I use my friend's USB flash drive (Corsair flash voyager 16gb) to transfer files from my laptop to my desktop computer.

However, since a couple of days my laptop stopped recognizing the USB key.. while there is still no problems with all other computers.

I use Windows 7 64 bits if that can help.

I tried uninstalling the driver, rebooting and all those kind of tricks, but it won't work.

When I connect it and open the "My computer" window, I see "Removable Disk (G:)" for a moment, then it disappears... then it reappears again and it keeps doing that periodically. I can't even right click then hit "Properties" because it disappears.

As I recall, it DOES work on every other computers, I think it has to do with the driver but what can I do?

You might have power issues with your computer, but please check first if you have Laptop's BiOS Update from the manufacturer website, most of the times it fixes those issues. – Miro co Oct 15 '11 at 21:08
If your laptop has more than one USB port, try in a different one. Seems like a loose connector to me. – haimg Oct 15 '11 at 21:24
I tried on every USB port possible, it wouldn't change a thing. Also, other USB devices (like mice) are working normally. I will try to do every windows update possible, as well with my "Vaio care center" to see if there are more sony updates available. No offense but I don't think it'll work (but I sure do hope it would!) – dominicbri7 Oct 15 '11 at 22:03

I had the same and solved this by:

  • downloading the 64 bit USBDeview
  • run as administrator and removed all occurrences of my USB (you'll need to know its Device Description)
  • plug in the USB; possibly in an other port to force Windows to reinitialise it

This worked for me!

Try plugging your laptop in if you haven't already while using it. I regularly see issues with external HDD's failing to be recognized when the laptop is on battery power. Maybe the same issue is happening with your USB stick.

Hmm I didn't think of that, I'll try next time I get my hands on that same USB drive – dominicbri7 Nov 23 '11 at 23:20
