Lost images on micro SD card.

[iLB]

I'm on the road at the moment and regularly switching micro SD cards between an android phone and my canon 1200 d to allow for better photo viewing and uploading. However it seems that for some reason some of the files on the cards are being over written or deleted once the switch is done.

Has anyone else experienced this? Is there a solution other than to stop doing it?

Thanks in advance,

Andy

I've had something like that before when I was switching a card between two devices, but I think it was creating new folders each time so it was hard to see the other information until I had access to a computer.

There's a chance your card is being formatted by one of the devices or at least having a directory structure written on to it when you load it. There might be a menu option to switch it off but there might not. I'd download a utility on my phone to examine the file structure and back the photos up before swapping.

It does seem to create extra android related files as soon as it is put into the phone. But I don't entirely understand why that would cause files to disappear.

I don't trust SD card, although being a cheapskate....... As far as the phone is concerned, you could use Dropbox which auto uploads your images to the web. They are safe and you can view them on any phone, PC.

Probably one of the directories is being overwritten, it creates several for photos, though without testing I don't know. There is usually an option on the camera to protect a photo or you could flick the lock switch on the SD card before you swop it which prevents it being written to. Do some tests with either of those options.

Would using a USB OTG cable to connect the camera to the Android phone as a mass storage device work?

All cameras use the DCIM folder as standard to store photos so when using different cameras (or phone and camera) as each bit of kit is running it's own count, there's a good chance photos will get overwritten. Eg. Take 10 photos on phone DSC_0001 - DSC_0010 and then put it in camera. The camera's counter starts at DSC_0001 and will overwrite.

I'm not sure there's a way round it so would suggest two cards.

My camera had the option not to start from zero each time, but did create extra folders when it was shifted between two different cameras (my daughter forgot to bring her card)

Two cards will solve the overwriting problem, but not the using the phone to view & upload images problem.

It will if you only upload from the camera card and don't take photos on the phone.

Just use a few SD's then leave the sorting out until you get home. They are cheap enough. Stock up before you get somewhere where you can't get them.

Or take the main photos on your camera, and then just take a few on your phone for keeping in touch photos.

Probably a bit off-topic, but if you have a memory card that really seems deceased, it's worth trying it in multiple different computers/devices. Be ready to grab anything you can if it twitches back to life for even a few minutes. I had a moribund card that eventually gave up its contents after dozens of attempts.

Even more off-topic, if your USB memory stick goes wonky, see if the manufacturer of the stick offers a recovery service. Hama used to, at about £60, all up. The alternative "experts" were well over £100 at the time. Fortunately, in its dying gasp, mine spilled the beans.

What format are you using for the images on the camera.

As I like to play, I often shoot RAW images as well as JPG

I download images via a WiFi Card to the iPad for, but it does not recognise the RAW images




These therefore appear to be "missing"
