So, today's conundrum: I have a USB key (Lexar Firefly 16GB) which holds all of my teaching and grading materials for the past several years. It was working fine this morning, but as classes continued, I noticed that I was being erratically booted out of my PowerPoint presentations (which are stored on the key). When I got home, my USB key wasn't recognized or detected by any of the home computers, and the indicator light wouldn't show up.
I resoldered the light (it wasn't coming on; it does now), the joints, and the crystal in the hopes of coaxing it back to life, but while the indicator light now flashes on, I still can't get the computer to recognize the USB key or any of the files on it. I tried calling Lexar, but they weren't terribly helpful.
I have Windows Vista and Windows 7 on my home computers. I've tried TestDisk and Recuvera, but since the USB itself isn't found on the system, it was a moot point.
Are there any other methods that could work for recovering the data on the key? I could care less about the physical USB, but I'd really, REALLY love to be able to scootch the files on it over to my hard drive for safety.
