Unknown Device Lacie Firewire DVD+/-RW

I have a Lacie dvd+/-rw 8X4X12 F A Porsche firewire that my mini won't recognize. Profiler say's its an unknown device. I had it working when I got it this summer, with panther, but remember it being a pain it the harddrive to install.
None of the software finds it including iDVD, Toast, and I tried patch burn today. Nope nothing. Tried the firmware update too. Seems to work OK with windows. I haven't needed it with Tiger and now I do.
Fairly new to Mac so please help.

The firewire bus reports it as an unknown device and gives it the standard firewire atributes of 400mbps. I can be more accurate if thats what you need but I am not on the mini at the moment. It is not listed under disk burners.
I have a lot of other equipment running through a router thing(?) including a Hard drive, Audio in/out device, and sometimes a Mini DV. None seem to have a problem. I tried the Lacie solo at least once, nothing. Also, since I posted I tried Lacie's utilities again and still nothing, although the firmware updater mentions a dvdrw in parenthases, but doesn't need to update it.
It's a mini nightmare alright.

Panther to Tiger using LaCie Firewire DVD drive

First, it was suggested I start a new topic, because of using an external Firewire drive. I have the proper Tiger "Retail" install disk. This is for a friends iMac that did not come with a DVD/Combo drive.
Anything anyone can suggest. I'm hoping the following will work:
1. iMac has latest firmware, and is up to date with latest Panther.
2. hook up LaCie external firewire DVD drive, and as long as it is recognized on the desktop of my friends iMac, that I will be able to then insert/load the Tiger Install Disk and double click on it to install Tiger onto the iMac.
3. I additionally have the option of taking over my Intel dual-core MacBook (Leopard installed) and using that in Target Disk Mode with the Tiger disk in the combo drive of the MacBook. Will it then install on the iMac?
4. I appreciate any and all suggestions and help. I read through numerous posts, but all the links for the Applelink article about installing using Target Disk Mode simply take me to the main page of Applelink and I can't seem to find the instructions.
5. I'm just wondering anyone's experience in using an external Firewire DVD drive to use as the install disk for the OSX Tiger installation to an older iMac.
thanks! Patrick.

Hi Patrick, and a warm welcome to the forums!
1. Good.
2. Should work if it's Mac compatable, you'll find out soon enough.
3. Very likely.
4. The iMac should see the MacBook's DVD as bootable when the MB is in Target Mode.
5. It works with many FW Opticals, but a few do not support Mac Booting.
6. Another option possibly, you can clone an image of the DVDs to a FW drive and boot from that for an install too... I've used Toast to do it, but it can be done with Disk Utility.
PS. I doubt you'll have problems with 2 ways to go there, good luck!

New Quad G5 - 'unknown device' on Firewire Bus

Even when nothing is connected to the Firewire ports, and after rebooting, System Profiler shows an 'unknown device' on the Firewire Bus. The Firewire bus works correctly, I've used it with hard drives and a Focusrite Saffire audio interface. The unknown device is always in the list.
Other Quad users seeing the same thing?

same thing for me, I think it's not something wrong.
Like there is hub integrated firwire hub...

DVD Burning Error: Unknown device error. (0x73, 0x03.)

I have been trying to burn a home movie using iDVD. I transferred the media successfully to my computer, followed all the steps, and was finally ready to burn the DVD. After waiting almost an hour through the burn process, it spit the DVD back out of my Macbook Pro and gave me the following message.
*Errors were found during the burning process:*
*The recording device reported the media error: Unknown device error. (0x73, 0x03.)*
I don't really know what this means. Was the media corrupt? Or is there a problem with my DVD player? I have supplied my DVD and computer information below. I would appreciate all the help I can get. Thank you in advance!

Using the same media I've used for years (Verbatim 4x InkJet printable) and all of a sudden can't burn from the internal drive. I do have an external burner (7 disc standalone replicator with USB/FireWire 400) and hooked that up and burned to a disc from the same spindle with no problem, and then made a 3x replicate with the same media. So it's looking like my MacBook Pro's drive is failing?
Laptop is plugged in and fully charged.

When I plug in my Lacie Firewire 800 drive it causes certain apps to crash. Chrome will immediately crash when I open it, so will DVD player. It's only when I plug in my Firewire 800 drive, USB does not cause issues. What's the deal?

IBook won't load Firewire drive; "unknown device"

That's the summation via System Profiler. It's a SmartDisk Firelite enclosure but I swapped the old 40 GB drive that failed for a new Seagate Momentus 80 GB drive. My G4 dualie recognizes the new SmartDisk setup fine. It loads immediately and I was able to access via all the utilities. Transfers work well.
But on the 1.33 iBook the green light appears on the SmartDisk enclosure, but no threat of loading. Only System Profiler identifies something, "unknown device" with 400 capability. When I remove the firewire cable, System Profiler doesn't see anything.
I had no trouble with the SmartDisk prior to the old drive failing. It worked perfectly on the iBook. My firewire port appears to be okay, since I tried Target Disk Mode with the two computers and it worked well.
Any suggestions would be greatly appreciated. I Googled and found many issues of "unknown device" related to firewire drives, but none that seemed to precisely fit this case, a drive that was recognized on one computer but not another. Both are running 10.4.11.

I'm still baffled but tonight I found an acceptable alternative, a Macally 250 Firewire/USB enclosure that I had in my closet but never used previously. The Seagate drive loads on both the dualie and iBook using that enclosure, which is bulkier than the SmartDisk but right now I don't really care.

IMac shows firewire hdd as "unknown device"

Hi,
I have an Iomega firewire hdd, that a few months ago worked fine with my powermac. Now I have an iMac Intel and it shows the firewire as "unknown device". I've tried plugging the firewire hdd into two different iBooks and got the same result.
When the firewire hdd in plugged in, its blue light comes on. But I can't hear the hard drive working (though I can't remember if it made a noise when it was working properly).
Unlike another post that was similar to this, I cannot change the jumpers, as it is a closed unit.
Does anyone have any ideas?
Thanks!

hmm, sounds as if either the HD has died/ has a loose connector, or the firewire controller had gone kaput, its not that common but can happen, and seing as you have tried it on 2 other Ibooks and still have unknown device that seems to be the case.
I have had an external enclosure that had firewire and it stopped working but when i took the HD out it worked find, just the box died..
as yours is a sealed unit id hope its still under warrenty
Sorry i couldnt be more helpfull

Firewire Bus/Unknown Device?

Hello to all. I just picked up a New 2.3GHz Power Mac and when I was checking the System Profiler in the Firewire section it reads Firewire Bus
Unknown Device
FireWire Bus:
Maximum Speed: Up to 800 Mb/sec
Unknown Device:
Manufacturer: Unknown
Model: Unknown Device
Maximum Speed: Up to 400 Mb/sec

The funny thing is I have nothing plugged into any of the Firewire Ports! The other strange thing is I have a 20 inch Cinema Display (which has a USB and Firewire Hub built into the back of the display) and If I plug that Firewire plug into the Computer I get a Duplicate reading of the info above (looks like this):

I called Apple and They had me run every test under the sun. As a last resort They had me erase the Drive and do a reinstall of just the basic Apple Software and this is what I ended up with. I thought maybe one of you kind folks might have some idea of what the **** is going on.
Thanks

Thanks so much for your replies. So what is the technical explaination for this because I have been on the phone with Apple for hours over the last 2 days send them all sorts of system data. I even mentioned the fact that I have seen postings listed on this forum with other people with the same Unkown Error issue happening to there Dual Core machines and the people I have spoken with at Apple are acting like the have never heard of this before. I only noticed this Unknown Device thing because I am in the Audio Recording business and I am having a problem with my Digidesign DIGI002 interface giving me this slight distortion problem coming out of the 002 unit. But this was happening when I had the 002 connected to my Powerbook 17inch 1.33. I figured it was some type of software issue but now I'm checking into the 002 as the culprit! And the people down at Digidesign have never heard about this Unknown Device Issue as well and think that could be messing up the 002 but I do not have this Unknown Device thing going on with my Powerbook. So I'm stumped!
Thanks again!

"FireWire Unknown device" - but nothing is connected!

Hi everyone,
although I have no FireWire devices connected, System Profiler keeps showing an "Unknown device - maximum speed 400 Mb/sec".
Seems like the FW bus retains the memory of something that was connected at some time, but I cannot reset it. I ran through the suggested "unplug everything, shut down and wait 30 minutes" method, with no positive results.
Problem is, my Avid Mojo will not run if it thinks there is anything else connected to the FW bus.
Anyone have any ideas on how to reset the FireWire bus?
Thnks a million!

Hi Roberto Servera-
Did you look with everything except mouse unplugged?
Have you tried removing any PCI cards if present?

FIREWIRE DRIVERS for G5. Unknown Device Message

I updated a G5 that originally came with 10.3 to 10.4. When I did it, I lost the Firewire Drivers and it reads Unknown Device.

Hi. Well - Apple FireWire "trouble-shooting" is here
http://docs.info.apple.com/article.html?artnum=303598
but I would check the website of the device manufacturer for up-to-date drivers - and possibly try a FireWire reset, bottom of the page here
http://docs.info.apple.com/article.html?artnum=88338
If none of this works, re-installing the combo OS X update may help. (Personally - I disconnect all FireWire devices while updating - I still remember the amusing 10.3.6 incident...)
Good Luck.

Question for Mike - LaCie FireWire & iDVD5

Mike - Can you help please ? John Beatty suggested I post this to you :
I have just bought a LaCie Double Layer bus-powered Firewire DVD. It is an NEC DVD+-RW ND-6550A device. The drive came with Toast 6 Titanium, which is now installed.
I also have an internal Matshita DVD reader/ CD writer as part of the original G4 setup.
When I attempt to burn a project in iDVD5.0.1, the internal drive opens up and I get a message telling me to insert a DVD, even though this is not a DVD writer. I've tried Control-clicking the Burn icon, but nothing different happens. There is no option for drive selection in the iDVD menu structure either.
I don't really want to spend ages writing Disk Images, then writing to the LaCie, and I've searched this forum for a similar issue - but 'fraid I can't find anything similar. Does anyone have any suggestions that will enable iDVD to recognise the external LaCie ?
Appreciate any advice

RE: How do I get iDVD5 to recognise my external DVD Drive ?
Don't skip this route - the amount of "extra" time is almost zero - in effect iDVD is doing this anyway behind the scenes to some degree. And separating encoding from burning makes a lot of sense. I always "Save as Disk Image" and burn separately.
And there is a guy that works for LaCie that frequent this forum:
http://discussions.info.apple.com/webx?224@@[email protected]/7
I think you just need the proper disk burning profile from LaCie. You could probably e-mail Mike at the address on his profile. Or post a new thread titled "Question for Mike - LaCie Firewire and iDVD5"
John B.

Mike
Thanks. I tried burning a disk image for a 48min video in iDVD. That worked fine when previewed. I then burnt it to DVD in Toast 6.1 using the Copy (Image File option) Tab.
The resultant DVD will not play in either my internal Drive, nor my normal DVD player - which is a multi region player. The DVD is only recognised in the external LaCie. BUT, playing the movie only shows chapter 1 of 12, and there is no sound at all. (despite the preview showing it to be ok).
As a test, I burnt the movie in iDVD5 using the Pfurz & Hurz plugins. It burnt ok, but I got the same result - chapter 1 only and no sound.
My supplier for the LaCie rive suggested I also try and export the movie from iMovie to a Quick Time compression at full DV quality to make sure that worked. It doesn't - despite a 35Gb spare capacity on the Hard Drive, I either get a complete system hang with hard restarts required, Error 36 or the occasional short clip compressing OK. I'm at a loss - the fact that I get a decent image file from iDVD indicated there's nothing wrong with the video files...
Any suggestions ??!

IMac G5 won't recognize firewire DVD burner

Hello, all! I just purchased a LaCie+/-RW DVD drive (FA Porsche design) with firewire. From my first attempt to hook it up, my computer won't recognize the device. System profiler shows the firewire ports listed (400 speed) but the DVD drive doesn't show up either in profiler or on the desktop. I have tried: 1.) Resetting PRAM. 2.) Resetting SMU. 3.) "Resetting" the firewire ports in the same way that others have been advised to do in this discussion thread. 4.) Switching the firewire cable to the other firewire port. Yesterday I took the DVD drive to another Mac (G4 Tower) and it worked beautifully, so I'm certain that the cable, brick, and the drive itself are fine. Any ideas? What would be my next step to take so that I can burn on DVDs?
Also, if I picked up a firewire to USB cable/adapter, would that do an adequate job of transferring the data or would I be wasting my money?
Thank you in advance for your helpful suggestions,
Boring Teacher

Good morning, DP! I've never hooked up any firewire devices to this machine before, so I can't be sure that the ports have ever worked! If by "optical drive" you mean the mac's CD drive, it's built in. I have three external USB ports, two of which are taken up by the keyboard and mouse. The other USB port has worked fine for swapping in the occasional camera or iPod.
Thanks for the interest, I'll wait awhile before I take it in to a service desk!

Unknown Device Error (0x0C, 0x00.) When trying to Burn

The past few days i've run into problems trying to burn from my Mac Book Pro.
In DVD Studio pro i get the " Unknown Device Error (0x0C, 0x00.)" when I try to burn from the burning on the computer.
I even tried burning from an external Lacie drive and I get the "Unknown Device Error (0x30, 0x05.)
I've cleared up hard drive space i have 5 gigs free. And I've tried restarting many times. I haven't run into problems like this before.

Hi
That can be caused by bad quality media. Read here about * about quality media * and try allways to use first quality group.
Besides that, DVDSP is not the best burning software at all. My prefered workflow is * Creating Disc Image in DVDSP * and burning it with Toast or Disk Utility.
Hope that helps !

Fix for "Unknown Device" when the iPod is connected

After a few long nights, a few headaches, hours and hours of reading, thinking and many toasted sandwiches, I finally found the problem to my iPod not loading. Putting together information I had read here and at many other sites I had a brainwave... and sure enough it worked. I figure this may be helpful to many other iPod users, so... here I am posting my solution. Note though, this wont help all users, but I know I wasnt alone with this issue, and this just might help someone.
Ill list the issue I was having (this may help other people identify their issue to mine) was that the iPod failed to work on windows, and threw a fit when plugged in. Windows did too, iTunes would lock up and the iPod software failed to recognise that an iPod was connected. The iPod had worked on an older PCs before, but it failed to work on my new homebuilt PC. When I first connected the iPod it began to work, transferring and updating.. but then it unexpectedly disconnected the iPod.. and mentioned something to do with an I/O error, the iPod had to be disconnected and it also mentioned something to do with a timeout error and dataloss (or as it put it Data has been destroyed. Thats always a pleasant message to read). Suddenly, half the music on my iPod wouldn't play, it skipped songs until it found a song it would play... really annoying. I tried to format the iPod using the iPod software... buuut it told me that it wasnt an iPod that was connected (Funny that... lol). After the first iPod crash, it would react differently when connected. It would once again pop up with the Found new hardware bubble, Apple iPod..., Disk Drive... ... then iTunes loads... then iTunes freezes... then the iPod disconnects 2 mins later, then iTunes unfreezes. THEN the next time the iPod is connected, it would say it was an Unknown device, and that it has Malfunctioned.
It seems that, oddly enough, my iPod (I own the 30gig iPod Photo) does not like USB 2.0... Im thinking that it must not support some of the device commands the PC is sending to it... Weird though, because on other USB 2.0 PCs it worked fine. (I got the best results out of Dell PCs...). IF USB 2.0 is disabled and slows to USB 1.1 the iPod works a charm... jumped up without an issue in the world. To disable USB 2.0, jump into BIOS as your pc is in its POST stages... this being, when the PC is first turned on and presents a message such as Press DEL to enter setup (or something similar), do so. Then refer to your manual on how to disable USB 2.0, if possible. Apply the changes and reboot. Be sure not to mess around with other settings, it is very easy to mess up your computer if you change settings you are not familiar with.
Other solutions would be to run the iPod via Firewire... if you can get a cable. Run along to your local mac store and see if they have one in stock. Ill get back on here to post if using Firewire solved the issue later.
Perhaps a motherboard BIOS upgrade, or newer drivers could resolve the issue. This may explain to some people why their iPod stopped working overnight after working fine for so long, maybe an update of the sort was installed. Apparently my motherboard already has an update, so Ill test that sometime and post my results as I investigate further, but as for now Im just happy my iPod is working, even if it is taking ages to transfer (25 gigs of music takes awhile over USB 1.1 lol...).
Also, I might add that my motherboard is an ASUS P5P800 with the Intel 865PE chipset. It could be an interesting pattern seeing which motherboards do not seem to be compatible with the iPod at USB 2.0 speeds.
As long as this post was I hope that someone gets some use out of it. Ill post further findings as I investigate this matter further.
Happy iPodding!

hi Jazza!
the best explanation for this that i've seen is that there can be power drain problems in USB 2.0. drop below 500 mA running through the port and everything goes to pot. this may well explain why switching back to USB 1.1 sometimes works like a charm, and also explains why it's important to have the ipod plugged into a high powered USB port rather than a low power port.
i've seen a confirmed case of a USB connection going west after a scanner got plugged into the beast in question ... periodically i see other reports along these lines, too.

There could be a few reasons, a common one is bad DVDs or a burner going bad.
