Can not mount drive
 

Guys, pls help!

THe problem is: my usb stick is only seen under lsusb:

Bus 001 Device 007: ID 090c:3000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.)

after
grep SCSI /var/log/messages

it is apparently /dev/sdb
but it it can not be mounted, it cannot be seen

even under XP it only shows F drive and says plug it in

gparted etc don't help.

Any ways I can recover it or is it dead? like physically dead?

Are there files on the drive that are important or you don't want to loose?

when you say gparted didn't help, what did it report? Did it say there are no partitions on the drive at all or it didn't recognize the drive as even being present?

What does the following command output? (Execute it as root with the USB stick plugged in):

fdisk -l

I don't care about files on it....do not need to restore anything

it keeps on searching tho doesn't see/show anything

Any ideas? Or the usb stick's dead?

P.S. it happened after deleting all the files from Thunar(under root)
even extra .Trash001 folders


No physical damage, didn't drop it or anything like that

Look at the output of the dmesg command. What are the errors associated with the drive when it is plugged in? Not enough information to tell but it could be physically dead.

dmesg |grep -i 'SCSI device'
grep SCSI /var/log/messages

i'm not that technical, but can it break down by just deleting files....(incorrectly tho, but still....can't be "filesystem" reformatted/re set etc ?)

Please don't grep the output, give us the complete output that is generated when plugging in that device.

what happens when you try and partition /dev/sdb?
Or, what happens if you just create a raw filesystem on the entire device - e.g.

OK, as we can see the disk is recognized as /dev/sdb, but there seem to be now partitions on it. Please post the output of started as root.
