Will new OSX install erase files on HD?

drhfk · 06-29-2003, 08:37 AM

I have two HDs in my 400MHz G4, a boot drive and a backup drive. The boot drive apparently just died; when booting from the CD, it doesn't even show up as a choice for a system install any more. The backup drive contains most of my data. Can I install OSX to the backup drive without corrupting my data? Thanks, drhfk

mervTormel · 06-29-2003, 12:59 PM

yeah, but i recommend you consolidate all the top level dirs of your "backup" drive into one dir called something like 'precious' or 'myData' or 'scoobySnax' and make darn sure you don't do an erase install.

if there is any way to do a backup, that is recommended, also.

is the boot drive the original? can you tell if it's spinning?

rusto · 06-29-2003, 01:21 PM

Or perhaps you could boot off an OS 9 install disk and try to reformat the wayward disk with Drive Setup.

anthlover · 06-29-2003, 01:31 PM

Scoobby

Anyway Its called Archive and Install with and with out saving user settings. Which works well.

You did not Sepcify what you prior OS was and what you version of X you consider new.

We all are assuming Jaguar OSX 10.2 as the new and then System Updating or manual updating to 10.26 and counting (we are not sure what you have/had now for an OS though).

------------------------------

While running Jaguar Archive and Install with saving user settings is safe (we would all be doing you a dissrervice if we did not urge you to back up your data (prior to even a safe procedure (accidents happen). e.g. you have to know to *** To Go to options and not blow write into Format and Install.

If you are hardware Handy. You Should be able to disconnect the Illin Drive. If you are unsure whcih it is reboot after disconencting it (you will find out pretty fast if it is the wrong one as now neither will show up).

You usually can safely just disconnect power connector rather then the Drive's ata Cable (more delicate) (at least for the quick test).

------------------------------------
We would also recommend that you buy a second drive that might very well become either your new back up or ***your primary drive, more likely. 80 Gig Drives are available for under $100. And if it you are price sensative you might save $20 to 40 so bucks on a 40 or 60gig.

With this New Drive you could build your New system, restore your data from your back up and get back to work. Once complete you could use your old back up drive as a key element in trying to safely restore your dead/dyin drive.
--------------------------------

Most of us would strongly suggest Disk Warrior X at first pass for Repair. If the Drive Does not Show up to even be formatted by Disk Warrior or Apples Disk Drive Util it might be beyond repair.

There are other possabilties such as the ATA controller on your computer going bad.
--------------------------------------------------------
We are also presuming No spin folding or mutaling of the guts of your computer. No one been playin with Drive Jumpers, Adding more drives, Plugging and Plugging ata cables etc. If any of this happened you might have bent pins, or an ata cable thats been flexed to hard etc.

--------------------------

drhfk · 06-29-2003, 10:18 PM

Thanks very much for your suggestions. Since the drive is still spinning I guess I'll give Disk Warrior 3.0 a try; Apple Disk Aid didn't fix the problem. (I'll have to get the boxed version of Disk Warrior, since CDs created w/ BootCD on my PB 12" won't boot on the PowerMac.) I will probably also order a LaCie 120GB firewire drive. Thanks again. drhfk

anthlover · 06-30-2003, 10:42 PM

Good Luck.

As you are going with a larger drive you might want to consider several paritions.

You then can create multiple back up Clones using Carbon Copy Cloner.

They can merely be multiple back ups (read historical) with different snapshot lags to allow you to roll back to different time frames or you can have a main Back up clone and one you use for trying out all the hacks and crap with fear, and of course one of the Paritions can be for Data to.

*** While you should have back up drives (the firewire one you are ordering). I wanted to point out that you can Plug a firewire cable between your computers. You can then Reboot which ever one you want to turn into Firewire HD for the other. That is You could reboot the Older machine and it will become a Firewire Drive to PB and you can run all recovery surgery from the Powerbook.

wow I had no idea you could do that... thats agreat idea for when I get my G5... backup my laptop on that piece and away I go

grrl_geek · 07-02-2003, 01:53 AM

Yeah, it's called "Target Disk Mode" for whatever reason. You can do it by holding down the "T" key as you start up your OS X Mac. It's really really convienent for moving a lot of stuff quickly between two computers.

anthlover · 07-02-2003, 07:21 AM

It is a feature

**** Thanx I neglected to mention proper name and holding the T down on system you want to be master.

drhfk · 07-02-2003, 10:30 PM

Oh well... I went to the Apple store and bought Disk Warrior 3.0, which fought a valiant battle (I guess) but finally had to concede defeat. Apparently I screwed up whatever was left of the directory table by using the repair function of Apple Disk Aid (or whatever the disk utility is called that's on the boot CD.) In the olden days (of DOS) I would have at this point resorted to a hex-editor and searched the drive block by block for some of the content that I wanted to rescue, but I don't know how that works in OSX. Any ideas?

lerkfish · 07-03-2003, 12:16 AM

I'm very interested in making sure I understand this target disk process properly. I"ve read the apple article and what you guys have said, but is unclear in just one little part...that of whether you're restarting with "T" the computer that will be the hard drive to the other, or vice versa.

I think I have it, but please correct me if I'm wrong. I will have to do this procedure in August when I get my G5. My present G4 yikes has three hard drives in it with valuable data, totalling 120 gigs. So this is a real world scenario. If I understand you correctly, here is what I must do. I will highlight the part that I could be wrong about. I want to transfer files FROM the yikes TO the new G5.

POSSIBLE PROCEDURE A:
1. connect the firewire between the two computers.
2. Boot Yikes, with data to be moved.
3. Boot G5, holding down T on the G5 as the G5 boots, making it a target hard drive visible to the Yikes.
4. From the Yikes, copy files to the G5 on the Yikes desktop.

POSSIBLE PROCEDURE A2:
1. connect the firewire between the two computers.
2. Boot Yikes, with data to be moved.
3. Boot G5, holding down T on the Yikes as the G5 boots, making it a target hard drive visible to the Yikes.
4. From the Yikes, copy files to the G5 on the Yikes desktop.

POSSIBLE PROCEDURE B:
1. connect the firewire between the two computers.
2. Boot G5, .
3. Boot Yikes, with data to be moved, holding down T on the Yikes as the Yikes boots, making it a target hard drive visible to the G5.
4. From the G5, copy files to the G5 from the Yikes on the G5 desktop.

POSSIBLE PROCEDURE B2:
1. connect the firewire between the two computers.
2. Boot G5, .
3. Boot Yikes, with data to be moved, holding down T on the G5 as the Yikes boots, making it a target hard drive visible to the G5.
4. From the G5, copy files to the G5 from the Yikes on the G5 desktop.

so, which is the correct procedure? Its difficult to absolutely tell from what I've read so far, depending on a mutual understanding of the terminology used.

thanks in advance.

anth:

i hate to question, but isn't it the other way around? i've done this before, and i think it's a little easier than you describe.

let's say computer Foo has the goods. so let's put computer Foo into firewire target disk mode. touching Foo right now, and only Foo, boot it up with the T held down after the chime. you'll get the bouncing firewire logo. Foo is ready to be mounted.

now we have Bar, the fancy fresh new G5. turn it on completely normally. log in. once your desktop loads, just plug a cable from Foo into Bar.

Foo's internal drives all mount on Bar's desktop.

i think this is easier, in that you're copying files from the older drives onto the new system that's currently running.

yes, thanks guys. You see how these instructs get confusing just on that one element of the process, no matter how many different sources you read. Since I don't have the G5 yet, I can't test in real world, so I'm depending on you fellas with actual experience. This will also be good for anyone else happening upon the thread, and frankly, should probably be sent in as a hint or its own thread. One of you experienced fellas might want to do just that, especially since I will not be the only one in this situation as the G5s ship.

anthlover · 07-03-2003, 08:33 AM

Going from Memory Last did this about 9 months ago..... (My memory on the subjet had been off on that one detail).......

-------------------------

Everything Else holds true. You will need to reboot the system that needs to go into Target mode to have it become Firewire drive/s.

When I had done this, I did with the two system already Cabled together.

JD indicates you can cable them together after booting up the system as a Firewire Target. I was under the impression the systems had to pre-cabled together. This Pre Cabling was correct, but does not always work and yet it is Apple default method.

anthlover · 07-03-2003, 08:39 AM

RE: If Both Computers Still have a funtional and bottable OS:

You can turn either computer into a Slave or "Fire Wire Hard Drives" for the other.

e.g.

1) With Both Computers On

****** Apple Says in a trouble shooting document you might be better of/some systems cabling them together after.......

2) From the Computer you want to become Slave Hold down the T Key on this Keyboard (do not let go, or you will have to start over). ****Reboot.

********** This works with older Systems to even, ones that have 9

3) The result, Giant floating Firewire Logo on computer where you held T Key down, *****Cable the system together, ****whom I to ? Apple trouble shooting doc

4) The Drives of this computer now show up on the other computer

5) When done dismount Firewire drives from comuters desktop as you always do by putting the icon over the trash which turns into an eject icon....

anthlover · 07-03-2003, 08:48 AM

Offical from Apple JD was Mostly correct and for trouble shooting I see No reason not to use Trouble Shooting Methodolgy over Default one:
-----------------------------------------------------------------------------------
How to use FireWire target disk mode

Important: Unplug all other FireWire devices from both computers prior to using FireWire target disk mode. Do not plug in any FireWire devices until after you have disconnected the two computers from each other, or have stopped using target disk mode.

To use FireWire target disk mode

1. Make sure that the target computer is turned off. If you are using a PowerBook computer or iBook computer as the target computer, you should also plug in its AC power adapter.
2. Use a FireWire cable (6-pin to 6-pin) to connect the target computer to a host computer. The host computer does not need to be turned off.

3. Start up the target computer and immediately press and hold down the T key until the FireWire icon appears.

------------------------
*** Apple leaves out the commandment here/at this point to Cable the systems together, if you have not already [in a trouble shooting document this is apparenlty the safer time to conect rather then before the other systems reboot]****
That is some system work fine PreCabled Prior to Reboot of one system and Target mode, Others require Post Cabling.
------------------------
The hard disk of the target computer should become available to the host computer and will likely appear on desktop.

4. When you are finished copying files, drag the target computer's hard disk icon to the Trash or select Put Away from the File menu (Mac OS 9) or Eject from the File menu (Mac OS X).

5. Press the target computer's power button to turn it off.

6. Unplug the FireWire cable.

Norton and Data Rescue Offer this file level function: Both require a separte disk to recover too. DW only rebuilds dir. it can find, not files that have gone missing or erased.

First Aid it pretty safe though... Alsoft/DW always says to use them first to get max. chance to save your stuff.

Word to the wise do not to the exaustive scan on Data Rescue on a large drive, I had it running for two weeks on an accidenly inited drive (on a 40, no that large

.
Maybe for a non inited drive its faster. They offer a free working demo you pay if it works and you want to save more then one test file.

drhfk · 07-05-2003, 07:11 PM

I hooked up my 12" PB to the G4/400 via firewire cable, both machines off. Started the PB with "T" pressed, bouncing firewire symbol appeared as advertised. Started G4 with defective HD, after a while the G4 boots from the PB HD. Ran Data Rescue X from the PB, which found the dead HD. After about 20 minutes, the "thorough scan" ended with a message that the drive was gone for good ("no data received from drive for 5 minutes. [...] hardware defect."). After restart, Data Rescue didn't find the dead HD any more. Anyway, at least now I know that I have exhausted my options. Thanks again everyone for your help!

anthlover · 07-06-2003, 08:53 AM

You did run all recovery Options from the Newer funtioning System the Powerbook?

You did Hold the T key down on the System that had the Flamed out/Dead Drive the G4/400.
-------------------------------------------------------------------------
I am sure you Picked it up elsewhere in this thread and others. System that will become master that is not Going to have the Firewire symbol can Stay on.
----------------------------------------------------------------------
Only the System that you want to put in Firewire Target Mode needs to be rebooted with T Key Held down.

Apple Directions Indicate that

********for some systems it is better to Pre Cable them together prior to putting one system in Target Mode

***********and Yet with Others it suggests Cabling After one of the Systems Goes into Target Mode.

Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. ------------------------ * Apple leaves out the commandment here/at this point to Cable the systems together, if you have not already [in a trouble shooting document this is apparenlty the safer time to conect rather then before the other systems reboot]** That is some system work fine PreCabled Prior to Reboot of one system and Target mode, Others require Post Cabling. ------------------------ The hard disk of the target computer should become available to the host computer and will likely appear on desktop. 4. When you are finished copying files, drag the target computer's hard disk icon to the Trash or select Put Away from the File menu (Mac OS 9) or Eject from the File menu (Mac OS X). 5. Press the target computer's power button to turn it off. 6. Unplug the FireWire cable. ------------------------------------------------------------------------ Full Apple Docs on the matter below: How to and http://docs.info.apple.com/article.html?artnum=58583 trouble Shooting http://docs.info.apple.com/article.html?artnum=75420 Last edited by anthlover; 07-03-2003 at 09:34 AM.

Started the PB with "T" pressed, bouncing firewire symbol appeared as advertised. Started G4 with defective HD, after a while the G4 boots from the PB HD. Ran Data Rescue X from the PB, which found the dead HD. After about 20 minutes, the "thorough scan" ended with a message that the drive was gone for good ("no data received from drive for 5 minutes. [...] hardware defect."). After restart, Data Rescue didn't find the dead HD any more. Anyway, at least now I know that I have exhausted my options. Thanks again everyone for your help!

You did Hold the T key down on the System that had the Flamed out/Dead Drive the G4/400. ------------------------------------------------------------------------- I am sure you Picked it up elsewhere in this thread and others. System that will become master that is not Going to have the Firewire symbol can Stay on. ---------------------------------------------------------------------- Only the System that you want to put in Firewire Target Mode needs to be rebooted with T Key Held down. Apple Directions Indicate that ******for some systems it is better to Pre Cable them together prior to putting one system in Target Mode *********and Yet with Others it suggests Cabling After one of the Systems Goes into Target Mode.
