Another Firewire Power thread

can I get an official statement of "will or wont work" on buying a bus powered firewire audio interface for my macbook pro? In single user start up it says the chipset is a ti 8025. I was hoping to either buy the motu traveller or something similar. I've read all sorts of hubub about apples chipsets not providing enough power.
Can it really be true that I can't bring my computer to the field and record some audio with professional microphoes?

The threads I've read about bus power inadequacies relate to usb where there is a definite limit on power supplied - 500mA. No doubt there is some limit on Firewire too but all the comments I've read are that it is very adequate.
If you want Apple feedback you might try phone support, the local Apple dealer or the Contact Us at the bottom of these pages.

Yet another grey folder thread, help!

Sorry for yet another grey folder thread, but here goes:
Today, earlier, installed Firefox update, along with some addon updates for that program. Quit Firefox and attempt to relaunch, relaunch fails. Reset computer, thinking that will do the trick, I now have grey folder with question mark.
Resolve attempts: reset pram = fail; apple care cd = will not launch/fail; disk utility from original install disks = fail; cannot get repair of disk or permissions to work, continually get error about "failing on exit"; safe mode launch = fail
So, I've done everything, and I've come to conclusion that I am f***, and my HDD is fried (but I hope I am wrong).
So, dear gurus, my question(s)
A) Is my HDD salvageable at all? is there some trick to getting the AppleCare cd to work? Anything?!?!
if not, then B) How can I recover my documents/music/pictures? Long story short, there are several things on there that never had a chance to make my back up schedule, and I desperately want to keep them. Any way to make/copy a disk image to save the docs/imgs, or Firewire them to an external hdd? Do I need to consider a professional HDD rescue?

Looks like a mechanical failure, and Apple won't cover the replacement due to a drop it sustained a year or two ago (the power cable was in, and it fell on the connection point, denting that in, Apple states there is a critical board their and that it would be $950 Tier 3 repair which I can't afford). So I'm going to try a Firewire Migration and a few other things and see if that works. If not, oh well. Thanks everyone for the ideas!

IPod mini can't see firewire power adapter after 1.4.1 update

I updated my mini to the (infamous) 1.4.1 update, and now my firewire connection doesn't appear to work. When plugged into the computer with the firewire cable, mini doesn't appear on desktop or in iTunes, though it will start recharging the battery. When firewire power adapter is plugged into dock or into mini to try to recharge, it doesn't work. I purchased a new firewire cable & adapter but it's behaving the same way. USB cable to computer works fine (mini shows up on desktop and in iTunes). I've tried the Reset, Retry Restart, Reinstall, Restore. protocol several times with no success. I've tried Resetting the mini while plugged into the firewire power adapter. No luck.
Any suggestions?
Is there a way to uninstall this update?

Thanks Chris - I did this, and am now running the earlier version of the software, but my iPod still can't see my power adapter. Any ideas about this?

Can I charge my new ipod using firewire power adapter?

Just got my new 30GB ipod and realised that it doesn't come with power adapter to plug in directly in power outlet.
Can I use the firewire power adapter which I have leftover after my 3rd gen ipod died on me?
Also can I use the firewire to connect it to my powerbook for charging and song transfer? I thought firewire is faster than usb2 then why new ipods don't come with firewire cable anymore?
Many thanks.
PowerBook G4 Mac OS X (10.4.5)

think if you do your research and read up you will see the USB2 is indeed faster than Firewire. I actually did a few test on a dual G5 using both the Firewire and USB2 and in all my test, USB2 was faster.
If USB2 was faster for you, that's wonderful. I'm not about to start arguing with you over it.
What I can tell you is that you're certainly in the minority if this was the case for you.
USB2 has a theoretical maximum speed of 480Mbps. While this is certainly a higher number than Firewire 400's 400Mbps, Firewire will still vastly outperform USB2 in almost every case. It is near impossible to get anywhere close to 480Mbps with USB2. Even under ideal conditions, USB2 still has to contend with other processes on the machine, and other devices in the bus.
This is the nature of USB's design.
It is not uncommon for Firewire to reach near maximum speeds consistently. This has been proven time and time again.
Like I mentioned already, if USB2 is faster for you... go ahead and use it. I'm not going to tell you otherwise.
I'm quite sure I've done sufficient research on this, as well as many other people in this industry, and these forums. Perhaps it is you that might want to do a little more reading.

Apple FireWire Power Adapter and iPod Classic

I just looked through the user guide, and it doesn't mention anything positive or negative about using the Apple FireWire Power Adapter that came with my 3G iPod. Any chance I'm going to fry my new iPod if I try charging it with the Firewire Power Adapter?
Thanks,
Steve

No, you will not fry your new iPod.

Will USA Apple Firewire power adapter cope with 240 volts?

Hi, just bought an Apple OEM firewire power adapter, see here
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330275832822&ssPageName=ADME: B:EOIBSA:US:1123
Anyone know if this will this work without a voltage convertor in UK & Europe?
It's for an iPod mini.
I know one can charge by connecting to computer but it's more convenient to plug into the wall.
Thanks for any help.

Oh yes, thankyou for clarifying my mind on that.
I also bought a syncing firewire cable from the same place while I was at it so she should just need one cable then to do both charging & syncing as long as the firewire works abroad.
I'll inspect it when it comes & if in doubt we could leave the firewire power adaptor here for when she's in US & get a USB power adapter in UK for there & Europe.
Or I could sell the firewire power adapter to keep things simple.
Thanks a lot Chris.
In case anyone has any experience using the firewire power adapter abroad I'd be interested.
Thanks.

Is it possible to use the firewire power adapter for ipod to charge an Ipad

There is information everywhere that the Ipad doesn't charge with low power adapters.
The first power adapter I received with my first Ipod was the firewire power adapter and it allows intensities even higher than the 10 W Ipad adapter.
Could this old adapter be used with Ipad
Model n. A1070 output 12V 6.7 A if I believe what is written on it.

You should only use a USB-type charger for the ipad. Any other charger is risking damage to the ipad.
The ipad uses 5Volts at 2 amps for best charging. This is why it came with the wall charger.
You can charge it with any 5 Volt USB charger as long as the output amps is approximately 1 amp or more. If the amps rating on the charger is less than 2 amps, it will charge slower, but it is safe. The ipad will only draw the current it requires, but any voltage higher than 5 volts is risking damage to the ipad.
Hope this helps.

Ipod mini´s FireWire Power Adapter

Hola,
I was wondering if I could use my Ipod mini´s FireWire Power Adapter to charge my new 5G Ipod?
I guess there´s been alot of similar questions, but I´d be very happy if someone could help once more.

Yes, you can use that adapter to charge the 5G iPod.

Can the iPod firewire power adapter(LR56612 A1003, using 12V pin

Can the iPod firewire power adapter, part# LR56612 A1003, using 12V @ 1amp on evil connector pin#19.20 to charge iPad2? I am trying to save a few bucks and make my 31+ years of Apple life easier. Thanks a bunch.

Firewire power??? what is that?

i've heard of it but i don't know what it is....

FireWire is the Apple brand name for the IEEE 1394 interface. It's a way of connecting devices to your computer, something like the USB you'd be more familiar with. Firewire power presumably refers to the power going to a Firewire port: Wikipedia - Firewire

Not enough FireWire Power?

Hello,
on my new MPP17 C2D I noticed a dramatic change in the behaviourof the FireWire ports. It seems that less power is provided over both FireWire ports than on other/older MacBooks.
Example: I have an external WiebeTech FireWire hard drive that works without an external power supply on all older PowerBooks and even on my MacBook CD. It does not work on my brand new MBP17 C2D. It tries to power up the hard drive for 1 second or so, then stops, then tries again etc.
Is ist true that the FireWire specs on the MBP17 C2D have changed, or is someting wrong wit my MacBook?
Any help is greatly appreciated.

MBP17 C2D Mac OS X (10.4.8) 3GB/200GB

Howdy!
I'm looking at the same possible problem. I have not purchased a bus powered external hard drive, yet. I have MBP 17 core duo, not the new core 2 duo.
I've looked at http://www.wiebetech.com/products/ComboGB.php
AC adapter optional
Most FireWire and USB ports provide enough juice to power ComboGB, so most users prefer to use ComboGB without an AC adapter for maximum portability. For users who prefer an AC adapter or who must use one with their computer, an AC adapter is available separately.
You will need an AC adapter (or use the included USB power cable) if the port you are plugging into does not provide enough power for ComboGB. This includes all 4 pin FireWire hosts (such as Sony iLink which provides no power at all) and some USB ports.
In most situations, the provided USB power cable can power the drive and pass data at the same time. Alternately, the USB power cable can be used for power only so you may use the USB cable for power and still use a FireWire cable for data.
For yet another configuration option, WiebeTech's Cable-32 is a smaller USB power cable (with no USB pass through) and is an optional power cable for ComboGB.
This setup, with USB power and Firewire data transfer, is interesting. But my research has not 100% comfirmed this option. However, it seems that the external hard drive needs to be a Hitachi drive.

ALTERNATE STORAGE EXPANSION OPTIONS
If you want to further expand storage on your MacBook Pro, a cool way to do it is with a bus powered FireWire 800 enclosure with a SATA notebook drive inside. (If you go pure SATA enclosure or use the USB 2 port, you'll have to have an AC adapter.) Check with Wiebetech, TransIntl, and OWC for bus powered FW800 notebook enclosures that accept SATA notebook drives.
I wanted to bring this to your attention and I look forward to your comments.

Another Magnetic Case Thread

So, I see that several people have asked about the cases with magnets causing problems. The resounding answer seems to be no, so I'm looking for some theories on what might be going on with my touch. I got a leather case that has two magnets on the side to keep it closed, instead of the bottom (as most of the threads seem to deal with). I put my touch in there and a few hours later, it wouldn't come on. I had to reset or whatever they call it when you hold down both the power and home buttons. This happened several times. I charged it, did all the "r"s except a complete restore and it seemed to be ok. That was late at night, so I only tested it for a few minutes, then went to bed. The next morning (this past Tuesday), I was trying to use it and kept having similar problems, only now I would sometimes just get a white screen. I took the case off and left it off. It is now late Wednesday night. I have had my touch out of the case with the magnet for about a day and a half and I haven't had one problem. I didn't do anymore resetting, restoring, etc. It just started functioning normally again. I plan to test the case again tomorrow, but wonder if there are any thoughts on what might have happened. I wondered if maybe the magnet near the WiFi was causing problems in it which was affecting my touch. So, thanks for the input and I'll make a note when I finally get it back in the magnetic case!

AAPL, I saw your response in another thread speaking of how you showed people at college things that magnets did not mess up, but supposedly were supposed to, such as floppy disks, etc. Based on that, I was hoping that you would catch this thread and offer some insight. I'm afraid that I still believe that the magnets are the trouble makers. I know that on the DLO case, the magnets are at the bottom. My case is not the same. The magnets are on the left side at the top and bottom. In addition to my husband putting the case and having the exact same problem, I tried it again. After seeing your response, I put the case back on. FIVE minutes later, I had the exact same problems. iPod wouldn't come on. When it did, I had a flickering screen, then the Apple. I haven't had any trouble with my touch since I took it out of the case Tuesday morning. Now, on Thursday morning, I tried the case again, and voila! Problems. And as soon as I took it out of the case and restarted it, it began functioning as normal. How do you explain that? (That isn't supposed to sound smart alec, but truly curious!) The rest of the case is just leather. I know that isn't causing problems. To me, it is obviously something about the case, so I think that it must be the magnets. Thanks!

Can i use my old ipod firewire power brick to charge my iphone?

i have a power brick from an old 20g b&w ipod. it looks like a laptop brick, but smaller. it has a FW socket and says it puts out 12v 67a.
i'm going on a trip and would like a spare charger. will this work for my iphone 3g or will it fry it?
thanks!
btw - i did a search on this topic and found similar threads, but none addressed this particular FW charger.

i'm getting a 404 error on that link for the ipod touch manual. but i looked at p.33 of the iphone user's guide, and it does say that you can't use a FW charger. it doesn't say why, however.
i see that the iphone charger is 5w/1a. what happens if you use a 12w/67a charger with a device that's configured for the former?
according to somebody in this thread, the device being powered "requests" only the power it needs, so you can use a more powerful charger (a MBP charger for a MB, for example) - but you can't use a less powerful charger to charge a device that needs more power (a MB charger for a MBP, for example).
(for instance, can you charge a macbook with a macbook pro brick - i know you can't do the reverse)

IPod Firewire power adapter??

Hi I'm getting a Touch next week (actually somebody already bought it for me but its coming with it next week) and I have a 2nd (YES, SECOND) generation iPod with 15gb...
They didn't come with a usb cable back in those days, there was only firewire 400... but i bought that firewire to usb cable from apple back then that had 3 ends, the dock connector, a firewire 400 and a usb 2.0.
Here some pics to help
http://flickr.com/photos/filipeg165/1480542072/
http://flickr.com/photos/filipeg165/1480542704/in/photostream/
The question is: can I use this power adapter with my new touch? it is not a usb power adapter, it is a firewire one because the port ON the connector is firewire.
ps: yes I managed to make my SECOND (lol) generation iPod survive all these 5 years... and it still works
Message was edited by: filipeg165

to answer your qeustion YES. i had purchased the third generation ipod the one with the four buttons on top of the menu with the button in the middle was just touch... it lit up red on the buttons... but that was when they used firewire and jsut kept that with the ipod and i rmemberd how mad i was because i had windows and had to wait another week after christmas for my usb cord... but back then APPLE INCLUDED THE POWER ADAPTER working with the firewire cord obviously... but i wanted a way to charge my new ipod touch away from my macbook...
so i plugged it in to the firewire charger all the way back from like 03 or 04 i cant remember i think 03... but anyway yes that firewire charger does work with the touch

Can anyone help?? Another new MacPro thread....

Hi all.
Another person here having big issues with PP CC 2014 on the new MacPro..
A little background;
I've been having issues with PP for years. Previously I was a photographer, and Lightroom was my software of choice. That was a great Adobe experience, pretty faultless software really...
Then when I moved to video it was a different story... obviously it's a whole different ballgame dealing with video files, I've not had much luck with my editing workflow!
I was working off an underpowered PC first, then was on a few Macbook Pros. Eventually, I got the go ahead to get a new MacPro from my employer, I thought that would solve all my problems! How wrong I was!
Even after the apparent "fix" for the GPU issues, I'm still having problems...
I'm no Adobe basher....No one wants PP to work well more than me (Al Mooney got highly offended on Twitter after I suggested PP might be slightly less than perfect!)
I'm hoping I might get some tips to improve performance or even a fix for the issues I'm having.
Here's the gist of my specs, can give more if needed;
Yosemite 10.10.2 (14C109)
Mac Pro (Late 2013)
3.5 GHz 6-Core Intel Xeon E5
64 GB 1866 MHz DDR3 ECC
AMD FirePro D700 6144 MB
My main drive is a G RAID 8GB TB2
So,
My main issue is that when a sequence gets more complex, the performance dips massively, to the point where it's unusable and crashes constantly.
The timeline freezes, the playhead is laggy, the system gets really slow to respond in general..... Maybe 15 seconds for the keyboard to respond to keypresses. (or else I need to tap spacebar twice instead of once to get it to respond). If I try to make any change on the timeline that anything more than a simple delete etc, the system can freeze and I need to force quit.
Another symptom is that when quitting the program, often it doesn't quit properly and I need to force quit.
The sequences I'm working on don't seem that demanding (especially give the machine I have) so it's really confusing as to what the issue is.
We're talking videos usually in the 2 -5 minutes range. Maybe 4 video layers. Footage wise; generally 1080p XAVC from a Sony F5, some Canon 4K from a 1DC. Can PP really handle native footage, should I be transcoding??? One of the big benefits of PP is the apparent ability to handle native formats, so it's really disappointing if that's the issue....
I do use a reasonable amount of plugins, like Izotope for denoising dialogue, the dreaded Red Giant plugins, and occasionally Red Giant Denoiser (is this the root of my problems??!). My current project has two layers keyed interviews (2 angles) and I'm using Ultrakey for that. (I bought Red Giant Primatte Keyer, but my system isn't powerful enough to run it without major issues....ridiculous!!)
If anyone has any suggestions I'd love to hear them. I've read other threads but my issue seems different. I can't rule out that I'm making some obvious mistake in my workflow either... so any general workflow best practise tips in that regard would be good too.
Sorry for the long thread and thanks for reading.

Hi healyb2,
Sorry you're experiencing this issue.
I think I've identified one of the issues, Izotope 4 Dialogue Denoiser.....
I've disabled it on an existing sequence and the crashes have stopped (for now).
Let us know if these issues crop up again. You can let us know directly here: http://adobe.ly/ReportBug
So, possibly (like Red Giant) Izotope plugins may not work usably in Premiere Pro....... which really grinds my gears......
Actually, we work hand in hand with plug-ins developers in the realm of compatibility. Some of these plug-ins companies are quite small so you have to pay close attention to precisely what is supported for the host application. In some cases, it takes some time to catch up to the latest versions.
why are Adobe not calling out the plugins as not usable? What about the plugin manufacturers themselves? I can't see this being a performance issue on my end...frustrating!
That's actually up to the plug-ins manufacturers. Please communicate with them accordingly regarding compatibility. Sorry for any confusion this may have brought about.
Thanks,
Kevin
