Hi, I just bought a 400Mbyte usb disk.

My OS is Ubuntu version 5, I've recently done the updates to it.

My computer is a Sony VAIO PCV-RX270DS that I bought in 2001, with
about 400Mbytes of disk and the usb port is USB 1 (that manual doesn't
say which USB version because I think USB 2.0 wasn't out yet). The
disk is connected through a hub.

The drive is a 400GB Simpletech drive. The specifications make it
clear it's USB 1.1 compatible. All the online technical support
assumes you're on Windows.

When I turn on the disk, it appears in the /media directory by the
filename ' simpletech ' (not spaces before and after the name). The
fstab entry that appears is

/dev/sda /media/usb0 auto rw,user,noauto 0 0

If I cd to /media and do 'ls -ld \ simpletech\ ', I get
dr-x------ 1 wulluw wulluw 4096 2007-02-20 10:25 simpletech
if I go into that directory and do 'ls -la' I get
total 8
dr-x------ 1 wulluw wulluw 4096 2007-02-20 10:25 .
drwxr-xr-x 7 root root 4096 2007-07-04 14:20 ..
dr-x------ 1 wulluw wulluw 0 2007-02-20 10:25 System Volume
Information
if I try 'touch a' it says
touch: cannot touch `a': Read-only file system
if I try 'sudo touch a' it still says
touch: cannot touch `a': Read-only file system
I cd back to /media
$ chmod +w \ simpletech\ /
chmod: changing permissions of ` simpletech /': Read-only file system
$ sudo chmod +w \ simpletech\ /
chmod: changing permissions of ` simpletech /': Read-only file system

Why is it saying the filesystem is readonly when /etc/fstab clearly
says it's rw? What do I have to do to get the disk mounted rw? A
400GB readonly disk with nothing on it isn't very useful.

Any help would be appreciated.

oops - I meant my computer has about 400MB of ram, not disk.

My guess: the drive is formatted ntfs and the "auto" in the fstab entry
is causing linux to load the ntfs driver (rather than ntfs-3g). The
drive will be painfully slow at usb 1.1. usb2 pci cards are cheap and
do a great job.

What kind of filesystem did you put on it when you formatted it?

OK, how do I fix the fstab entry to make it RW?

I did not format the drive. I just bought it, brought it home,
plugged it into the USB hub and turned it on.
How would I go about formatting the drive? I would want the drive to
be also readable if I hook it up to a windows machine.

I would like to put in a USB 2.0 board, but I absolutely, positively
don't want to make any hardware changes to my box until I'm able to
back up.

In the past, I would back up on CD-ROM using K3B. Then suddenly,
probably as a result of an upgrade, neither K3B nor the CD-ROM Creator
software are able to find my CD burner. Here's my fstab:

$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/mapper/Ubuntu-root / ext3
defaults,errors=remount-ro 0 1
/dev/hda1 /boot ext3 defaults 0 2
/dev/mapper/Ubuntu-swap_1 none swap sw
0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/hdd /media/cdrom1 udf,iso9660 user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
/dev/sda /media/usb0 auto rw,user,noauto 0 0
$
$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/Ubuntu-root

/dev/sda1 390708800 77912 390630888 1% /media/
simpletech
$

but I don't think upgrading to a 2.0 port is going to change the
permissions of the disk. I think all that would be accomplished by
upgrading to USB 2.0 would be to change my slow 400GB readonly disk
with nothing on it to a fast 400GB disk with nothing on it.

If you did not format it the best you might have is a Windows file system so it
can advertise plug-n-play. If it has no filesystem then you obviously cannot
write to it.

What I believe to be a complete description is here.
http://www.giwersworld.org/computers...b-drives.phtml

The general format command is this. It may be a place other than sbin on Ubuntu.

/sbin/mke2fs -c -j -L 320 /dev/sdX1

Read the article to figure out what X should be. It's easy.

I want to make the article complete so let me know how it goes.

If you want it readable by Windows you will have to create a windows file
system on it with windows and set your fstab entry to mount it as vfat or
whatever. I have not done that in so long I do not remember how to do it. If you
just want primitive access google for a program something like lnxread.exe or
lxread.exe which will copy a file from an ext2 or 3 partition to vfat.

If it was advertised as plug-n-play it should have come with a Windows file
system.

First let's confirm that your external drive is formatted ntfs:
$ sudo fdisk -l /dev/sda

Yes, it's ntfs. So try mounting it using the ntfs-3g driver:
$ ntfs-3g /dev/sda1 /media/usb0

If successful, you finally have write privilege.

If not, you need to install that driver. I don't use Ubuntu
so don't know the details. Once installed, change fstab to:
/dev/sda1 /media/usb0 ntfs-3g rw,user,noauto 0 0
Note that it's sda1, not sda.

I agree that a recent backup promotes sanity. Doing it at
12megabits/sec will provide time to clean the garage, etc.
It will make you appreciate usb2.0 later. You'll see.
