LaCie 1TB Big Disk not mounting as a shared device

Hi!
Today, I purchased a brand new AirPort Extreme 802.11n to replace my now dead NetGear WGR614. The set-up went well, but I have a query.
I also own a LaCie 1TB Big Disk connected to the AEBS via ethernet as a NAS Drive. The disk itself is set-up with Apple File Server and Bonjour Services enabled. With my NetGear WGR614, the hard drive would automatically appear in the Shared Devices column in Finder. The only way I have been able to achieve this same outcome is to log into the drive using Command-K and then adding it to the Login Items in the Accounts Preference Pane. This is so it will automatically appear connected in the Shared Devices column after a restart.
I have spent the morning searching many and varied forums for a solution, but almost all entries deal with USB connected drives.
If anyone has some information they would like to share, it would be greatly appreciated.
Many thanks in advance.
Rodger.

LaCie d2 Big Disk Extreme - failure

I think there is a serious problem with the FireWire communication between MacPro and the Lacie d2 Big Disk Extreme: I just moved to this machine, and I'm experiencing a ridiculous number of bus resets. See this from system log:
Jul 4 07:28:55 computer-di-lol-productions kernel[0]: FireWire (OHCI) TI ID 8025 built-in: 5630 bus resets in last minute.
The disk usually mounts properly, then after a while and randomly slows down to almost a halt. Very scary. This happens on two identical drives, which work perfectly if I connect them through USB. Also, this happens both in FW800 and FW400. LaCie recently released an update for such disks which is available from their website, but my drives are apparently updated. I can't move up to 10.4.10 at the moment because I am using ProTools which is not officially supported yet.
Any hints and thoughts are greatly appreciated!

Sorry for the late reply as I wasn't checking the posts. When I bought my 1TB I laready had number of other LaCie stuff, Cd writer, 500Gb and 250 Gb and a DVD writer. As I was passing the the 250 drive to my son I gave him the 1TB power supply so that I did not distrubed the cable arrangment, so I am guessing that I was using the power supply from one of the CD writers.
I really don't know how it affects it, but I am guessing that it just don't have enough beef to feed the drive or the interface. I did a internet search and I seen as a suggestion, I implemented and it worked. As I said all the disk utility software gave the drive clean bill of health, despite occasionally saying could not complete the instructions because of hardware error.
Ona different note this kind of thing happened to me before with my Canon 20D digital camera, two batteries died on me very quickly and charged very erratically , and when I bought my Canon 5D the new charger just charged them properly, so it was the charger that gone wrong but seemingly still functioning to a degree.
But if your drive is brand new with a brand new power supply, and checked your disk with some kind of utility software maybe it is your drive. I am guessing that you formated the drive when you bought it.

LaCie Ethernet Big Disk | USB Slow

Hi,
I'm using a LaCie Ethernet Big Disk (1TB) as a backup HD to my iMac. While both the HD and Mac support USB 2.0, the data is flowing at a 3.46 MB/s. I thought USB 2.0 ought, in theory at least, to run at 60MB/s.
The connection is via an Ethernet Adaptor, is says that it's Media Subtype (from the Sytem Profiler) is 10baseT/UTP. Is this the problem? Shouldn't this say somthing along the lines of 1000 baseT? Any ideas?
Thanks.

Hi Frando-
That 10base clue is part of it. Is there a switch or router between the drive and your Mac that is operating at 10? Make sure to check your cabling as often a bad cable or connection can cause a slower connect speed.
If you are accessing this drive over the network than the USB speed doesn't matter as that is not how the drive is transferring data.

Lacie 500GB Big Disk Extreme problem.

I have a Lacie 500GB Big Disk Extreme (Triple Interface), that the Airport Extreme (n) is not mounting.
It's formatted as Mac OS Journalled, and works perfectly if connected directly to my MacBook Pro by USB or Firewire.
When connected to the AE(n), I get the following error message:
"Your AirPort base station is reporting the following errors:
Disk needs repair
Errors were found with a disk connected to your AirPort Base Station. Please connect the USB disk to your Mac or PC and use Disk Utility or another application to repair the disk."
I connected the drive to my MBP and ran Disk Utility, which reported no problems with the drive at all. After repeated attempts, with various cables, I updated the firmware on the drive to see if that would solve the problem. It didn't.
Anyone else having problems with their Lacie drives, especially those of you with the Big Disk Extremes?

Am trying to get my Lacie 300GB Big Disk triple interface to work with my (new) Airport Extreme - however it just doesn't recognise it through the USB port.
Problem A - my macbook works fine with the lacie through FireWire cables (which is what i've always used), but the disks don't mount when its plugged in through the USB.
Problem B - would the Hard Drive work on Airport Extreme if I had a powered hub (with firewire ports) plugged into the USB, and then link up the Lacie through the firewire?
cheers

There is no display on Apple Thunderbolt display, when Daisy chain connect with six LaCie Little Big Disks.

Hi, Everyone,
I have aquestion with Thunderbolt daisy chan.
I have six LaCie Little Big Disks and Apple Thunderbolt Display to make daisy chan and I got a problem.
I place the Apple Thunderbolt Display at the end of the chain, and six LaCie Little Big Disks infront, and Apple Thunderbolt Display does not show anything.
If I plac the dell u2711 (DP1.1) Display at the end of the chain, and six LaCie Little Big Disks infront , dell u2711(DP1.1) displays.
If I place the Apple Thunderbolt Display at the end of the chain,and five LaCie Little Big Disks infront. Apple Thunderbolt Displays well.
Is it because the hardware limitation that Thunderbolt daisy chan can only have maximum 6 Thunderbolt deivce?
Apple Thunderbolt Display Should be DP1.2, why it doesn’t display?
My workstation running Windows 7x64 or Windows8.1x64
Thanks ,Myron

if you reduce the number of disks to 5 and the display works, I think we'll have your answer.

Lacie 2TB Big Disk Extreme Firewire 800 firewire 400 hi-speed usb2 7200 rpm sku 301201u knocked

I have a Lacie 2TB Big Disk Extreme + Firewire 800 firewire 400 hi-speed usb2 7200 rpm sku 301201u , which I have been using with an emac ( 1ghz power pc 4 , macos 10.5.8 ) for past few years.
A couple of days ago The drive was hit rather hard on side while on and up , the computer hung as the computer was up on a mac os 10.5.8 partition on this drive . Computer was rebooted and comes up on internal drive, lacie drive just made beep and click sounds ( i am actually deaf and this was what I was told ) every couple of seconds. Attempt was made to boot on CD to use latest available disk utility ( Macos 10.5). Lacie still does not show up. 15-20 minutes into this, I powered lacie down. This is when I started noticing a burned circuitry smell.I powered lacie down and disconnected it at this point.
Most Folks just suggest data recovery which can cost as much as $3000 or more which I really don't have .
I figured I open and examine the internalsof drive . I did so. The circuitry smells
like burned near the point where power comes in and the death diode is located, otherwise circuitry looks fine. One of the two drives , when taken out did not have a burnt smell and the other had a burnt smell towards the center but it dissipated in about an hour after it was taken out. There also was one loose screw inside drives chasing which ended up being one of the 4 screws that holds the disk drive's circuitry. I dont know but I don't think this could have shorted anything out but even though slim it is possible that such happened.
While I have Three DC voltmeters, I could not find the one that would accurately measure the voltage on the external power suppy to see if the output voltage on the 4 pins is accurate . I am still looking for the one meter that can do this.
I figured if I can find the exact drive in like new condition and swap the disks, if the disks are not damaged and if the culprit is actually burnt circuitry, then the drives should come up as they were as though nothing had happened.
I talked to a friend that suggested getting other cases and swapping disks but I guess that is not possible because the two disks are raided? ( raid 0 ) . I am also not even sure if the drives are raided the way they were put into use ( only through firewire 400) as the documentation suggests that only firewire 800 denotes use of built in raid0 but I am not sure. So again assumption is made that the drives are raided .
I contacted dealership of the drive which again suggest that Unfortunately it is not possible to obtain another drive like this one because it has been obsolete and out of manufacture for a long time. It is also a risky idea because if the problem is not with the drive enclosure hardware, there is a genuine risk of making the recovery process more difficult, or impossible.
This though does not follow logically. I have been able to see the exact drive with the same sku number offered as new or excellent condition more than 1/2 dozen times in the past few weeks so I guess drive can be acquired and tested before any such swap. If drives are not the culprit , I figure after a swap with a new enclosure and everything other than drives, the thing should not even be noticed and all should work as they did before the accident. If the drives are the cause , then the thing has been on 1/2 hour after the accident so the swap should not do any more damage or cause future recovery attempts any more issues than already might be there.
Any sound advice is greatly appreciated.

I tried the two good disks in the main chasis with new cables and power supply , and I could not get them to come on or show.
I put the good disks back in the second chasis with new cable and power suppy and it again shows ( prompts telling you that it sees a readable MAc OS disk and asks if you want to Initialize it ).
I put the first set together again with new cable and power supply and the light does not come on anymore . being hearing impaired , i put my head on the drive and hear this clicking sound every one or two seconds. The fan operates . The drive does not show when rebooting and it does not show on the disk utility. The drive does not smoke but smell of burned mica ( circuitry ) is still in my throat after a couple of hours.
From what I have learned the possibility exists that each drive is calibrated and the calibration is added to the control board , So like chances are that even if the two original drives are good and connected properly and everything else is good, they might and probably just wont work with a control board of another even exact drive. There are three tables / charts marked on each drive and specific locations marked on each chart which differ between drives . These I think are from calibrating the drives.
So I guess its data recovery...
Lacie Data Recovery wants $600 ( $300 x 2 drives ) if they recover data without need for a clean room , $3000 ( $1500 x 2 drives ) if there is need for clean room. If they don't recover , you dont pay , if they recover and you do not want to pay, then they just send you the damaged disk ( or perhaps keep it , or smash it then return it to you) .
There are many other data recovery services so I guess a few days to sift through them but I guess the maker reference should be the best way ( I think its actually a sub-company that lacie forwards data recovery to.
Too many factors are involved. One that will such be a secure thing to do or 6 months later you find out that someone opened 10 accounts under your name , or emptied your bank account ( thats actually not a problem because there is almost never any money in my bank account) . So security is a concern. I have encountered individuals that make it their business stealing peoples stuff from their disks. Once I even had one Tech guy which was refered to solve a problem I had , copying disks contents right in front of me for absolutely no reason. So I ask him what are you doing, and he says , I am copying everything just to make sure they are safe ( : ) )
Then there is the dalai lama , everything happens for a reason scenario. In which case I guess I have to consider the whole thing as Good Omen. and just forget about it and go on with my life ( maybe I go work in Mc Donalds : ) )
The bottom line is I can't believe that I am such an idiot not to have a proper backup system in place .
Thank you for the links, I will check them out.

LaCie 500g Big Disk getting hardware error on new Mac Mini

I accidentally unplugged the power cord on my new MacMini (it looks and feels very much like a firewire cable!) After that my LaCie Big Disk became unsearchable. It WILL mount with both Firewire and USB2.0 cables. I ran Disk Utility. I do not get the option to repair ANY permissions on either the Volume or the Disk itself only the option to "Verify Disk" or "Repair Disk". The resulting error is posted below. It is no longer searchable on the OS 9.2.2 G4 computer either.
I DO have the latest software updates. This external LaCie hard drive was Mac HFS+ formatted and working previously on OS9.2.2 and I will need to switch it back and forth between the OS 9.2. computer and my new MacMini. Have I any other choice but to reformat? If so which format will allow back and forth usage between OS 9 and OS X?

Hi Kim, I had a similar (although not exactly the same) experience to yours when I first got my LaCie (which is a d2, 250 GB) and accidentally cut power (with the power button on the HD itself) to the disk while my computer was in sleep mode. Since it was my boot drive, I also got kernel panics, and the only way I was able to get rid of them (and get a working system) was an Erase & Install of OS X. Fortunately, I was able to retrieve all my files, but you seem unable to browse it anymore, I guess that's what you mean when you say it isn't "searchable". Hope you had a good backup solution ...
What Disk Utility reports - Invalid Node Structure - is exactly the same issue I had, and Disk Utility doesn't seem able to repair it easily. Since you don't seem to use the drive to boot, you can simply reformat it using Disk Utility. I would suggest HFS+, and if you want to boot OS 9, select the "Install OS 9 drivers" option.
BTW I'm not sure whether you can get a dual-boot OS 9/OS X for Intel system (in case you'd be interested), because booting off an external drive on a Macintel requires the drive to be formatted with the GUID partition scheme, whereas OS 9 porbably only works with Apple's partition scheme.

Lacie 1Tb USB HDD not recognized, even in Disc Utility

Hi to all,
I have just bought a Lacie 1Tb external USB disk. It did not work correctly under Mac OS X but it works when I use it under Parallels. It is formatted as NTFS and I manage to use correctly under OS X my old Lacie 250 Gb (also NTFS). When I connect the drive to my MacBook Pro nothing happens or sometimes a folder appears on my desktop (with the content of the HDD, read only) and in Finder the HDD is mounted with an icon with a W on it (not the usual orange icon with usb symbol). I cannot use the HDD. If I open Disc Utility the HDD is not shown at all but it appears correctly under System Profile. If I boot with the installation DVD and the USB attached, Disc Utility (launched from the DVD) sees correctly the drive. My conclusion is that there is some software that conflict with Mac OS X in mounting the device. Someone of you has any clue to provide? Is there a way to "reset" the way MAC OS X handles NTFS partitions (if it is a problem with NTFS)? The USB disk works correctly on another Mac with OS X (I tried it at the shop).
Thank you in advance for your help and I wish you all a Happy New Year.

Thank you for your reply.
At the moment also the other HDD has the same behaviour. It looks like I screwed up the usual NTFS OS X handling What I did was to uninstall Mac Fuse completely (by disabling it and then by removing the icon from System Preferences, as described in the Mac Fuse help page). I had no need to install drivers to make the "old" HDD to work (when it worked . Also when I tested the 1TB HDD on a Mac at the shop, the Mac came with a clean standard install. The worst thing is that Disc Utility completely ignores the HDD presence so I cannot even initialize it. As I said I could initialize it booting with installation DVD but I would like to fix the issue. I removed Mac Fuse I had installed to try to reset the things... with no success I think that, even without any external software to read/write NTFS partitions, I should be able to mount the drive or at least work with it under Disk Utility, shouldn't I?

LaCie 1TB "Big Drive" vs AEBS USB Port

I just picked up a new LaCie 1 TB "Big Disk" to use as backup storage for my media library. Speed is not a gigantic issue for me as I plan to do the backups unattended at night. The LaCie has a "triple interface" and I have it plugged into my AEBS (firmware 7.1.1) USB 2.0 port. None of my computers on my network, wired or wireless, can "see" the LaCie. The Airport Disk Utility doesn't "see" the disk either. The Airport Extreme utility doesn't "see" the disk but I have disk sharing turned on and have enabled everything that "should" allow the disk to be visible. I've checked the disk out by plugging it into my MacPro using both FW800 and USB2 interfaces. The disk is preformatted with HFS+ and it is immediately recognized. Moreover, disk utility reports it in perfect condition.
I'm stumped. Anything obvious I might be missing. The disk seems fine and I've had no difficulty with my AEBS after initially setting it up. I'm open to other suggestions.

I am afraid it's not due to the USB cable.
I bought a Lacie 2TB BIGGER DISK and had the same problem.
Then I formatted again the disk with 4 partitions in a way to have 4 disks each under 500GB and now it works great!
Obviously I have 4 icons to mount and 4 icons on the desktop, but all of them follow the same settings (i.e. I cannot block the access to just one of them by password).
Does this help?

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?

MBP w/ 2 LaCie 320GB Big Disk Extreme d2 Firewire reset

I have a 15" MBP 1.83 with 2GB RAM and 10.4.6. Connected to this are 2 LaCie FW400/800 320GB d2 Big Disk Extreme drives. A FW400-FW400 cable connects the first one to the MBP and the drives are connected to each other with a FW800-FW800 cable.
When scrubbing through video on these drives, often there will be a knock sound as if the drive being read from has parked and then the video tool (VLC, QTPlayer etc.) will hang for 5-10 seconds... then all is well.
What is causing my drives to behave like this - it does not happen when they are hooked up to my ALBook PBG4.

Time Capsule Disk not mounting

Since a couple of days, my 2 TB Time Capsule (1st generation, software version 7.6) disk (2 partitions) will not mount. Neither does it show up in the TimeCapsule preferences list. It has a wired ethernet connection with my MacMini and I use AirPort with my MBP and iMac. AirPort (sofware version 5.5.3) still works. I tried resetting, going through the fast-and-slow amber blinking lights, and the light on front is green again. What is the problem and do I get access to my data?

I'm curious: How did you manage to partition the internal disk of your Time Capsule?
The first 2TB Time Capsule was a 2nd generation model.
Neither does it show up in the TimeCapsule preferences list.
Please explain what you mean by "the Time Capsule preferences list".

Disk not mounting in Target mode. Other options?

I had a disastrous snow leopard upgrade that has thrashed my hard drive on my MBP. It is strange because my iMac upgraded with no issues and is a more 'complicated' system to upgrade.
I get an invalid node error message when verifying the disk. I cannot boot the OS from the hard drive anymore. Attempting to do an OS install gives me an error message that the contents of the disk cannot be changed.
When I launch the OS from the snow leopard CD, I am able to get to the file system via a Terminal window. There are a few files that I would like to salvage if possible before doing a reinstall of the OS. I tried setting the MBP to Target mode to access from the iMac, but the drive does not mount (only the DVD drive mounts).
Are there any other options? I can also get to these files in single user mode. I would like to physically get them copied somewhere outside of the system if possible (instead of moving them to a different location on the drive and doing an install).
Any thoughts would be greatly appreciated.

Hi Andy Manson;
The invalid node error message indicates serious problems with the directory for that disk. This could be the reason that you are unable to boot.
You might try a demo copy of Data Rescue II to see what it salvage in the way of files from the disk.
Since AFAIK DiskWarrior is not ready for Snow Leopard yet that only leaves you a reformat of the drive to repair this problem.

Startup disk "Not mounted", needs to be repaired but can't get it to mount

I did a Verify Disk because my HD has been having issues. It told me I needed to backup and reformat, so I went ahead and backed everything up and went to DU in recovery mode.
But when I got there, my Macintosh HD showed up as "Mount Point: Not Mounted", so I did the following:
I clicked on the Macintosh HD from the list and clicked "Mount". It gives me the following:
Mount failed
The disk "Macintosh HD" could not be mounted.
Try running First Aid on the disk and then try mounting.
So I click "Verify Disk" and it gives me this:
Disk Utility stopped verifying "Macintosh HD"
This disk needs to be repaired. Click Repair Disk.
So I go to click Repair Disk but it's grey and cannot be selected, I assume because my drive is not mounted.
So how can I'm in a paradox and REALLY need help with getting my startup drive mounted again. Can anyone help?
Let me know if I can provide more info for troubleshooting and thank you in advance!

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
