mac laptop.. confirm if you have a firewire port. And if it's FW400 or FW800. If you're going to get a new card reader you might as well get the one that takes best advantage of your computer.

Thanks Steve.

Its a strange one but I think your right in that perhaps my Imac is trying to backup to Airport while running the download. Last night I imported 500+ photo's via Lightroom and it worked without any problem, but the Imac would have backed up earlier in the day when I first switched it on. I will try again making sure backup is done first and not likely to interfere and see if the problems eliminated.

Hi Peter -

Narrowing it down would be good. It 'should' be able to work while other programs are working in the background, but often conflicts need to be solved.

Did you update to the latest drivers and operating system updates? This is a good starting point. Also, check the card reader manufacturer site for firmware updates. These are often simple to install and can make great differences.

Let's hope you've narrowed it down.

Steve, I wonder whether you have a recommendation for a source in Bangkok that sells eSATA card readers?
With the speed of the latest cards, the USB 2 is more and more the bottleneck these days, and I would love to upgrade my workstation with a (preferably built-in) eSATA PC card (or multi-card, though I guess the speed for SDHC cards is still slower) reader.

Sunny - I actually have an internal SATA CF card reader and learned through this experience that it is indeed fast (though not nearly as much as you'd think), but that the card needs to be mounted each and every time you put in a new card. The most solid way to do this is through rebooting the machine, or a less reliable way is to go into the drive manager and have it scan for new drives and then make it active. As you know, esata and sata work the same. So.. when they started coming out with esata card readers, and more sata card readers, I read a mixture of reports on how well they worked.. most required the reboot. So I never bothered with this route. I'd love to have an internal sata multi-reader, but I would have to read a very solid review where they've solved this issue.

And then there is USB3.0.. where the manufacturers of all card readers are on the cusp of releasing, or rather re-releasing, virtually all their readers in USB3.0. This will be great, and I figure we're months away from the announcements as I read the industry news.

If this is for a laptop, consider one of these: http://www.amazon.com/Expresscard-Adapter-Cf-Extreme-Pro/dp/B0035AZ9WG/ref=sr_1_1?ie=UTF8&qid=1297174955&sr=8-1 They work very well.
