My camera card is suddenly write protected; can't turn that off
The memory card from my Canon camera, when inserted into the computer,
is now permanently write protected. This means that I can not delete picture files, as I have been doing for years. How can I undo this? "Properties" shows no "security" tab at all for setting permissions. -dan z- -- Someone who thinks logically provides a nice contrast to the real world. (Anonymous) |

How can I undo this? "Properties" shows no "security" tab at all for setting permissions. CompactFlash and SD cards are almost universally formatted to some version of FAT, so there isn't a security tab because the file system doesn't support any kind of security beyond "read-only" and "system". Assuming J. P. Gilliver's suggestion doesn't help, I would assume the card is failing and replace it. They have a finite lifespan, and generally fail to read-only mode. Eventually you'll find that both your computer and your camera are unable to use it at all. -- Eight years involved with the nuclear industry have taught me that when nothing can possibly go wrong and every avenue has been covered, then is the time to buy a house on the next continent. |

Read my post.
I'll bet if you put it in a Win 7 PC and do the error-check it will un-write-protect it. You may need an adapter SD to USB if your PC does not have an SD slot. I have to do this for a particular brand SanDisk flash drive once in a while. slate_leeper wrote: The memory card from my Canon camera, when inserted into the computer, is now permanently write protected.

The worse situation is if the card goes write-protected as you are putting it back in the camera. I've got into the habit of always checking that I can take a test photo as soon as I replace the card after copying data off it. Having the switch on the side, where it can slide to the locked position as the card is being inserted, is a slight design fault. I wonder how many people actually ever set the card to read-only and would miss it if the feature was removed... |

You may also need a USB-SD adaptor if the slot that is built into your desktop or laptop PC decides to stop recognising that the card has been inserted. My Win 7 desktop does this sometimes: it recognises the card until it is removed and then won't see it again if it re-inserted until the PC is rebooted. The drive is visible in Windows Explorer but the card is not detected. |

Having the switch on the side, where it can slide to the locked position as the card is being inserted, is a slight design fault. I wonder how many people actually ever set the card to read-only and would miss it if the feature was removed... It's a continuation of features on more ancient storage media. I have SCSI drives with a DIP switch bank on the drive, where one of the switches is WP. It prevents writes to a SCSI data drive. There have even been OSes that "tolerate" being read-only. Windows isn't one of them. Various floppy formats used to have density holes or write protect sliders. The 1.44MB floppy in front of me, has a slide switch for write protect. The inclusion of such a feature on an SD, is just "copying" the feature from history. It's of limited value in the real world, because of the ease of moving the switch to the other position, and overwriting the device. Of course, with an SD, it also has a security suite, and that could interfere with your fun too. I have no idea what features it's got, where you would enter a password and so on. But it got the name Secure Digital for some reason... If ATA hard drives had a WP switch, I'd be in Heaven, because it would mean I could install Windows on Drive X and "switch off" Drive Y and Drive Z and know for a fact that the MBR on Drive Y or Drive Z could not be overwritten by the OS install. It's little known, that if you switch off drives in the motherboard BIOS, it makes no difference at all - an OS can switch them on again. The beauty of WP switches, is they're electromechanical and it's harder for shenanigans to happen. That's a feature I miss, from having stopped buying SCSI drives. Paul |
