The reader may need re-iinstalling. or the port you are putting it in is incorrect,. try another stick to test the port or try the memory card in another PC to confirm the stick is OK

do you have a SD card reader for the computer? if not, getting one is a good idea. you can try putting the card into your computer to copy your pictures into your computer before formatting. And if you get the card reader from best buy. if this doesn't work you can always return it.

I'm having the same problem with a Transcend 4GB microSDHC card / microSD adapter. I have also found it probably has something to do with the card reader...either the card reader is an SD card reader trying to read an SDHC card OR the card reader is not able to read high-gigabyte SD cards (over 1 GB in some cases).

Please create a new folder on the memory card and rename the folder to MY MUSIC or MUSIC, now locate the music you want to put them on the memory card and copy them to the card

If the card is brand new, try to have the phone to format it, or use the PC to format it at FAT, not FAT32 or any other file system.

To my knowledge, razr's can not handle a 4gb card.  I believe 2GB is the highest.

Hello Everyone!!! I know how it feels when you are in a serious problem and no solution is helpful to you! I have a SAMSUNG SGH E250 and 1GB KINGSTON micRO SD card. I faced the same "Write protected" problem and I searched for this solution and didnt find a good one! NO SOLUTION HELPED ME!.. First of all I would like to tell all the Solution Submitters that micRO SD card doesnt have a switch on it but its adapter have it. I know those who have card readers can put their Cards in the adapters and slide the lock downwards (or to opposite direction) and after that they can put that adapter into Card reader and the problem will be solved !!! But this solution is for those who doesnt have card readers !!!


1. Put the card into the slot of your mobile and connect it via USB cable to your PC.

2. If you do have a driver CD of your mobile then install all the drivers.

3. When you are done and can see the card as "Removable disk" on your PC then Go to Tools in Top ( File, Edit, View, Favourites, Tools, Help) Then Folder Options - View - Show hidden files (tick on the Show hidden files) and also tick on the "Show system hidden files (This is important). Then Apply - OK...

4. Open the Removable Disk (Your Memory Card), You will find a hidden system file. Just delete that file with some special softwares (manual deleting will not let the file delete coz its write protected).

5. Try to copy some file in it, if it allows you to copy then CHEERS!!!

6. If not then reformat it with your mobile phone..

Actually I accidently did the same steps and deleted the esamsung something file and I SUCCEDED !!!

Same applies with All USB pendrives and Memory Cards...

You should check your manual most probably your phone cannot work with SDHC micro SD card. The only thing you can do is buy a 2GB micro sd card.

SanDisk 4GB... | Answered on Feb 11, 2009

it may be because of the usb port of the system or the usb of the pendrive.................

The Card Reader you are using is probably not compatible with SDHC Memory Cards (High Capacity SD). You may need to get an SCHC compatible reader or check the website for your product to see if the is a driver update. You can get a new reader for about $20 bones if needed. I had the same issue.

Make sure that the device you are using specifically is to Micro SD High Capacity format and not just Micro SD. If it says just micro SD on the manuals or on the unit, it can only use a 2gb card.

Please check the menu, to see after what time the cam should stop. Also check the battery. Bad battery will also cause a dashcam to go in sleep mode.

Just google "rescue my files"
Lots of sites are offering software to recover deleted files, or even files from a formatted drive.
Be aware, if you did write anything on the drive after formatting, it will decrease the chance of and the amount of files you can rescue.
Most sites offer a trail version wich you should use first, to see if there is still something to rescue. To my knowledge there were some good freeware programs, but not sure they are still there. I use a paid version, since I deleted a drive by accident
