My LaCie mini Hub External won't mount on my iMAC.

It has mounted many times just fine in the past until now. How do I force it to mount? I don't see it in the disk utility at all and the power light is showing on the LaCie. Do you have any idea why this is happening? Please help!

Hi
If the drive is powering on, then it is most likely not an issue with the USB port etc.
You may want to check in System Profiler under USB to see if the drive is there (Apple -> About this Mac -> More Info -> USB)
Also, try resetting the SMC & PRAM as that could help

Lacie mini HUB HD surge protector!??????

Hello,
I have a LaCie mini HUB external hard drive and it comes with it's own power supply but I was wondering if that serves as a protector from power surges. For instance if there was a power surge that blew out the power supply, would that also travel into the hard drive and destroy it?

Probably my ignorance rather than yours in that I might not have correctly described it!
A UPS is an 'Uninterruptible Power Supply' - it is like a power strip but with a battery inside, so when you plug devices into it, it can continue to power them for a few minutes even when the mains power is cut. That allows you to elegantly and safely power systems down rather than have sudden system failures which can cause serious problems to hardware - not least hard drives. The battery also allows for continued safe operation during brownouts where voltages can drop low enough to otherwise cause failures.
Some UPS devices (though not all) also contain surge protection, by which some or all of the power outlets on it are 'smoothed' removing voltage spikes from the supply.
Most users tend to buy surge protectors only, when in fact a UPS/surge protector combined is really a far better (safer) bet. APC (http://www.apc.com/) are one of the better and more common suppliers.

Need help with Lacie Big Extreme that won't mount

OK Guys,
My buddy's Lacie 1TB Big Extreme won't mount to any computer we try. The blue light is flashing. We have tried different cables on different computers. After a web search for similar problems we found out several people had success just plugging in a new power supply. So, we ordered one. Didn't work.
I can hear the drive spinning up. Oh, I guess I should mention this unit is out of warranty.
Here's my question. After some research, I found out this drive has 2 hard drives inside and set up as Raid 0. This is the way Lacie sets these up for use right out of the box. So if I take the Lacie enclosure apart and try to mount the drives separately in another generic enclosure what will I see in terms of the files written on a single drive (assuming it mounts) since I am dealing with an initial Raid 0 set-up? My intention is to save the files. Please help.

Same problem with an external LaCie Little Big Disk = does not mount, but shows up under FireWire in System Profiler. I assume it's a OS X issue, because I ran a software "Data Rescue II" and this software has recognized the disk.
Has probably something to do with one of the latest OS X updates, because I've used this disk with Time Machine now more than a year and never had a problem.
I recommend not to experiment with partitioning/reformatting (if you care about the data on the disk) and push Apple for a solution. It assume it's some kind of an access problem.

AirPort Disk doesn't work with LaCie Mini Hub & Hard Drive

I got my new La Cie Mini Hub and Hard Drive yesterday, backed up the PB and did a reinstall...no problems.
This morning, I hooked my LC into my AEBS went through the setup in AP Utility which saw the drive with no problems. But the AP Drive Utility doesn't see the drive. My AP firmware has been updated, and the software too. I even went through the setup in this posting:
http://discussions.apple.com/thread.jspa?messageID=4230118&#4230118
Any ideas that I may have missed?

I am dealing with the same issue, jeppeo. I have a 320 GB Seagate external HD (with both USB and Firewire). The Airport Disk Utility does not recognize the drive. It does, however, recognize my Kingston 1GB USB stick. Thus, I know the system works, it just doesn't seem to be working with the Seagate. It may be that the Seagate, and the LaCie you are using, are simply incompatible with the AEBSN. If that is the case, the only option might be to purchase a drive that is known to be compatible with the AEBSN, or any other drive and simply try plugging it in. I am considering buying a Western Digital drive (as many of their models seem to be compatible) and then testing it out. If it doesn't work, I will return it.

Office 2008 DVD won't mount on my iMac 2009, but other DVDs do

I was trying to mount Office 2008 on my late 2009 iMac 2009 so I could share the DVD and install on my new MacBook Pro, which doesn't have a DVD. But it kept on getting ejected. I tried other CDs and DVDs and they all seem to work in my iMac.
Fortunately it did mount on my old late 2006 MacBook Pro, so I was able to share that DVD and do the installation.
But... what might cause it not to mount on the iMac? The Office DVD is obviously ok. And the iMac DVD drive seems to otherwise work.
Any thoughts?
Thanks,
Doug

Haha. I'm not insulted. In fact I even thought of that and tried it.
The label side was facing me, so I was sure that it was the correct orientation. But just in case I did try reversing it, but it did pop out anyway.
Very strange.

One (NTFS) out of two partitions on a WD 1TB external won't mount after improper ejection

I've got a 1tb external WD My Passport hard drive that I have formatted into two partitions (One FAT32 that carries a bootable Windows 7 install for bootcamp and the like, one NTFS that holds all of my movies and TV shows). Originally, I set my MBP up to read/write to the NTFS partition via the method in this link: http://http://reviews.cnet.com/8301-13727_7-57588773-263/how-to-manually-enable- ntfs-read-and-write-in-os-x/. Everything was peachy; I could get onto that partition on my Bootcamped Windows and on OS X both.
So I took my trusty media library with me to Afghanistan. Seeing as I don't have a lot of options to back up all that data, whenever I wanted to watch something I would get my HD out of its safe place in my backpack, copy the file onto my MBP, replace my HD back in its sanctuary, and watch straight off of my computer.
This time, though, since I was only watching one 20-minute episode of Batman Beyond before I got in the shower while I drank my post-workout shake, I didn't bother with my safe method. SURE ENOUGH, in the middle of the episode, I knock my HD straight off of my bunk, it falls off of the cable, and lands on the floor.
My first thought was that I might have broken an armature or dislodged the spindle/platter assembly. However, the drive spins up fine, doesn't make any noise, and the vibration in it feels normal. Also, I can still see the my FAT32 partition like so: http://i.imgur.com/S0rF0wK.jpg
I can also see my old partition in Disk Utility, but can't manually mount it: http://i.imgur.com/A44Ld4P.jpg (indeed, my name is Forrest)
Nor can I mount it manually through Terminal diskutil commands, but I think I may not be doing this right: http://i.imgur.com/fx3H9QH.jpg
I realize that I may have corrupted something and that my last option might be to erase/reformat, but I would REALLY prefer not to go down that road right now; I barely have Internet much less the ability to repopulate a media library.
I tried:
-restarting my computer (of course)
-dismounting/remounting HD
-sighing heavily
-viewing the HD from Windows (which sees the FAT32, and sees a drive letter for the NTFS but won't read it, just hangs when I try to access it)
-using chkdsk from Windows (get error that I need to be running in an "elevated mode" for that operation, which is something else I'll be addressing soon)
-cursing
-mounting manually with Terminal commands (see above)
-coming here to beg the gods' forgiveness and hopefully get advice
Tell me how to fix this and keep all of my movies and TV shows and I will owe you one (1) undying gratitude.

Hi Kool G4. I think that I'll take a trip to Tek Serve tomorrow and see what they can do. I was hoping for the same luck I had with the internal one re-appearing, but so far nothing.
I guess that every once in a while when something is improperly ejected, the warning is valid. There have been so many improper ejections (not on this drive) that have not resulted in a failed drive. My luck, and on my very important drive. Bummer.
But thanks to all of you for offering your wisdom.
I'm going to leave it overnight plugged in just in case it's just a slow startup issue. *crossing fingers*
Otherwise, I do hope that a specialist can recover the data.

LaCie USB 160GB HDD won't mount, just beeps

Purchased a new 160gb LaCie external USB HDD, but can't get the mac to recognise it. I have tried it with and without the additional USB power lead, but nothing happens. The HDD just constantly beeps.
Not sure what to do. We have tested it on other macs (laptops & desktops) and it mounts straight away no problems. The USB ports work for other things fine.
Any suggestions would be appreciated.
Thanks

Welcome to the Apple discussions.
Powerbooks often don't put out enough juice on the USB port to power external hard drives. The external drive may not start up or may start but still not be recognized by the system. One solution is to get a power adapter, as Hardy recommended, or, if possible, to use a Firewire connection (Firewire doesn't have the power issue USB has). There's also an advantage to using a Firewire connection, in that Powerbooks can only boot from a Firewire device. So, a USB only hard drive, once it starts up, is fine for backup but cannot be used to boot the system, if needed. Lacie sells a power adapter for around AU$25.

10.6.3 disk won't mount on intel iMac

I have an intel 3.06 GHZ Core 2 Duo iMac running 10.5.8. I purchased Snow Leopard family pack 10.6.3. I installed the disk but after about a minute it dismounts and gets ejected. Won't display on desktop. What's up?

Or the disc itself could be damaged, possibly as a result of use in some other Mac with a dirty optical drive or contamination or scratches from handling it between uses. Look carefully at the surface of the disc for scratches or contaminants, which may be faint & hard to see.

LaCie external drive won't mount on iMAC

Hi,
My external LaCie external drive won't mount on my iMAC running 10.6.8 but will mount and show up on my PC as working fine, however I am not able to read the information on it as it was formatted for my iMAC. Therefore it leads me to believe this is a software issue.
I have reason to believe someone had changed the permissions and prevented the mounting of this external drive (which belongs to me) so that the contents won't be found on my iMAC.
How to resolve this issue?
Thanks in advance,
Cait

Cait,
Please try a SMC reset, it may take 2-3 attempts for it to work. Look over the instructions below carefully.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Forgot to eject LaCie HD - won't mount now - can it be fixed?

Through my own stupidity, I forgot to eject my LaCie external HD before I powered off the LaCie (it was late and I was tired). Now it won't mount on my iMac G5. I tried to repair it using Tiger's disk utility but to no avail. I just get an "exit error" message. Does anyone know if repairing the LaCie thru Tiger's disk utility would fix it? I'm afraid to try. Or is the LaCie now a lost cause?
Thanks for any advice.

Hi Eugene,
Did the same a while ago. My LaCie was dead.
Using Data Rescue X (from Prosoft I believe) was quite helpfull. You can retrieve data from your 'dead' LaCie and fix the drive once your valuable data is rescued...

Perhaps the 'testdrive' is all you need...
Good luck!

External drives won't mount after running repair permissions

None of my external drives will mount after running disk permissions. Drives work fine on my mbpro.
None of the external drives show up in disk utilities...
I've try shutting down and unplugging computer. even mini zip drives won't mount.
I'm running 10.4.11
PPC G5 2.3Ghz
Thanks for any help..

Repairing Permission only deals with installer receipts and system components. Not with mounting or accessing hard drives.
Have your run Apple DU First Aid? Disk Warrior? Only use latest version for your OS.
Are you trying to clone your system to external and then repairing permissions? trying to boot from them?
If cloning, make sure the "Ignore Ownership" flag is unchecked before cloning (but do repair permissions on external drives you intend to boot from, such as a Firewire drive).
What type of cases and interface are these?

Time Capsule won't mount after upgrade to iTunes 9

See my full post in the Time Capsule support section ("Help! Time Capsule won't mount after installing iTunes 9"). My music library is on my Time Capsule, but after installing iTunes 9, it won't mount on my iMac G5. I can use the internet, but the disk won't mount. My Powerbook hasn't been updated yet and the Time Capsule mounts fine.

To make it easier, here's the post:
"My music library is on my 500 Gb Time Capsule. I just installed iTunes 9 on my iMac. It updated my library and synced my iPhone. Now, the TC won't mount. I still have internet connectivity, but I can't access my media or print to my printer connected to the TC. I can use the computer and everything, but if I hover my mouse over the TC disks menu bar icon, I get the spinning beach ball there. If I try to connect using my Network icon in the sidebar, it allows me to log in and get to the screen to select the volume I want to mount, then stops responding. In the Activity Monitor, AFP Client & AirPort Base Station Agent are not responding. I also have a Powerbook G4 w/Leopard (10.5.8) which hasn't been updated to iTunes 9 yet. The Time Capsule mounted fine on it."

Burned archive CDs won't mount on OS 10.7.5

I have been archiving photos onto CDs for a few years, and most of them are fine. But there are 3 that won't mount (on 2009 iMac or 2007 MacBook both running OS 10.7.5), two from 2003 and one from 2005 (others from 2005 are fine). Does anyone have ideas about how to fix this? I've been googling for solutions without success.
Many thanks!

Additionally, if you must have them on CD or DVD, the only thing I would suggest is the rather expensive archive media:
http://www.verbatim.com/subcat/optical-media/dvd/archival-grade-gold-dvd-r/
I have burned some very important data as well as some one-of-a-kind foreign language movies to those DVDs. They as supposed to last 50 years or so.

Smartdisk Firelite Won't Mount

My 40GB Smartdisk Firelite won't mount on my iMac. It did at first but now it will not. I see the Smartdisk in the system profiler.
I am using the ac adaptor in case the USB port cannot supply enough power.
Any suggestions?

Well I called Apple support because I also tried a thumb drive and had the same problem!
Apple had me shut down my computer, wait 1 minute, unplug the USB cable and then restart the computer. After the computer restarts, plug the cable back in and sure enough the drive mounted.
Well, I ejected the drive and unplugged the cable and tried mounting it again and it worked. THEN the next day I tried again and it wouldn't mount so I did the whole shut down process again. Never mounted!
I do not have this problem with printers, scanners, cameras only storage devices.
So, then I tried the USB port on another computer and sharing the drive as a network device and I can see it just fine.
I also tried a new Airport Extreme Basestation and I could connect to the drive but when I opened it and went to add a new folder, everything disappeared. After panicking for a few seconds, I unplugged it and took it to a PC and everything was there, including the new folder I created.
So for now I guess I will just leave it connected to the PC and access via the network.
That is a poor solution though. I should be able to connect directly to the iMacs USB.

My dumb external LaCie won't mount.....AAARRRGGHH!!!

I'm really hoping someone can help me here. I was working on some illustrations and in Manga studio debut, i opened a window to post some work i created into my external harddrive. I mistakenly hit the "eject" symbol that unmounted my hard-drive from my computer. So i said to myself,"No biggie... i'll just shut the drive off, unplug it, wait awhile, replug it, shut it on and it'll mount again.
nope.
I shut it off, unplug it, restart the computer. plug it and turn the external harddrive power on... nothing. i wait patiently thinking it'll eventually kick in.
no kicking.
i'm a 40 year old man i'm contemplating crying now... because more than 200 gigs of important work is on my drive and i can't access it.
That and stupid Leopard can't even do the most basic commands.. like accessing my printer. Just get that dumb beachball. Even opening System preferences gives me problems. More beachball.
I'm looking for help here. Please help.
How can i shed my computer of the recent upgrade and go back to 10.5.2?
and Since nothing can be wrong with my LaCie by just unmounting it, what can i do to get it to mount? Just leave it plugged on and powered and pray that the OS recognizes it and hope it mounts?
I don't have that kind of time.
If i need to retrieve all that data onto another new external, how much will that cost me?
I know i'm asking a lot of questions, but i'm desperate here.

The problem is that it won't mount after it has been unmounted. A friend of mine who's a Mac Repairman told me that it could be a number of things...
he told me to check if any smells were coming from the drive...
nope. check.
If the fan had stopped working... nope. check.
If it's a problem being caused by the enclosure.... that i'm going to check on.
I called TekServe in Manhattan and when i get paid, i'm going to see if that's the case.
But they want 1200.00 for data retrieval in a worse case scenario... and i'm going to shop around for that one. I have a feeling that they corner the market in that area for Mac repair and they probably feel they can charge whatever they want and people will pay.
1200.00 is another computer. I'd rather do my research before shelling out that kind of dough.
I had unwittingly unmounted my first external 3 years ago .... it's a Wacom, and it mounted with no problem after literally a minute.
So i don't know why this LaCie is giving me problems.
So i'll try changing enclosures and check out reports for the companies with the best all-around reports on their externals before i buy.
It may not last forever, but i should get better than an external HD's "refusal" to mount once unmounted.
It just doesn't make sense.
Besides, i have a feeling that my computer won't register it's existence if it doesn't mount to make itself known.
Tell me if i'm off.
BUt i will consider the other programs that you guys have suggested.
