Xserve won´t mount LaCie Firewire drives

I booted our Xserve with two Lacie´s 1 TB Firewire drives attached and after the boot xserve wouldn´t mount the drives. I tried FW800 and FW400 connections, re-attach drives one-by-one, 4 different cables and also with another Xserve but still no avail.
The drives mount perfectly well on a desktop PowerMac G5 but the both of the xserve´s seems to repel the drives.
Any suggestions? our backups are running on the drives so this is kind of a urgent issue:)

of course, how stupid of me and how clever of the machine:D After unlocking the Xserve the drives mount just fine.
Thanks William, once again:)

LaCie External Harddrive suddenly won't mount via Firewire 400 or 800

My LaCie External d2 Quadra suddenly won't mount via Firewire 400 or 800, but will mount via USB 2.0.
I have:
Tested the harddrive on another computer and it works fine via firewire.
Shut down and re-boot. It had no effect.
Updated all software.
Note: My MBP will not boot if the Firewire 800 cable is connected.

I've had a whole heap of strife with my two macally enclosures over FW. I've only got them working twice together, regardless of jumper settings on the harddrives. I can plug either in fine, but if I use both together, my mac shuts down and refuses to boot. One drive is bus powered, the other is powered via the mains
I wish you luck

10.4 Installation on External Lacie Firewire Drive

Hi -
I have a number of Macs running 10.4 and each has an external Lacie firewire drive attached, with a partition for an external startup drive. I recently bought a new Lacie 250 GB Porsche firewire drive to rplace a smaller Porsche model, but I cannot install OSX 10.4 on it because the install disk does not recognize the external drive as an installation source. I have upgraded the firmware on the drive but that has made no difference. Does anyone have any idea as to what the problem might be and help me figure out how to install the operating software on the external drive? Thanks for your help.
Shelly

Thanks for your reply. The drive is actually being used on a G4 tower that's about 6 years old. I partitioned the drive into two sections: about 7GB for the operating system and the remainder of the 250GB for backup purposes. Neither volume shows up on the Tiger insdtall disk as a source for the installation (by the way, I also tried it on my G3 iBook, with the same results).

Formatting LaCie firewire drive - Powerbook G4

Hi, I have a 40GB LaCie firewire drive that is doing something funny on Disk Utility. It only shows as having 18GB available, and I have tried to delete it using Disk Utility to no avail.
+Question: Can anyone suggest a way to again totally wipe and regain my 40GB?+
Also, any suggestions on how to expand my 1GHz PowerPC G4 12" Powerbook with 768 MB DDR SDRAM would be welcome, as I'd rather keep this machine going well at the moment and save up for a new 'book, love the black version!

Hi Matt,
Thanks, I just did that, and it now shows:
*The top level says:*
Disc description: LaCie Group SA
Connection: Firewire
Total capactity: 18.6GB
Write status: Read/Write
SMART: Not suported
Partition scheme: Apple Partition Map
*Next level says:*
Number of folders:4
Capacity: 18.5GB
Available: 18.5GB

Er, I definelty thought it was a 40GB. Could it be I was mistaken, and it's only a 20GB?!!

PremiereCS3 won't start when firewire drive is removed

I've had to remove a Lacie firewire drive to reformat it on another system but now Premiere will only flash the loading screen and then dump out (no error messages, just shuts down) when I try to start it. Is there a way to start up Premiere to get some work done while this drive reformats?
BTW this drive was not used to store any media.
Thanks in advance.

Rename your PPro
preferences file.

Lacie firewire drives in series?

I've been recording audio to a Lacie firewire drive. My internal Raptor drive is full with plug-ins. I need another drive for just plug ins. Has anyone had any success with 2 Lacie drives in series? One for audio recording and the other streaming samples. I was hoping I could put BFD2 on the 2nd firewire, and some of its sample libraries. Thanks

Sure external devices can cause issues with your Mac if it's causing some kind of hardware problem with the Firewire bus-- drawing too much power, over or under voltage etc.. Some iMacs just have problems with the FW ports themselves. Sometime resetting the SMC will fix it: http://support.apple.com/kb/HT1543?viewlocale=en_US
I have two FW800 drives from OWC daisy chained and I have not had any issues at all. I would try and isolate the two drives if possible to see if the problem persists. Disconnect one of the drives for a few days and use just one drive. Then switch and connect only the other drive for a few days. Then maybe try one of them on FW800 and the other on USB. The FW400 and 800 share the same bus so it may not be any differnt testing one on each if it ends up being a power issue. I wouldn't think it's a power issue though because the external drives have their own power and should not be drawing any power from the computer. But you never know

G drive mini won't mount via firewire 800. usb ok

It hasnt been too long i bought myself a gdrive mini to benefit from the firewire 800 port. It seems that once my macbook gets warm the drive won't mount. It mounts just fine via usb. I've been to the genius bar twice and it worked both times, thats when i noticed it only happens when its warm. I was convinced its a software issue, but i dont know what to think anymore.
Has anyone encounter this issue? Any ideas of whats causing this?
Any help would be greatly appreciated

WAIT WAIT EVERYONE....READ THIS....VERY SIMPLE FIX!
My G mini 750GB drive stopped mounting.....I tried a million methods to get the G mini drive to mount and searched a ton of forums but never found this VERY EASY FIX. Try powering down your computer (imac in my case), then UNPLUG the power supply from the back of the computer....VERY IMPORTANT TO UNPLUG COMPUTER FROM ELECTRIC SOURCE. Nothing else worked for me.
Wait a minute, then plug back in and re-boot....MAGIC - freakin G mini showed up on desk top!
Good Lord why is this simple fix not all over the G mini site?????? It ought to be on the front of the box when you buy this thing! Seems no one at G mini sites talk about this and people are sending drives all over for repair!
Hope this helps!

IBook G4 won't mount LaCie external hard drive

A friend of mine, with a new iBook G4 with 512MB of RAM, is having some problem with an 80 GB bus powered external hard drive from LaCie. The problem he is having is he can't see his drive when he plugs it into his machine. He has tried plugging it in with a firewire cord and a USB cord, and neither have worked. In addition to not showing up on the Desktop the drive doesn't even show up under Disk Utility, however, the drive does show up under System Profiler. When it's plugged in with the firewire cord it says:
FireWire Bus: Max Speed up to 400 MB / sec
When it's plugged in with the USB cord, the computer says it sees a LaCie HD.
He has also tried plugging the firewire drive into another computer, that machine is also running 10.4, and the drive mounts without a problem. He has recently run software update and updated everything that was recommended, repairing permissions before and after each update.
Any ideas on how to fix this? Or, since it's a new computer should he just take it to the Apple Store he bought it at and have them replace it? Thanks so much.

Thought you could use this info about getting FireWire to work!
First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 15 minutes. plug it back in and try FW.
If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good!
Good Luck!
Cheers!

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

Mac Pro won't boot if firewire drives attached

New Mac Pro (OS X 10.4.8) won't boot if my two daisy-chained LaCie hard drives are attached (firewire 800).
I can upnplug 'em and the computer cranks right up; can then plug the drive back in and everything's fine. Wazzup?
Thanks, Bob

Similar problem with iMacG5 - if two firewire drives on bus wouldn't boot. Worked with one but erratic, also long delays opening files, finder erratic and hanging. Decided it was probably a chipset problem with the firewire bus. Since upgrading firewire enclosures problem gone away (I hope). How old are the drive enclosures. Oxford911 firewire bus has some problems with newer macs and OS. May get information on bus in "about this mac/moreinfo/firewire", or in disk utility window ("applications/utilities/disk Utility") WHEN computer is booted up with drives running.
OK, a Plug for Macpower's IceCube enclosures, bloody expensive but since I upgraded no problems. Also wiebetech.com have some cool stuff including internal SATA adaptors/cages etc.for older G5's and dual cores

Mounting external firewire drive

I have two lacie firewire 500gb drives, daisy chained, and connected to the firewire 800 port in the back of the computer. When I turn on the MacPro the drives would turn on and mount (and shut down when the computer shut down), which is exactly what I want, but recently I had to take my computer to the shop to get something fixed and now when I turn on the computer I have to manually turn on and off the drives. I tried connecting them before and after the computer was turned on to see if it would make a difference and it didn't.
Nothing is different with any of the connections or settings. Is there a trick to getting the drives to turn on and off when the computer turns on and off?
Thanks,
Steve

What was fixed? You might want to try resetting PRAM and NVRAM…

Mount USB/Firewire drive from shell or cron job

Is there a way to mount a USB/Firewire drive from the shell or possibly mount it using a cron job? Here's the situation. I have a user that keeps all of her data on her desktop or in her Documents folder. I have attached a firewire drive to her PowerMac G5 (OS 10.4.6) and successfully created cron jobs to backup her entire user folder every night. The problem is that she logs off of her computer before she leaves work. When she logs of the firewire drive unmounts and the cron job fails because it cannot find the drive. I was hoping there was a way to mount the drive using a script so that it will mount, let the cron job run, and then possibly unmount the drive afterwards. Any help with this would be much appreciated.
MacMini, PowerMac G5, iMac Mac OS X (10.4.7)

Try adding the following line to the beginning of the job:
mount -a
You may need to add u and/or w to the command after the a without any additional spaces for the mount to work properly.

XServe won't boot from any drive, but recognizes them in OS X Installer

I know I have another post here but this is a different issue, and I've already fixed that one thanks to Camelot .
I just received an 2 used xserves for work. One booted into OS X Server fine, so I scrubbed it and reinstalled without issue.
The second however never booted into an install. That is, I never found it on my network when I started it up and when I pushed the power button it would turn off immediately, suggesting that there was no OS on the disk or that the xserve couldn't find it. I didn't have a spare monitor to plug into it (surprisingly) so I just chalked it up to the fact that it was a new disk and hadn't had OS X Server installed on it.
Now I have a spare monitor, I've gone and installed OS X Server on the xserve. It boots from the DVD just fine, runs through the installer, then when it goes to restart, it won't boot from the hard drive that it just installed OS X Server on, it'll just boot back from the DVD unless I pop it out. If I let it boot up without the DVD in it, I'll get the standard Folder with a ?.
At first I thought it was the drive, so I installed OS X Server on another drive. Still wouldn't boot to that drive, so I booted from the DVD and repaired the disks in Disk Utility. Still nothing. I booted to DVD again and when I went to Startup Disk, it actually did show my disks with their respective OS X Server installs.
When I boot the machine holding alt/option, the system doesn't show my drives, only the DVD if it's in the slot.
I figured ok, this has to be the drives, so I swapped them with those of the identical xserve in the rack below, but my top xserve wouldn't boot from those drives either. Somewhat expectedly however, the bottom xserve would boot the drives that I took out of the first one.
Now I'm just stumped. Any ideas?
PS, drives are unlocked.

The EFI firmware, the SMC and possibly the disk I/O path seem good potential candidates for culprit.
Load and run the hardware diagnostics.
Reset the SMC, and reset the LOM.
I'm running the EFI diagnostic tool now. Firmware and disk I/O path came to mind, let's just hope it's not a major hardware issue

Hi Jeff,
Do you have the specs of the xserve and the version of OSX server you are trying to install? Does the Xserve have the RAID card installed in it and what size are the drive modules.

Mac mini won't mount in Firewire target mode

I connect one non-booting Mac mini to one working Mac mini and tried to get the data off the non-booting one, but it won't mount.
When I try to repair the disk using the Disk Utility from the working mini, it says:
Verify and Repair disk “disk1s3”
Checking HFS Plus volume.
Invalid node structure
Invalid node structure
Catalog file entry not found for extent
Volume check failed.
Error: The underlying task reported failure on exit

1 volume could not be repaired because

How can I get my data off the computer. I can reinstall the OS, but I have data in Application Data folder that I want to save too. Also, does Archive install save the whole user directory including Application Data?
I also have some files made in GarageBand saved in the Music folder.
I hope that someone can help me!

If Disk Utility cannot repair the drive then you may want to consider investing in a product like Alsoft's DiskWarrior…

Given your symptoms I doubt you'll be able to do anything at all, barring an erase and install, in the drive until you get the disk repaired.
