Mac no longer 'recongises' my lacie external drive

Please please can someone help me. I have a 2.4 intel core 2 running 10.6.8  I have connected to and used a lacie external fdrive for a couple of years and now suddenly my mac does not recognise it - it doesnt show in finder. I've done all the usual things like unplugging everything, shut down and restarted but it still does not show up. My system has 500gb but is at max so I need topush some files onto the lacie.
I am at a loss.. please, does anyone know what I can do to fix it ?
Many thanks

You can also do some basic trouble shooting including switching cables, turning off the power on the EHD, then restarting your computer at the same time doing a SMC reset and then reconnect the EHD. If that doesn't work connect the EHD to another computer to see if it's the EHD or the computer.
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.

  • I'm using Time Machine and a LaCie external drive to backup. I also have a 8 GB LaCie flash drive I want to use for small jobs. If I plug the LaCie flash drive in, is my Mac going to think it is the LaCie external drive and start trying to backup?

    I was finally able to resolve this issue. I went to LaCie's site and went to the support area to find troubleshooting steps for my particular drive. It turns out that the problem was corrected when I swapped the power supply cord of the "troubled" drive with another LaCie drive that I have and that seemed to resolve the problem. Thank you Tony for your help. I appreciate you guys!
    Thanks,

  • How do I format a new lacie external drive to work on a mac and pc?

    i have a new lacie external drive. I want to partition it into 2 parts, one to use in Macs and the other in PCs.
    How do I do this in Disk Utility?
    thanks!

    Click on the entire drive in the Disk Utility's sidebar, then on the Partition tab, and set it up. Format one partition as Mac OS Extended (Journaled) and the other as MS-DOS.

  • I tried installing a lacie external drive and now i cannot log onto my mac pro

    i recently purchased a Lacie external drive, tried to install the setup but got an error message now unable to log on to my mac pro

    MacBook Pro or Mac Pro?   Mac Pro is a desktop machine, MacBook Pro is a notebook.
    Is there an operating system on the LaCie?
    And whose setup did you try to install?
    Do you have Boot Camp installed?

  • Kernel panics on LaCie external drive with Mac Mini

    Hi there.
    I recently purchased a LaCie external drive to use with my Mini. My intent was to boot from the LaCie drive and use the Mini for backup. Everything was working well until I upgraded the LaCie drive to 10.4.6. I started to get a kernel panic once a day. I reinstalled the OS (I have disks up to the 10.4) but held off doing software upgrades so I could try to isolate the cause of the kernel panic. I couldn't. I currently get the panic notice every few minutes, regardless of the version.
    I am planning on taking both drives to the Mac store on Monday, but am wondering what my options are. Is it okay to use the LaCie drive as my start-up or should I get a bigger drive installed in the Mini and use the Mini as my start-up instead?
    Is there any chance I can solve this kernel panic problem on my own? Reinstalling, running disk utilities, etc hasn't helped.
    Thanks for any insight you can provide.

    Mac Mini   Mac OS X (10.4.6)   40 gig Mini plus 250 gig LaCie external

    ok first off how big of external drive
    the reason i ask is this
    on some external inclosures designed for the mac mini exceed 120 gig to 220 gigs you will have some major issues one is kernal panic one is the mac os x desktop becomes unstable and certain applications will crash like utilitys and even system preferences
    and your dvd software will also have trouble playing dvds
    i ran into this on a g3 tower and the same thing happens on certain models of laptops but i have never heard of this happening on a mac mini this is a first

  • Fix for Mavericks compatibility with Lacie external drives yet?

    My last attempt to upgrade to Mavericks caused my 2 Lacie external drives to become unrecognisable to my mac. Update hung up too so I lost everything...luckily I had a third back up with CCC that saved me. Im just wondering if there is a fix for this now. I got no information or help from Lacie.

    Exactly the same here. Installed Mavericks and La Cie no longer shows in Finder and Time Machine reminds me that no back up has taken place. As an iMac newbie where do I go from here. In my Win PC days I always backed up to an external HD on a scheduled basis without this sort of problem.

  • HT3275 Lacie external drive/Time Machine errors

    I am using Lacie external drive with Time Machine and now have an "invalid node structure." Wants me to back up and restore...again. I have had problems in the past and have restored twice so far.  Other problems include "Incorrect number of thread records" and "Invalid directory item count." Why does this keep happening? Is it normal to keep restoring your external hard drive? Where else should I back up my hard drive?

    I wonder if this is a problem with Time Machine or my external hard drive.
    Hard to tell, unfortunately.  As posted earlier, that can be caused by lots of things.
    Our Lacie hard drive is backing up everything that is on our computer. Meaning there isn't anything getting backed up that has been deleted. But it is annoying to erase the darn thing every couple of weeks and load it all on again.
    My advice would be to get another drive.  Since you have a desktop Mac, get a desktop drive, with it's own power supply.  Plug it (and your Mac) into a same good-quality surge suppressor;  or, better, U.P.S. (battery backup) system. 
    It's always prudent to keep secondary backups.  See Time Machine - Frequently Asked Question #27 for an explanation and some suggestions. 
    That recommends using a different app, but in your situation, you might want to use both drives with Time Machine temporarily; you'll have to switch back and forth manually via the TM Preferences panel (Mountain Lion allows multiple destinations, but Snow Leopard doesn't).  If the new drive works fine, but the old one doesn't, that will implicate the LaCie, or it's connections, etc. 
    If you determine it's ok, then use one (probably the desktop) with Time Machine, and the Rugged with another app.  Consider taking it off-site, as mentioned in #27.
    If it's not ok, replace it.
    I am running 10.6.8 and have Lacie 1T Rugged external hard drive connected by firewire on my Mac desktop.
    I have a smaller version of that drive, as do several folks here.  It gets good reviews, but like any drive, won't last forever.  If it's over about 3 years old, it could be starting to develop a problem.

  • G4 Won't recognize Lacie external drive

    My G4 will not display/boot my Lacie external drive. I've used it for several years, so it has worked in the past. We had a power outage and after that it won't regonize the drive. I tested the drive on my Mac laptop and the drive works fine, just not on my G4. It powers up when I plug it into a G4 firewire port, but won't dsiplay/mount on the desktop. I tried rebooting everything and unplugging all other USB and Firewires from the back. No use. Any suggestions? Thanks.

    Hello! Try hooking it up to the book and repairing the drive in disk utility. Then dismount it and unhook it and turn off it's power. Then reconnect it to the G4 and then power it on. Sometimes this will get it to mount. There have been some LaCie's that have had problems with a weak power supply. Tom

  • HT201250 Can I use Time Machine on two different Macs to back up to one external drive?

    Can I use Time Machine on two different Macs to back up to one external drive?
    I have one 1T Western Digital backup drive that works well with Time Machine and my MacBook Pro.  I now want to back up my wife's MacBook Air using Time Machine on her Mac and want to know if I can use the same WD external drive or if I need to get a 2nd back up drive?  If I can use one external drive for the two Macs do I need to do something special on the drive or will Time Machine do it automatically?

    Yes. You will need to configure Time Machine preferences on each computer to backup to the same drive. Note that you cannot connect the backup drive to both machines at the same time.

  • I have an issue with time machine, it doesn't find the Lacie external driver it use to use. it is the same drive that I usaly use for time machine back ups. It is corectly plugged. What can I do ?

    Hi,
    I'm trying to back up my macbook with time machine on the Lacie external driver I usualy use for this, but today my computer doesn't find the driver. I haven't done back up in 6 month.
    Today, the Lacie driver is pluged and running, but the computer just does'nt find it.
    what shall I do ?

    Some things to consider:
    Is the drive mounted, i.e., visible via Finder and/or on the Desktop?
    Is the drive still selected in System Preferences, Time Machine? If not, use the "Select Disk" button.
    Is Time Machine still turned on (System Preferences, Time Machine)?
    Can you see the drive (and mount it) using Disk Utility (in your Utilities folder)?
