20 Most Recent SanDisk 4GB microSD High Capacity Memory Card - Page 5 Questions & Answers

Hi, a 4 GB card should be okay for the 2690, as long as it is one of the supported memory card types. The 2690 can accept memory cards up to 8 GB.

If the problem is partitioning you ned to run fdisk or similar to repartition. You will loose all data in the process. See e,g, http://support.microsoft.com/kb/255867 which describes the process for a HDD.

it should work fine. maybe the memory card is faulty.
have you tried the card in anything else to check that it works properly?

SOLUTION 1 - Unlock the memory card.

There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.

NOTE: If you are using a microSD/microSDHC card or a miniSD/miniSDHC card, insert the card into the standard SD adapter.


SOLUTION 2 - Toggle the lock switch.

If the lock switch is not on lock:
1. Slide the switch up and down. Repeat this 3 times.
2. Let it stay on the Lock position for 30 seconds.
3. Slide the switch up to unlock the card.
4. Try to transfer files into the device.

usually those card will have a lock (see here ) that will allow you to unlock the card and will let your write on it again. simply switch the the little switch to the other end (lock-off position) very gentle and attempt to write to the card

good luck!

if your camera does not contain a format feature in the firmware, you must use a PC with a card reader and use it to format the SD card. You can do this by going to my computer and right clicking on the removable media then the format option.

format the card using a reader and try again

Check how long has the product warranty with the service provider's product or visit this site http://www.sandisk.in/ Regularly that type but not repaired but contacting ScanDisk right through the web.
Good luck

Hello abh.... Remove the card and look very carefully around the edges.
You will see the mechanical lock mechanism which you merely slide from the lock to the unlock position. Joe

If you are trying to format this card through a PC don't bother, it will not work when you install it into the phone.
If you are trying to format this card in the phone, you may find that your phone will not access high capacity type cards as few older phones do, and by older, I mean if the phone is more then 6 months old, the chances are that it will not allow access to the card.
Some phones also have an upper limit to the size of the card they will address and most will not address any card larger then 2gig..
Of course, you may also have a faulty card, even from new, some of the high density cards are faulty..
If you can get access to a smaller card (like say a 1gig), try that in your phone. If it works then you will find that your phone cannot address high density cards.
I have a camera, less then 6 months old, will address normal 2gig cards but it will not allow high density 4 gig cards which is a pain but alas, nothing you can do about it..

ya.. surely!

Hold the SD card so the label is upright and facing you. Locate the switch on the left side and slide it up to unlock it. If you have a Micro SD card, put it into an SD card adapter. Slide up the switch on the adapter to unlock it.

Insert the SD card into your computer. If you do not have a built-in SD slot on your computer, then connect it with a USB adapter.

Open the Computer icon on the desktop. A window will open with a list of the available drives. Locate the drive the represents the SD card. The name of the drive may differ depending on you named it, or what the default name is.

Right-click on the drive and select Format. If it asks what you would like to format it to, select "FAT32" and click Start.

it might not be compactable with it. try to get a card reader to download it to ur pc

Go to or search for MiniTool.Theres an app to format any drive.

I would recommend a data recovery company like TechRx, Inc. for this type of issue. Commonly, corrupt cards require insertion into a NVRAM reader.

I wrote up an explanation, See here for details

look in "My computer" for removable medi or new drive letters to click on. They should behave just like a hard drive
