Hey, everyone!

 

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.

 

Thanks!!!

Update: So now the drive is registering as an "unknown device." I've tried to update the drivers, but the drivers do not help resolve this issue. Does anyone have any hints/tips?

 

Thanks again!!!

Apparently you have tried it in two different systems, for starters right my computer then click on manage see if it shows.  I am leaving for the evening but I am sure more will jump in.

Hey Phil - I've just tried it; no dice. :/ Thanks for the suggestion, though.

Hello,

This might work if no drive letter is assigned to the flash drive.

Right click Computer, select Manage > Disk Managment. Do you see the USB flash drive in Disk Managment? If you do does it have a drive letter? If not, Right Click on the device and select Change Drive letter and give it some non-assigned letter.

Hey John! Solid advice, but I managed to fix it myself with some tinkering.

 

For anyone who might be having the same problem: there's a crystal, looking similar to an electrolytic capacitor, inside USB keys. I must have damaged mine when I dropped it earlier, because all I had to do to get the thing working again was remove a working crystal from a "throwaway" USB I had and use that to replace the damaged one. Presto, chango, the USB is back to normal!

 

Thanks to everyone who helped!!!

Thanks for that update. Very nice fix!

 

Edit: For everybody not familiar with the crystal.

I agree with JohnC - nice fix !  But just in case it lets go again, perhaps more permanently, do you have this data backed up any where else ?

 

Your data is the important stuff in any system, re-installing operating systems and applications is a real pain and replacing hardware may be expensive, but unless you have more than one copy of your data - if you lose it, it is lost.

 

@JohnC_21 #7  -  interesting article. I have never tried it but I must remember that one.
