SD memory cards
Remove the card, slide the lock switch back and forth
several times to clear any dust off the contacts. Unlock
the card, then try it again.
Can the camera read the card? Is there anything on it?
Can the camera re-format/erase it?
Can you plug the memory card into a laptop, either directly,
or by using an adapter for the PCMCIA slot, and test it?
On my laptop, the card mounts as if it were a hard-drive,
with a drive letter. I can then browse through it, using
Windows explorer.
Once (if) the card is detected by the PC, open up MyComputer,
and click on:
VIEW --> DETAILS.
This should show you additional columns with hard-drive
information.
1) Check to see how big the memory card is (or detects)
How much room is left ?!
2) How is it formatted: FAT-16, FAT-32, NTFS
3) If the card is NTFS (not likely) make sure you
set the root security settings:
Righ click on the SD memory drive letter:
---> Properties ----> Security ----> Add ---> Everyone
Then set the EVERYONE's access level to FULL CONTROL
If you get an error message, stating that you are not
authorized to view or change the security settings for
this device, go into advanced security settings, and
take ownership of the device. Then exit and try again.
(You need to have an administrator priv's account to do this)
4) Try to browse the memory card, do you see any files ?
5) Try to copy them to your computer ?
6) Was the memory card full ? --> clear it, delete files
7) Can you reformat the memory card ?
Right click ---> format ---> accept any default settings
8) On you icon tray bar, look for a green arrow icon:
Click safely remove drive....
Wait for Windows to properly finalize and the drive
(memory module) and then remove it from the PC
9) If you do not own a laptop, take the card back to the store,
where you bought it, and ask them to try to recover any
pictures or files that may be on it, and then clear and
reformat it.
10) At this point, if the card will not function, it is time to
purchase another one.
11) Flash memory cards will fail after a limited number of
read/write cycles, due to internal degradation
with use. Unlike most other electronics, these chips have
a finite life (erase/write) cycles.
12) Don't overlook an "lock" or protection settings implemented
by the camera, to protect you from you :)
The camera could be simply telling you that there are
forgotten pictures on this stick and you cannot
over-write them unless you unlock the card first.
