Partitioned external hard disk, write problem

English Hardware
#1

Hi,

I have a usb connected external hard disk. I partitioned it like this:

  1. 100GB FAT32
  2. 400GB EXT3
  3. 250GB EXT3

The problem is that I cannot write (it says I don’t have permission) to the 2 non-primary partitions. I have read somewhere that this is a usb related problem suse has??

Not sure what to do, I didn’t work on OpenSuse 10.1 10.3 and 11.0

I tried as root. Here is my
/fstab:

and mtab:

/dev/sdb1 /media/disk vfat rw,nosuid,nodev,noatime,flush,uid=1000,utf8,shortname=lower 0 0

You help is very much appreciated!

Look here
Suse: HowTo set disk access permissions for Fat32 (VFAT) on a desktop PC

ext3 should be easy enough, just check your settings for /home in /etc/fstab
and use similar for these

Thanks for your quick reply.

Actually, the FAT32 is the only partition that works fine. I’m guessing since it is the primary partition.

The /home partition also works fine, that’s on my main sata disk.

The partitions that don’t work are the non-primary ext3s on my usb harddisk.

Usb sticks work fine, as long as they only have 1 partiton on them :slight_smile:

Any suggestions how to write to the secondary partitions?

I just plugged in the usb disk, and here is my new mtab:


/dev/sda6 / ext3 rw,acl,user_xattr 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
debugfs /sys/kernel/debug debugfs rw 0 0
udev /dev tmpfs rw 0 0
devpts /dev/pts devpts rw,mode=0620,gid=5 0 0
/dev/sda7 /home ext3 rw,acl,user_xattr 0 0
/dev/sda2 /windows/C fuseblk rw,noexec,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0
fusectl /sys/fs/fuse/connections fusectl rw 0 0
securityfs /sys/kernel/security securityfs rw 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
/dev/sdb2 /media/Media ext3 rw,nosuid,nodev,data=ordered 0 0
/dev/sdb1 /media/Paperplay ext3 rw,nosuid,nodev,data=ordered 0 0
/dev/sdb3 /media/OMNI vfat rw,nosuid,nodev,noatime,flush,uid=1000,utf8,shortname=lower 0 0

fstab remains the same. The disks are Paperplay and Media. OMNI wor

I’m not sure. Wait for someone more experienced like mingus725 or swerdna

this section from the tutorial could help:

  • • Change ownership with command: chown -R root:users /mnt/fat32
  • • Change permissions with command: chmod 775 /mnt/fat32

Replace the mount points with yours
eg: /media/Paperplay

Thanks so much.

I did have to use chmod -R.

It works fine now. I’m really happy!!
