LaCie external HD does not mount after lion 10.7.2 upgrade

After the upgrade to Lion 10.7.2, my external LaCie 2big Quadra (connected through FW 800 to a MacMini late 2009) was no more visible to the system.
This has not been the first issue with this disk since I have Lion: after the upgrade fron Snow Leopard to Lion, the "Ignore ownership" flag of the volume was resetted to "marked" (which was a mess because I had my whole home folder on it).
After the 10.7.2 upgrade, I had no chances to re-mount the volume with Disk Utility (dimmed button) but, using the terminal I was able to find it in the /Volumes mountpoint and to recover my home with the ditto command to the MacMini internal drive.
After this I reformatted the disk and now it seems to beave properly but I have seen on the web plenty of troubles regarding FW management under Lion and I am not sure if it is a good idea to trust it again.
Does anybody have suggestion or news?

My Lacie ethernet mini is not working after Lion upgrade.
Finally got an admission from Lacie that the login software won't work with 10.7 and they suggested going back to Snow Leopard . . .
Apparently the login software cannot be changed or overwritten so now Lacie drives are obsolete when using Lion.
I wish there was a way to wipe it clean and use it without the login software, but they couldn't suggest a way.
I note you may have had better luck but I don't know how to use terminal, so I may have to junk it, or possibly take out the drive and buy a caddy for it?

My external HD does not mount despite it appears on Disk Utility

I have been using an external HD to keep my video library. Just this week I updated my library and everything was OK, but when I tried to see the videos on my mediaplayer the disk didn't appear. I connected it again to my iMac but now the external HD does not mount. I tried Disk Utility, the disk appear gray on the sidebar but it doesn't mount. I run Repair but I get the b-tree node size error and the disk still does not mount.
Please help!!!!

If DiskWarrior can't fix it, you might try Data Rescue II...

USB Flash Disk does not mount after Leopard Upgrade

I am not able to use my USB flash disk after the upgrade to Leopard. The disk does not mount at all, though i can see it listed in the System Profiler.
Before the upgrade to Leopard, the same disk used to work perfectly.
Can anyone please tell me how I can solve this issue ?
Thanks.

Check to see if your USB Drive has the latest firmware. Leopard tends not to support older firmware.

External Drive does not mount with Firewire but is ok with USB !

Since 10.4.4 my external drive is no more recognized using firewire, but it mounts perfectly with USB
Using FW request me to reinitialize the disk, but then, the apple disk utility it is unable to reformat!
then I unplug FW , sets USB and everything is ok!
I connected the drive to my old IMac G4 700 and evrything is fine, FW and USB, using the same drive, using the same cable. I did repeat the test many times it is always ok with the old mac and it never mounts with FW on my newer Ibook.
I did reset the openfirmware but that was not successfull!
Then I brought both iBook and the faulty Drive to a friend (he owns a powerbook and also an external drive)
we verified that my drive does not mount on his powerbook G4 12" using FW and is ok with USB.
Then he tried his external drive and was very surprised to find the same fault with his drive and his PB using FW. (as for me everything is ok with USB!)
We are both very puzzled, our drives did work well before, (before 10.4.4 , and 10.4.5 did not improve!)
and now, with firewire,disks never mounts..
In addition I tried with the same cable to alternatively start, using the target mode, the ibook and the imac. For each test they were both recognized as external drives as they should..
So to try to sum up
- Disk mount ok with USB (1 or 2)
- Disk is no more recoknized with FW (but it was before with the exact same hadrware)
- FW Cable seems to be ok as targuet mode works properly
has anybody any idee?
It would be very munch appreciated..
thanks a lot for having read this long post..

Hi Andre, I can't remember except to say that it was mounting fine with tiger and I was able to copy files to it for backup purposes.
I just hooked it up to a PC and windows tells me the drive is not formatted. That's not a good sign, and this was stupid: I think I had the drive hooked up to my Mac Pro during the upgrade.
Idiotic, granted. But this was an upgrade, not a full install and I maybe was trusting in Apple's ability not to do extraneous stuff during an install like windows does. Oh well...
I appreciate any further ideas. Many Thanks, Frank.

External hard drive does not mount after sleep

I am using a brand new Seagate 2 TB external hard drive for my backup drive. More often than not, when the computer goes to sleep, the icon for the drive is gone from the desktop when the computer wakes up. I have to unplug it from the computer and reconnect it, then it mounts and works fine. I have it plugged directly into the computer's USB port. The drive uses USB3. As far as I can tell, it does not exceed the power requirements of the USB port. It is the only external hard drive I am using at the moment.
I should note that the same thing was happening with my last hard drive. That was a Western Digital 250 GB drive with an independant power source connected by firewire.
I am running OS 10.6.8 on an Intel circa 2009 iMac. My external drives worked fine for years, and it seems in the last year or so is when this started happening.

Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.
I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
I hope this helps.

External drive does not mount on boot

I have a Toshiba MK5055GSX 500GB external drive which I use for Time Machine but for some reason it does not automatically mount from a cold boot. Before I started to use it for Time Machine (it was formatted as NTFS at the time) I had not problems with it. All other external drives correctly mount on boot.
I had thought it might be a problem with the drive itself but if I disconnect it and reconnect it with my iMac running it mounts every time without fail. If I reboot after it has mounted it also mounts at boot. Only if I start the iMac using the power button with the drive already connected does it fail to mount and the results are consistently repeatable.
Does anyone have any ideas why this might be happening and how to fix it?

Does this drive have a separate power brick? If it does I suggest using it to see if that fixes the problem. If the enclosure has both USB and Firewire ports try using the drive on a Firewire port instead of a USB port.
It sounds like the drive is not spinning up early enough in the startup process to be detected.
Not knowing how you prepared the drive for the Mac, you should re-prep the drive as follows:
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. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC 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 HD does not mount

Hi,
I am using an iOmega FW800 & Lacie USB 100GB portable external HD's.
Both these drives don't mount after the combo update. Is there anything I can do to overcome this?
Any help would be appreciated.
Best Regards,
Aditya

Dear all,
Ive been hunting through the Support DIscussions and some kind soul has actually provided an answer (YAAAYYY!) which I have followed and it worked!
Follow the relevant instructions on the linked thread below:
http://discussions.apple.com/message.jspa?messageID=2087835
Couple of notes for those who aren't technically minded (like me)
1. Read the instructions carefully.
2. Once you have typed in the command into TERMINAL and pressed RETURN, it looks like nothing has happened. You will need to LOG OUT or restart your mac for the command to take effect. My Hard Drives power was ON when I restarted, and once I had, it mounted on the desktop just fine.
Hurrah!

ITunes does not start after Lion installation

hi,
after upgrading to the latest iTunes version and to Lion, I get "The file “iTunes Library.itl” cannot be read because it was created by a newer version of iTunes. Would you like to download iTunes now?".
Precise:
I upgraded iTunes to the latest version (from the previous one, I am a regular upgrader) yesterday afternoon around 15:00, then I worked several hours on my iTunes library (including some new buys). At night I then installed Lions. After starting Lions, iTunes does not start anymore.
I have read the threads about copying old library files from the "previous iTunes Libraries" folder. But if I do that, I will loose the entire afternoon work. Anyway it I cannot understand why iTunes now believes to be older after Lion installation than before...
Can somebody please help?

Hi,
after backing up, I downloaded the latest version again and it really worked.
Strange that evidently the Lion installation did revert yesterdays upgrade from iTunes. Now it works, including all my latest changes from yesterday.
Case solved:)

External Hard Drive not mounting after...drop

Hi all,
Not really a Time Machine question, but my wife, not realizing an external USB hard drive was connected to my macbook, pick up the laptop and the external drive dropped on it's corner...slight damage. It is a 320Gb hard drive with three partitions....two for storage and one for time machine backup. The two storage drives are mounting find and seem OK, but the time machine partition is not mounting. Disk Utility sees the partition but can't mount or repair it and gives me the error "Invalid sibling link, unable to verify or repair."
Any ideas on what I should do next (other than back up the other two drives)? Should I try erasing the disk and see if it'll mount?
Thanks,
John

If you have +Disk Warrior+ (4.1.1 or 4.2 only), or another heavy-duty disk repair app (that you're certain is compatible with Leopard), it might be able to repair the partition. DW is about $100, so unless you think you may need it for other things in the future, it may not be worth the chance.
Otherwise, if Disk Utility can erase it, it's probably ok. In this case, though, it would be worthwhile clicking +Security Options+ then +Zero Out Disk+ to be sure it can write to the entire partition.
Long term, though, I'd be a bit reluctant to trust my backups to it. (Perhaps a hint to Santa?)
Additionally, I am having trouble ejecting the two working partitions. It seems to eject them becuase they no longer appear on my desktop, but I get the "unable to eject...." error message. Not sure what this means.
See what happens after erasing the TM partition. That may clear it up. If not, try mounting them again.

External hard drive not mounting after Leopard install

Installation seemed to go ok, but when I switched on my Maxtor One Touch II drive nothing happened. Doesn't appear in Disk Utility but I can see that it is attached when I look at System Profiler. Any ideas what to try next?

After giving up on the upgrade of leopard I decided to do a clean install (to get rid of all the junk) My Lacie 800 and 400 fire wire drives mounted with no problem. It turns out my seagate fw 400 drive daisy chained off my would not mount and cause the other drives not to respond in the finder till I removed the Seagate drive and then the other two drives worked fine. I daisy chained my Firelite 400 and it mounted fine and its being used for time machine. So far haven't been able to solved this problem, the Lacie and Firelites work fine.

Mini Bridge does not open after installing 8.0.2 upgrade

I installed InDesign CS6 upgrade 8.0.2. Now I cannot open Mini Bridge.
If Bridge is not already open,
     - selecting File | Browse in Bridge... or clicking on the Bridge button: Bridge opens - good!
     - control-click on the Bridge button: I get a Reset Settings error dialog - NOT good! I cancelled this and Bridge opened fullscreen okay.
     - alt-click on the Bridge button: Two Bridge applications opened fullscreen! - NOT good!
     - shift-click on the Bridge button: Bridge opens, but Mini Bridge does not! - NOT good!
If Bridge is already open,
     - selecting File | Browse in Bridge... or clicking on the Bridge button: the ruler bars dim and nothing else happens! - NOT good!
     - control-click on the Bridge button: Bridge opens maximized! - good!
     - alt-click on the Bridge button: the already opened Bridge, plus a new Bridge, both open! - is this normal?
     - shift-click on the Bridge button: the ruler bars dim and Mini Bridge does not open! - NOT good!
My main concern is that I cannot get Mini Bridge to open at all. I can ignore the other problems mentioned above, if I can just get Mini Bridge to open.
I have restored my C: drive from backup twice and tried the upgrade a total of three times. The results are the same each time.
Does anyone have any idea what is causing my problem and how I might correct it? I am running 64-bit Windows 7 Professional SP1, 3.40 GHz Intel Core i7-3770 CPU, 32.0 GB installed memory.
Thanks greatly,
Mark.

Hi Peter,
Just to bring you up to speed on what has happened to this issue, none of the suggestions that I received in the Bridge forum helped. However, after restoring my C: drive back to prior to my updating attempts, I was able to successfully upgrade InDesign in Safe Mode (this is a Windows startup mode that blocks non-Microsoft applications from starting up on reboot). Mini Bridge is now working correctly.
Thank you again for your assistance.

External Hard Drive does not mount after connecting to airport

Hello,
I tried finding a solution to this problem already, but people that posted were having issues seeing the drive connected to the airport, while I am having the opposite problem.
After I tried connecting my USB drive my new airport extreme and it worked there and I tested speed and whatnot, I disconnected it and plugged it back into my iMac and now it will not show up anywhere, and will only show up when connected to the airport.
Basically I want my drive that was connected to the airport to connect to my mac again because it is not working.

To clarify, when you connect that drive directly to your iMac it doesn't appear on the Desktop? Do you have Finder preferences set (in the General tab) to show "External disks"? Do you see the drive in Disk Utility?

External Hard Drives not mounting after upgrading to Lion

The disks orked without issue before then I upgarde and nothing. I see that others have had the same problem but I haven't seen and answer. Can anyone help? My iomega drive can be seen in DU but can't be highlighted and is running two red lights. My Lacie brick disk has completely vanished.
I'd happily go back to snow lepord if it's a simple fix.

External Drive does not mount on desktop

Hi,
I did a Leopard upgrade and most everything went smoothly. But when I boot, Leopard pops up a window telling me that a disk I inserted is unreadable (it took me a time or two to realize it WAS referring to my USB 2.0 external hard drive).
It gives me the option to ignore, initialize or eject. Thus my hard drive won't mount on my desktop. It DOES show up in Disk Utility, however, so maybe there is hope.
So what are my options? Am I looking at burning DVDs all day so I can re-initialize or reformat this drive for Leopard?
I appreciate any help, and I did a lot of searching on this topic, so I'm aware that there may not be any solutions as of yet.
Many Thanks, Frank B.

Lacie External Hard Drive Not Recognized After It Previously Was

I have a 1 Tb Lacie Big Disk External Hard Drive that I have used for a couple years now. I have a Mac Pro, an iMac and a G5 computer that I have previously used with it. After I transferred it between computers yesterday suddenly it will not show up on any of the computers. I have tried different cables and inputs, computers, other hard drives with the same cables (they worked), restarting the computers, etc. The hard drives powers on like normal and you can hear it running, the blue light comes on in the front, but it never gets the disk loaded on the computer. There is a "auto/on/off" button on the back that I have tried switching between but nothing seems to work. Please let me know if this is a common problem and any way to get it to work as I would prefer not to lose the information on the hard drive, especially when it seems to be functioning just fine aside from not appearing on the computer.

Even backups need backups too.
And a 'good' case is one where you can pulll the drive out and pop it into your Mac pro drive bay.
power supply bricks are known issue.
Mac OS updates that affect those models.
LaCie almost by their own invented the term and idea "reset firewire bus" routine after all.
Years and you can assume not forever but eventually it could and will fail.
I'd pick up a "spare" or replacement unit, one with eSATA/FW800/USB3
http://www.macsales.com/firewire
CallDigit 2 x SATA plus 2 x USB3 $139 - USB3 card and interface works better even on legacy (how long and old is USB2 now?) USB drives.
