Question about SanDisk MobileMate SD Plus 5-in-1 Media Card Reader (860571) Hard Drive

1 Answer

Sandisk Card Reader will not work

I recently had problems downloading images from my new Canon PowerShot S3IS camera and someone mentioned that it would be easier to get a card reader. So, I bought a Sandisk "5-in-1 card reader/writer" hoping to bypass my problems with the digital camera software. Instead, now I have run into a problem with the card reader... I have installed (and reinstalled) the software from the disk that the card reader came with. The button on the card reader is ONLY supposed to be lit up when a card is "correctly plugged in" - instead the light won't go off as long as it is connected to the computer. With a card or not. The when I plug the card in the light stays lit. If I push the button then nothing happens. If I open up the program on the computer it says "The SanDisk TransferMater Monitor is already running. Connect or insert your media card to launch the application" I have also plugged in all of my cards (I bought 3 new ones with the camera". Still no luck. I will probably post my problems with the digital camera software also. I just want to get my pics to my computer - didn't expect it to be so difficult.

    The light just stays a straight green. It does not change colors or blink (although the manual says that it should go to orange and/or blink at times). Even when there is no card it stays green. The computer doesn't have anything pop up or anything like that. When I doubleclick the program in the taskbar or in the start menu it just says to insert the card.

    also.. the manual says that you can go to the sandisk website and they have troubleshooting material on there. I went to the site and they list all kinds of model number card readers... there was probably about 10 of them.. and my model number was not even listed. This model number is sddr-99 if that helps.

What operating system are you using?

    XP should automatically recognize your card reader and install the drivers for it.

    I too have a Sandisk 5-in-one and it always has an amber light on while connected to the PC. A green LED should come on when you plug in a functional card. In fact when Windows detects the card it should open a box asking what you want to to do and if it should remember this action.

    Any of this describe what you're seeing?

    I just went to the Sandisk site and it is pretty useless when it comes to the card readers. I?ve never had a problem with card readers being defective, typically the issues are with memory card, how they are inserted or the USB port the reader is plugged into.

    -Insure you are inserting the memory card in the correct slot and oriented in the correct direction. I?m embarrassed to say I?ve made this mistake a couple of times.
    -Next ensure the card reader is plugged directly into a computer USB port, not a hub or extension cable. A hub, especially an un-powered one can cause all kinds of problems.
    -Next I would make sure the USB port you are using works correctly. The simplest way is to plug use another USB port (again a PC port) that is currently running another functional USB device.
    -I have had occasions where network drive mappings or other USB devices have interfered with the reader. Try unplugging your computer from your network, and unplug any external USB drives including USB thumb drives. Then attach your USB reader with card already inserted, start your computer and test.
    -If you still have not luck try to get hold of another memory card try it in your reader. You might even try another memory card type, after all the contacts in the reader could be damaged. Try formatting it with your camera and seeing if that works. I once had a card that had been corrupted and behaved oddly in the reader. A format fixed the problem for me.
    If after doing all this I would suggest you take it back to the retailer and ask for a replacement. If you do this within a week or so they generally will comply. If not call Sandisk, tell them what you?ve done and as for a warranty replacement.

Welcome to Fixya

Sounds like the pictures are hidden. Take out the memory card of the acmera and plug it in to a computer that has a card reader. Click the file and folder options of your computer then click the box that says SHOW HIDDEN FILES AND FOLDERS. You should be able to view your pictures now using the computer.

Card reader in camera or computor wont read sdhc cards

Although my SanDisk compactFlash cards 128 MB 256MB 4GB and 8GB cards are far from being full, when I open up my Canon Powershot A40, the follwing msg appears: CF card full. However, the original Canon Compactflash card FC 8M provided with my camera will still accept new photos. The problem is recent. Can someone help me.

I have a canon power shot s3is and when i put a sd card into it it says memory card error. i've tried a number of other sd cards it seems not to read any card. just randomly started.

It is likely that an internal metal contact (one or several ones) inside the sdcard reader are bent, or damaged.

You will need to have your camera reviewed by a qualified technician to have it repaired, since it requires open the camera and evaluate the sd card reader mechanism.

Best regards,

Bought new cannon a590 powershot and lost disc and operators manuel for camera and i cannot download photos to computer. Thanking you any help would be great

Buy a card reader for cheap and download photos using card reader. Remove SD card from camera and insert into card reader, then hookup card reader to computer through USB port. Try Picasa3 free software from Google to download images. Works great and all is inexpensive

Lost my Canon PowerShot A560 disk

As a solution I highly recommend that you forego the old cable to the camera route, and instead consider a card reader to download your photos to your computer. Card readers are very inexpensive, much much faster downloading photos from the camera, do not use the camera's batteries during download, and are much less prone to file corruption of the photos during the download.

You place the camera's card in the reader, and your computer sees it as a hard drive. You simply copy/paste or drag/drop your photos onto your hard drive. For all of these reasons, most professional photographers utilize card readers exclusively. Really, you'll save yourself a lot of headache. Here are some examples from Amazon. Also, don't be fooled by the cost. some of the cheap ones work just fine. Go by the reviews. Also make sure you get a reader that is stated capable of reading your card (particularly if you have an SDHC card):

For international readers, here's another source for card readers (free international shipping too :-)
