Firewire 800 external drive not found!

My power went out last night, so this morning my external drive is not on my desktop. It isn't read by my computer. I tried it on my other G5 and it reads it, but for some reason it won't show up on this one. Could my settings be screwed up? Please help! I'm not a mac genius yet.

A. buy a UPS
B. Unplug your G5, your FW cable, power to the FW case.
C. Let sit for 15 minutes.
If it won't show up now, try either SMU/PMU reset, or reset nvram in Open Firmware.
FW seems to be very iffy when left on. I have found it best to unmount and power off when not in use (though FW800 seems better behaved). SATA doesn't have the problems fw does.
When you had it show on the 2nd G5, did you check it out with Disk Utility?

I need a firewire-800 external drive tower

I currently have several external hard drives each individually connected via FireWire 800, all drives chained together via the FireWire 800 in-out connectors.
What I really need is a 4 or 5 bay hard drive external tower of some kind to reduce desktop clutter. And a tower that has FireWire 800.
I've found several 4 bay storage towers but that all are for RAID usage.
I don't need RAID. I'm not even sure if I could disable the RAID part, and just use the tower simply as external storage/expansion (which is what I want)?
I've read some of the user manuals on these RAID towers, and it seems the units are meant for RAID use only.
I don't know much about RAID, except that it mirrors one drive onto another as a safety backup.
Does anyone know where I can get an external 4 or 5 bay tower with FireWire-800 for extra storage only? No RAID needed.
Or... can the RAID towers just be used as external storage?
If so, how might the RAID feature be disabled? Or can it?

Firewire 800 external drive no longer mounting

My firewire 800 external hard drive is no longer mounting on my MBP. It powers up, spins, but has no reaction to being plugged into my computer. I've tried connecting it and the turning it on, and connecting it while it was already turned on. I've tried different cables and different types of adapter cables (fw800 to 400, fw800 to USB, etc.), but there is no communication between my drive and my Mac. Same goes if I connect it to my wife's Macbook, or my iMac at work.
I recently had the logic board and left i/o board replaced on my MBP, I'm not sure if this is relevant since the drive has worked since the replacements and I get the same results on other Macs.
What should I do next?

who makes the drive set up?
OWC for example has a history of bad power supplies that make the drive not accessible (drive spins up but never spins all the way up)

Firewire Hubs For Use With A New Firewire 800 External Drive

I currently have 3 HD daisy chained to one of my Firewire ports. I have an older Firewire iPOD with a dock that is attached to the other Firewire Port.
I need more storage capacity so I am planning to get 1 Tetra La Cie - this model. I have had excellent experiences with LaCie.
(LaCie 301442U d2 Quadra Hard Disk 1TB eSATA/FireWire800/FireWire400/USB 2.0 External Hard Drive (Aluminum).
I would be using the new HD as a Time Machine Device and possibly as backup for my music library which is currently on one of the external HD's and backed up to a second HD.
I don't have available ports.
Are there Firewire Ports which would be functional?
Should I be considering some other sort of configuration?
This is an iMAC 24" bought in October 2006
Thanks

My music library is housed on an external hard drive so Time Machine can't be used since it requires an operating system on the source files...
That's not true. You can back up files and folders on an external drive using Time Machine, as long as they are not on the same volume as the Time Machine archive. You just go to System Preferences +Time Machine+ pane. Click on the Options button. All external drives are on the +Do not back up+ list by default. Remove the external drive (with your iTunes files) from this list of things excluded from backup.
If don't want to include everything on that external drive, put the folders you do not want backed up on the +Do not back up+ list. What I've done for my external FireWire drive (which is my primary data storage volume since my internal is only 160GB) is create two main folders. They are called Documents and +Documents (not backed up)+. They serve as an extension of the user account folder on the internal drive. Files and folders I want backed up go into Documents. Files and folders that are non-critical go into +Documents (not backed up)+. So then, the external drive volume gets removed from the +Do not back up+ list, so that Time Machine backs it up. But I put the +Documents (not backed up)+ folder back on the +Do not back up+ list so that only the Documents folder gets backed up.
If you do daisy chain off the FireWire 800 port, be sure to put the 800 drive first on the chain. Putting the 400 drive before the 800 drive will reduce the speed to the 800 drive to 400 speed.
perhaps the beach ball I often get when working with iTunes is a product of the speed of the data being accessed on the external hard drive.
My +iTunes Music+ folder is on an FireWire 400 external drive. I do not notice any issues with iTunes accessing the files. That drive is attached directly to the iMac's port with no daisy-chaining behind it. If the free space gets low, the files and remaining free space will get more fragmented, and that can also cause such issues.

Can I add Classic on a Firewire 800 external drive?

I stupidly bought a CD that needs Classic to run. I don't want to install Classic on my main system. Can I install it on a Firewire 800 external and expect it to work?

I remembered I had an old backup of a friend's Classic system on a LaCie Triple Interface drive. I connected it via Firewire 800. OS X found it, modified it, and aksed me to restart Classic. It worked fine. I was able to view an outdated presentation CD which required either Mac OS 8-9, or Windows.

Thunderbolt to Firewire 800 external drive problems

I recently upgraded from a MacBook Pro 17" early 2011 to a MacBook Pro Retina 15" (early 2013). I have a Drobo and two Seagate 4TB external drives, all connected via Firewire 800. So, I added a Thunderbolt to Firewire 800 adapter and, it seemed, life was good.
I keep my large iTunes Movie and TV show collection on the Drobo. Since transitioning to the new MacBook, I have had a number of issue with watching movies on my Apple TV 3. Randomly, and periodically, the movie appears to be corrupted - the audio track skips/loops and the image is horrible macroblocked, as if the file is damaged. When I check the movies on the Drobo, opening it with Quicktime on the MBP, it plays just fine at the same spot it appeared damaged on the Apple TV 3.
A second symptom is this: I can no longer re-encode video with Handbrake with the source and target files on the Drobo - it gets some portion of the way through and it just stops, leaving the video partially encoded; again, at random locations/offsets into the video and not the same spot twice.
My initial thought is that connection to the Drobo is dropping out and coming back, on its own, but long enough to cause the above problems.
Is anyone else seeing this issue or something related when using the Thunderbolt to Firewire 800 adapter with large drives?
Thanks, in advance.

Update: I exchanged the Thunderbolt to Firewire adapter and the issue persists. I have a Drobo that I used with my previous system, a PowerMac G5, and never had any issues like this.
It does not matter what software I use. But at some point video playback will suddenly become garbled. If I start the video from the beginning, sometimes the garbled video will start sooner but never later. A restart temporarily resolves the issue. If I copy the file to the local hard drive the video will play back garbled. This is indeed a very strange issue. The issue behaves like a bandwidth bottleneck.
I was having this issue prior to upgrading to Mavericks.

Firewire issue--Backup drive not found w/Time Machine after imac sleeps

I've had a lot of problems with Time Machine on my G4 imac since starting to use it a month ago. I think I have isolated the problem:
Time Machine functions properly while the computer is in use, and it has no problem after a restart or shut down, but if the computer goes to sleep and then TM runs its hourly backup, I get an error that it cannot find the Backup Drive. Once this happens, TM will no longer work until I've deselected the drive in TM, unplugged it, plugged it in again, and reselected the drive as the backup Drive. Sometimes this requires a shut down or restart too.
Here's what I've tried:
1. connected the drive via USB--it operated without a problem
2. unplugged all devices from the computer, shut down, waited, 20 mins, restrted, plugged the external drive back in via Firewire--the problem persists as described above.
3. deleted the TimeMachine.plist file, restarted--problem persists.
I've read that the Firewire port can be reset with other procedures such as zapping the PRAM or updating the firmware. I've also read that new problems can arise after reseting the PRAM so I'm hesitant to do this. Can anyone shed some light on the PRAM option?
I cannot find where the firmware updates are located on the mac site. Could someone point me in the right direction? I've looked under downloads and after searching, came up with a long list, but nothing was labeled clearly. Each listing mentioned firmware in the header, but it seemed to always pertain to a certain issue (eg. superdrive, or installing appleworks). I could not tell what was the most recent firmware released for my machine, and I fear installing something retrograde that will create new problems.
If anyone has any thoughts on how to deal with the firewire problem, or if you think my issue with using a FW connected drive with Time Machine might be rooted with something else, please comment.
Thanks!

It's possible a heavy-duty 3rd-party disk repair app can fix it, but they're expensive (DiskWarrior is about $100), and there's no guarantee it can do it.
Am prompted to reformat but I don't have a good understanding of what this means and how to do it.
That will erase it. See Time Machine - Frequently Asked Question #5.
It sounds very much like the disk is beginning to fail, although it's possible there's a bad port, cable, connection or power supply (if it has its own).
I'd suggest getting a new one, and using it for your Time Machine backups; once you have a good backup there, reformat the old one (and select Security Options to write zeros to the whole drive -- if that fails, you know the drive is toast). Use it for secondary backups, per FAQ #27. If it has failed, get a second new one for secondary backups.

Firewire 400 External Drive Not Recognized in Yosemite

I have a Fantom external hard drive that is plugged into my Mac mini. The external hard drive uses the old firewire 400 standard. The mac mini only has a firewire 800 standard port. I have an adaptor to bridge the two, and this worked fine until I updated to Yosemite. Now the drive isn't recognized. Can anyone offer suggestions on what to do to get this drive to work on this computer?? None of the other macs in my house even have a firewire 800 port anymore.

Daisy chain from Thunderbolt external drive to Firewire 800 external drive?

Can I go from a Thunderbolt external drive, using its second thunderbolt port via the Apple Thunderbolt/Firewire adapter to a Firewire external drive?

Sharon,
did you do anything else besides copying your library to a fire wire drive after your last post Aperture not responding ?
Since that library probalbly already needed fixing, I'd recommend to force quit Aperture and use the "First Aid" to repair your Library.

Firewire 800 external drives

Do external drive enclosures supporting Firewire 800 and 1TB drives require a brick power supply or can they be powered via Firewire 800 by the Mac Pro?
Thanks!

Can iMac iSight (2 firewire 400 ports) use a Firewire 800 external drive?

If I don't get more than 400 data transfer speeds I don't mind- I may buy a new iMac next year anyway but will it work at all now?
I'm looking lustfully at a Western Digital My Passport Studio Firewire 800 320Gb poertable external HD.

Thanks guys, I've attributed points accordingly, bonus smugness goes to anyone who might point me in the direction of an "appropriate cable". Oh... and I'd like the moon on a stick please. Seriously though, thanks for the advice, I'm going to wait for the Western Digital Firewire 800 version of their My Passport Studio portable external hard drive to become available in the UK.

Firewire 800 external drive reccomendations for mavericks time machine?

I think I need a new back up drive after upgrading from Snow Leopard to Mountain Lion to Mavericks. I like using the firewire 800 port so my others are freed up for other peripherals. Any suggestions? I've not been happy with the reminder that the WD I got a t the Apple store can't be read. Any suggestions?

Are you saying that the WD drive doesn't have FW capability?
If you need to purchase a new EHD the drives suggested by Allan are very reliable. I have 7 of them and have had no issues.

External drive not found

For some reason, both of my LaCie external hardrives and my external DVD burner won't mount on the desktop. I need to take files off of my computer cause the start up disk is almost full but if nothing will mount on the desktop how can i get my files off?
How do I get the drives to show up?

Hi! If the DU can't see the drive the firewire/usb bus may be tripped out. Resetting the pmu may get it working again. It's unlikely that several drives would all fail at the same time. Some early g%'s had the pmu/smu reset button but the latter ones require unhooking everything and letting them site for 15-30 minutes to reset the pmu/smu. Tom

Firewire 800 External Hard Drive recomendations for recording

Ok so I posted a week or so ago about a bad experience I had with a firewire 800 external drive. Anyway, Im sending it back and getting a refund but I wanted to confer with you guys about a good, but cheaper (under $100 please) firewire 800 drive thats good for recording to. This will be my recording HD. Can anyone recommend some for me? and shooting a link to a place that sells it would be appreciated! ..and the more recommendations the better

Hi Veena, Welcome to Apple Discussions.
And you've tried choosing the volume and pressing the "Mount " icon on the tool bar of Disk Utility?
Have you shut down your Mac and disconnected your firewire cable from both ends and let it sit about ten minutes then reconnect and try. Also, it is important to disconnect the AC power to your Mac, this helps to reset the FireWire port(s).
Do you have TTP or DW, both of which you could use to try to mount it.
It is also possible that you have a bad cable or a bad port, do other FW devices work?
