usb memory stick problems

[alex stacey]

hello,

i'm completely new to knoppix but am using it to try to recover some files from a corrupt hard disk unto a usb memory stick.

the usb device appears on the desktop as "Hard Disk Partition [sdc1]" and it will not allow me to copy anything onto it. i get the error message "could not write to /mnt/sdc1/blah.doc"

any ideas on what might be going wrong here??

thanks in advance, alex

btw. i'm using the latest version of knoppix

if anyone has a similar problem, here's what i did

ru (to get to the root)

then

mount -o remount,rw /mnt/sdc1

then it worked

Hi, I'm doing the same thing and trying to recover some files and put them on a memory stick or trying to burn it. I'm running a Dell laptop and it doesn't even have "Hard Disk Partition [cd1]" on the desktop for my USB drive. I have connected a cd burner, but when i wouldn't even let me access it. do you know how I can fix this?

what kind of interface to the burner? scsi, usb, firewire, paralell (printerport on a PC)?
the usb stick might be called ubX or sdX (where X is a number from 1-9 iirc) .
and you might mount it with comand below.
first we assume your drive is ubX

mkdir /mnt/ubX

sudo mount -t vfat /dev/ubX /mnt/ubX -o rw
now we asume it is sdX

mkdir /mnt/sdX

sudo mount -t vfat /dev/sdX /mnt/sdX -o rw
this should work in 90% of cases.
to find what your stick is called perhaps

dmesg|grep usb might help or
fdisk -l
these tewo comands will list a bunch of outputl look for lines like this (from my computer after i incert a usbstick)

dmesg|grep usb
...
usb 1-4.3: new full speed USB device using ehci_hcd and address 4
usb-storage: device found at 4
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete
and

fdisk -l
...
Disk /dev/sda: 65 MB, 65536000 bytes
50 heads, 32 sectors/track, 80 cylinders
Units = cylinders of 1600 * 512 = 819200 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 80 63984 6 FAT16

these two qoutes are somewhat shortened, you most likely get some more lines.

hope this helped you
