PowerPC :: Firewire Ports Not Recognizing Anymore
May 21, 2010
My powermac G5 has been off for a week while I was moving apartments. When I plugged it in again the external harddrives (four in all) that were daisy chained through the two firewire ports aren't being recognized anymore. I thought it was a bad cord or insufficient power but nothing worked. When I finally got around to looking at the System Profiler and check Firewire it said, "Unable to list firewire devices". I admit that I'm at a loss and I have no idea how to troubleshoot this.

Well I have this problem on my iBook. At first I thought it was just my printer, but now I have it with my iPod. I plug anything in to the usb ports and it is connected by my ibook doesn't recognize anything I plugin. My iPod is sitting here on do not disconnect, but it doesn't show up on my desktop or in itunes. When I plug in my Epson printer and try to print, it wont connect to the printer, but the printer is on and the connection is good. They both work on any other computer in my house. I go into system profiler and when I click USB it just has the loading wheel going. That's all I get. The weird thing is that my mouse which is connected via the USB port does work.

I have a 13" Macbook that, all of a sudden, cannot find my HP 4280 printer on my network. The Printer is plugged into my 21" iMac, and I'm using a Linksys router. I never had any trouble until recently, and when I open up the "Printers and Faxes" option in System Preferences, my printer isn't listed. When I click "add a printer", it's not there. I have cleared my printers and reset everything, but it hasn't fixed it. I can plug it in via USB and it recognizes it, but it won't find it via airport.

Just wondering why does apple supply firewire ports on all their comps including laptops, because these days I can't find anything that has firewire ports that I will use everyday i.e. flash disc, HD, mouse etc. I know there's somewhere a 2.5" HD firewire case available but I already have a USB case for an external, and it would probably be more expensive to get it. What do you guys use firewire ports for?

I have a 15" MBP and am now having trouble discovering my printer on it. I have the printer connected to my iomega powered hard drive which in turn connects to my MBP via firewire 800. Earlier the printer was working fine when the iomega was connected via a USB port. BUt im short on USB ports (one goes to my Companion 5 speakers and the second to a 2nd display besides the mini DVI display) hence need to connect via firewire.

About to take the plunge and buy my first laptop (currently have a G5 PPC imac.) I'm planning on using Logic 9, Garageband and Sibelius, and recording live instruments. It will be my main computer, and will be moved about a fair bit. I'm going for a Macbook Pro since Apple decided to remove the Firewire ports from the Macbooks. Any thoughts on minimum spec? I can't decide whether to go for 13" or 15" - and would appreciate any ideas on what extras are really worth the additional cash (I haven't got an unlimited budget.)

I am not a huge Mac guy, but have to use them at work? Our Mac Pro lacks enough firewire ports for the configuration I need to do. So I guess I need to get a firewire 800 card and it will only be used in conjunction with out AJA unit (HD video production), so if it has one or four ports it doesn't really matter. Anyone have a brand or specific card they prefer?

I've been thinking about getting a Harddrive Dock. I had a Seagate External USB 2.0 drive but in windows, I didn't get more than 40MB/s which is slow. The Macbook Pro's have Firewire 800 which I think is significantly faster than USB 2.0. I also found some HD docks with firewire ports. So, what kind of speeds can I expect with firewire ports? On another note, I wish the macbook pro had an esata port!

I have a new iMac and an older MacBook. I wanna transfer about 70 gigs of info to the macbook from the iMac. Only problem is the iMac has a newer firewire port and the macbook has an older firewire port. Transferring wirelessly through aim will take way too long. Can I connect through the ethernet ports or maybe usb ports?

I'm wanting to connect my DV Camera and an External Firewire HDD to my mini. I really only need two firewire ports: one for the camera and one to daisychain any further Firewire HDD. This is all in aid of being able to digitize HD Tape footage with the mini using FCP so I can do all the editing etc of the Mac Pro. I've found a few online such as:The Belkin Firewire 6 Port Hub, Belkin Hi-Speed USB 2.0 and Firewire 6 Port Hub and the 1Lynx 800 Advanced Firewire Hub (99MO018202).The stackable Belkins look great

If I connect my Western Digital 500 GB external hard drive up to a computer using the USB port, then can I daisy chain a firewire camcorder to the hard drive and use it with the computer? Or is that impossible?
I hate the fact that the Macbooks don't have firewire, other then the white one. or the Pros.

I have a 2006 Mac Pro and recently my firewire ports stopped working (front and back). I did a little searching around found a suggestion to try resetting the Mac's PRAM and NVRAM by holding the Cmd-Option-P-R keys down while booting. I have tried this numerous times and it doesn't seem to do anything (i.e. the Mac just loads OS X and doesn't re-boot like the instructions say). I'm using a MS Wireless Comfort Keyboard for Mac. Can you reset using a wireless keyboard?
Since I wasn't making any progress with that, I was toying with bringing in the Mac to a genius bar. Never having used the genius bar before - how does it work? Do I bring the computer in and leave it with them? Do they work on it while I'm there? I don't have an extended warranty so do they charge time and materials? I'm wondering if that might get awfully expensive and if I ought to just buy a PCI-X firewire card instead.
Any suggestions?

I bought a powermac G4 from ebay awhile back but just recently got it up and running. So far i am liking it and decided i wanted more ram then the 384MB it was sent with. So i looked on ebay to find ram, i purchased this ram right here. [URL] I bought 3x512mb and none of the sticks are recognized in any of the 3 slots. I'm thinking the problem is that the ram is high density, can any give me their opinion on it. Also, with pc's there is a way to get to a bios screen, do macs have anything similar to that? Besides the boot selection screen? I forgot to mention, the mac i own is a powermac g4 single 533MHz cpu.

would it be possible to solder any wires to get power onto the USB ports on a G3 iMac? I have a blue 500Mhz model, if that would make any difference. the reason that I want to do this is because all of the iPods use USB now, and I would like to be able to charge mine while I am syncing it.

I've already RMA'd the first 1gb stick back to Crucial, and now I'm on the second. Sometimes the system boots, sometimes it hangs at a blank screen until I hold the power button down long enough to turn it off. But when I CAN actually get up and running, "About This Mac" reports that I only have the onboard 512mb. System Profiler says my singular expansion slot as empty! Yes, I've tried re-seating it-- many times. To no avail. I'm also positive the module is as far into the slot as it can go. And I find it hard to believe that Crucial would send me two faulty sticks in a row. Unfortunately, due to my built-in 512mb, I can't boot off the Crucial ram alone.

I pulled a 256mb stick out of the girlfriend's dead PC laptop and it fits in my 14" iBook G4 and when I originally put it in, "About this Mac" said I had 768mb, meaning it recognized the new RAM, now its about three weeks later and "About this Mac" says its 512mb again. So, I pulled the RAM out, put it back in, it recognized it for about a day and now its back to saying 512mb.I know when you buy RAM new, it comes with a CD(usually) to scan your computer, so is that the problem and if so, is there a download of the software online?

When I installed it, system profiler keeps saying it's 256. I have a 128 and 2 64's in there. In the 4th slot I put the 512. I tried just putting it in (to make just 512) and it still said.
What is weird is that when it only had the 512 stick in there, it seemed faster then with just the other 3 sticks. Is it just saying the wrong number?

I just replaced the original 20gb Toshiba HD in my 12" white G4 iBook (1.2gHz, 1.25gb RAM) with a new Western Digital 80gb Scorpio drive. No real issues with the swap, except the new harddrive apparently isn't being recognized. Don't see it in either the Disk Utility or System Profiler, but I can sure hear it spinning after power-up. I know it needs to be formatted, but how is that possible without being able to access it with the Disk Utility?
So, what's my next step? Anything I can try without taking the whole damn thing apart again and checking things with the old harddrive? BTW, only trouble with the old drive was its size. I've been running Leopard on it for several months.

I have two USB harddrives and neither of them are recognized by my G4. One of them consistently requires two ports for power, so I'm not surprised that one isn't working. However, my backup drive (a Verbatim) should not need that and it is supposedly compatible with USB 1.1 ports. It shows up on a Macbook. I am also quite sure that the ports themselves are working.

I have an iBook G3 Dual USB with 256MB of RAM currently (128 on LB, and 128 in the user accessible slot under the keyboard). I bought a 512MB chip on eBay that meets the exact specs of the required RAM (512MB PC133 SDRAM SODIMM 3.3V) but when I insert it into the RAM slot and turn on the iBook, it says in About This Mac that I only have 128MB of RAM. what I can do, or is the chip possibly not compatible with Apple?
