Troubleshooting Firewire

My Firewire does not appear to be working, Firewire drives (myBook) won't mount via Firewire, but they will mount via USB. When I check the system (more info from About this Mac) and click on the Firewire option I only get: "Firewire Bus:"
Any ideas on trouble-shooting/restoring firewire
Thanks,
Eric

I've read the FAQ's and I still have problems. Would anyone be able to assist? Thanks....
I have the following:
Power Mac G4 Mac OS X 10.3.9 (7W98)
CPU Type: PowerPC G4 (2.9)
Number Of CPUs: 2
CPU Speed: 500 MHz
L2 Cache (per CPU): 1 MB
Memory: 1.25 GB
Bus Speed: 100 MHz
Boot ROM Version: 4.2.8f1
Serial Number: XB04906TK86
My APS tech external CD/DVD player/burner was working fine up until a couple of weeks ago. Now my firewire ports do not show up and using any firewire device is not possible.
I accomplished all of the suggested fixes in Article: 88338: “What to do if your computer won't recognize a FireWire or USB device” Last Modified on: July 26, 2007 to no avail.
I reviewed http://www.macfixit.com/article.php?story=20041221081432908
and followed the suggestions to no avail.
I’ve read the fixes in FAQs to no avail:
unplugging all devices to include USBs disconnecting all FW devices, shut down the Mac and unplugged it from AC power (wall socket) for 30 minutes, plugged it back in and tried FW,
reinstalling OS software, using disc utility after installs with Repair Permissions in Disk Utility before and after the update reconnecting all devices one by one,
Zapped 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.
Firewire ports still do not appear under the system profiler.
I haven't attempted to replace the internal 3.6v lithium internal battery as was suggested in one of the comments. I could not find the battery anywhere in town at radio shack or any of the computer stores. Is the battery apple proprietary? Would not having the battery installed ( as is the case now ) affect the system from recognizing the firewire ports or is my problem bigger than that? What is the function of the battery and what functionality does it affect?

What's the best way to troubleshoot firewire?

I have a 2TB Hitachi Deskstar in a Rosewill RX81-MP-SC-SLV External Enclosure (Oxford SATA to FireWire chipset) connected to a MBP (late 2008) via FireWire 800 cable, which is used to store recorded video from an EyeTV Hybrid 2009 tuner via EyeTV 3.5.2. Recently, I started experiencing problems where OS X 10.6.7 would put up a warning that the external hard disk had been improperly disconnected. I thought the connection might have been loose, so I reseated it, but the problem recurred. There have also been problems recently where only 25 minutes were recorded of a session of Saturday Night Live. Disk Utility verification shows nothing wrong (the FW connection lasted long enough for it to run). I've tried swapping the FW 800 cable, but the problem recurs.
So the problem could be:
1) The 2 TB Hitachi hard disk
2) The Rosewill enclosure
3) The FW 800 port on the MacBook Pro
My guess is that 2) is at fault, but how can I isolate the problem at this point? I do have some other external hard disks with FW 800 ports.

It is about $330 and you can do some editing, chapters as well. My brother has it and used the 'one-touch' method to copy his old tapes of some boxing matches. I read the manual on-line.

Troubleshooting FireWire - Known Good Device, Cable, Mac

I'm having a bit of an odd issue. I'm trying to connect my Scientific Atlanta Explorer 8300HD (DVR) to my Mac Mini (mid-2010). The device isn't detected, which doesn't seem so odd, but here's where the trouble starts:
* I know it's not the DVR: It connects to my Macbook Pro (mid-2010) just fine.
* I know it's not the cable: I have two FireWire cables, both of which can connect the DVR to the Macbook Pro without an issue.
* I know it's not the Mac Mini: It can detect other FireWire devices, and I've taken it into the Apple Store and confirmed that the logic board is in proper working order.
Things I've tried:
* I've reinstalled OS X Lion as a clean install; the DVR still wasn't detected.
* I've removed all other peripherals; the DVR still wasn't detected.
I'm wondering if there might be relevant differences between the MacBook Pro and the Mac Mini that could cause the DVR not to be detected on the Mac Mini, even though all of the individual components work in other permutations? Really, I'm just baffled, so any advice would be appreciated.

The Mac Mini shows only the bus:

Need firewire cable information

I need to purchase a Firewire cable compatible with an iMac PPC and iMac Intel in order to migrate user account from old iMac to new iMac. Is there a special cable for this? My local electronics store has straight thru firewire from 400 to 800 they are not sure that is exactly what I need.

See this How to use and troubleshoot FireWire target disk mode
If the connectors on the cable match your two Mac's and the cable is FireWire it will work. Just check the above link to make sure your older system will work with target disk mode (it should but just to be on the safe side).

Target computer not appearing on host computer during Firewire Target Disk Mode

My 2009 iMac recently started getting stuck on the white Apple loading screen and disk utility said it has an error that it can't repair. I asked a question on here about this and was told I can back up my iMac files on my Macbook Pro using a Firewire cable.
I bought a 9-pin to 9-pin Firewire cable and have been trying to use Target Disk Mode to connect my two computers but my iMac is not showing up on my Macbook Pro anywhere (desktop, finder).
Here is how I have been told to do this: 1. Connect the two computers with the FW cable. 2. Boot the iMac and hold down T to boot into TDM. 3. Boot up the Macbook Pro and I should see the iMac HD on my Macbook Pro
I have also tried connecting the FW cable after I boot the iMac into TDM (I read somewhere that this works also) and my iMac HD still doesn't show up on my Macbook Pro.
Am I doing something wrong? Please help me with this!
(I wasn't sure which community this issue belongs to so I'm sorry if this is the wrong place for my question!)

Disk Utility says "drive can't be repaired, disk and restore your backed up files."

My Mac Book Pro froze yesterday and I had to force restart it. It had been showing me messages that my hard drive disk was full for a while and I was in the middle of transferring files to my external hard drive and I accidentally put a huge large file from my external hard drive into the trash on my laptop which makes me wonder if that means I added more GB to a computer that was already very full. Anyway, after freezing I restarted it and the desktop wouldn't load properly. The desktop picture was there, but folders on desktop did not appear, finder bar was missing and the dock was acting super slow and nothing worked when clicked on. Then the next few attempts were around the same result and eventually became stuck on the apple logo, spinning gear and a progress bar that was not loading at all.
Here's what I've tried so far:
Safe mode- nothing happens
Command + R - I am unsure how to work this since I can't seem to find an internet connection when it prompts for one. None of the internet connections have much signal and my own information doesn't seem to load since the gear spins to find the internet connection name and password I typed to load it but can't seem to find it. Perhaps I have the wrong internet information, but I don't think so.
I tried Command + S to use in single user mode and type in a command to help fix the drive, BUT, even though the black screen and white lettering mode did show up, it remained in a place where I was not allowed to type anything and the last thing written at the bottom of the screen was something about set up for bluetooth, I think. I tried this twice and both times it stopped in the same place and I could not type a command.
Disk Utility using installation dvd to verify and repair disk. Verify says disk needs repair and then repair has some red colored phrases: Invalid volume file count. (It should be 786374 instead of 786274) Incorrect number of thread records. And there was another problem listed but I do not remember it. Then, near the end of repairing it says: "Disk Utility stopped repairing Macintosh HD." It tells me it couldn't repair the disk and that I should back up as many of my files as possible, reformat the disk and restore backed up files.
That would be fine and dandy, but I have no idea how to back up my files and do all this. I have no idea how to exactly get the data off my hard drive. If someone does, please list a step by step guide for me on how to do so.
I have an external hard drive and I tried plugging in and selecting the hard drive and making a "New Image" to copy to the external hard drive destination, but it just stops a few seconds into it and tells me there is an input/output error. I tried read only, read/write only, compressed options for making a copy and all yield the same result.
In Disk Utility, I believe I have a partition -the Macintosh HD. I have listed on the left hand side: 320.07 GB Hitachi HTSS45.....etc. and below it in non-bolded, grey lettering it says "Macintosh HD."
The Hitachi, when clicked upon, shows the S.M.A.R.T. status as Verified and the Macintosh HD doesn't show much in details except for "Not mounted."
At one point, the Macintosh HD was in bold lettering and seemed to be mounted for a few minutes. When that happened, I was able to see the details reading: Mount Point: /Volumes/Macintosh HD, Capacity: 319.73 GB, Available: 11.92 GB, Used: 307.81 GB, etc.
I'm getting nervous to keep turning on and off the computer on force start and shut downs, especially since I have been reading up that the longer the computer is on, the more the hard drive is in use and the more chance for it to start deleting or overwriting my files. Is this true?
It's not mounted anymore since it was momentarily mounted. I just want to get my files off the disk and save them to my external hard drive. That is my main goal right now. What can I do?
Thank you in advance for your help!

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

How to backup files onto external hard drive if my MacBook's graphics card is broken?

Hello,
I have a 15" 2012 Macbook pro with 2gb of ram, i7 processor, and a 250 gb Hard drive. In the middle of using my computer, the screen went black. Upon rebooting the computer, I noticed gray and white horizontal lines running across the screen, but I was still able to see the apple logo and loading indicator in the background. As soon as the login screen appeared, the screen went black again.
Genius Bar Diagnosis:
A few days later I took my computer to the apple store to have them diagnose the computer to determine if the hard drive was corrupt or if it was just a display issue. They found that the hard drive was still functioning properly, so no information was lost. The problem was that the graphics card needed to be replaced. So they offered to ship my laptop to an Apple repair facility in Houston, Texas (nearest one to me) and replace the graphics card, as well as any other parts that seemed to be damaged, for a flat rate of about $315. They recommended that I back up my hard drive just in case they found an issue with it (despite nothing showing up in the diagnosis at the genius bar) because the technicians at the repair facility will just swap it out for a new one.
My dilemma:
The employee at the genius bar gave me a list of Apple Authorized Service Providers that could help transfer the data from my macbook's hard drive to an external hard drive. I got a quote from them for $150, plus I would have to pay for a new external hard drive because my other one is full. In an effort to save money, I want to see if there is a cheaper way for me to backup the hard drive by myself. I have a pc laptop that still works fine, so I have been using that since my MacBook Pro died on me. Is there any way I could use that other computer to somehow backup my macbook's hard drive? Or would I need another mac to do the transfer? I have looked into buying a hard drive sled, but I don't know how those work, and I may not have all of the right equipment for it. If that is something I have the right tools for, and it's cheaper after buying all the accessories, then I would much rather go that route than taking it in to get serviced at an AASP store. Please help!
I'll give good ratings to those who give me useful advice.
Thanks,
Matt

Hello mafrerichs and welcome to Apple Support Communities,
Simplest way is to use Target Disk mode:

You could also pull the drive out of your MBP and use an external USB case or SATA - USB dongle to hook it to another Mac.

My macbook pro wont start up

goes to a gray screen with apple logo and just the gear spins non stop, never made a recovery disk.did a control r and got to the disk utility but still wont work on repair, id like to try to save my data. any ideas...running lion os not sure i remeber what version

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

How do I transfer all my music, apps contacts etc for my iPad and iPhone to my new laptop from a desktop?

I can't update the software on my desktop because it's too old and no stores seem to have the "bridge" disc I need to upgrade my current system. So, I need to transfer my synch abilities for my iPad and iPhone from my desktop to my newer, more up-to-date laptop. What is the best way to do this? I have the apple base station also.

Post-Kernel Panic: Various questions on iTunes, mail, stability, help!

I recently experienced a Kernel Panic on my Macbook Pro from late 2010 (2.53 ghz, 4 gb ram, 500 gb OS X snow leopard etc).
First, a quick overview of the Kernel Panic process:
I had a lot of stuff running simultaneously, and the system started hanging for several minutes. I then made a manual shutdown by pressing the power button, and when I started it up again, I entered the wonderful realm of Kernel Panic.
Extended hardware test found nothing wrong.
Disk Utility told me there were a corrupt sibling file, as well as about three corrupt record files (I think they were called that - it looked pretty generic, but unfortunately I didn't write anything down).
I couldn't start in safe mode, a PRAM boot didn't do anything, nothing worked. I couldn't reinstall OS X, as I got a message saying there couldn't be written to my harddisk.
I didn't have any Time Machine backup, so a very friendly collague of mine took my MPB apart, and in short transferred the contents of my harddisk onto an external harddisk. I then formatted my harddrive, reinstalled OS X, and am now in the process of putting everything back in place, as well as I can. But I have a bunch of questions and observations I'm a little worried about, and I very much hope someone can help me.
It must be mentioned that I haven't taken the MBP online again yet; I am currently still at work and am not able to get my Mac online on the work network (it's locked). Therefore there are some OS X updates I haven't reinstalled yet.
- I have managed to rebuild all my subfolders in the default Mail program; however, my Inbox is nowhere to be found on the external harddrive, and I can't seem to find the location of my new inbox anywhere. Is it eternally lost, or can I restore it? My extemely important mails are saved (software licenses etc), but there were quite a few mails in my inbox that are important as well and i'd like to get them back.
- ITunes seem to have some issues with handling the import of my entire music/podcast archive (about 120 GB). If I select more than approx. 15 gb to import, it starts hanging, and I have to force quit it and retry with a smaller chunk. Is this normal, or should I be worried?
Note: I did notice that a couple of the folders in the salvaged iTunes archive were completely empty - there's only a picture of a blank piece of paper next to it, instead of a folder icon, and the size is 0 kb. I can just re-rip the music to my library, but I am a little suspicious of this.
- More iTunes. One of the times I force-quit it and then tried to reopen it, I got an error message saying that I couldn't open the iTunes application, because the files were locked, or the archives were locked, or something along those lines. I got quite a scare, but after restarting the mac, iTunes opened as it should. Again, should I be worried? Is this normal?
- I am considering getting a new harddisk for the MBP, a Seagate Momentus XT 500 gb, as I am a little wary of the default harddisk after this. I figure that since I haven't put anything back in place yet, it would be the same if I had to format and reinstall OS X once more. The damage has already been done, so to speak. Would this be a good idea, or is it unneccessary? (I have ordered a RAM upgrade, so i'll be running with 8gb instead of the default 4).
- Why did this Kernel Panic happen? I know I made a force shutdown, but why did it go so wrong? I would like to know what caused it, so I can prevent it. Couldn't it handle the extensive simultaneous processes I was putting it through (my gargantuan iTunes library was running, I was watching a video, had many tabs open in Chrome, it was hot etc)? Will the planned RAM upgrade fix the issue? Is there something fishy about my harddrive?
I hope someone will take the time to answer my many questions, and I am very grateful for any help.

The most important thing for you to learn from the experience is that you'll inevitably lose all your data if you don't make backups. Regard that as a certainty, not a risk. Do no more work with the computer until you have a backup solution in place.
The second point is that your hard drive has failed and you shouldn't continue to use it. Shut down the computer now and don't start it again until the drive has been replaced.
For future reference, familiarize yourself with FireWire target mode:
How to use and troubleshoot FireWire target disk mode
This mode can be used to access the internal storage device of a Mac without booting it.
Some of your files have apparently been lost or corrupted. If you don't have backups, they're almost certainly gone forever. It's possible to attempt data recovery on a failed drive, but the more you use it, the less the chance of success. I have no experience in this area.
As for why the kernel panic happened, that's impossible to say without a panic log, but it was most likely caused by the drive failure.

MBP stuck on grey screen

This morning my MBP, mod 6,2 (8GB, 500GB), started acting strange (would not minimize Word, Safari would crash and re-crash on restart...)
so I decided to reboot it. Never came back.
The system sits on the grey screen forever. In many attempts, once or twice it went to the login screen, and after I entered the password, got stuck on that screen removing the cursor.
So far I have:
- booted ML in recovery mode, checked and rechecked the HD (verify disk, check permissions....) - all ok
(recovery mode runs fine, I can browse the web, run disk utility....without any problem)
- reset PRAM and SMC (even if the problem does not appear related)
- booted the AHT disk and passed the brief test (am running the extended one now)
- booted in verbose mode and learned that the system gets stuck in these steps
Com.apple.launchd          1 com.apple.UserEventAgent-LoginWindow                       #          stopping job

where # is the process ID, which keeps increasing. The first time it appears, reads 249, then works its way up constantly.
Any clue on what could be wrong?? I'm mostly interested in backing up the last few days of work before doing anything
drastic with the system, but need to get in the system to do that.
Thanks in advance

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
