Instead of placing my sdhc card into the memory card slot on the imac I placed it by mistake in the dvd drive and it just swallowed it up and I have no idea how to get to it.
I have some very important information on there, anyone please help!!!
Wow that really sucks. I wouldn't try sticking anything in the drive slot in hopes of getting it out. The only way to get it out is to open it up and take the drive out. I also wouldn't recommend doing this yourself unless you have experience doing it.
Bring it to the apple store and see what they say. Thats your best option.
If you would have use MRoogle to search for this type of thing, you'd see that it happens often to some people. Just try searching with MRoogle next time.
