Hi

Does anyone have any recommendations as to the best software for restoring deleted images from memory cards.

Cheers

:facepalm: Should have guessed that from your username.

No friends with a PC - or don't you associate with them? :)

LOL... yes my Mrs has a PC laptop at home and very nice it is too. :)

And we even have one at work. I just need something will restore old deleted files.

Tried a couple of demo files but they didn't seem to restore much beyond the last set of images on the phone. So not much use there.

There seems to be loads of apps out there claiming to work miracles. Just a case of wading through the crap.

lexar image rescue 3, you can download it free from lexar, pc only though.

Yeah... they do a Mac version.


Boo... doesn't seem to recover very much :-(
i was expecting masses of files to come come up going back years. Only seems to have some files going back to the last couple of times it was used.

Assuming Macs handle file deletion in the same way as PCs, when you do a standard delete on a file it removed the reference to the file in the file structure, so the computer treats it as free space, but leaves the actual data intact (which is why it can be recovered), when you put new data on the card it will write on any "free" area which could well be where your old image was, so it will then be lost forever, so the more you have used the card since deleting the files the less likely you are ot be able to recover anything.

What is it you're trying to do exactly? There's a limit to what you can recover because each time you take a picture you're potentially overwriting multiple 'deleted' images and hence reducing the amount of deleted photos you can recover. If you format a card and appear to wipe all the pictures then immediately tried a file recovery you'd probably get most if not all the pictures back however if the camera was partially filled up then many of these deleted pictures would be permanently lost.

My choice for file recovery is File Scavenger although I can't see it being able to do any more in terms of recovering older deleted photos. Even if any are found it's likely to be just fragments of those files.

Thanks guys. You hear these stories where IT experts say that 'no data is ever deleted' from disk drives. Maybe this only applies to Hard drives.

or maybe you need sooper snooper technology to sniff out older files.

Hard drives are totally different as they use magnetic write heads to imprint the data pattern and when it's rewritten ther are residual fainter imprints of the original data still recoverable if you remove the top surface of the disk media coating.....

It is true insofar as the media ( HDD or memory card) are not written to after deletion
Fact is that the new files have to be written to the media and eventually all usable traces of the deleted files will be removed
Forensic technology can attempt to recover files even after a low level format but if you write rewrite often enough old data will no longer be recoverable as the clever algorithms needed to recover need a minimum amount of the old data to guess and reproduce what they were
If you delete files on a card and neither format it nor write any new files to it many of the programs will do a decent recovery job

Even they eventually hide their secrets if you format them with software designed to make data recovery impossible
(As used by MI5 or by the actors in "Spooks"..:laugh: )

I've got a bootable CD that will erase to that level Senu if you're really that worried about your Pr0n collection being found after you sell your PC :devil:

...takes quite some time BTW

It'll be in the post as soon as possible after I get the address that all the other "plan Brown Wrappers" get delivered to :rotfl:

...but seriously if any one needs such a facility before selling on a PC or sending a disk back just drop me a line
