10.4.7 no more external Firewire HD

Hi,
I udated today to 10.4.7 and I can't see anymore my external HD (Maxtor 300GB) connected to Firewire. Any item isn't recognized or mounted through firewire (iPod, external DVD-RW). It worked perfectly until 10.4.6.
I tried to connect my external HD through USB 1.1 and it's immediately recognized and mounted.
So now I'm on big trouble as I have most of my data on my external HD but with USB connection it is too slow to open and work with big files.
I tried to update then from the 10.4.7 update combo but the problem remains. Off course it isn't possible to downgrade.
Any kind mind would have a 'trun around' solution until Apple would correct it ?
Many thanks in advance.
Best, C@

Unfortunately the "turn around" must be in place before the update is performed, usually in the form of a clone of the stable system to a second drive or partition. Then if the update is problematic, the system can be restored to the "last good configuration" by cloning the previous system back to the main boot drive. It would be cool if Apple built in a "revert" feature but since they don't, it's up to the individual user to cover his/her behind.

Cannot Boot from OSX on external firewire drive

I recently bought a seagate hardrive and installed it in an external firewire casing. I partitioned it into two partitions, and installed osx 10.4.10 on one of the partitions, the same as is running on my Ti Book.
I tried selecting the os on the firewire drive as the startup disk, but when i restart, after the grey screen i get the flashing question mark icon, until the mac recognises only the default osx on the internal drive and boots with that instead.
That not working, i created a clone of my startup disk using DejaVu in my system preferences and saved it on the other, empty partition on the external drive and tried booting from that.
On restarting, i get the grey screen once again as the backlight fires up, and nothing more. the screen remains grey without any further ado until i hold the power button and force it to turn off. then as i start it up again, up comes the flashing question mark icon followed by a boot from the internal drive.
Any Solutions on this?
Many Thanks, Neptune.

Hi Dale,
Whoops- everythings not as smooth as i thought it was!
since i restored my internal drive, a lot of things have been really messed up, starting with, for example, iTunes reverting to version 4 instead of 7. that wasnt a problem, i still had the 7 installer, and soon had my whole music library back again. but the computer appears to have a problem with the handling of graphics. the finder wont create previews of even simple jpeg images, nor will it for video. quicktime wont open any video file, i get some random error message which i cant remember stating it could not open the file. and if i view my finder window in grid icon view, the usual blue mac os desktop image that i keep as a background in the finder window isnt there, instead its pitch black. same goes for the slideshow feature in the application graphic converter, i can start a slideshow and it will scroll through the images, but every image will instead be completely black. there are no scroll bars in itunes. i can scroll down randomly by clicking where the scroll bar should be, but there is nothing visual there at all, no scroll bar, no arrows. when i connect my ipod, the main ipod window of itunes wont display any graphics either, be it the picture of the ipod or the capacity bar indicating usage of the drive for music, videos, data, etc. instead, fine print says something similar to 'cannot display image, quicktime and lzw tiff decompression plugin (?) required' I cant remember word for word what it says, dont quote me on that.
the computer also came to a dead freeze twice in ten minutes, i had to hold the power button down to get it to shut off.
im sure there are other issues too which i havent yet noticed, but even these, i havent the faintest clue what could be causing them!
do you?

Is it possible to detach an external firewire BOOT disk during sleep?

Hi,
I have an aging PowerBook G4 17 inch (3 years and 3 months) which is still good and fast enough for my needs. Last year the display and motherboard were changed which cost me some money so I would like to hold on to it for one or two more years. Yesterday I suddenly heard a strange noise coming from the hard disk and the Finder and Disk Utility ran extremely slow afterwards for some time. I shut it down, waited a couple of hours and now everything seems to be normal. I take it the hard disk might soon die (Toshiba make, more than 3 years old, a lot of graphics work requiring disk activity). Or 1° I replace the internal hard disk or 2) I buy an external firewire disk to boot from (which I can continue using afterwards if the laptop goes dead). I am leaning towards the second solution. However I would like to know:
1. Is it good behavior to put the computer to sleep, detach the hard disk (from which I booted) and attach it before waking it again? This would make it easy to transport it. I did a test and it seems to work however one test might not be conclusive...
2. Would my system be as fast as with an internal one (assuming I buy an external FireWire 800)?
Any feedback would be greatly appreciated!
Thanks!
PS: what is the average life of a PowerBook? The sales guy from a local Apple shop told me that after 4 years any Mac is good for the trash.

The sleep removal will work as long as the battery doesn't go flat but is not really good practice to remove a boot disk after startup.
Speed would be reasonable but internal would be better, replacing the internal drives on AlBooks is a bit fiddly but it can be done, see here for a guide.
The guy in the shop was trying to sell you a new Mac, there are people out there still using 10+ year old Macs!

External Firewire Hard Drive is not recognized

Hello
I have a LaCie External Firewire Hard Drive (like this one (http://www.lacie.com/us/support/support_manifest.htm?id=10105). Since it uses a fireware 400 cable, I bought a FireWire 800-400 adapter, the one from moshi that is sold in the mac store.
I have tried connecting it to both ports in the external harddrive, connecting and disconnecting and still is not recognized. Any idea and suggestions?
I already tried in another computer, with windows xp, and the hard drive works.
Thanks.

Hi, oops, I have more than 1 mac & I apologize for assuming you are a multiple mac owner..
You could visit your local Apple Store or Local Apple Approved Service Agent.
You could try connecting via USB if your external HD has the capability, it could also be a bad cable.
You can check the Finder -> Preferences & the Show These Items..
You can reboot with the Ext HD connected & see if it shows up on your d/top...L

HELP! - Error 1309 - Can't copy file over 10gig to External firewire drive.

I know this is more of a hardware issue but I know that only other final cut users would be copying single files over 10gigs.
I have a G5 that I use for video production. Video Files can be large and to back them up I got an external hard drive ( Maxtor 1-touch 200gig) When I try to copy a file on to it that is 10gigs it give me a 1309 error. I have found that other people have had trouble copying files over 2gigs over to an external firewire drive. But I haven't found any answers. Can anyone offer any advice on how to solve this?
Thanks

If you don't want to format it for the mac, you are limited to file sizes under 2gb.
Another alternative is to hook a firewire drive to your Mac and then share it with your windows machines (the program SHAREPOINTS is useful for this).
The drive can then be formatted Mac OS Extended and, once shared, the PCs can access all files without size limitations.
good luck.

Can't install OS 9 on external firewire disk

I am running Panther on an iMac G3 450. Some older software and games just don't run correctly in Classic mode, so I would like to install OS 9 on an external firewire drive. The original OS 9 disk from 2000 doesn't run with Panther. When booting from the OS 9 install disk, it can't read the firewire drive. How can I get the OS 9 boot disk to read the external drive for an install? Or - can I install OS 9 on my hard drive without affecting my OS X and all my software and files? Thanks.

Hi, sageimac -
The original OS 9 disk from 2000 doesn't run with Panther.
Correct. The installer on any stand-alone OS 9 Install CD, retail or original model-specific, will not run in OSX - it will run only when the Mac is booted to OS 9, such as to the OS on the CD.
When booting from the OS 9 install disk, it can't read the firewire drive.
The OS on OS 9 Install CDs contain the necessary software to 'see' a firewire drive connected to a native firewire port while booted to the CD, provided the drive does not need any additional software. If the firwire port was added via an upgrade card, OS 9 may not be able to see it without additional software.
When you added the firewire drive, did you reformat it using Disk Utility under OSX? If so, if the option to install OS 9 drivers was not selected, then that drive can not be mounted whenever the machine is booted to OS 9, such as to an OS 9 Install CD.
Article #106849 - Disk Is Available in Mac OS X But Not in Mac OS 9
Unfortunately, since in that case the drive probably did not have OS 9 drivers on it previously, there may be no solution but to re-initialize that drive - but it won't hurt to try re-installing OS 9 drivers while booted to the OS 9 Install CD, using Drive Setup's Update Driver function.
If it is necessary to re-initialize the drive, it can be done using Drive Setup while booted to the OS 9 Install CD, or by using Disk Utility while booted to OSX (be sure to select the option to install OS 9 drivers in this second case. This will erase it, so be sure to first back up your data. In either case select Mac OS Extended as the format.
Or - can I install OS 9 on my hard drive without affecting my OS X and all my software and files?
Yes - OS 9 and OSX are designed to co-exist on the same volume.
You should have no problem doing that, provided there is sufficient space on the hard drive. I do not consider my OS 9 to be overly fat; however, the System Folder still occupies about 0.4 to 0.5GB. OSX runs best when 5GB or so is left free on the drive. So, if you have 6GB or more free space on the internal drive, there should be no problem doing that.
Use the Clean Install method to install OS 9 from your original Software Install CD (not the Software Restore CD), or from a retail OS 9 Install CD of adequate version.
Note that a Clean Install of OS 9 removes nothing. It installs a brand new, 'clean' System Folder, renames any already existing one to Previous System Folder, installs a new set of standard OS 9 utilities if they're not already present, and little else.

Snow Leopard on external firewire hard drive keeps crashing/freezing

I own a 2006 iMac that came with OS X 10.4 Tiger installed and it has always been stable and reliable. Lately I had the need to use some software that only ran on OS X Snow Leopard so I installed an external Firewire (Western Digital) 260GB hard drive and put OS X Snow Leopard on it. For the first few months, everything ran fine, but as the drive slowly filled up (or perhaps with time), my Leopard external drive started giving problems, most commonly, it would lose its Ethernet connection for no reason, or I would get a line of black/multicoloured pixels appearing across my Firefox browser (or something else weird would happen to the display), followed by the rainbow wheel spinning indefinitely... this happened more and more often, when I opened too many applications at the same time, or more than 3-4 tabs in Firefox. Occasionally the screen would "white out" or go completely black. I'd have to physically switch the computer off and on again.
However, I still have not even used 20% of the hard disk space so its not a matter of the hard drive becoming full...
The Tiger internal drive is still running 100% fine so it's not a problem with my RAM...
I've tried verifying/repairing the disk, but it doesn't show any problems. Any ideas about what I should try doing next?
Thanks in advance for any pointers.
Message was edited by: artemisworks

Just so I understand this correctly:
1. Your internal hard drive is on Tiger?
2. Your external (a WD) is on Snow Leopard?
3. Where is the "partition"? Do you have either drive partitioned?
4. You only have the problems when you are booted from/working on something using the external drive?
I've seen quite a few posts here regarding problems with external Western Digital drives; it appears that their internal drives are fine, but the externals do not play nice with Macs after a while (maybe the enclosure they use??).
In any case, if your problems are only when using the Western Digital, I'd say return it if possible, get it replaced, or buy a different brand and use the WD as a not-often-needed extra backup.

10.4.7 update and external firewire problems with HD corrupion

Dear all,
Advised by Jpfresno I started this new topic about Tiger 10.4.7 update.
I will repeat my post and what was happening 2 weeks ago:
“In 5 years 10.4.7 update was a tragedy for my Powerbook Ti 667. When I update from 10.4.6 to 10.4.7 my 300 GB firewire drive gets corrupted, after repairing it with DiskWarrior and after connecting it to my PowerBook my computer freezes and I must shut it down via powerbutton. Safari also crashes after the update.
I just erase my Hard Drive and after that install 10.4 and update with combo to 10.4.7. But I had the same problems: finder freezes with connected firewire devices and also safari when browsing. I spend a week trying to solve the problem but no luck.
Yesterday and with no firewire devices, 10.4.7 freeze and I have big trouble in order to started my powerbook!!! Even when i insert the 10.4 install DVD it did not detected my HD. Finally I get it to work and install 10.4 and combo update to 10.4.6 and everything works. My external firewire drive and safari. I already diagnose my HD with disk utility, TechTool and directories with Diskwarrior and everything is ok.
I clone my 10.4.6 to firewire, boot from it and everything is working. I let my external drive connected and finder does not freeze.
My conclusion is that the problem is 10.4.7 update. It only give me problems and I was getting crazy with it. 10.4.6 is working good and I do not advice anyone to update to 10.4.7.”
Last week after reinstalling 10.4.6 I started to have HD problems with my Powerbook 667. I did a surface scan with TechTool I it reported bad sector. Then I done a zero disk format but after a second surface scan TechTool also reported bad sector. Then I take the decision to replace my internal HD. I bought a Samsung 40GB Hard Drive and installed it on my PowerBook. Then I have done a clean installation of 10.4.6 with all applications that I need and clone it to my hard drive with Intego Personal Backup software. Everything works on 10.4.6. and external firewire drive.
After that everything is ok. But I decided to test if my problem derivates from 10.4.7 update or from previous HD corruption. Then I install 10.4.7 update on my Internal Hard Drive. Everything is working good but after connecting my external Hard Drive the finder started to freeze!!!!!!!!!. After that I tried cloning HD to external firewire with Intego personal Backup. Everything was working good but when it was finishing the backup process started to give errors!! I started panic. I interrupted the backup process but after and after restart I found something strange with 10.4.7. The system started up, I login but I could not started any application!!!??? All my application died!
Then I have done one more clean installation of tiger and 10.4.6 update.
My conclusions are that the 10.4.7 update causes all the problems that I have on my PowerBook, because I used the same methods and same software/hardware on 10.4.6 and did no have any problem.
This last two weeks were very difficult to me. I tough that these problems do not happen with Apple computers but I was wrong!!! It is very hard to me to deal with it. I always said to my friends that I never had problems with Apple computers. I accept that a hard drive died because the use of it but I can not accept that a system update cause me 2 weeks of hard problems and make me loose precious work information! I always love apple computers and Apple OS but now I am disappointed
If anyone can explain what happen or have a solution for those problems?
Thanks for the comprehension and collaboration.
Best Regards

Hi, alsvieira.
There are some things you did not check in all of your troubleshooting:
1. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
2. re: FireWire troubleshooting: Here is some general troubleshooting advice that may help if problems return with your FireWire drive:1. Review the AppleCare Knowledge Base document "What to do if your computer won't recognize a FireWire device".
2. If this problem occurred after installing a recent Mac OS X Update, and you are also unable to mount CDs, DVDs, or disk images perform the steps in this Mac OS X Hints article. This worked under Panther and may also work in certain situations under Tiger.
3. Power-on the FireWire drive before starting up (booting) your Mac.
4. Reset PRAM and NVRAM.
5. Resett the power-management chip in your Mac.
6. Try a different FireWire port. James Wiebe, CEO of WiebeTech, has published FireWire Port Failures in Host Computers and Peripheral Devices, a white paper providing backgroud information and technical analysis concerning the causes of failure for FireWire ports. This may provide additional diagnostic information.
7. Micromat TechTool Pro version 4 can test the FireWire bus in your computer: this tests the bus — not the ports — but if the problem is on the FireWire bus on the logic board, it should reveal it.
8. Check with the manufacturer of your FireWire drive or enclosure to see if any firware updates are available for such.
9. Hopefully, the partition map on the FireWire drive is not damaged. This can happen if the FireWire drive was not Ejected before being disconnected or powered off. If it still refuses to mount, you may need to employ data recovery tools or services: see my "Data Recovery" FAQ.Note that some of the information above is from the "FireWire Problems" chapter of my book, Troubleshooting Mac® OS X.

External Firewire HD dead after iTunes 7 update - won't mount!

I have a pretty serious problem.
I have a 70gb music library that I keep on a Lacie Porsche 250gb external Firewire HD. The first time I ran iTunes 7, it gave me the spinning ball and locked up when "determining gapless information". I had to force quit iTunes.
A few hours later, the external drive started making a high pitched noise, and now it won't mount at all. It's also not visible in Disk Utility or Diskwarrior. I'm at a loss!
I have lots of very valuable information stored on my external drive, so I'm really hoping I can do something to revive it.
powerbook g4 500mhz Mac OS X (10.4.7)
powerbook g4 500mhz Mac OS X (10.4.7)

I recently had exactly the same problem with the 200GB model prior to the iTunes 7 update, so would concur that you're probably looking at a hardware quality issue. Thankfully the problems seem to be more related to power supply rather that the drive itself so you may be able to regain the data by swapping this over to a new external caddy as I did, but be wary of warranty issues.
Good luck ...

External Firewire HD won't mount after Connecting to B&W w/ bad Firewire

I've tried and tried to find the answer, so finally I post...
I've had two external Firewire Laptop HD enclosures become unmountable after hooking them up to a 400 Mhz powermac G3. This has been 6 months apart. I used to use the Powermac B&W ... I know the Firewire worked at one time, but cant remember if it was before or after I added a Belkin USB 2.0 PCI card.
After clean installing... 10.3.2 .... no Classic... I hoped it would wake up the Firewire, did not. So hooked up the external HD to the USB.... it worked. Then, went to the eMac and via Firewire hooke up the same external HD.... it worked.... for 2 hours. Disconecceted, reconnected and like the other one...... no more mount. Not in classic, not on any comuter. If I daisy chain it to another Firewire external, the About this Mac no longer recognizes info on either. Once removed, the computer recognized the info the good one. Disk Utilities does not recognize harddrives in the enclosure... I put a different HD inthe enclosure.. still not mounting
It spins and receives power.... but no mount. Is this firmware? The hard drive is not corrupted... I put it into a mac mini and was able to extract the info... but what has caused this B&W's fire wire to go, and caused 2 of my externals to go as well....
Help.

Welcome to Apple Discussions!
You can buy a 3.5" drive enclosure with USB that
supports IDE, remove the hard drive from the Firewire
one and put it in the USB enclosure. Mind you, the
iBook G3's USB is the old slow USB 1.1, and will only
transfer at up to 12 Mbps and can't boot off that
drive.
As for fixing the blue screen issue, once you have
your data backed up for certain, then you can go
ahead and check and see if the following will work on
the broken machines:

http://docs.info.apple.com/article.html?artnum=106464

And if none of those works, let us know more about
the broken machines one at a time, and we can see
what we can do to fix them.

ISight and External Firewire Hardrives

After installing my external firewire hardrive (one of two ports), my iSight seems to compete with the firewire ports and won't function. It just shows still frames, like an old film movie that got stuck between frames. When I turn the hardrive off, it works just fine. Problem: I'd like to run my external hardrive for daily backup storage . . . but then, I can't use iSight at all. Any solutions or fixes to this competition problem?
Thanks.
Rod

You're welcome, Rod
Sorry I was not clearer. The links are not for iMac firmware updates. Your Mac's Software Update... feature will monitor all updates needed for your iMac (unless you had disabled it, which you did not do.)
My suggestion to check firmware was intended to relate specifically to your hard drive's firmware.
Regarding your numbered questions:(1) Still dealing with your hard drive's firmware, your best answer will come from LaCie. Try their User's Manual, ReadMe files, Help files, or website Documents, Downloads, or FAQs.
For your Mac, just run Software Update... It will tell you whether you need any updates, whether to your Mac's Apple software or to its firmware.
(3) Yes, I believe you will still have a conflict. That is why I wrote that you can "try" using an external powered hub.
At the time of writing my response, I did not know how vital it was to you to have both your iSight and your external drive connected simultaneously and continuously. An external hub was just one more thing you could try if it were important to exhaust all possible remedies other than buying a Tower Mac and installing additional Firewire ports. (Even that might not work.)
If having your external drive connected while using iSight is not that important to you, there is no need to test whether an external hub might help you.As you read in the "hardware or software conflicts" link I provided earlier, the solution to my conflict between my iSight and my Firewire scanner was to disconnect the scanner whenever I use iSight.
Your solution of connecting your external drive only when you want to perform a backup is certainly a viable solution. Depending upon when and how frequently you use your iSight and run your backups, you might want choose the alternative solution of leaving your external drive running and disconnecting it only when you want to use your iSight. Whichever you choose, your solution will work.
Please let us know if you have any other questions.
Cheers,
Jim

External FireWire Disk will not boot

Hi Forum,
after some installations (OS 10.4.9, latest security update and Qucktime 7.1.6 I canot boot from my external disk (Lacie) connected to FireWire 800 port. The Apple shows up but then nothing more happens. Does anyone have a hint?
Thanks
Oliver

Add me to the list also. I had an external firewire disk as a RAID mirror for my boot disk. After a system crash (and some problem with my internal disk) I couldn't boot from the firewire stripe. This used to work.
I've tried creating a single-disk "degraded RAID pair" on the external disk and cloning the internal disk to it (using Disk Utility "Restore"). The cloning works fine but I can't boot from the copy. This is how I originally set up the RAID pair (clone, boot from clone, add internal disk to RAID group). This used to work. I bought a new firewire disk and it has exactly the same problems.
My original firewire disk was an Acomdata E5. My new firewire disk is a Coolmax Gemini CD-311 enclosure with a Hitachi 250GB deskstar inside.

External FireWire disk doesn't mount on Leopard, does on Tiger?

Hi All,
I have an external FireWire Hard Drive that mounts as it should on all our Tiger Macs, but is invisible on our Leopard Mac. If we swap the FW cable for a USB2 cable, it shows up.
Is this perhaps another Leopard 'thing' maybe? Like the one where Leopard couldn't erase a hard drive to FAT 32 like a Tiger could?
Cheers and thanks in ant...
Chris

"Methinks you're perpetuating a myth"
I'm too long in the tooth to either listen to or perpetuate myths of any kind! Not a myth unfortunately, a weakness in Leopard that was pointed out to me some time ago (when Harry Potter was a boy) by a sage far wiser and way older than you or I - and he was right, and more importantly brought to an end some hours of frustration with Leopard.
So there!
Thank you for your suggestions, which have made me think. It can't be the cable because it works with all the Tiger Macs. It might be the slot but if it is, I have two faulty slots which would be rare on a pretty new machine.

Finder hangs | external firewire hdd

hi list!
unfortunately my finder.app gets completely wasted very often, which is quite annoying. i think this has got sth to do with my external firewire enclosure (raidsonic icybox 351 usb2/fw combo, prolific chipset), which sometimes just stops working (eg. after hibernate). and only if i disconnect the drive or switch it off completely, finder (and all the other finder-like dialogs) reincarnates. i feel the problem came up more often after a firmware update (mac mini or smc), but i could be wrong. no probs with this drive with lin and win so far...
how can i unmount it more safely?
using umount /dev/my_ieee1394disc ?
any ideas, suggestions, similar experiences?
Mac mini Dual [email protected], 1GB RAM Mac OS X (10.4.6)

If you recently moved to Snow Leopard you might look for new firmware for your external drive. I would also get DiskWarrior and run that on the external and consider programs like Drive Genius. You might also back it up and wipe it and restore the data. After that I'd consider looking at a new external.
Sleeping drives that take time to spin up after waking....I'd like to learn how to stop that myself. Be sure the Energy Saver in System Preferences is set to not put drives to sleep when possible. Even then my drives will go to sleep and I have up to 6 external added at times and they take quite a while to all spin up. I've never found a way to prevent that.
BTW...external USB drives on a MacPro? Really? Even for backup....
