Hi,

insmod usb-storage
and after that the usb thumb shoulb be known as /dev/sda1
then do a mount /dev/sda1 /your_mount_point
and everything is done fine :)

if you got other usb/scsi devices on your notebook then you have to use on of the /dev/sd* devices :)

cu

thx for the quick reply, but i c these error now.

when i type insmod usb-storage, i get the following

Using /lib/modules/2.4.18-14/kernel/drivers/usb/storage/usb-storage.o
insmod: a module named usb-storage already exists

and when i type mount /dev/sda1 /mnt/usb i get the following error,

mount: /dev/sda1 is not a valid block device

what am i doing wrong. ooh and the notebook specs are

a sony vaio pcg-z600hek.

i tries plugging the drive on the replicator port and on the port in the nitebook itself , but still it says the same thing :)

what am i doing wrong !

Got It :)
 

Hi again,

i got it working now :D and that really makes me a happy penguin ! hehe. the device was /dev/sdb1 , and now everything works

thx a bunch,

Penguin Power.

Redhat 9 ... When I plug my USB drive in, it mounts it, and picks up the name of the drive 100%.

BUT .. there are files in the drive, and they are not detected.

The drive is formatted FAT

try this
 

Maybe your distro isn't mounting the thumbdrive as FAT. Explicitly specifying the file system type to mount might work. Try this:

mount -t vfat /dev/sda1 /mnt/flashdrive

or whatever your mount point is set to. Also, if you have other usb devices installed, the thumbdrive might show up as a different SCSI device.

lsusb

will show your usb devices. If you have another device installed, you might try something along the lines of:

mount -t vfat /dev/sdb1 /mnt/flashdrive

also make sure that you have the usb-storage module loaded.

lsmod |less

will show you all loaded modules. If you don't see usb-storage then type:

modprobe usb-storage

Try the mount thingy again and everything should be gravy. If you want it to be mounted on boot you can edit your /etc/fstab and add the following:

/dev/sda1 /mnt/flashdrive vfat noauto,user,fat=12 0 0

Good luck.

Hello,
I'm having similar problems with my SanDisk Cruzer 256Mb, I get /dev/sda1 is not a valid block device (this only started after I plugged in that damn drive :mad: , now whenever I plug in a usb device it is in /dev/sdbx, its swapped them over for some reason!)

Anyhow I tried lsusb and I get

linux:/home/rob # lsusb
Bus 003 Device 001: ID 0000:0000
Bus 003 Device 002: ID 0a81:0101 Chesen Electronics Corp.
Bus 002 Device 001: ID 0000:0000
Bus 002 Device 002: ID 045e:006a Microsoft Corp.
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 006: ID 0781:8185 SanDisk Corp. <- my drive!!

does that mean my sandisk is on dev/sda6? I tried mounting that and it came up with the same "sda6 is not a valid block device" :mad:

heya,
as far as i know if your devicde is not sda then it cannot be on the 6'th partition, try using fdisk as follow :

try one of these.

fdisk /dev/sda
fdisk /dev/sdb
fdisk /dev/sdc
fdisk /dev/sdd

one of these should be your drive, if that particular device is not present then fdisk will give you some error, but if not and it gives you a prompt thing then type 'p' to display the partition(s) on your usb drive. :

thse should look like /dev/sda1 or /dev/sda2 or /dev/sdb1 etc ........

then you can mount the desired partition on the usb drive:

mkdir /mnt/usb_drive
mount /dev/sXY /mnt/usb_drive

(where X represents your device : i.e a,b,c or d) and (Y represents the partition you want to mount on the drive ! )

just a side note to quit from fdisk type q ;)

I just tried that and I get

"Unable to open /dev/sdd" etc. for all of them :cry:

I get the following output from dmesg if it helps anyone work out what's going on

Hi dhbiker
 

look it's just a thought,

DO you know for a fact that your thumbdrive works (have you had it mounted and read / writing on other systems, other OS'es?

Regards

Mick

yeah, it works fine in Windows 2000!! I don't understand why linux is complaining, I had my old usb pen working fine :scratch:

I've tried the disc again and I thought I'd gotten somewhere, I plugged it in looked a dmesg and was hopefull. I tried to mount it and the console hung and then the usb drive got switched off (the light on it went out). A little while later the console returned me to the prompt and a bit after that the usb stick got turned back on.

Here's my dmesg output:

Any thoughts?

Maybe I'll give up on SuSE and try something else.....

Hi,

I have some problems when trying to mount a cruzer mini 256 MB using SuSE 8.2, but I've made some progress; maybe this can help:

When I insert the flash drive, the computer makes a sound and the drive's led turns on; for about two minutes, the system tries to recognize it, (I do nothing); then the light turns off and later the same first sound is heard: the system gave up. At that point, I type the following commands:

# modprobe -r usb-storage
# modprobe usb-storage
# exit
% mount /mnt/usb # I added this mount point in the /etc/fstab file
% cp something /mnt/usb
% ls /mnt/usb/dev/hda3 / reiserfs defaults 1 1
/dev/hda1 /windows/C ntfs ro,users,gid=users,umask=0002,nls=iso8859-1 0 0
/dev/hda2 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbdevfs /proc/bus/usb usbdevfs noauto 0 0
/dev/cdrecorder /media/cdrecorder auto ro,noauto,user,exec 0 0
/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0
/dev/sda1 /mnt/usb ext3,vfat defaults,noauto,users 0 0

Of course this is not exactly the way the pen drive is suppoused to work, but this is better than not working at all. I'm still looking for a better solution.

something

My /etc/fstab look like this:
