Title: USB-Stick problem
Post by: Sorunome on April 27, 2012, 01:38:17 pm
Hey, I got a problem with my 16GB Verbatim USB-Stick.
it used to work perfectly but suddenly no pc can detect that USB-Stick, no matter which OS, except the ones that are connected to out school network.
It also happened right after connecting it to one of the school PCs.
Is it some kind of virus?
If so, how do I get red of it?
Please help me!

Can you insert the usb stick into a Linux computer, and run "dmesg|tail -n 20" in a terminal and post the output?
This way we can see if there is an error with mounting or with the usb drive itself.

hmm....try running lsusb and post that. It looks like dmesg is pretty full. I'm assuming sda5 is your hard drive.

Or maybe....did you reformat your flash drive? If so, did you change it to ext2, 3 or 4 rather than FAT32? Windows can't read ext filesystems without special software.

Hmm. Could you plug out/plug in your usb drive and give me the dmesg messages again? That way I have the usb drive messages.

Thanks.

I'm fairly sure the "Trust international" one is relating to a bluetooth adapter, since I saw that when googling it, and bluetooth was pasted all over your dmesg. :P Do you have any other USB devices in? Try removing the drive and doing lsusb again. If an entry disappears, then the devices is registering with the system, at the very least.

Strange, I do not see any trace of your USB drive. Or the usb connection of the usb drive has some corrosion .. or it's broken :/
(Or it was not in your computer when you ran dmesg :D )

But....it is still recognized of the pcs connected to the school network

Oh, that is very strange.
Do you have to problem in more than one computer?
Title: Re: USB-Stick problem
Post by: Sorunome on April 27, 2012, 03:22:36 pm
I don't get that statement, but I already tried at many computers outside of the school networks, also with different OSes, Win7, WinXP, Linux Mint , Fedora, Ubuntu

Sorry, I misread your first post.
It is very strange that you only can view the content of your USB drive in school.
And I do not see any trace of it in dmesg.

Can it be you physically damaged the usb plug a bit, making that only the PC's in your school can read it (because of different usb sockets the computer have)?

There are also different pc models in school and it works on all of them, so no.
I just carry it all the time along on my chain ring but as I said, in school it is still working.

WOW, what is going on?
I had the stick all the time in and suddenly it is recognized! *yay*
let's see what happens if I deplug and replug it...
EDIT: It works now normal on my pc, maybe linux fixed it :D
Title: Re: USB-Stick problem
Post by: Jim Bauwens on April 27, 2012, 04:12:06 pm
Yay :D

Although I doubt Linux fixed it :P
Maybe the USB drive has some lose component inside, and sometimes it works, sometimes not.
It might be that because the drive got a bit warmer which made that the component moved a bit.

Post by: Sorunome on April 27, 2012, 04:17:54 pm
Is there some chance of checking it?
Title: Re: USB-Stick problem
Post by: Jim Bauwens on April 27, 2012, 04:26:01 pm
If you can somehow open it, you can. But that depends from usb drive to usb drive.
And many times it's quite hard to put it back together.

It's very possible that the connector was loose, just play with the drive up and down to see if it disconnects/reconnects.

I think it's a loose USB port that is about to die or something, but I could be wrong. If this happens again, try plugging another USB device in that port such as a calculator or a phone to see if it gets detected fine.

That didn't work

I tried that one also, the port is working well, I also tried on many other PCs, but now it is working somehow... :)
