Hello,

I'm having an issue with my USB thumb drive. I'm on my dad's computer; an old but serviceable thing running XP Home with SP3. The thumb drive is a Kingston DataTraveler 111, 16GB USB 3.0. It has worked perfectly on this computer and others for the past year (got it in January of 2013) and has not seen any abuse or accidents. It's been used quite a lot, but not excessively so (whatever that means) and certainly hasn't had to work any harder than could reasonably be expected of it, especially considering it's a quality brand.

The problem specifically: In the past two days or so, on two occasions, there's been the issue where you're "in" the drive file structure in Explorer and have been using the thumb drive for a bit, but suddenly the next double-click you do prompts you to insert a disk in DRIVE G: (the assigned letter on this computer). No huge thing: I just remove the thumb drive, reinsert it and am good to go again.

Just a short while ago, however, the problem took a turn for the worse. The same thing of Explorer (after me trying to open a file) suddenly saying there's no disk in drive G: and prompting me to insert one (you probably know the little window I'm talking about). Any text documents and what have you stay open however, and it's not until I try to save them that the problem shows itself.

This time, removing and reinserting the thumb drive didn't work as well, because what happened was that Windows after recognizing that something had been plugged into the USB port (which I suppose is "good" seeing as the last thumb drive that died on me didn't even elicit that much of a response from the system) didn't realize that it was the old familiar one, and instead started installing drivers for it, and they weren't even the drivers for DataTraveler111, but rather for "USB DISK 30X USB Device" which I've never heard of before. Anyway, once it was installed and done I tried to access it, but that had the same result as before the new driver install, which is that when I click "Removable drive (G: )" I get a prompt to insert a disk in drive G:. So basically the thumb drive shows up in Explorer as a drive but cannot be accessed because I'm prompted to insert a disk upon double-clicking it.

Tomorrow I'll have access to other computers and can then suss out whether the error is due to the thumb drive or the computer. But I was thinking that maybe there's an apparent solution even while stuck on this single system, and that's why I posted so soon.

Thank you very much in advance for all and any help!

UPDATE - I tried the thumb drive on an Asus X58c laptop with Windows 7 SP1. To summarize:

In Windows 7 Thumb drive recognized, but installed as USB DISK 30X USB Device instead of DataTraveler 111 (exactly the same as in Windows XP, weirdly). After being installed (when the little notification in the activity field disappears) however, the drive does NOT show up in Explorer. This is different from how it behaves in XP. However, its presence was at least recognized by Win 7, which I guess is something.

In Windows XP See first post for details. Thumb drive recognized, but installed as USB DISK 30X USB Device instead of DataTraveler 111. After being installed the drive shows up as a generic Removable drive (G: ) in Explorer, but prompts me to insert disk in Drive G: when I double-click it. If I right-click it and check Properties to check the size, it only shows 0 bytes available of 0 bytes in total.

In both 7 and XP, when I check the properties of another drive and from there look at the Hardware tab to see the listed drives, USB 30X shows up in the list.
