[SOLVED]Problems auto-mounting External HDD via fstab entry

Hello!
I recently set up TimeShift, a backup tool, and I have it set to store the snapshots onto an external HDD. I would like the program to make a snapshot once daily and to do this I would have to mount the external manually.
So I looked up instructions on how to add an external HDD to my fstab. It worked, I got the harddrive to mount at boot, however it then disabled my belkin usb-hub (which has my mouse and keyboard plugged into it). I ran the following commands to add the external to my fstab...
sudo mkdir /run/media/disco/backup
and then I had to find the path to external by running
mount
found the line I was looking for which was
/dev/sdb1 on /run/media/disco/fcf1f0b0-d756-41d6-a7c8-2ab7d009be2e type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2)
So I edited my fstab to the following
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sda1 UUID=a2ba860f-a990-4c75-879b-1138d941857d
/dev/sda1 / ext4 rw,relatime,data=ordered 0 1
# /dev/sda2 UUID=43fab9a6-904a-4c2e-8362-d2205ef6bbe2
/dev/sda2 none swap defaults 0 0
/dev/sdb1 /run/media/disco/backup auto auto,user,rw,exec 0 0
I reverted back to the fstab that doesn't have the last line, and my belkin usb-hub works again.  I'm just curious if I'm doing something wrong, or if I need additional steps that I am missing.
Any help is appreciated, please and thank you! (:

proper directory for persistent mount points is
/mnt/
The /run directory is used by runtime applications as, say, a temporary working directory usually meant to be accessed by other applications as a way of IPC (unlike /tmp which is used as general dump for mostly private volatile data, temporary caches, etc.) The /run directory is usually a tmpfs meaning it only exists in memory and gets deleted on reboot. This is most likely the reason it didn't work for you.
Also, you may want to change the /dev/sdb1 dev node in fstab to a UUID entry so that there is no confusion in case of different block device node gets assigned to the drive (such as if it gets connected after some other storage drive, being it another USB drive, an SD card, or anything else).

  • [Solved]Can't mount external hdd at boot!

    Hi!
    I'm trying to mount my new external hdd (Lacie USB2) at boot, but without success.
    To avoid random device name (sdx, sdy), I would like to use UUID in my fstab file.
    I've read this wiki.
    I think my configuration is ok, but there's an error at boot saying "Device with UUID xxxxxxxx doesn't exist, can't mount it", or something like that.

    Hi,
    Thanks for your reply.
    But even with /dev/disk/by-uuid/6853-5BA9 in my fstab file, it fails to automount it.
    It says "Special device with UUID=6853-5BA9 does not exist".
    The weird thing is that I can mount it manually without problems.
    (In fact, that's not true, I've the same problem than steven.  May it be a kernel-related problem?)
    Or maybe there's a fault in the rest of my fstab line? (iocharset, guid, etc?)
    In the case of a kernel related bug, how could I downgrade it?
    I've tried with "pacman -U kernel26-2.6.21.6-1.pkg.tar.gz" in /var/cache/pacman/pkg but it broke my xorg server at reboot.

  • Trying to mount external HDD, problems arise

    Been trying to mount my external HD but it's not playing ball. Firstly, I can't work out what my setup is naming it in /dev, partly because I'm getting inconsistent readings of available space on my internal HD.
    If I run
    df
    when the external HD isn't plugged in, I get the following output:
    Filesystem 1K-blocks Used Available Use% Mounted on
    rootfs 7662396 2662828 4615216 37% /
    /dev 1024816 0 1024816 0% /dev
    run 1027740 204 1027536 1% /run
    /dev/sda3 7662396 2662828 4615216 37% /
    shm 1027740 0 1027740 0% /dev/shm
    tmpfs 1027740 8 1027732 1% /tmp
    /dev/sda1 99590 17903 76468 19% /boot
    /dev/sda4 152576072 2634200 142302968 2% /home
    I figured that if I plug it in and run the command again, something new should pop up and I can thus figure out what's where. However, the above reading doesn't even make sense.
    Firstly, there's sda1, 2 & 3. I only have two partitions on my hard drive (one for /, one for /home). I also have a swap. Yet reading the available spaces, there's four different places (going on size); 1027740, 99590, 152576072 & 7662396.
    My internal hard drive is only about 160 gig.
    If I open thunar and view the properties for /, I get the following:
    Size: 106764 items, totalling 128.0 TB
    Free Space: 4.4 GB
    From memory, the partition allocation for / was 10 gig, so the free space reading is presumably correct, but the 128 TB reading is bizarre. My external hard drive is 1TB, so it can't be that it's adding together / & the ex. HDD to get that estimate (if it is, it's worse at maths than I am); plus it gives the same estimate regardless of whether or not the ex. HDD is attached to my PC.
    If I run:
    lsusb
    with my external HDD attached, it registers just fine (OK, it gets the size wrong, but it's better than nothing)
    Bus 001 Device 004: ID 1058:1021 Western Digital Technologies, Inc. Elements 2TB
    Anyone got any ideas about what's going wrong and how I can amend things?
    (this is the first time I've had a Arch setup -previously ran Crunchbang- so I acknowledge that I may just have missed something I should have installed/configured)
    Insights much appreciated :-)

    Ohhh, pmount worked a treat ^ ^
    Any way to get it mount it automatically when I log in?
    mm..I guess you can put it in your ~/.xinitrc file
    but put the line before the DE/WM invocation line.
    so, if you use say, use lxde and have a line like
    exec ck-launch-session dbus-launch startlxde
    in your .xinitrc,
    put the 'pmount device' line before that.
    Edit. if u want to put it in ~/.bashrc, you'll have to start a bash terminal at least once after you log in to get it mounted.
    Hmm, pmount isn't working as well as I thought.
    It won't let me transfer files from my hard drive to the external; says it isn't permitted. If I open thunar as root and try to change the groups read/write permissions it says the operation isn't supported (though I myself have read/write access apparently :s).
    Edit: Typo
    pmount is just a wrapper, it calls the standard mount program to actually do the work, without the need to have an entry in fstab. Let's first make sure that you can mount and use the drive with the standard old-fashioned mount. When we get that to work, switching should be just a matter of using correct pmount options or doing some minor tweaks.
    From what you linked, I assume you are using ext filesystem, which should make things a lot easier. If you're using something else, you need to let us know.
    First things first, lets start from the beginning. Umount the drive and set permissions on the empty directory you're mounting it into back to root (or just remove it and recreate it as root). This is not essential, just doing that so we know the current state of things.
    Second, mount the drive with simple   mount /dev/sdx /mnt/mountpoint   Obviously you need to change the device and mountpoint to whatever's appropriate. This *should* work. Logged in as root, try to create a directory inside, and for example copy something into this new directory, to make 100% sure that the drive is correctly mounted. If you get past this point and everything works, then this all is most likely just a case of botched permissions. You can't write into it as a user yet, but we now know that it can be correctly mounted.
    Third, find out your user uid, and your primary group gid. Simply type 'id' into terminal logged in as regular user you want to mount the drive with, if it's the only user you created shortly after system installation, then most likely your uid will be 1000 and gid of users group will be 100. Now umount the drive, and re-mount it with running as root   mount -o uid=1000,gid=100 /dev/sdx /mnt/mountpoint   Again, change everything as appropriate. You now should be able to write new files and directories onto your drive as your normal user. You still may not be able to edit files already stored in if permissions were set wrong, but that can be changed, as we discussed before.
    If this all works, then you can use your drive without any problems, and one line in your fstab will mean that you can mount the drive as user without even needing pmount. Please verify everything works first, if it does we can help you with that as well if you need it. And sorry if I'm being too thorough, just trying to avoid any mistakes
    edit: to avoid any confusion, this is more or less a test. When mounting ext partitions you shouldn't have to set things like uid, gid or umask. Those options are primarily meant for filesystems which don't use this kind of permission setting, like vfat or ntfs. But it should move us a little bit further.

  • Mac won't mount external HDD since 10.8.4 update

    Hi All
    I'm fairly new to Mac (3mths) so still finding my feet...hopefully someone is able to help me here!
    Hardware:
    MBP 2.7Ghz running (now) Os 10.8.4
    WD HD5000D032-000 (the old drive)
    3TB WD Red (the new drive)
    Solutions tried to the problem (described in detail below):
    - restart Mac
    - restart eHDD
    - different USB and power cables for eHH
    - different Mac(mini)
    - removed eHDD from stock housing and used SATA docking station
    - bought new HDD and used with SATA docking station
    Now to the detail of my problems:
    I've had a WD 500GB external HDD for about 8yrs. Formatted FAT32. Used with PC/Win laptop no issues.
    Switched to Mac and no issues at all. However after a recent trip to Japan I plugged in the HDD to back up all the photos and vids I'd taken (I took my Mac with me to download off the the various SD cards,etc), the HDD plugged in and booted fine as normal and file transfer was initiated. The folder was large (don't recall how much but a few GB at least). Everything seemed to be progressing fine so left both Mac and HDD plugged in and carried on watching tv. Noticed a few mins later that an error message had popped up saying disk could not be found (or something similar).
    HDD was no longer visible. Therefore I unplugged and reconnected and.... nothing. I can see the HDD in Disk Utility but it's not mounted. Options to verify/repair disk are greyed out. At this point I tried using different cables and USB ports and still no improvement. I've also tried restarting both Mac and HDD.
    A few hours of reading forum posts suggested the HDD housing may be the culprit as it was quite old and prone to failing. As I'd tried all else, I went out and bought a SATA docking station and removed the HDD from its stock housing. This yielded the same results - I can see the HDD clearly in Disk utility but can't mount or verify/repair.
    I then tried plugging into mate's Macmini running and older Osx and this time, the verify/repair options are available. Tried them and result was disk could not be repaired by Disk Utility. I still couldn't mount the drive and access any files though.
    I had been planning on setting up a NAS anyway so ordered a new 3TB eHDD (WD Red) which arrived yesterday. I plugged it in using the docking station ni order to format it to FAT32 so that I could at least download my data from my Mac (and then subsequently look to recover all the data from the old eHDD) but the option 'MS-DOS File System' isn't available in the drop down in Disk Utility/Erase.
    All the steup guides on formatting HDDs using Mac suggest that I should have this option in order to format as FAT32. All I see are 3 types of  'MS-DOS (extended)' and 'exFAT'.
    The twist:
    All this time I just assumed that it was the hardware acting up but the fact that the new HDD isn't recognised properly either made me wonder. I remember updating the OS to 10.8.4 whilst I was away in Japan and connected to wifi. I presumed that any update that was pushed down to me was good to go - could I be wrong??
    I've also noticed that my wifi sometimes takes a while to connect / disconnects by itself and skype repeatedly drops calls. From more reading around, I see that these are some issues people have experienced since updating to 10.8.4.
    So could my HDD issues be being caused by 10.8. 4 as well?!
    I'm out of ideas so now wondering whether I should try and roll back the 10.8.4 update but I've not idea whether this is safe/easy to do, etc...
    Any help would be VERY much appreciated!!
    Thanks in advance!

  • External HDD via eSATA or internal HDD - which is fastest?

    I am thinking of putting a fifth HDD in the optical bay of my mac pro. It looks a little bit fiddly to install (brackets, routing cables etc). I also have a Sonnet Tempo E4P SATA card. Is aan external HDD connected vis eSATA as fast as an internal drive?
    Also, if I have two external drives set up as RAID 0 and use these as a scratch disk for photoshop will they be faster than a single internal HDD?

    I also have a Sonnet Tempo E4P SATA card. Is aan external HDD connected via eSATA as fast as an internal drive?
    Yes - an external HD configured with the E4P is just as fast as an internally mounted hard disk. The advantage provided by the eSATA host adapter is that the HD attached to it is now hot swappable. The internal hard disk is not.
    Hot swap is great for backup sets and adding storage as needed.

  • Mounting external HDD

    I am new to macs in general and have recently gotten the intel iMac as well as the Western Digital Studio Edition externall HDD.
    While I am not having any of the many problems I find others are having from reading forum posts concerning this particular drive, I did want to ask a question as I am not sure if my trouble is the drive itself of my lack of knowledge concerning macs.
    When using apps such as Carbon Copy Cloner 3, I find that the program is not able to find the external HD when no users are logged onto the mac. However, the documentation for the program states that no user is required to be logged in for it to run. Should CCC run scheduled backups to this drive when no one is logged in? After a user log off is (should) the external HD still mounted?
    Thanks,

    Wow, thanks for the quick reply!
    Ok, the drive is connected and on and the computer is scheduled (under system prefs) to wake at a time that is at least 10 mins before the scheduled CCC backup.
    Under the CCC docs (particularly at http://www.bombich.com/software/docs/CCCHelp/content/scheduler.html under "What if?...") I understood it to mean that no users had to be logged on for the backup to occur.
    As you did not further clarify the mounting of an external drive in general, am I to assume that after having been logged in and seen that an external HDD is mounted, when logging off it will remain mounted if not ejected first? I'm just asking regarding the operation of a mac in general.
    Thanks again,

    Does anyone have an idea on what to do with this problem?

    You do perhaps have to include the partitions in the fstab file. This could help you:
    http://wiki.archlinux.org/index.php/Fstab
    You want to mount /dev/sdb1 (ext3) and /dev/sdb2 (ntfs) to any folders preferably in /mnt. You will have to create them as root. Have a look at
    ls -l /dev/disk/by-uuid/
    Maybe you want to mount from there as this method is not dependent on the order and usb port number you plug it in. For ntfs you can choose
    noauto,uid=1000,gid=100,umask=027
    as mount options in fstab if your user-id is 1000.

  • Problems with seagate external hdd

    Connect the External HD directly up to one of the iMac's and follow the Formatting and Partitioning instructions in Ken's article: (but note that doing so will erase the data on the drive)

    I have an external hard drive with all my music on it, and I want MPD to play this music. Now I was wondering how best to mount my external, such that MPD can actually access the music.
    I was told to create an fstab entry with the UUID of my external to have it being mounted to a fixed spot. But this only works during boot up, correct?
    What should I do, if I plug in the external after boot up? Is there a way to have it automounted to the same fixed spot as defined in fstab (maybe even using fstab)?

    As iBertus mentioned, you can use the automount features of different desktops. XFCE includes the Thunar file manager which can also be used in other lightweight desktops.
    If on the command line, pmount will let you mount the drive as a normal user, and without any fstab entries. This command will mount USB device sdb1  to /media/Stalafin.
    pmount /dev/sdb1 Stalafin]
    The cool thing about pmount is that if the drive/partition is encrypted with LUKS, you can throw other options at it and it will decrypt and mount at the same time.

  • Problems with my External HDD. Loosing space?

    I am new to Mac.
    I just bought a new iMac, and a 2 TB WD My Passport external HDD where I am backing up all my files collected from previous works done under Windows.
    In the 2 TB HDD I have created 3 folders: one has 546 GB, another has 200 GB, and the third 0,2 GB (200 MB).
    So the total should be something like 800 GB, and therefore the available space in the HDD should be in the range of 1,2 TB.
    But when I look in Properties, it tells me that the Used space is 1,3 TB, and that the Available Space is 0,7 TB.
    How can this be?
    I have looked into another articles and all of them say that I should not have to Defrag (I had that doubt because I copied info into the HDD and then I deleted it, and so it could be marked as used).
    So, if that is not the case, what can be happening?
    What should I do to recover the rest of the space?
    Thanks

    You are still under warranty and/or have AppleCare.  Call them.  Let them deal w/it.

  • Problems with 1TB external HDD

    I have two external HDD, one a LaCie 2TB and one a Maxtor Basics 1.5TB. Both devices come formatted as FAT32. I have tried reformatting using Disk Utility to Mac OS Extended but the process fails on both devices, whichever of my iMac I use. The only thing I can then do is re-partition them as FAT32 again.
    Equally frustrating, the devices are not visible when I try to access them from other machines on the network whereas other drives connected to the same machine are fully visible.
    Is there a size limit for formatting using Mac OS Extended or something?
    Any suggestions of how I might at least get them visible for sharing across the network - even if they have to stay as FAT32 drives?

    Hi Brian
    Connect the External HD directly up to one of the iMac's and follow the Formatting and Partitioning instructions in Ken's article: (but note that doing so will erase the data on the drive)
    Ken Stone's article: http://www.kenstone.net/fcphomepage/partitioningtiger.html
    It's sounding more like your trouble is with network sharing than format, if so have a look
