 Posted: Tue Feb 28, 2006 12:31 am Post subject: External HDD & vfat. [SOLVED] |
 |
|
I just bought an external hard drive. Its a 250GB maxtor in a enclosure I bought from newegg.
Anyways when I mount it I can't write to it. I can only read from it. I have tried following these guides over at the gentoo-wiki. Even as root I can do nothing. I would just use reiserfs but I have to use vfat as it is compatible with windows.
HOWTO Mount Windows partitions (DOS, FAT,NTFS)
HOWTO USB Mass Storage Device
HARDWARE Using an iPod With Gentoo Linux
here is my fstab
| Code: | /dev/hda1 / ext3 noatime 1 2
/dev/hda2 /ftp/music_l-z reiserfs noatime 1 2
/dev/hdb1 /ftp/music_a-k reiserfs noatime 1 2
/dev/sda1 /ftp/1upload reiserfs noatime 1 2
/dev/sdb1 /ftp/media reiserfs noatime 1 2
/dev/sdc1 /ftp/media2 reiserfs noatime 1 2
/dev/sdd1 /ftp/software reiserfs noatime 1 2
/dev/sde1 /ftp/2backup vfat gid=0,umask=0000 0 0
/dev/sde2 /ftp/xfer vfat gid=0,umask=0000 0 0 |
The external device is sde. I have tried a number of different combonation on the options. defaults, gid, uid, umask, etc...
When I try chown it syas I can't perform the operation on this device. I am always root when I try this whole process.
Any ideas? I'm no moron please don't say unhelpful things like "If you can't figure out basic permissions don't use linux." Because I can most of the time just not on this external drive.

/dev/sde2 /ftp/xfer vfat user,gid=0,umask=0000 0 0
|
Try adding user or users option to your fstab for the /dev/sde* devices you want to be able to mount as non-root as I have done in your example above.
From man mount....
| Code: |
user Allow an ordinary user to mount the file system. The name of the
mounting user is written to mtab so that he can unmount the file
system again. This option implies the options noexec, nosuid, and
nodev (unless overridden by subsequent options, as in the option
line user,exec,dev,suid).
users Allow every user to mount and unmount the file system. This option
implies the options noexec, nosuid, and nodev (unless overridden by
subsequent options, as in the option line users,exec,dev,suid).
|
See man fstab and man mount for more details.

Ahh, perhaps you need to add the "rw" option to each of the lines so you can actually Read and Write to the drive (hence the recomendation to see the fstab and mount man pages I gave).
Here is my /etc/fstab which mounts various drives of different formats..
| Code: |
$ more /etc/fstab
/dev/hda1 /boot ext2 defaults,noatime 1 2
/dev/hda2 none swap sw 0 0
/dev/hda3 / ext3 defaults,noatime 0 1
/dev/hda4 /data ext3 noatime,users,rw 0 0
/dev/sr0 /mnt/cdrom iso9660 noauto,users,ro 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs nodev,nosuid,noexec 0 0
/dev/sda1 /mnt/camera auto noauto,noatime,user,rw 0 0
/dev/sda3 /mnt/fisher ext3 noauto,noatime,user,rw 0 0
/dev/sda6 /mnt/articles ext3 noauto,noatime,user,rw 0 0
/dev/sda7 /home/neil/usb ext3 noauto,noatime,user,rw 0 0

Nope.
"Cannot chown target file '/ftp/2backup/test.zip' Operation not permitted (1)"
Thats the error I get in MC.
If I just copy the file in the terminal using the cp command it goes through HOWEVER it is not accessible. I also cannot chown it.
Thanks for the help so far. |

Hmm I'm not sure what the problem might be but could you post the commands your using and the output of things like...
| Code: |
$ cd /ftp/
$ ls -lh
$ groups
$ more /etc/groups
$ more /etc/fstab
$ more /etc/mtab
|
as that might contain some useful information.
slack
P.S. - Could you use the BB tags to encapsulate things in code it makes it a bit easier to delineate between what your saying and what your trying to type/error messages in the console. |

The last line in this last one looks wrong specificly the noexec (no execute) and nosuid.

Well it looks to me like a permissions problem, if you look at the output from....
| Quote: |
| Code: |
ls -lh
total 9.5K
drwxr-x--- 20 ftpul ftp 1.5K Oct 15 00:08 1upload
drwxr-x--- 2 root root 4.0K Oct 20 16:17 2backup
drwxr-x--- 11 ftpul ftp 288 Sep 21 18:58 media
drwxr-x--- 9 ftpul ftp 232 Dec 19 2005 media2
drwxr-x--- 16 ftpul ftp 368 Jul 21 2005 music_a-k
drwxr-x--- 21 ftpul ftp 488 Apr 16 2005 music_l-z
drwxr-x--- 13 ftpul ftp 344 Oct 1 2005 software
drwxr-x--- 2 root root 4.0K Oct 20 16:17 xfer

You'll see that the permissions on all of the folders are that they are owned by ftpul and the groups are ftp.
| Quote: |
| Code: |
root bin daemon sys adm disk wheel floppy dialout tape video
|
|
Did you run this as root or user? If its as root then you need to log out and try it as user, and unless you are user ftpul then you don't have permissons to do anything with these folders (output from /etc/group (sorry about the typo btw), suggests that your user name is matt).
Thus try the following..
| Code: |
$ cd /ftp/
$ su
$ chown -R root:users *
|
This should be fine as it changes ownership to root, but permissions for users (which your username matt is a member of) to read and write for all directories and sub-directories.
Unless you have any specific intention of executing commands in those directory structures this isn't a problem (all executables should be placed in *bin/ folders).
Fingers crossed it works

Groups run as user, not root. Result:
| Code: | | wheel usb users portage |
Result of "chown -R ftpul:ftp *"
ftpul is the account that should own the directory.
| Code: | | chown: changing ownership of `2backup': Operation not permitted |
2backup is the External drive.
Again thanks for your help. |

Just editied my last message after giving it more thought, have a quick look and see if that sorts it out.
Does the user ftpul exist on your system? Usually when you create users they get assigned their own group, and I couldn't see an ftpul entry in your /etc/group file. That would probably explain a lot of the problems  |

under /ftp/
| Code: | chown -R root:users *
chown: changing ownership of `2backup': Operation not permitted |
What could possibly cause this? This is driving me crazy.
Here is a printout of fdisk on /dev/sde

Hmm, no idea why root wouldn't be permitted to perform chown, you were trying...
| Code: |
$ cd /ftp
$ su
# chown -R root:users *
|
and not trying to chown as matt?
dosfstools shouldn't be necessary, as they are mainly for creating dos filesystems, this is a mount and permissions problem.

I was su'ed into root. I made sure of it.
| Code: |
Disk /dev/sde: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sde1 1 5100 40965718+ c W95 FAT32 (LBA)
/dev/sde2 5101 30163 201318547+ c W95 FAT32 (LBA)
|
Should they be W95 FAT32 (LBA) or just W95 FAT32.
I should also let you know that I created those partitions under windows. |

I'm afraid I'm at a loss then I've no idea.
I can mount external HD's, flash drives and USB camera devices (seen as fat) no probs using the
| Code: |
/dev/sda1 /mnt/camera auto noauto,noatime,user,rw 0 0
|
line in my /etc/fstab, perhaps the only difference is I'm using the 'auto' option to determine file type (both are fat systems). You could tray changing that entry in your fstab file.
Further my mount point is very similar to yours (although you could try changing them to reflect what I have)....
| Code: |
$ ls -l /mnt
drwxr-xr-x 2 root root 4096 Jan 23 08:41 camera
|
You could try deleting the mount point and creating it again. Beyond that I'm at a loss, sorry. |

| I'm just wondering, but why don't you format the drive as NTFS and mount it using captive? I've had numerous problems getting vfat to work, but NTFS via captive has never failed me. |
