Recovering Your Card's Data

When you go through this post you will know how to recover datas from a misfunctioning sd card.If your memory card is bad and proves difficult to repair then watch out for the next post.

To recover data's follow the steps below:

1
Stop using the card immediately if you
haven't already. If your camera displays a
message that says "Card Error", "Read
Error", or something similar, turn off the
camera and remove the memory card.
Continuing to try to use the card after this
point will reduce the likelihood of you
recovering all of the data on the card.

2
Search for a data recovery program. While
your card might be done for, there's still a
possibility that your data is recoverable.
Some of the most popular free data
recovery programs include the following:
Recuva - After you select your hard
drive location (in this case, your SD
card) and check the "Photos" option,
Recuva does all the hard work in the
background. Recommended for most
users.

CardRecovery - After a brief setup,
CardRecovery scans any attached SD
cards. Once your evaluation period with
CardRecovery is up, you'll need to pay
to continue using its services.
Photo Rec - This program has a
minimal interface and requires basic
knowledge of how to navigate the
Command Prompt program, so it isn't
recommended for beginners.

3
Download and install your selected data
recovery program. Typically, this process
will entail opening your recovery program's
page, clicking the Download button, and
double-clicking the downloaded setup file.
The location of the download button
will vary from site to site. If you can't
find it, try looking for it on the top or
the side of the site's page.

4
Connect your memory card to your
computer. Most PCs have a thin,
rectangular memory card slot with the word
"SD" next to it. This will most likely be on
the side of the computer's casing if it is a
laptop, or somewhere on the CPU box if it
is a desktop.
If your PC or Mac doesn't have an SD
card slot, you can buy an SD card
reader that plugs into your computer's
USB port for less than $10. [3]
You may have to allow your computer
permission to use your SD card before
you can access it.

5
Open your data recovery program. It should

be installed in whichever location you chose
earlier.

6
Follow the on-screen directions. You'll
usually need to select the memory card as
the location to scan and select the
"Photos" option in your data recovery
program's scan criteria before you can
successfully scan your attached SD card.
After the scan completes, most
programs will give you the option of
restoring or exporting all salvageable
photos to a location of your choice
(e.g., your desktop).
