Is the Original Data on the Card Secure?

[Vulmer]

Hello!

As for many other people, my Canon Powershot A520 informed that the SD card is corrupted and then "no image" - how unfortunate!

My question is: Does ZAR modify the original data on a SD card (or any other) when recovering, or does it operate on an image copy of my SD card?

So can I try as many times as I want without fear that frequent reading would damage the data further?

I have understood this is important because flash cards work differently than HDs: when data is read from a flash, it is erased and have to be written again in the same place by the system reading.

How long could it take to recover my 400 jpg pictures from a 1gb SD card?

Sorry - missed your message somehow.

ZAR reads the actual card. However, no writes are performed to the card.
ZAR copies files it finds on the card to whatever destination you specify.
As long as you copy files to your hard drive (NEVER copy anything back to the damaged card), the whole process is read-only.

Typical flash card would sustain quite a number of read/write cycles. Something on the order of several months non-stop writes. So the card wear is not a practical concern.

Thanks for your fast reply!

I choosed ZAR partially because of fast support responses in the forum.

Good work overall! I'm going to recommend ZAR for my friends. It was through a recommendation in a web forum I found ZAR.

I just recommend that you include more technical details in the homepage to be more convincing. The people that use tools like this are often tech savvy anyway.
