How do I recover pictures on a Sony Memory Card?

How to recover flash memory card pictures? ?

• My father-in-law has a Pentax digital camera from Korea and it uses 1 GB Sandisk flash card. I loaded the flash card on my Dell D420 Windows Vista notebook and it was asking me to format my e: drive and I canceled since I didn't want to lose all the picture data on the flash card. I put the flash card back in the digital camera then everything was erased and gone. Then I found a site called cardrecover.com and downloaded their evaluation version and was able to recover all the pictures but their trail version won;t let me save the pictures unless I pay $40 for thier stupid software. Does anyonw know where I can get a free version that I can save the recovered pics to my computer? Thanks and Happy New Year!!!

• Answer:

  I've used WinHex sucessfully, but they will want to be payed for the full version too. There must be freeware, but when I was looking for a solution using Google I didn't find anything I liked the look of, though that was a year or two back. Some Lexar cards come supplied with recovery software. It might be worth looking at their site or SanDisk's. They may want paying too. I didn't keep the Lexar software, but I think that was also a trial version.
