Default Question on Permission for External Hard Drive

Hello Everyone,

I've been playing with Slack 9.1 for a couple of weeks and I am fine
tuning the set ups for my hardware devices. I'm new to Slack and
Linux and this is the first time I've installed an OS so please be
patient!! I'm having lots of fun learning though...

I have an Iomega external hard drive that I want to use for back up.
I have it installed with no problem, but only the root user can write
to it. My fstab file is as follows:

/dev/hda2 swap swap defaults 0 0
/dev/hda3 / reiserfs defaults 1 1
/dev/scd0 /cdrom iso9660 noauto,user,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,user,rw 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

/dev/sda1 /mnt/flashcard auto auto,user,rw 0 0
/dev/sdb3 /mnt/iomega ext3 noauto,user,rw 0 0


And I have set the permissions for /dev/sdb3 to 777 (I am the only
user on my system). /dev/sdb3/ points to the only partition I am
using on my Iomega drive. Why am I not able to read, write or
transfer files from the drive as a normal user? I can do it as root,
but not as "lucinda". And I can mount the drive as "lucinda". Also,
I've set up permissions for my compactflash card drive the same way
and I can r/w with no problem as a normal user for that device, but
why not for my Iomega?

Also, I've managed to enable the scsi emulation for my cdrom, so I am
able to get k3b and xcdroast to work with no problem, but is there any
way to write directly to the cd rom without using these programs? For
example, can I not drag and drop a file from my desktop to the cdrom,
or do I always have to go through cdrecord? Or is that just the way
Slack/Linux is set up?

Thanks for your help,
Lucinda

Setting your hard drive partition to 777 is still a bad idea. Fix that.

What are the permissions on /mnt/iomega?

I have also set the permissions to 777 on /mnt/iomega to see if it
would work, but it still doesn't help. I'm not sure what to try next.
What permissions would you put on /dev/sdb3? What is the
conventional wisdome for devices?

Hi,

1) have u try setting the fstype to auto (autodetect) rather than ext3?

2) if your last mount for that drive is using root, I suggest you detach
then attach the device, reason being that all permission on that drive will
becomes only accessible to root, you will have a permission denied error
even if you managed to mount it successfully. and it doesn't matter if your
have set the permission to 777 for the device, during mount time, the
permission will change depending on the environment.

good luck.

And everything works as root, but not as a normal user? That's very
unusual, and I'm not sure what you've done to create this problem. Have
you tried creating an image file of the drive's contents using "dd"? If
you can do that, try loopback mounting it and see what you get.
Warning, that image could take up a hella lota space.
