My lacie Big disk 500GB drive will not mount even though it shows in Disk utility (unmounted) and in System profiler. When I run Verify Disk in Disk utility it says: ERROR: The underlying task reported failure on exit. Any suggestions? Cheers Charlie

    Thank you, I think I will attempt to save the data somehow as cheaply as I can and then see if I can get it fixed.

    Cheers for all your help

Try rebooting and hold down the option key, you should then be able to select the Mac partition.

    If not, then put your Tiger DVD install disk in, and reboot holding
    down the c key, do not do the install ! but run Disk Utility from the
    Menu bar...run Disk Repair.

    If you try to repair a disk that cannot be unmounted, the repair will appear to start, but then stop as Disk Utility displays this message: "Repairing disk failed with error. Could not unmount disk."

    If you look in the Console (/Applications/Utilities/), you will see an entry like this:

    Verify and Repair disk “Storage”

    The disk “Storage” could not be unmounted

    Could not unmount disk for verification

    Repairing disk failed with error. Could not unmount disk
    In some rare situations, your computer might not respond for several seconds.

    If you cannot determine which files are open on the disk that you
    want to verify or repair, restart your computer and then mount the disk
    again, or start up from your Mac OS X Install DVD or CD to repair.

Try first unplugging power, if it does not work try uninstalling and reinstalling disk utility

    Try first unplugging power from computer and Lacie disk for ten minutes, if the computer is a laptop or a Mac notebook, then also remove the battery at same times.

    If it does not work then try uninstalling and reinstalling disk utilit, Check if your lacie is displayed as external disk in your computer resources. If you are using Windows XP, for example, check if you have a new external disk in My Computer, in this case the problem is only with Lacie software, as the computer is seeing the disk.

    If the disk is accessed through a network also disable all firewall software to test the disk.

    If you have a different computer test also the Lacie on the other computer, to see if the external hard drive is faulty.

    Hi, when Lacie does a kind of tickling noise and it does not start, that means the disk is faulty. Testing it on a different computers also confirmed the diagnosys.
    When this happens you can fix it only by replacing the internal hard drive, all data inside are usually lost or recovered at an high price from specialised data recovery companies.
    The disk can be fixed for a not too high fee at any computer shop.
    If you just bought the disk take it back to seller.
    If disk is less then one year old contact Lacie to check if you can validate your guaranty, you find number on booklet that came with hard drive, or on Lacie website here.:

I bought today a lacie hard disk 500GB and instead of 500GB has only 9.99 MB space.What's the problem?


Sounds like your have a 9.99mb partition on your drive with the rest being free space.

If you are running windows goto the Computer Management program and check under storage> disk management to see if your 500gb drive is there. if it is delete the existing partitions and reformat the entire disk to NTFS

I have a 1TB LaCie 2Big Quadra. It has 2 500GB and runs on RAID 1. I replaced both 500 GB LaCie drives with 1.5 TB LaCie drives, but my computer only recognizes the original 500 GB. I formatted both...


I have the same problem too on my 2big form lacie . If I use 2x 1,5 tera disk in "fast mode" or in "big mode" my disk manager only shows 746 gigs available (it should be at least 2,5 terra).
If I use "safe mode" so my system can see 1,3 tera available, wich is normal for a raid mirror configuration.
I hope to find a solution quickly.

My lacie mounts on the g5 but when i click it, it doesn't open.


It would be a good idea to look at the Mac system log so from a v bad memory do...click Apple (top laft hand corner) then about this Mac then System Profiler then Logs and take a look and see what errors you are getting. If this doesnt give you any clues my advice with external disk problems is where possible to remove the disk from the enclosure and install it in the Mac. if you can, THis will eliminate the USB cable, interface, and box. See if it mounts then. If it does run disk utility to double check it but get your data off first onto the Mac. Hope this helps....Mark

Trouble seeing my lacie drive possible mounting issue


Hello,

It sounds like the RAID controller in the LAcie drive may have failed. When this happens generally the data on the drive is left intact but you will require a new casing for the drives and the help of a data recovery pro to get the files off before you can re-initialize the set. Unfortunately all the good free/cheap utilities work only on single drives so you will need the help of a pro with high level software and additional equipment to retrieve the files.

If you are in North America I would recommend Armor-IT Data Recovery, they're listed in the FixYa service database for most US states. If you're outside North America, post your location and I will help you find an appropriate service.

Freezes up During Backups


I suggest an application called "Disk Warrior" it has always maintained high ratings among us Mac enthusiasts it has a hardware test function built into it and seems to be a little better at verify and repair functions than Disk Utilities which you can try also if you haven't yet. You may also consider trying a different firewire cable if you have one handy. Other than that a reformat should have put the disk back into an original state however the disk could have been damaged by not un-mounting it in rare mac cases. If you have the time you can also reformat the disk again although I would try the first two options first.

LaCie 500GB external will not show up on mac desktop. Blue light on, whirrs as if working but no icon on desktop (not mounted)


Did you format the drive using Disk Utility? Open "disk utility" from the dock icon or applications/utilities folder. Click the drive name on the left side of the disk utility window. click the "partition" tab in the window, next click the "options" tab and select GUID Partition scheme, or any Mac compatible scheme, read each explanation of the schemes. Name and resize your partitions, click apply. This is how it works running Leopard, not positive if the same applies to Tiger. I hope this helps you

Trouble seeing my lacie drive possible mounting issue


Not sure if this is the exact same issue, but I couldn't get the drive to mount with different connections, etc. The problem turned out to be the power adapter. If you've got the same kind of adapter on another drive, switch it out and see if your drive shows up. Good luck.
