I accidentally deleted photos from my sd card and used a recovery software trail to see if they are on there. Which they are. I got back from my holiday and plugged in the camera to the PC (vista 32bit) and now it wants me to format before doing anything. Please help anyone. Thanks,

Matt

Hello,

to help us understand the problem better, can you tell me, when you used a photo recovery software, didn't it offer you the possibility to save the recovered pictures? It's not surprising that Windows wants to format the card if the software somehow tinkered with it, usually these softwares will save your pictures in a new location.

I was in New York on holiday so I download a trail software recovery program on US laptop in my apartment to check that the photos were still on there but the trial doesn't allow you to actually recover them so I thought I would wait til I get back to UK then sort it out. Plugged the SD card (2gb Scandisk) into my Dell monitor's card reader and it said it needs to be formatted. I have stored the card safely until I got home and now it suddenly doesnt work. I cannot use the recovery software because it will not show up as a drive until it has been formatted I assume. I will not format it though as the photos on here are priceless and would do nothing to risk damage. Im considering taking it to a specialist but I wanted to know if there was anything I could do first at home. I have the same problem when I plug the camera into the USB slot with the SD card in the camera. While I was out there I purchased another SD card as i'm aware that when you accidently delete something your not surposed to take anymore photos on the SD card. The second SD card I purchased In New York works fine and I have uploaded my photos to my PC.

Thanks for you quick response

If the new SD card works fine, then your other card is indeed corrupted. My guess is that something happened when you used the trial software (strange that the trial wouldn't recover any photos).

If you format your card, you still may be able to recover some or all images. But since these pictures are very special to you, don't experiment. Your best bet is to call a professional recovery service. As you may know, it can be expensive.

A few related comments:

You should always format a memory card in the camera, not on your computer. In fact, a brand new card should be formatted in the camera before using for the first time.

Also, if you need recovery software in the future buy a name brand one. 

So sorry to hear about your problem and I hope you get your photos back!! Let us know.

I thought that formatting the card on the computer would delete everything on the card. Isnt that what formatting does? Formatting on the camera what will that do could that improve my situation? Or no matter how many times you format there is always going to be a trace on the card of the photos that were previously on there.

Im going into my local camera store tommorow to find out what can be done but I dont ahve all tat much money so Im going to try and do things myself if possible. Appreciate the advice and help very much

Thank you

It is possible to recover photos after erasing and formatting a card. But there is no guarantee how many are recoverable, if any. I've recovered photos after formatting.

If professional recovery services are just too expensive, my thinking is what would I have to loose to format the card and then try a good image recovery program. You may end up with none, then again, you may end up recovering some.

Additional information about formatting:

There are two ways to format data. The fastest one is to simply erase the "addresses" of each file. The data is still there but no regular program  will be able to access it. This is when a recovery software wan help, since it will read every data block in there and rebuild the "addresses list". The other way to format, which takes longer, is to write over every data block, effectively erasing everything.

That's correct.

Until the data blocks are completely over written, you still may be able to recover them after a standard format.

If the original poster can;t get a professional to recover his images, he may have to format the memory card (in camera) for it to work again. Then he as a very small chance of recovering some of the images when using a decent recovery software.

Here are related articles:

Permanently delete images from card

http://www.digicamhelp.com/accessories/memory-cards/delete/

This article  points out that:

Image and video files can still be recovered until they are overwritten. To ensure no one is able to read or recover deleted images, format the card in your camera and then shoot random images until the card is filled again. Earlier images will be rewritten by random ones.
