Force mount external NAS drive

I am runing OS X 10.8.4 on my iMac 20. I am using Time Capsule with an external Sysco Lynksis NAS200 storage device (2-500 Gb Western Digital) in Mirror mode. The NAS200 started showing signs of failure, so I started moving data off of the drives. I was successful in copying/moving some files, but the NAS controller is now dead, but disk utility still recognizes the volume. However, a repair and verify disk only produces the "dirve is corrupt, copy your data off" message. Disk utility, of course will not mount the drive, so I have resourted to a terminal session. Here is what I have tried so far:
1. mkdir /Volumes/NAS200
2. cd /Volumes
2. When I do an ls, the NAS200 shows up. (empty as expected)
3. mount NAS200 produces the error, "unknown special file or file system"
Is there a way to specify the file type or use a wild card to get around this? If I can mount the morrored drive, the rest of the day should be read only for a copy command. Is the right thought process?

Continuing with the previous post, I did a restart, but the drive would not mount in disk utility. Here are the diagnostics:
Verify and Repair volume “disk5s2”
Checking file systemChecking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Missing thread record (id = 2)
Incorrect number of thread records
Incorrect number of thread records
Checking multi-linked files.
Checking catalog hierarchy.
The volume could not be verified completely.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
This error message is useless if you cannot get the drive to mount and read its contents.
Does anyone have any other suggestions? I am running out of options.

Using external NAS drive for Time Machine and multiple Macs

I just installed an external NAS drive from OWC's sister company Newer Tech. It is 500g with ethernet and usb2.0 connections. It works very well with easy setup with Time Machine with no hassle.
However, in very fine print that I missed in the ad, it supports 20 computers but not for Mac only for PC. OWC customer service said I could return it but I'll keep it anyway since it works well but only for one computer at a time in read/write mode.
Anyone know of a way around this? Are there any drivers from other vendors that would allow this to be used with the multiple Macs on my home network?

Very doubtful, but even if there is a workaround, you do not want to take that kind of risk with your backups.
See the pink and yellow boxes in #2 of [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

Best way to import large CD collection to external NAS drive using iTunes

I am planning to re-import a large CD collection to an external NAS drive with iTunes. Previously I imported using a WAV encoder, but now realize that none of the music was tagged and attempts using a tag from file name script proved unsuccessful.
Can anyone advise me on the best method and codic to do this with iTunes? I was planning to use either AAC or MP3 set at 256 or 320kbps. Both of these encoders, I am being told, will hold the ID3 tag. Any other recommendations on this process is welcomed.
Also, once I have the music imported to the network drive, how do I get the itune library to be recognized on another computer on the network (not the computer that was used to import)?

All of the iTunes compatible formats will accept tags, except for WAV. Most people nowadays use either AAC or MP3 at 256 kb/s. But if your ears and your audio setup require the extra fidelity of a lossless format, go with Apple Lossless or AIFF.
Before you start ripping, go to Edit > Preferences > Advanced, and set the iTunes Media folder location to the NAS. Then any files that you rip from CD will go straight to the NAS.
Also, once I have the music imported to the network drive, how do I get the itune library to be recognized on another computer on the network (not the computer that was used to import)?
iTunes does not have any folder watching capability. Once the files are on the NAS, you can manually go to another computer's iTunes to add them (File > Add Folder to library) or you can get 3rd party folder watching software such as iTunes Folder Watch.

Erasing duplicates with ITunes songs on external NAS drive

My home network includes:
-PC Dell Dimension 9150
-Buffalo NAS Drive Linkstation 1Tb with all iTunes music
-PS3
My question: in order to be able to read my iTunes music on my PS3, I exported all of it on my external NAS drive. All songs are duplicated and I would like to clean my library. However, since the songs and the library are on the NAS drive, I can't use the function "Erase duplicates" on the File menu, it is not reachable. Any idea?
Thank you !

Just to add an extra twist...
I moved the full iTunes library back onto my desktop iMac. Then I tried to connect iTunes to that library. And the same thing happened.
Only the same limited list of songs appeared in the iTunes window.
Could this mean that my iTunes library is somehow corrupted? Or is it just missing some file that links up to all the songs?
More to the point, does anyone out there have any thoughts on this?

Mount external hard drive on boot

I have a Mac mini run on SL, I want to set it up as a samba server with a external hard drive which formatted in NFS format.
I tried to write a plist in LaunchDaemons to call a script to mount the hard drive, but it does not work.
Here is my plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.kg.mount</string>
<key>RunAtLoad</key>
<true/>
<key>ProgramArguments</key>
<array>
<string>/System/Library/script/com.kg.mount</string>
</array>
</dict>
</plist>
It get loaded at the start, if I user command 'launchctl list', I can see the service is loaded, but the disk is not mounted. If I run the plist manually after boot, the disk will be mounted.
Does somebody know how to mount a disk at boot time?
Thanks

The OS automatically mounts storage devices when they come online. If that doesn't happen, you need to fix the problem.
First back up the disk, if you haven't already done that.
Get rid of the script and the launchd item. Unload it first -- I assume you know how to do that.
Launch Disk Utility and select the "EX" volume, then run "Repair Disk." If any errors are reported, repeat until there are no more.
If the disk is now mounted, unmount it. Check the /Volumes directory for any empty subdirectories named "EX", "EX-1", or some such. If present, delete them.
Unplug the drive, then plug it in again. If it still doesn't mount, plug it into a different port (if it's USB.) If it still doesn't mount, try it on a different Mac.

Mount external Hard drive in Single user mode

Do any know how to mount an external hard drive in single user mode:
I've issue the following command:
/sbin/mount -uw /
mkdir /Volumes/ex1
/sbin/mount_hfs /dev/disk2s3 /Volumes/ex1
(I've checked my external hard drive using df -k showing the device is disk2s3)
Result:
Permission denied

I seem to remember the "Permission denied" or "Device busy" coming up in some situations but not others when attempting to mount drives at this early stage in "single user" mode...
It might be worth trying to run:<pre>sh /etc/rc</pre>This is actually present among the "Tiger" messages in "Single User" mode, as the procedure to continue booting but remaining in "single user" mode. Indeed, it seems to start up the usual "services" like starting disk arbitration (so you can eg. use 'diskutil' to repair permissions, or loading "NetInfo" so you don't need to work in '-raw' mode - in the past, people had posted complicated procedures for doing these things manually.
After running the 'rc' script, try creating your mount point and and running 'mount_hfs' as usual...

Cannot mount external USB drive with FDisk_partition_scheme

Due to some recent mac issues in my lab, we updated one of the computers to Maverick 10.9.4 from Snow Leopard 10.6.8 yesterday. Anyhow, this seems to have erased the ability of the mac to read or mount several identical USB drives with the NTFS format (WD My Passport Ultra 500GB USB3.0). It could do it yesterday when it was OSX 10.6.8, but not today (OSX 10.9.4). The drives still work fine on other OSX 10.6.8, Windows 8.1 and Ubuntu 14.04 computers (this is appears to be a problem with the Maverick 10.9.4 operating system itself, rather than the flash drives which work flawlessly with every other computer I've tried). I want to remove data from the computer to create backups on the USB drives (no, I don't want to create an online backup or buy a new set of USB drives).
diskutil can see the drives, but cannot verify or repair them as they lack a GUID (GPT) partition scheme. I'm assuming this is the root of the problem. Manually mounting the drives does not work. Installing the ntfs-3g driver also did not work (I was using this to write to the NTFS drives until we upgraded OS's). Installing the WD Passport drivers for OSX also did not work. How do I get the mac to mount these drives?
I could reformat one USB drive and then copy to the others, but this would be extremely inconvenient and take days of copying files back and forth (and would prefer to fix the mac rather than go through this with every NTFS drive I own). If I did this, the FAT32 hard drive format would not be suitable, as format is unable to handle the extremely large sequencing datasets I need to transfer. I'm not super familiar with hard drive formats, but in the event we cannot get Maverick to actually work could someone possibly suggest a format able to handle large file sizes (the largest file I need to move is ~60GB) and be compatible with Windows 8.1 / OSX 10.9.4 / Ubuntu 14.04 as well?
Another workaround I thought of would be just to install an Ubuntu partition on the mac and get the files off through the Linux install. Which is also inconvenient, but would probably be faster than trying to reformat the drives and copy everything over onto them again given the amount of data I want to transfer.
Unrelated, but is there any way to view files and folders in the OSX root directory besides through Terminal? It seems like this functionality was also removed when we "upgraded" from Snow Leopard. (At this point, if it were up to me I would wipe all of the macs we own and replace them with Ubuntu... even the most minor of tasks always require some sort of workaround with them... at my wits end here ).

Yeah this definitely appears to be a problem specifically with this mac. It's been having all sorts of weird problems lately, and we figured that upgrading to Maverick might fix them (but instead we got new problems).
To give an update on this, I ended up reformatting one of the drives to HFS+ and disabled journaling. It now recognizes the drive again, and I'm pulling the files off that way. I looked at exFAT, but it looks like HFS+ has much better Linux support (Windows is read-only but that's only a minor annoyance, as the algorithms to process the data only run on UNIX machines anyways). It's a shame I couldn't keep using NTFS (had to copy over literally EVERYTHING again...) but whatever. Again, no solution for the issue (where this mac can't read NTFS drives).
@rkaufmann87 - To give a bit more explanation, we recently had to disable online backups because apparently the sheer amount of data causes Time Machine to freeze the computer and fail every time it has a scheduled backup (original issue we thought that upgrading to Maverick would solve... didn't work). The hard drive has been having a lot of issues when it begins to reach max capacity as well. So I am pulling off all of my files to external hard drives and deleting the local copy before we attempt to back up online again. And the data would probably take me a year and a lot of money to recreate (for the curious, it's high throughput sequencing data). I'm choosing not to take any chances as a result.

Proper way of mounting external hard drive - fstab rules?

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.

Sparse bundle mounting from NAS drives very slow

I have an unusual problem, where one of my user accounts has recurrent trouble mounting large sparse bundles located on NAS drives. The sparsebundles are hard drive clones, 200-250GB sized. NAS connected by gigabit ethernet.
On trying to mount an image with Finder, there is a pause, lasts 2-3 minutes, then the image mounts, and quite often Finder then goes unresponsive. Relaunching Finder then seems to fix the problem, at least temporarily....
Unmounting the sparsebundles takes 2-3 minutes also....
Two other user accounts I have, one on same hard drive as the affected one, work well, the same sparsebundles mount/unmount instantly....
Yesterday deleting Finder prefs fixed the problem, but then today the problem was back.
This is obviously a Finder issue, connectivity to the NAS in question is fine for other files, even for a 300GB .dmg image, just sparse bundles seem affected....
Any ideas?? It's driving me nuts now!

I too am having this issue. Intel / 10.5.8 attached to an SMB share from Ubuntu Linux.
I ran a test of various image types, and while Sparse Image works, Sparse Bundle fails. Here are my logs. Happy to do some testing and log posting if anyone has a test theory to try.

Trouble mounting external hard drive

Hello,
I'm having a problem with my external hard drive (formatted hfs+). While the hd was connected to a computer running ubuntu, the computer crashed. Since then the drive is read-only on ubuntu and won't mount at all on mac os x 10.4.
I've tried repairing the the drive with disc utility, and get:
Invalid sibling link
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
I've also tried running fsck_hfs in the terminal, with no luck. when I type:
fsck_hfs -fy /dev/rdisk1s2
I end up with:
** /dev/rdisk1s2
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
Invalid sibling link
(4, 16531)
** Volume check failed.
I also tried -r but it didn't work either.
So before I back up and reformat the drive, does anyone have any suggestions?
Thanks.

Appears you need a stronger utility than Disk Utility. Sounds like you have directory damage.
The following are a few forum favorites. You must use the versions that are compatible w/your OS system & keep the utilities updated to avoid damaging/harming/trashing your system.
DiskWarrior
Highly recommended for *directory damage* repairs.
TechTool Pro
Multi-functional utility.
Drive Genius Multi-functional utility.
You will need to make your own decision on which to purchase. Read up on them on their websites because each does something a little different.

Mount external hard drive

My Mac crashed and when I restarted it I can only see 1 partion of my external hard drive.
I have tried going to disk utility to load the partion but it wont load
Please can anyone advise how to mount an unmounted drive?
This is what is in the log

An error (19) occurred while copying.
Mount of “Mac” succeeded
Mount of “Mac” succeeded

An error (2) occurred while copying.
Thanks for your help

If this is not the drive you are booting from, you should be able to run Disk Utility's "Repair" function without booting from the CD. Otherwise, boot from the Installer CD, but do not install. Instead, choose Disk Utility from the Installer menu.
Since you booted from another Drive or the Installer CD, when you select the drive, you will be able to use the "Repair" button. Run it repeatedly until there is no change between successive passes, then (if Mac OS X is present on it) run "Repair Permissions" once. Report any unresolved errors from "Repair" here. "Repair Permissions" chatters on forever about nothing, and its messages can generally be disregarded.
Error (2) is a Bus error. It is a very serious error, which should have crashed your Mac. Error (-2) is an invalid queue element, which can be caused by directory damage.
Error (19) can be caused by a damaged System Folder. Error (-19) is a color-manager error.

Force mount nonexistent dvd drive

Hello all, So intro: The other day I pop in a dvd backup that has some files I need, now the dvd is not readable, no scratches or anything to the disk read surface. The dvd is just dead. So what I want to do is to force mount the dvd and make an image and then try and sort through the files if at all possible. What I would like to do is:
sudo mount -t iso9660 /dev/sr0 /mnt/dvd -o force,ro
and possibly create an image or what I am most leaning towards is dumping the image to a file and then analyising it later:
dd if=/dev/sr0 of=/home/x/dvdrec.iso conv=noerror
but doing so gives me an error
dd: opening '/dev/sr0': No medium found
and of course the force mounting results in an error saying no media was detected...
Is there anyway to trick fstab into thinking there is a medium mounted there (like there is)
I have searched around the net trying to find some way to recover the files but have had no success. So I was wondering if what I said above would be possible and would work at recovering my files. Any other suggestions on recovering my data? Any feedback is greatly appreciated.

Nope no error with the drive (at least I dont think so), it reads other dvds perfectly fine, and before it read the dvds that I am trying to get it to read, I always run a data verification check after burning a disk and they always pass, then I try them just to double check.... I havent had a chance to try it on another dvd drive but I have arranged to use my friends computer to see if it works with his computer, if it does then the my drive is gone.... on the other hand if it doesnt work who knows. Another thing is that I have some other dvds from the same set that are perfectly fine, partly corrupt, and fully unreadable. I dont mistreat my dvds and I can see the burnt in data in the disk, but my comp just cant read it. Im at a loss. Possibly defective media? but that wouldnt explain why it worked before....

Mounting external hard drive at start up

Hello, I have a G5 and I recently purchased an ethernet external hard drive. I also have a PC and two powerbooks. Since I have so many computers and so many different users I want to be able to centralize my music collection and also all the files like pictures and movies. The problem is that the other users at my house hate mounting the external hard drive each time they turn their computer on, or bring it back from sleep mode. In windows I have the HD mapped and each time the computer starts the drive is mounted automatically. I would like to do the same thing on OS X. As soon as I start any of the mac computers and they finish booting up, I want to be able to see the external HD mounted without having to click any buttons or type in any passwords. Anybody knows how to do this? Thank you so much for your help
G5 Mac OS X (10.4.5)

sounds like you should set up a file server with OSX server software...

Can I mount external hard drive to Time Capsule and use it as external storage?

I have a 500GB external hard drive that I'd like to use on the Time Capsule as a hard drive to store mp3 and mp4 files. Can I attach it to the Time Capsule and use it like this? Or does it just give an additional 500GB worth of back ups from my iMac?

Can I attach it to the Time Capsule and use it like this?
Yes, if the drive has been formatted in Mac OS Extended (Journaled)...preferable....or FAT32. Access to the files will somewhat slower than if you had the drive attached directly to your computer.
Have you given some thought as to how you will keep this drive backed up?
Time Machine will not be able to back up the drive that is attached to the Time Capsule's USB port.
But, it would be able to back up the drive if you connected it directly to your Mac and the drive was formatted in Mac OS Extended (Journaled).

Does Final Cut Express 4 Read Clips From an External NAS Drive?

After upgrading from iMovie 08 to 09 I have found out through these pages that iMovie no longer supports reading clips from and writing them to my external wireless drive (via the Events library). The question for this forum - does Final Cut Express 4 have the same issue?
Just to anticipate a couple of points - I do not intend to use my external hard drive for 'in line' editing, it is merely a repository for excess clips that my hard drive cannot accommodate. I understand this kind of arrangement is slower than Firewire 800 but it is what I have and I want it to work.

FCE has nothing to do with how you archive your media as long as it's not used for playback within the application. The only issue might be how the drive is formatted. For large media files it really needs to be formatted in Mac OS Extended.
