But formatting the card will erase all data saved on your card. So, do you fix card is locked issue without losing data? Well, in such case if your media files are inaccessible then it is recommended that you must first try Memory Card Data Recovery software that is available for both Windows and Mac computer.
The recovery tool for a locked card will allow recovering photos, videos and audio files from the card. Below follow the step by step guide on how to recover inaccessible data from locked memory card by using Photo Recovery software. SD cards have a lock because it prevents anything to be written on it.
When an SD card is unlocked position, you can read and write the SD card. But, when it is in locked position, it will not allow you to make any changes to its file system, making it a read-only device. To do so, first insert the SD card to the source phone then restart your phone. Sometimes, the SD memory card removed unexpectedly or removing the memory card from a card reader while files are still being transferred to a computer. Due to these actions your Canon camera says that your memory card is locked.
So, in this case, formatting this SD card will resolve this issue. Bless you! Chosen Solution. Flying Dutchman flyingdutchman Rep: 7.
Remove the SD card from the camera. Check the position of the locking tab and make sure it is not in the LOCK position. Reinsert the card, and try again. If you are positively sure that the locking tab is not in the LOCK position, and the camera continues to tell you the card is locked, the camera's sensor switch might be stuck.
Sometimes, the locking tab pops out of its notch and goes missing. If you see the notch where the locking tab should be, but the locking tab itself is absent, you can tape over the notch with a tiny piece of thin adhesive tape. Be careful, if this is not done cleanly or the tape is too thick, the SD card might get stuck in the slot and you'll have difficulty getting it to eject. Inserting and releasing the card a few times, thereby jogging the sensor switch, may clear the problem.
As a last resort, you can give the SD card slot a blast of compressed air from a can. Be careful because the "air" from the can might cool down the card slot to the point of causing condensation, so wait a while before turning the camera on again. If the problem refuses to clear, have the camera looked at by someone knowledgeable. Was this answer helpful? The cards have a hidden partition containing how they work and if that it erased it could have caused the malfunction.
Have a look here. Very much like that little plastic tab used to work on VCR tapes, ie break it off to secure your old tape from getting taped over and later put a bit of scotch tape over the hole to allow recording to it again. I'd compare it to a known good card to see if the tab is shorter than it should be, could a bit have been broken off?
If all else fails just trim a bit of thin plastic and tape into place does the trick. To my knowledge, the implementation of write protect on a SD is the hosts' responsibility. There is no electronic switch which changes something in the SD card chip. Many external card readers don't have this detection thingy, and thus simply ignore the write protect switch. External cardreader Chronos USB3 multicard reader : write protect doens't work. It will happily write to the card no matter the setting.
So maybe something with your camera: the detection thingy thinks there is a gap on the side of the card. Thank you CubeAce. I don't know about the 45mbs vs 60mbs, but as an example, with this particular card, before I bought the USB3 card reader, I started to transfer a short 4k video file to my desktop MacPro computer with USB2 and it said it would take 29 minutes.
Copying videos with USB2 can literally take hours and even a few hundred pictures can take many minutes. There is a huge difference on my machines, so I felt impelled to buy a USB3 card. It could be coincidence that this happened, but as I just got the USB3 card reader and cable, I feel a correspondence, though, as I mentioned, I had copied once or twice using it.
I am confused about formatting. Are all of these cards formatted in the same way? Not camera by camera or maker by maker? I downloaded the sd card formatter at your link. It must be really old. The most recent OS they mention is Mountain Lion which is 5 years old. I am formatting now as I type.
It takes a very long time apparently. It is almost instant within the camera. The big question I have is whether formatting affects lock status. A professional photographer I know said he formats his card in his camera every time after he does an upload to his computer. It makes sense to me to have the camera format the card, but of course I cannot do that. What, exactly is a hard reset and how do I do it? Is that supposed to be done in the camera? I cannot format the card in the camera because it says it is write protected.
I am currently formatting it with a program on the computer, though there was no problem reading it on the computer. In other words, the computer read the format just fine.
If the program also formats it could cause problems or if the user formats a card in a Mac or PC it can also cause problems due to three possibilities. It destroys the hidden partition and removes the instruction section of the card telling it how to deal with malfunctions etc. Such cards can be left inoperable but manufacturers programs may be able to recreate the partition and restore functionality.
The camera when it formats creates it's own set of folders when you first load a new card into a camera if you format it when it goes in above that of the root folder. Often a camera formatted in one camera will have to be reformatted in the next camera before it will work properly as it doesn't recognise the other cameras folder designations.
Cameras often only do a quick format effectively only getting rid of the directory and telling the camera all blocks are free to rewrite over.
It does not do a complete wipe of each block. Transend cards are not towards the top end of the memory card market but once older style cards get hard to come by Transend are the only manufacturers where you can often find a card still in production.
Their memory is set up slightly differently and are normally more robust in use. The problem of the 4k video file is one of size. Older operating systems can not physically cope with such large transfer sizes or indeed use of them. This used to be a problem with large single audio files because the files were larger than the FAT table allowed.
If that is the case you may find some major playback issues anyway. I'm not sure how your operating system would read them while trying to transfer such files or whether the usb3 somehow allows it or makes it easier in some way but if your card is 40MBs then no matter what, that should be it's fastest transfer speed.
Step 3: Select the device that is write-protected and click Disable to remove the protection. If you don't remember the password you set when lock your SD card or the tips above fail to fix "memory card locked" error on your storage device, you can only force unlock your memory card by formatting, which will erase all the existing files on your device. Besides, data erased by force unlocking your SD card is difficult to recover. If you have successfully removed the error "memory card locked" but find there is data loss on your device, you can use the hard drive recovery software - EaseUS Data Recovery Wizard to recover the lost data.
Besides, although retrieving the data erased by force unlocking the device is hard to get back, you can also try the software to scan for lost files. The SD card will be listed under the Devices section. Choose the SD card and click "Scan" to start looking for your lost data. Step 2. The software will start a quick scan and then a deep scan automatically. The deep scan is powerful enough to find all lost files that even lost file names.
After the scanning process, you can check and filter wanted files in this program. Click "Filter" if you are looking for a specific file type, like photos, documents, videos or emails Step 3.
You can directly double-click the files to preview the content. After this, you can choose wanted files and click "Recover" to restore them to a secure location on your PC or other external storage devices.
