Lacie 500GB Porsche USB 2.0 external hard drive will not sleep

Hi there,
I bought a Lacie 500GB Porsche USB 2.0 external hard drive that shipped along with my new iMac. I have noticed that even though I check to "put hard drives to sleep" when not in use under system preferences, this hard drive will never sleep. I have to eject it and then turn the hard drive off. Anyone know how to fix it or know if it is a Leopard or Lacie issue that might be fixed with a driver or firmware update?

Hi,
I just got the same drive and was wondering the same thing. I inquired with LaCie about it and here is the response that the support people gave me:
"That particular unit does not sleep. We changed the bridge to the newer controller, which is faster and better for data transfer, but that feature was dropped from the design. I'm sorry."
Hope this helps.

USB 2.0 External Hard Drive Will Not Mount (Mac Mini Duo)

I have recently purchased a refurbished USB 2.0 500 GB Lacie Big Disk d2 Hard Drive. It is supposed to be plug & play but I cannot get it to mount. I have tried Disk Utility but nothing. Any help will be greatly appreciaited. Thanks

System Profiler recognizes that it is connected but
nothing in the finder or disk utitlity.
What does it show up as in System Profiler?
Sounds like the USB interface is munged. When attaching the drive, always do it in this order:
1. Turn on the drive
2. Attach the USB cable to the drive
3. Attach the USB cable to the computer
You might need to reboot to clear the USB bus. Then attach the drive again in that order. Actually, once it's attached, a reboot should also work. Try that first, if you're already attached, Then try a reboot attaching the drive in the proper order.
In the olden days, we used to recommend zapping the PRAM. Does that still apply these days?

My WD 2tb external hard drive will not unmount from my MacBook Pro.

My WD 2tb external hard drive will not unmount from my MacBook Pro. It no longer even shows up in finder, however it does show up in Disk Utility. I have tired so many of the suggestions on the internet all to a fail.
I keep getting the message to be sure that all applications are closed before ejecting the drive. I have no clue how to tell which appliactions are using the external drive to shut them off. I turned off Time Machiene to be safe.
I don't need anything on the external drive, I am just trying to erase it, save my current info, and migrate it to my new MacBook Pro.
I have been about four days now with this issue all over the internet, in this community, and watching videos on everything and nothing about this topic to a fail.
I think I am doomed and have lossed this external drive because of some wierd application that will NEVER close on my hard drive for it to disconnect correctly. It's annoying.
Does anyone have a solution?

Have you trie using another USB port? Can you test the USB ports with other USB devices to assure they are working? You may want to reinstall OS X in case there has been a driver glitch.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
It is an indication of serious Directory damage.
that leaves
a) third-party Utilities that will take those risks, or
b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

I recently updated my Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

I recently updated my 20-inch, Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

Can you see them in Disk Utility?
If so, can you select and Mount them?
If not, disconnect them, reset the iMac's SMC and then reconnect them.
Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If you still can not see them, connect them back up to the iMac running the older OS, open Disk Utility and look to see how they are partitioned and formatted.

External Hard Drive will not mount after upgrading to Yosemite

After upgrading to Yosemite, my external 3TB hard drive will not mount... can't see in Finder, but does appear in Disk Utility. Follow steps to Repair disk, but get a message that D.U. cannot repair disk.

See mount section.

External hard drive will not eject

Since upgrading to ML my small "my passport" hard drive will not eject. First it gives me the message "the disk couldnt be ejected because Safari is using it and to close Safari and try again". (not sure why safari would be using it..) When I close safari then I get the message " the disk couldnt be eject because another program is using it"
My only option is to force eject each time.
Any suggestions?
Thanks

My Lacie external hard drive will not back up on Time Machine. Says there's not enough space. This has happened with every single external I've purchased. Thought TM was supposed to delete old backups??

My Lacie External backed up on Time Machine after the first back up but now says there's not enough room. I thought TM deleted old back ups to save new versions. What am I doing wrong. This happens to me constantly. Every single external hard drive I've purchased for the MacBook Pro (5 of them) has not worked either initially or at the second back up. It either isn't formatted properly so I have to go to Genius bar to help me set up for the first back up, or after the first back up, it says there's not enough space and I have to go back to Genius Bar. Is there a way I can fix this on my own?

I just purchased 2 external hardrives. a LaCie Minimus and a G Drive. Each 1 TB. The guy at Apple told me that would provide 2 good TM backups for me. My internal HD has 750 GB capacity, of which I'm using 700 GB. Perhaps the ratio is not great enough. I do wish they would have told me this before I purchased the two Bummmmer! I even had them format and get the first back-ups going because of issues I've had in the past. I also just bought a 750 GB for photos.
So, I won't be able to buy another bigger external since I've just purchased 3. Ugh. Well, I'll just exclude some files and divide things up. Eventually, I just want my 20,000 iphotos on one of the 1TB externals, and a TM back-up on another so that iphoto will function once more. It really hates how many photos I have and is brutally punishing me for it.I seriously need to do some housecleaning!
Thanks for the advice. Just moved from US to Australia last week and was hoping to upload a few photos and the domino effect has lead me to this. Just went to Genius Bar in Perth today and they told me how to reformat drive to transfer iphoto library over, but I got stuck at trying to back-up my TM.

LACIE external hard drive will not mount

I had this problem with Tiger too. I have to turn the LaCie external hard drive on and off 4 or 5 times before it appears on my desktop. This shouldn't be right! Can I do something about this???

Another Lacie issue (lacie 250 d2) . Similar the others. WHen I installed leopard it asked if this was the drive to use etc and i said yes. Since then it wont work. All attempts to back up have failed. I cant reformat either. Just get beachball when ever I try anything with the disk. Only way to do anything is to remove the FW connection. Tried the drive on another G4 (tiger) and it scanned and reported "disk seems ok" but then any attempt to write to the drive or any other activity is greeted with beachball.'
Rang the distributor and was told " we are having some issues with lacie and we are losing confidence ... would you like to buy a western digital" !!!

External Hard Drive will not mount

My external hard drive that I been storing all my aperture files on is not mounting to the desktop. I can see the hard drive when I use my disk utility, but it doesn’t show up in the desktop.
When I purchased the hard drive originally I didn’t format to apple but it worked fine.
Please help…

Make sure the drive is powered from from its separate power source, not solely through the FW or USB connection.
If it is a dual connectivity drive, try connecting from the second method (e.g. if you are using the much preferable FW, try switching to the much-less-good USB).
Repair Permissions, even though that is fairly unlikely to have any impact.

I have a WD & LaCie external hard drives in my iMac G5 they have been working fine until I started using the new Time Machine program. Now the drive show up in disk utility but not on the desktop. Disk utility has been no help in repairing them and in its log states " Invalid content in Journal " .
How do I get my drives back ?

I did an archive reinstall of Leopard and I still had my problem, so I schleped it down to the Apple store and for the life of me We could not make it happen, drives shoed up fine and worked fine. I think I have a bad FW port that is intermittant but for now I cannot have them fix something that seems to work...
I dont thisnk we have the same problem, because when I had my drives not showing up on the desktop, they were not showing up in Disk Utilitiy either.
Is there data on those drives that you must have? If not I would try reformatting them with Disk Utility ("erase") and see if they reappear. If there is data on them, I would try running a better utility program such as DiskWarrior, I think you can run it on external Disks to rebuild the directory. The problem is that the present version, 4.0 is not compatible with Leopard. The new one is out soon if not already for Leopard. There is no guarantee that that will work, but may be worth a try.

Toshiba ph3100u-1exb External Hard Drive Will Not Stay On

Hello all.
I recently purchased a Toshiba ph3100u-1exb 1.0 TB external hard drive. It's working great, but the problem I am running into is that it will not stay powered on for more than a couple minutes. I'm sure that its some kind of power saving feature, but if there's a way to turn it off, I'd like to have the drive accessible at all times, as I use the information stored on it quite a bit.
When it powers down, I can always press the power button to bring it back up, but I would like to have it on all the time. Is there any way at all to do this? A setting on the drive, or possibly within Windows?
I have the drive hooked up via a USB cable, as this PC is a bit older and does not use the eSATA cables for hard drives.

Hi
In my opinion the HDD should be checked with different computers and different OS (Vista, Win 7, Win XP). If the external HDD will not functions using different systems and computers then its definitely an HDD issue.
Ive got 2 different external HDDs one HDD died and I had to replace it.
In my opinion, if an HDD begins to malfunction then its mostly an hardware related issue and there is nothing to do as to replace the faulty drive

External hard drive will not mount nor repair... ='(

My internal hard drive was failing, so I backed up all of my data onto a 500GB WD Passport external hard drive and ordered a warranty replacement. Yesterday I received the replacement and went to restore my data. I used Carbon Copy Cloner to restore it and after about 45GB, my computer completely froze. I restarted and tried again, this time the same thing happened at the same point. I restarted, but this time it would not boot off of the external HD. I booted off of another external HD and ran "Repair Disk" in Disk Utility. It took forever, but when it finished it said something like I need to backup, erase, and restore. The problem is that I can't access any of my data on the drive!
Is there any program I can use to repair it? Or is there any way to force it to mount?

I won't try to answer any of your questions, but I do have a set of my own: How did you initialize that replacement drive? Did you set the partition map scheme to "GUID Partition Table"? Did you format the volume as "Mac OS Extended (Journaled)"?

External hard drive will not format

I have a 500gb mybook external hard drive and for the first year that i have had it there have bee no problems. but after doing a software update and restarting my computer i was greeted with a message giving me the options to ignore or initialize. i couldn't find my hard drive on my desktop or in finder so i went to disk utility only to see that my drive was now listed as wd 2tb. i tried to format but it just says input output error and i cannot verify or repair permissions because all of the buttons on the first tab are grayed out. Any help would be greatly appreciated.
thanks

Sounds like the drive may have failed. You can try the following, but if you have no success contact WD support.
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu one. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

External hard Drive will not mount via firewire tpo my Powerbook G4

I have a Powerbook G4 1.5, 2 Gb Ram and an 80 Gb Hard Drive. Well my problem is, I went and purchased a Western Digital External Hard Drive. The box states that this hard drive is compatible for both Windows and Mac. But for some reason I can't get the external hard drive to mount via the firewire. However it will mount by using the USB.
So can someone please provide some troubleshooting tips on how I can get this external hard drive to mount?
Thanks

hi there,
in your case, your drive is probably bad because the copy was interrupted. your hard drive may be finished, but more likely, just the file structure is damaged and/or you have bad sectors.
you have a few options:
*if you don't need the data back:*
• see if the drive appears in disk utility and try to erase/reformat (make sure to zero out data to avoid bad sectors)
• if it doesn't appear, try a pc. it won't recognize it, but it may allow you to reformat/initialize it. then, connect back into mac (which will recognize a pc formatted drive) and reformat as mac os x extended (journaled).
*if you need the data back:*
• try a program like data rescue II, file salvage, or boomerang data recovery first to recover the data
• see if the drive appears in disk utility and try to repair disk
• if that doesn't work, try disk warrior and/or drive genius
• if you aren't successful, you may want to try a professional data recovery service (or me first, to ensure that you actually need someone as high tech as drive savers)
• if you are successful and are able to recover the data, then erase the drive (zero out data) and then move the data back, to ensure you're working off a well formatted drive.
fyi, if your computer freezes in the future, be sure to try appleoptionesc first and force quitting the problem application. if that doesn't work, try controloption+appleeject (shutdown) and/or optionappleeject (restart). if those doesn't work, in this situation, the next best move would probably have been turning off the power on the hard drive. if that doesn't unfreeze the system in a few minutes, then hold the power button.
hope this helps,
