Permission Help

[Jeffrey2132]

---

Alrighty, I'm trying to back up my computer and I am having a bit of trouble. Knoppix will not allow me to access my external hard drive and partitions from the internal hard drive. I have looked at the permissions making it say that it's writable but I don't know what's going on.

So here is what I'm trying to copy:
The entire folder:
/media/sda2/home/jeffrey

to
/media/sdb1/jeffs


If you guys can help me out that would rock!

Post the results of

$ mount | grep 'sdb1'

and

$ ls -ld /media/sdb1/jeffs

[Jeffrey2132]

This is from the first command:


/dev/sdb1 on /media/sdb1 type vfat (ro,nosuid,nodev,umask=000,shortname=winnt,uid=100 0,gid=1000)


And the second:


drwxrwxrwx 2 knoppix knoppix 32768 May 20 20:36 /media/sdb1/jeffs

Ok, for starters it is being mounted read-only (ro). You may need to explicitly tell it to mount rw. How are you mounting it exactly?

Also, who is uid 100? You can use

$ grep 'x:100:' /etc/passwd

to find out.

How about gid 1000?

$ grep 'x:1000:' /etc/group

It's the auto detection that Knoppix does. Just clicking on the drives on the desktop...
Here are the commands:

knoppix@Knoppix:~$ grep 'x:100:' /etc/passwd
mysql:100:103:MySQL Server:/var/lib/mysql:/bin/false
knoppix@Knoppix:~$ grep 'x:1000:' /etc/group
knoppix:1000:

post the output of 'fdisk -l' command here.

[Jeffrey2132]

It doesn't give anything as output:

knoppix@Knoppix:~$ fdisk -l
knoppix@Knoppix:~$ fdisk -l

I tried twice.

[devils casper]

you must have root privileges to execute this command.

su 
fdisk -l

[Jeffrey2132]

Aww! Okay:

root@Knoppix:/ramdisk/home/knoppix# fdisk -l

[devils casper]

execute this

su
mkdir sda1 sdb1 hdd1
mount -t    ntfs-3g   /dev/sda1 sda1 -o defaults,umask=0
mount -t    vfat    /dev/sdb1 sdb1 -o defaults,umask=0
mount -t    ntfs-3g   /dev/hdd1 hdd1 -o defaults,umask=0

check sda1, sdb1 and hdd1 folders. check if you are able to write in all those.
