microSD card and adapter write protection problem

Hello,

I've got a very strange problem with the microSD card + adapter from Toshiba. The adapter *does not have* the "lock" switch, that means you can't enable/disable write protection. At first I loaded some music from my PC to the card and then used the card in a Nokia cell phone and since then the card is write-protected. I can't delete anything on the card.
My question: how does the write protection work? Can I simply bridge some contacts (i.e. those that the MMC doesn't have) to disable the protection?

Regards
Sven

Are you sure it has no tab for the "lock" switch? Maybe it broke.

You can't delete stuff on it from your phone or from your PC? Try it on several devices. If it work on one device, but not another, then maybe the device is broken and not the card.

It looks like windows XP has some problem with some cards or some readers, there is a path in the windows regestry that makes the card read only.

I Had the same problem and read this... i run on 98 upstairs and found that if you install the driver and keep the switch off of lock it should let you highlight the media you want and then right click and hit send to (in my case) F: and it let me go from there.

Cameras, phones, MP3 players and all sorts of devices have this same exact problem. I have scoured the net looking for someone that has an answer and I have only found the same inane replies (flip the little switch (everyone tries that first}, remove read only attribute {you can't}, make sure you remove it from the phone properly {not while in use etc. - doesn't work either}, make sure the DRM allows you to use {irrelevant these are not DRM files and even if then only those files would be impacted}).
The problem seems to be either that the SW developers either deliberately leave the write protection (or read only) in place to prevent what they see as interference issues with other users writing "their" disk with data. (why don;t they just learn how to properly manage the issue?)
Or the SW developers think that writing to the device at the painfully slow rate via their app is ok...I am loading maps into a N95 phone - a map of NH is 12M and took 30 mins to load via the Nokia app. That means my 2G memory card would take 160 hours to write all of it....160 hours !!!

obviously I have little regard for sloppy programming (and its everywhere now literally everywhere)- I have even less regard for support services that don;t know of this issue (do they have google in the support center?) or don't care or don't know how to fix this problem (which I suspect is the real reason...hence th comment above)

If you know of a fix PLEASE let us know...I don't

Tape a small piece of brown package tape across the switch, keep doing this until it works. Mine took 3 pieces, but it works every time.

Other SD, MicroSD or other memory card problems exist, include needing to upgrade to a higher capacity card and copy all the files across to the new one. This may involve copyright issues, but surely owners who have bought devices (and presumably the licences to use any packaged applications) should be able to back them up or transfer them to new media?

Here's one Nokia phone owner's solution: MicroSD & Nokia SD Memory Card Copy, Transfer, Upgrade Problem

I have an LG enV... im assuming that its part of the LG software that formats the card because only the enV can write anything to it... is there anyway to get around this!?!?

As noted above, place some tape over the switch. I colored in the tape with a pen. It worked like a charm.

This is just like in the old days of 5.25" disks (anyone remember those?) and the high tech copy protect system they used.

I'm having this same problem with a 4gb micro sd card. I cant delete anything off the card, and my phone gets stuck while trying to open the songs. So I'm pretty much out of luck. I've tried it on several comps and nothing. I dont understand. Theres no switch on the micro sd card. Theres nothing I can do.

i have a similar problem with my new card. My nokia card is fine when connecting to my mac through a card reader or directy from my phome using the usb cord. But the sandisk card i just purchased does not want to load on to my desktop when i put it into the card reader and it is only recognized by my computer when i plug the phone into it with the usb cable... but then it is only on read only mode. I formated the card through the phone... but still i have no right to copy to it....i have written to the sandisk and nokia support with no answer at all.... is it the card that is broken?

I have a nokia 6085 and when i go into gallery it usually says PNY memory. But now it says memory card and has a lock sign next to it. when i click on it it asked for a password. Of course i dont know what the password is becase i just turned the phone on and it was locked. at least i assume locked. the micro sd card does not have a lock switch. I cant plug it into my computer becase the sd extender that came with it doesnt work.

is it possible that the service providers are finding a way to code & jam our cards? Mine worked fine till today. I took 3 pix, and read one txt. Tried to open the photos after I read the picture message, and the phone jammed up. Now the card is write protected, and I cannot add or delete content. My application is in a cell phone, if you could not tell.

I bought one 1GB microSD card of SanDisk for my Samsung cellphone. I am unable to add any file to it through Samsung PC Studio or Windows Explorer. Problem 'card is write protected'. It connects through USB as mass storage device to PC.
Any HELP please?
Thanks

No, the microSD cards do not have a write protect switch. BUT the SD adapter that they slide into do have a switch. I was skeptical but on my first try at taping the switch (because the switch just slides loosely back and forth), it worked! In my case, I taped the switch so it was positioned closest to the adapter contacts. Once transferring started, it took only about 2 minutes to copy 100 songs occupying about 440 megs of space. Hope this helps!

Access through Cellphone or through Adapter with write protect switch tapped (in both way via USB), I can not copy any file to the SanDisk microSD card as it is "write protected". I have formatted it in the Cellphone, as well as in Windows XP with SDFormatter program several times.
I am sure there is some thing done by the manufacturer.

Sometimes you only have to use another adapter or unplug and replug into the USB port.
Or use a different port. Go to the link in my previous post:

I have just had this problem occur and taping over the switch on the SD apater has solved the problem.

This will only work you those of you who are using a Micro SD in an SD adapter in an SD card reader, it took a couple of layers of sticky tape and a little piece of paper.

Reminds me of doctoring my old cassette tapes and video tapes so I could record over them... Ahh those were the days :)

I guess it's a case of tricking either the adapter or the card reader into thinking there is no switch, therefore no write protection.

But it DOES work!!!

Thanx all for this thread.

I HAVE FOUND A RESULT....USE ANY HOUSE HOLD DIGITAL CAMERA AND USE THE CAMERA TO SYNC THE microSD OR ANY OTHER SD CARD, THEN YOU CAN ADD OR DELETE ITEMS TO THE CARD AND USE IT ON A CELL PHONE OR ANY OTHER MULTI-MEDIA DEVICE.

WELL, someone on here said something about tape and paper and i tried that and viola!!! i put a piece of paper then three pieces of tape and OMG!!! it worked...im sooooo excited! FINALLY!!!! good luck everyone. i PROMISE itll work!!!!

I had the same problem with a San Disk Micro memory card, 1 gig. I used it with the adapter after buying it and copied a couple videos, jpgs', mp3's to the card... my Samsung A737 read it fine. A couple months later, I tried to delete some of the videos to add new ones and it said I couldn't, the card was write protected. I tired the switch in all positions, top - middle - and bottom, no luck. So, I connected the phone with a USB cable (proprietary style for Samsung) and loaded PC Studio (free from Samsung). It worked and I was able to delete files and add new ones, which now proves the memory card itself is not bad, but that stupid adapter. Rather than go thru the hastle I already did once a couple years ago sending back a card, I will do it with the usb cable and eventually pickup a bluetooth usb device and then I don't even have to connect the cable. I thought SanDisk would have the best cards but not too happy with them anymore! When a off brand 4 or 8 gig go on sale, I will try them next.

I HAVE A PROPER SOLUTION FOR THIS PROBLEM. IF U HAVE ANY PROBLEMS WITH YOUR SD CARD OR MICRO SD CARD WITH ADAPTOR. FIND A NOKIA MOBILE IN YOUR FRIENDS GROUP WHERE IN YOU CAN INSERT YOUR CARD AND FORMAT IT. IT WILL DEFENITELY WORK.IM SURE IT WILL WORK BECAUSE 5 OF MY CARDS ARE WHICH HAS SIMILAR PROBLEMS ARE WORKING NOW.

Hi, I`ve Had The Same Problem . I Bought A 2 GB Micro Scandisk & Threw It Away Cause I Could Niether Format Nor Add Things On It As It Was Saying Right Protected. Bought Another 1 & The Same Happened Again But I Sorted It .....It Wasn`t A Problem With Micro Disk It Was The Lock Switch On The Side Of The Other Cartridge The Microcard Slots Into That Was The Problem It Needs To Be Positioned About In The Middle & Hey Presto It Worked !!!AT LAST!!!
Hope This Helps...........

i tried the sticky tape, it doesnt work for the fact my micro sd card adapters lock key locks into place when you slide it to the locked/unlocked position. it does not slide freely. i tried putting opaque tape over the connector tooth closest to the cut edge of the sd adapter... the didnt work either. i tried formatting it in my camera and mp3 player. and that didnt work either. theres gotta be a program or setting you can access of some sort to truly fix the problem.

I had the same problem...sticky tape did not help..changing the card reader did though! luckily i had a spare that i had not used before, so when i swapped it..voila! success...i have retired the other reader to the old shoebox which keeps the electronics junk i no longer use....

I bought a SanDisk Micro SD Card w/Adapter and had the same "write protected" problem. I slid the write protecter switch to the middle and put a single peice of tape over the entire write protection area and that worked. Try that and see if this works.

Sun, 08 Feb 2009 01:44:03 +0000

I was pretty sceptical about the tape fix (thought that I must have missed some funky setting somewhere), but a piece of yellow post-it and 3 (1 then 2 layers did not sufficiently cover the indentation on side of card) layers of sellotape later and it works perfectly (it is a bit of a tight fit and requires a wee tug to remove it). Sometimes it is simple.

If anyone is still interested, the micros sd card does hold a set of configuration files in a hidden folder on the root of the drive. Although you maybe able to see them you will noit be able to just delete them. I have managed to format my micro SD card through various devices and resulted in a useable card; this is what I did.
1. Formatted the card in my Canon IXUS 9501S using a low level format option.
2. Inserted the card into my Nokia N82 and in the MEMORY app again formatted the card.
3. I then finally inserted the card into a micro SD USB flash adapter, not a micro SD to SD card adapter and again formatted the card using FAT32.

My micro SD card is a 8GB card, unbranded, supplied with my Nokia 5800. I could view the "Private" folder on the card after inserting it into the micro SD adapter, before I formating the final time.

I hope this is a bit more useful than the people who say "put some tape on it", which is clearly not the solution.

Just bought a Nokia 7510.It has a Nokia 512mb card in it. Nokia says I can go up to a 2 Gig disk. Anyway I bought a SanDisk adaptor & 2 Gig disk. My computer won't even show that the adaptor & disk are plugged in. When I plug my Nokia 512mb card in the SanDisk adaptor; every thoing works GREAT. I transferred about 100 photos to the Nokia card with no problem. The SanDisk card wont show up at all in the SanDisk adaptor. GoFigure. So I guess I'll buy a 2Gig Nokia card.

tape does the shizzle
USE THE TAPE

It took about 8 layers for it to work so combining paper and tape might be a shortcut
