My laptop has a slot on the front for a SD card, the type that my D50 uses, its one of the reasons I bought this particular laptop... however I am upgrading to the D300 very soon (woohoo!!!) and it uses Compact Flash, Type I / II with UDMA support (I have no idea what udma is).. anywho, my power cord is directly beside my usb slots making it hard to fit my current card reader into the usb slot (my reader has a usb end sticking out of plastic instead of a usb end on a cord).. so my question is, do they make a sd2CF adapter thingy where I could still use my sd port for the CF cards, or should I just go ahead and buy another card reader? or what is UDMA and what about wireless? What would you do?

UDMA = Ultra DMA = Ultra Direct Memory Access. Describes the access mode to the storage device. UDMA is faster than DMA which is faster than non DMA. There are different specs and modes, but essentially UDMA is faster, faster is better.

I do not know of a SD to CF adapter. The form factor of the two cards is way different. The CF is larger/wider than the SD by at least a factor of two. USB card readers are cheap, and can read a whole lot more. You might want to look into a USB hub as well. That way you can just plug it in, and not worry about sizes. (I know what you mean about being close to the cord. Why they do that, I do not know. My SD cards are USB on the other end so that I don't need the reader for them, but sometimes cause problems on computers with limited space around the USB slot.)

Like previously said USB card readers are cheap so that may be your best option, however you could also look at a short USB extension cord. This will have a male connection on one end to plug into your laptop and a female connection on the other end for your USB card reader.

Thanks guys! I assumed there was no SD to CF adapter, but a girl can hope.. I will have no use for that sd slot now, and thats just annoying! lol

I will most likely get a new card reader... the boxy looking type with a cord.

Does anyone have an opinion on the new wireless technology or a link to any threads here discussing it (I looked but didn't see any)?

Buy a good, fast card and reader (that pair is $65 together from Amazon). Like the Sandisk Extreme series. For a 4gb card, you can spend 25 minutes waiting for it to download pictures (with a cheap card/reader), or 90 seconds. And in the long run, your time (and skipped frustration) is more valuable than a couple more bucks up front. =)

Unless I'm misreading things... there is such a thing.

no, alanfreed, I think she's looking for something to convert CF to SD..... which is physically impractical, because CF cards are MUCH bigger than SD cards.

Your best bet would be to just buy a fast CF card and a fast CF reader for USB, like everyone else said.

That's not how I'm interpreting her post... but I'll let her be the final word on that :) If she's wanting to continue using her SD port on her computer, she should be able to use the adapter I linked for use in the camera (putting the SD card into the adapter, put the adapter into the camera). Yank the SD card out of the CF adapter, and stick 'er in the computer like she's used to doing with the D50.

Yes, this would accomplish what the OP wants, though at about 3x the cost of a card reader.

On the other hand, leaving the adapter in the camera and taking the SD cards in and out of the adapter might eliminate the true bane of the CF format: bent pins in the camera bay from taking the cards in and out.

Brilliant!! I too thoughts you had lost your mind but now I see, put it in the camera! Awesome!

Hmm, I have to wonder about this as everyone has mentioned it at one point or another. I have had seven CF cards over a span of close to seven years, four card readers from $12 to $60, two cameras. I have never once bent a pin even rushing to slam a card in when something sudden was going on. In all of the sockets I have encountered there have been strong guides on either side to prevent the card from going in crooked.

I'm not trying to disagree per say but I am wondering if it is really a flaw with CF cards, or rather with the devices they are inserted into. You know the saying, if you don't know what you are pushing into, then you don't know what you will pull back out, always wear your rubbers, or something to that effect.

I purchased a similar adapter (I think it was made by ProMaster). I used it to for my xD cards. Although the xD cards worked fine by themselves in the camera and an xD reader, they would not work inside the CF/xD adapter when used in my Epson P3000 viewer. My workaround was to switch to CF cards. Maybe I got a bad adapter, I didn't try to find out but life has been sweet with CF. (Please don't press me for details. This is all I could scratch up from my organic memory.)

Same here. Sure, if you're careless and jam the sucker in there, I can see that happening. But I've also had CF cameras since 2001 with at least a dozen or more CF cards, and no problem. Ever.

Use a USB extension cord.

I've never bent a pin myself, but I have a camera (Canon A80)which I lent to someone who did manage to bend a pin; fortunately, ' . substr('//www.dpchallenge.com/images/user_icon/21.gif', strrpos('//www.dpchallenge.com/images/user_icon/21.gif', '/') + 1) . ' Brad was able to fix it.

But, if you're going to buy one adapter and several SD cards, and you don't need to use the adapter for the card reader or anything, why would you bother taking the adapter in and out of the camera anyway, unless it's really hard to get out the SD card otherwise.
