USB Memory Key no longer mounts

Sandisk Cruzer Mini 256MB

This is a problem which has just sprung up out of the blue. Fedora Core 3 no longer seems to be able to recognise or mount my USB key. I've had a quick search around the internet and tried a few commands, but it won't seem to mount. When I try to mount manually:

Code:

[root@rei michael]# mount /dev/sda1 /media/usb

mount: special device /dev/sda1 does not exist

I check the currently connected USB devices, to see if it is actually recognised by Linux.

Code:

[root@rei michael]# /sbin/lsusb

Bus 004 Device 002: ID 10df:0100 In-Win Development, Inc.

Bus 004 Device 001: ID 0000:0000

Bus 003 Device 002: ID 06b9:4061 Alcatel Telecom Speed Touch ISDN or ADSL Modem

Bus 003 Device 001: ID 0000:0000

Bus 002 Device 002: ID 043d:0078 Lexmark International, Inc.

Bus 002 Device 001: ID 0000:0000

Bus 001 Device 001: ID 0000:0000

No sign of it. I check the interrupts to see if anything is turning up there.

Code:

[root@rei michael]# tail /proc/interrupts

  8:          1          XT-PIC  rtc

 15:      1676          XT-PIC  ide1

NMI:          0

ERR:          0

I have a look at my message log next. This is the last thing I can think of since no other command has detected the USB device.

Code:

[root@rei michael]# tail /var/log/messages

May 18 15:45:11 rei kernel: usb 1-5: new high speed USB device using address 7

So, I know something is not right here, the connection is timing out. But why all of a sudden over the past couple of days has the USB Key stopped working? Can anyone help me out? I don't want to do a ful reinstall again.

If you havent already, you might consider checking to see if the propper usb modules are being loaded .

command "lsmod"

I had the same problem with my Cruzer on SuSE. If memory serves me correctly the /dev point changed to /dev/sde1. You may want to check that. It appears from your log files the system sees it. You may also try: mount -t vfat /dev/sdxx /media/usb

xx = your variables of a1 or e1.

I always thought you had to tell mount what type of filesystem and your post doesn't contain that either.

edit:
a post just after yours was replied to by esteeven and this is the link in it.

Thanks for that. I know where exactly my USB key is located now, although I still can't seem to mount it. A fdisk check gave me this output:

Code:

[root@rei mnt]# /sbin/fdisk -l



Disk /dev/hda: 78.2 GB, 78257815552 bytes

255 heads, 63 sectors/track, 9514 cylinders

  Device Boot      Start        End      Blocks  Id  System

Disk /dev/sdb: 256 MB, 256900608 bytes

16 heads, 32 sectors/track, 979 cylinders

Units = cylinders of 512 * 512 = 262144 bytes



  Device Boot      Start        End      Blocks  Id  System

/dev/sdb1              1        979      250574+  6  FAT16

so my usb key is located at /dev/sdb1. So I updated my /etc/fstab file as so:

Code:

# This file is edited by fstab-sync - see 'man fstab-sync' for details

LABEL=/                /                      ext2    defaults        1 1

none                    /dev/pts                devpts  gid=5,mode=620  0 0

none                    /dev/shm                tmpfs  defaults        0 0

none                    /proc                  proc    defaults        0 0

none                    /sys                    sysfs  defaults        0 0

/dev/hda5              swap                    swap    defaults        0 0

/dev/hdd                /media/cdrecorder      auto    pamconsole,fscontext=system_u:object_r:removable_t,ro,exec,noauto,managed 0 0

/dev/fd0                /media/floppy          auto    

/dev/sdb1                /media/usbstick                FAT16 user,noauto,umask=0 0 0

so hopefilly all will be well when I try to mount it in the console. However, when I try to, this error appears:

Code:

[root@rei mnt]# mount /media/usbstick

mount: mount point /media/usbstick does not exist

So, any more ideas?

Problem solved. Turns out I made the usbstick directory in /mnt rather than /media. Thanks anyway.

I truely am a n00b at times... ^^;
