iMac Hard Disk Recovery

iMAC Z0CY:

I have an iMac Z0CY computer which I recently attached an Apple Mac DVD re-writer to. I connected it through the USB port, and I meant for it to burn off CDs in order to limit the amount of data which was retained on the Mac. I started out saving a little bit of data to the CD in order to test how it should look, and then I deleted the data that had been stored, and wrote a little bit more onto the CD. When I looked at the CD files to make sure that the second save had been successful, I found that the writer had inscribed these data files over the ones before, and that the earlier files were now completely missing. I have not been able to find the data files in the CD, even after extensive searching, and I also don’t know how to get the files back from the computer. They were deleted and then the trash was emptied, because I intended to free up more storage on the computer. However, I don’t want to lose this data, as it is quite important.

I have been having some Kernal Panic problems with my iMac. When I ran a Tech Tool search, it found some problems with my VRAM, so I thought that zapping the other parts of the RAM would solve the problem. However, when I did that, I found that the computer shut down very quickly, and on reboot it cannot access the hard drive. I have a lot of data that is on the drive, most of which I haven’t backed up in a while. I have tried to get some assistance from techy friends, but they have not been able to help me. I need some expert help in getting the hard drive started again, so that I can extract the data inside it. I don’t know if I will be able to do this on the drive as it currently is, but I am hoping to be able to rescue the OS so that I can get access to the data again. Can the files be rescued as they are very important to me?
