USB Flash drive unable to detect on Mandriva 2010.2
 

USB Flash Drive unable to mount on Mandriva 2010.2. Some USB Device are detected example of these are printers, usb bluetooth, etc. Only Mass Storage are not detected. Thanks in advance.

as root tail /var/log/messages as you plug in the usb device. you should see it as /dev/sdX_something_or_other, or once you have it plugged into the computer run fdisk -l. both work for identifying the device. the tail will give you more details about what the system sees and if it is able to access the device or not. you will get errors if it is unable to access the device.

once you get that info report back with fdisk -l, or the /dev/sdX# from /var/log/messages and ill help you mount and access the device.

result of tail /var/log/messages
result of fdisk -l
thanks in advance

At first glance, I would suspect that your USB device isn't formatted. Also, for "fdisk -l" to be useful, you need to specify the device for the correct drive--the USB drive. /dev/sda is almost always reserved for your operating system's system disk.

Please do this and post the output:
ls /dev/sd*

and:
lsusb

and (as root):
blkid

and (as root):
for i in `ls /dev/sd*` ; do fdisk -l "$i" ; done

Please note that the "`" marks in the above are "backticks," which are found to the left of the "1" key on your keyboard (QWERTY). When in doubt, copy and paste.

Thanks for using "quote" tags, above; please use "code" tags for these, as they'll be pretty long and might contain characters that would get turned into smileys. :D

If your drive isn't formatted, it won't show up in most places until you format it. We can help you with that. :) If it IS formatted and isn't showing up, the above commands should reveal as much, and we can go from there.

Please see results

interesting. the lsubs shows the flash drive, but none of the others show that the system did anything with it.

try this. while running tail -f /var/log/messages (this will catch the end of the file thus any changes you will see on the screen) and remove the flash drive. wait no less then 30sec. then plug the flash drive back in.

Odds are that it will be detected as /dev/sdb as sda is your internal HDD.

If the system still does not see the flash drive as a /dev/sdX, then we have problems that might be out of my skill set to help.

do we know for 100% that this flash drive works? if so what OS have you tested it in? is it formatted FAT32 or NTFS or other?

Based on what you posted, it looks like the flash drive isn't working. The reason is you're only seeing /dev/sdaxx, which is your hard drive. You should also see /dev/sdbxx, which would (at the very least), be the un-formatted stick. You don't.

Does this same device work in another machine? Has it EVER worked? As root, with the drive unplugged, run "dmesg -c", then plug the drive in and run "dmesg", and post the results.

I've seen this kind of thing before with problematic flash drives, so I concur with the others here that it looks to be non-functional due to a hardware problem in the drive. If you're certain that it (still) works with other machines and/or other operating systems, we can go from there, but it looks "dead" to me.

@ TBone and DaneM

Yes it is working in other device or operating system.
My BIOS configure correctly. Any Mass Storage is not
working on my mandriva. I Think it is block or something.
I suspect that someone configure my system to do not detect
mass storage.

Thanks for the reply.

It is still unmounted.
See result after running commands.

Pardon for my post. It is detected, i mean unable to mount.

...but where is its /dev/ device?? If it doesn't have one (as previous posts indicate), then it can't be mounted, at all!

Please remove the drive, reboot your computer, wait for it to finish loading everything, insert the drive, and wait 1 minute. Then, re-run the commands I gave you previously and post their output. It's possible that it was in a "safely-removed" state when you last tried those commands.

ok, so you ran tail -f /var/log/messages but you never plugged the USB device back into the system so you can find the /dev/sdX in order to mount.

Which other system? What OS? And how is it formatted? Have you tried other USB sticks/external drives? Have you rebooted, or restarted the haldaemon? Does it show up under your USB device applet in your GUI?
"Someone"??? Isn't this YOUR system? If it's yours...how could 'someone' modify things to make it not work? If it's not yours, are you sure your user has rights to see/mount external devices?

The Mandriva forums have some ideas:
