Windows 7: USB Flash Drive - Drive not online

USB Flash Drive - Drive not online

Hello and a very happy new year to all!

I have a 8 GB USB Flash Drive which shows up as "Disk 1" in Disk Management but never comes "Online". I tried changing the drive letter and double-clicking in Explorer. But it says "Please insert a disk into Remove Disk (I:)". When I try to format, it says "There is no disk in drive I:. Please insert a disk and try again."

I tried HP USB Disk Storage Format Tool but it says "There is no media in the specified device."

What could be the problem here?

Thanks for reading this. :)

It could be that the flash drive is defective. Test it in another computer.
It could be that the USB port is defective. Test the stick in another port, the ones in the back of the PC that are connected directly to the motherboard are best.

But that USB stick is recognized by the system because it is receiving power through the USB port, which is why Windows knows there is a device connected. But it can't tell what the device is, or find a file system on it.

Do those tests and let's see what what we find.

Are you sure you haven't purchased a fake pen drive?

Was the pendrive working properly before and for how long?

Make/ model/ manufacturer of the pendrive?

Did you buy it from a reputable vendor?

What prevents you from returning it to the vendor and getting a replacement? ( All genuine pen drives have suficiently long warranty periods.

( All fake drives will exhibit this error when one writes files larger than their true capacity, which may only be 256/512 MB though marked as 8/16/32/64/128 GB. They may also carry reputed brand names.)

The next thing is that it generally indicates that the micro-controller inside has become defective.

Notwithstanding, people have tried various things to bring such pendrives back to life. But first let us know the history.

Tried all that. Same problem. However, when I change ports, the drive letter changes from I to G.

I got this pendrive in a conference proceedings. Hence I don't know its make, its probably custom made. It was working pretty well. I've hardly used it for 3 months. Then it went into a washing machine with the clothes. I know I'm stupid: I should've checked my pockets. But it was 8 GB in all its glory. I want to try to fix it before throwing it away.

If it went in the washing machine....I doubt it will ever work or work correctly again. There is a slime chance if you know the make and model of it, there might be a firmware update that may kick start it....not likely but it's shot.

The key to dealing with water damaged electronics is to let the part(s) thoroughly dry BEFORE applying any electrical current.
The water alone will not harm anything, it won't dissolve much.
But turning the component ON while still wet can result in short circuit and burned out components.

There is an obvious exception for LCD displays. My daughter put her Sansa Fuze through the wash and the display never worked again, even though the rest of the unit was dried out.

Too late for this stick, I know, but a cautionary tale for others.

In your case it is evident that the electronics has gone bad. There is absolutely no point in trying out any rejuvenation procedures to bring it back to life. It will not work. And so that is it.

(There are programs that can read the nomenclature of the controller chip and then one can get the appropriate firmware to reflash it. In the case of fake pendrives that throw this particular error message, that is what "adventurous" people do and then the fake pendrives show their real capacity and become usable to that capacity. In the case of genuine pendrives that throw this error message, people have adopted some procedures to successfully format the drive making it usable as before. But given the history in your case those are not going to work either.)
