hi;

i have a problem in using my usb flash memory ;
this problem occur when installing ubuntu from usb flash only;
after that i can not use my flash and can not mount it and i get the message

Quote:

"Invalid mount option when attempting to mount the volume 'ERAMAX'"

since ERAMAX is my flash volume;
but if i used terminal to mount it manualy by using this command

Quote:

sudo mount /dev/sdb1 /mnt/flash

then i can access my flash for read only Not write ;
so this is my problem

i have another thing that may help that if i put another usb-flash memory while my flash in computer ,i can access the last usb-flash which will be at /dev/sdb2 because the first one at /dev/sdb1
so i can access any usb-flashes except the first flash i put which its device will be at /dev/sdb1

my fstab file is :-

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda5

# /dev/sda6

/dev/sdb1       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

This line:

/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

Tells the system that /dev/sdb1 is either UDF or ISO9660 filesystem which is used by CD/DVD drives. Usually, CD/DVD drive device file is /dev/scd0 for laptops. Removable USB Flash disks should NOT have entries in /etc/fstab file UNLESS you will never remove it again (NB!).
I suggest doing this:
* try commenting the line mounting /dev/sdb1 in the /etc/fstab file
#/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
* Insert your USB Flash disk, it'll be automounted under /media directory
* Figure out the device file for CD/DVD drive (usually /dev/scd0) and replace /dev/sdb1 with it on the /etc/fstab like
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
* Insert a CD/DVD and see if it is mounted as expected.
