Tools to retrieve images from dead hard drive and/or deleted partitions



Ok, first, sorry to ask two questions at a time: dead drives and deleted partitions are different things, I know that.

Let me explain "my" (they are, in fact, friend's problems) two problems (from different peoples).

===
0) the common part.
By the past, I've did some researches about forensics (just as an amateur) and learned that you mostly work on copies of media from which you are trying to recover data. But the 2 HD from which I need to recover images (mostly jpeg, I guess. The users only said that's photos, ignoring, and does not willing to know, everything about format - but if that was not computer stuff, they would have know what they've used... - ) are bigger than all my current disks ! One is 500Gb, the other is 1Tb, where mine are mostly a bunch of 40/80Gb + 1 or 2 of 250Gb.

1)
I have a hard disk (1Tb, the bigger) which gave me many errors when I am trying to read it. It makes it very slow to even read, but I've been able to determine that it contains jpg images with a classic file browser. I did not managed to copy any data on a safer place... I am feared I will not even be able to retrieve one photo with my conventional hardware... but maybe some of you will have an idea?

2)
I have an external hard disk which is readable without troubles. But partitions were probably destroyed, AFAIK. The user knows (as usual) nothing about what happened, so I do not even know if the partition system have been remade, or if it is simply a problem like "format c:".
There are 2 partitions:
_ 1: the smaller, some Gb only IIRC, which was of type FAT when I looked (or was it FAT32? Is it is very different?) _ 2: the bigger, and not a little, from my memory, it takes at least 80% of the whole disk, which is NTFS, I guess most data is there.

===

So, do someone have faced one of those problems, and come to a solution?

Of course, I've said to their owners that keeping data on only one HD is suicidal, I've said that they can probably pay big amounts of money to specialized establishments to have them back, and have kept their hardware for some months (without using them), as a sanction (well, I tried at some times to take an eye, but had other things to do).

But, now, I'm in holidays, Christmas passed, and I'm thinking that could be an interesting gift to give back to people their photos of children and drunken nights, and I hope someone here could help me to do that for them :)

I've big fears that the owner of (1) will have no other choice that asking to people with dedicated hardware, but I ask in case... for (2), I've more hopes, IF the user stopped the destructive process before the disk was fully erased, but I'll need the good tools.
