rconey Posted November 10, 2013 Share Posted November 10, 2013 <p>Hello all. After we transfer files to our computer from a card (compact flash in this case) we have to "eject" the card to safely remove it. This evidently turns off the power to the card reader. If I want to put another card into the same slot to transfer more pictures, how do I initialize the card reader again so that the computer recognizes the card has been inserted? Of course, restarting the computer reinitializes the card reader but I wonder if there is a faster way with a computer command. I am using Windows 7 Professional. Thanks.</p> Link to comment Share on other sites More sharing options...
peter_cohen Posted November 10, 2013 Share Posted November 10, 2013 <p>Are you using an external card reader or one that's incorporated into your computer in some way? I've used external card readers -- from several manufacturers -- and never had this happen.</p> Link to comment Share on other sites More sharing options...
Former P.N Member Posted November 10, 2013 Share Posted November 10, 2013 <p>If it's an external reader (USB/Firewire) unplugging the cable then plugging it back in should do the trick.</p> Link to comment Share on other sites More sharing options...
Charles_Webster Posted November 10, 2013 Share Posted November 10, 2013 <p>None of my card readers behave that way. And I "Eject" them every time.</p> <p><Chas></p> Link to comment Share on other sites More sharing options...
Dave410 Posted November 10, 2013 Share Posted November 10, 2013 <p>My computer gets confused about that sometimes too. I just unplug the USB cable and then plug it back in, and the computer recognizes the card reader again. No need to reboot the computer.</p> Link to comment Share on other sites More sharing options...
rconey Posted November 10, 2013 Author Share Posted November 10, 2013 <p>I am putting the card into the computer card reader. I have used a USB card reader before and found that THAT particular USB port is off and can't be used again, but since I have many that is not a problem. I assume the computer devise controller in some way switches off that particular slot or port.</p> Link to comment Share on other sites More sharing options...
fkohan Posted November 10, 2013 Share Posted November 10, 2013 Ejecting the card doesn't turn off power to the USB port. What it does is instruct Windows to flush the cache. In other words to write anything it may have pending in memory and close all connections to that card. if your computer doesn't recognize another card by simply inserting it, you have something going on.

allenahale Posted November 11, 2013 Share Posted November 11, 2013 <p>I have never had to "eject" a card reader to remove a CF card before inserting a new card. I just pull out the CF card and shove a different card into the reader. As Fernando states "you have something going on" In regards to your USB port - I use a "Plugable USB 2.0 10-Port Hub" I have 4 USB External Drives hooked up to it and when I need to - a USB Card Reader - never had a problem (I am running Windows 7 Ultimate). You should look into why that USB port can't be used - Software setting issue? Hardware issue?</p> Link to comment Share on other sites More sharing options...
frank_skomial Posted November 11, 2013 Share Posted November 11, 2013 <p>Try to eject only one card and not entire reader.<br> Readers with multiple slots assign separate volume letter for each, in Windows.<br> Then you know what letter is assigned to each reader slot, and eject only that card, while other cards/slots could remain unaffected.</p> Link to comment Share on other sites More sharing options...
rconey Posted November 12, 2013 Author Share Posted November 12, 2013 <p>This behavior has been true since I bought this computer 5 years ago. I believe it was the same on the prior computer. As far as separate card slots, yes if I use a CF card first I can then put in one SD card and have the computer pick it up. One read per slot seems to be the norm. Again, not a problem, just a curiosity.</p> Link to comment Share on other sites More sharing options...

rconey Posted February 12, 2014 Author Share Posted February 12, 2014 <p>I found that I had the Nikon software- Transfer NX set to disconnect automatically after transferring pictures. Removing that preference fixed the issue. I guess "hot" connect and disconnect is not a problem for CF or SD cards</p> Link to comment Share on other sites More sharing options...
