Internal OS 9 boot disk

Hi,
I've got me a spanking brand new second hand 533 mhz dual CPU desktop G4, digital audio Macintosh. Frankly, I'm thrilled. It works great! It has a fresh install of 10.4.6 and 9.2.2.
My older machine would not boot in OS X. This new machine will boot with OS 9, though. That's handy for me. I have lots of old but expensive OS 9 software, still very useful. Sometimes it's better to boot in OS 9 than to run in classic mode.
I moved the 80 GB hard disk from the old machine to the new machine. OS X recognizes it, I can read and write to and from it, the OS X version of Disk Warrior rebuilds it, and the "startup disk" control panel recognizes that it has a valid OS 9 sytem folder on it. However, the machine will not boot from it. The old OS 9-only machine booted from it just fine.
There must be something I don't understand. Please clue me.
(If you're wondering, I do have two valid OS 9.2.2 system folders. One is on the original hard drive, along with an OS X system folder, the other is on the second hard drive.)
Thanks in advance,
Tim

Hi, Timothy.
You're posting on the wrong Discussion. This isn't a Mac OS X problem. You should post your question on either one of the Power Mac G4 Discussions or one of the Mac OS 9 Discussions.
As a quick pointer, it may have something to do with how you've installed the second hard drive. Your Mac may employ either Cable Select or require drives be set as Master/Slave. If you pulled the old drive from another Mac, both drives may be set as Master if your Mac employs Master/Slave. You'd have to set the jumpers on the second drive for Slave if that's the case. That's a hardware question for the Power Mac G4 Discussion or something to look up in the manual that came with your "new" Mac re: installing additional hard drives. If you don't have the manual, you can probably download it from See Apple Manuals.
One other thought: see if you can start up from the second drive by selecting it in the Startup Manager.
Good luck!

Best Practice??? Change from internal boot disk to external disk

I have a mini running 10.5.6 server and it currently boots off it's internal disk. I was hoping to get some feedback/input from others on a good process to convert the system from it's internal boot disk to an external boot disk (firewire).
I wanted minimum downtime during the conversion and I of course, want a complete snapshot on the new boot disk. Lastly, I do not have a local keyboard and console on the system although I could connect one if it seemed to be much easier that way.
In general, I am thinking of the following:
1) Boot into the Leopard Server CD.
2) Use diskutility to Restore from the internal boot disk to the new external boot disk.
3) Choose the new boot disk as the startup disk.
4) Reboot onto new disk.
Is diskutility the best bet?? Meaning will it work this way if the drives are different sizes??
Should I try to clone the disk from the internal boot disk (assuming I shutoff services first) using SuperDuper or Carbon Copy Cloner?? But I believe they do not copy over all logfiles, etc..
Or does anyone have a quick overview of a methodology which they have done in the past or just are suggesting might be a better process than the ones I described??
In Summary:
1) From the CD, clone using diskutil and change boot disk
2) From the running OS, clone using SuperDuper or CCC and than reboot onto new disk
3) Something else??
Thank you in advance.

For cloning the machine you have the approach fine. Disk Utility is fine and booting from the CD is the best method. Simply use the restore method.
But why on earth would you want to boot from an external Firewire drive? First, there is the issue of speed. You have a mini, let's assume it is a one generation back Intel. It has an internal SATA drive on a 1.5 Gbps connection. You want to move that to a 400 Mbps Firewire bus? Next, beyond the speed issues, you have a persistence issue. You are taking the boot volume and moving into to a transitory bus. One of Firewire's greatest strengths is easy connection/disconnection. Persistence is not a strong point.
Next, if your plan is to move the boot volume to some form of a Firewire RAID, then you are even penalizing yourself more. The mini has one FireWire port. If you are using two devices and creating a mirror RAID, then you need to daisy chain. Talk about points of failure, asynchronous startup time, bus blocking, etc. Not wise.
Plus, I can not count how many external firewire devices have burnt up in the effort to have small footprints. Lacie and the "let's put a drive in a metal case with no fan" approach = melted drive. Western Digital and Lacie with the "let's make a completely un-reusable external power brick that either breaks in a small breeze or falls out when the heavy guy walks by the server" approach.
If you are looking at a Firewire RAID enclosure, then you are missing the objective of speed as you are limited by the 400 bus. It is nice to say that you have a four drive SATA 2 RAID case running a RAID 5, but you are defeating the purpose of why you bought the raid. The RAID 5 can provide an exponential increase in I/O performance. But that goes out the window because of the slow bus.
If your argument is that "this is a server and my bottleneck is Ethernet," that too does not hold up. You are likely running on a gigabyte network.
For system details check out http://developer.apple.com/documentation/HardwareDrivers/Conceptual/Macmini_0602 /Articles/architecture.html.
Take this with a grain of salt. You caught me on a grumpy day as yesterday I dealt with a melted external firewire drive.
My advice is buy real server class hardware. What is you objective? Drive redundancy? Capacity? A mini is a great dev server. Not a production server. This is your data. Presumably the data that makes your business function. Don't trust it to a single platter. And don't trust it to a consumer level, disposable system. I am not trying to malign the mini. It is a fine machine for its role. Its role however is not to be a production file server. Now as a web server, we are talking a different situation.
Ok, I am rambling. Hope this helps in some way.

Error message comes on screen: No bootable device -- insert boot disk and press any key. What do I do?

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
If the above is not possible or failes, then replace your hard drive.

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!

No Bootable device insert boot disk on iMac Wireless

Hi,
We just recently bought an iMac with Intel just a month ago. Earlier today my computer completely froze so I restarted it. When I turned it on. I received the "No Bootable device--insert boot disk and press any key". Well with the new computers, we did not receive a disk and there is no disk drive in the machine. I have an external disk drive and I unfortunately do not have an external hard drive either. I have most of the files saved on a separate computer.
I looked online and saw that when you restart the computer you can hold the Option key and it will bring up all the systems. It does work and it gives me two options. One is the windows and the other one is a hard drive but its not the OSX hard drive. I've tried both and they both do not work and send me back to the message "No Bootable device--insert boot disk and press any key". We just bought it less than a month ago and I also have a 3 year support and coverage on it that covers problems if need be but I would like to try and fix it myself.
If anyone has any other ideas or tips please let me know.

OK. That's not the best news. I can take you through some Terminal commands to attempt to mount the volume if that's possible. Or, you can just erase the volume and reinstall OS X. I suppose your choice here depends on whether you have backups of your files.
Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Hard drive failure (why can't I start up with boot disk)?

Running OS 10.4.6. I was getting flashing question mark at startup. Tried starting with Disk Warrior holding down "C" key. Got Apple logo, but then screen frooze with horizontal lines across screen.
Rebooted, held mouse to eject disk. Tried TechTool Pro disk. Would not boot from that either (got circle with slash logo I think).
Finally was able to boot with Tiger install disk.
Ran disk utility from Tiger disk. My internal hard drive showed up in red letters and said "failing"
OK.....I can understand that.....I guess my hard drive crashed (on my 2 year old Powerbook...oh well)
But, why can't I start up with any of my boot disks (Disk Warrior, TechTool) only the Tiger install disk. Also the Panther and Jaguar disks will NOT start it...only the Tiger disk works. One more thing I'm wondering....I connected my external firewire drive that has a boot partition on it that I have started up with in the past....and it won't boot my laptop either.
Any ideas? Thanks for any insight. Guess I'll head to the genius bar tomorrow. At least my extended warranty is still good (I think).
Powerbook G4 17 1.5 ghz Mac OS X (10.4.6)

Here is what the outcome was:
I took my Powerbook into Apple Genius bar (still under 3 yr. AppleCare), he determined that my hard drive had crashed. He shipped it for me to be repaired.
It came back with a message attached saying that the source of the problem was my 3rd party RAM, which was a 1 GB module. The note said that the memory had been removed...and that in some cases like this the removed memory will be sent back to the customer and will be in the box somewhere. I checked and it wasn't there. The "Get Info" for my system said I was now running on 512 mb instead of the usual 1.5 GB. The note said that this 3rd party RAM had caused the hard drive to fail, so the hard drive had been replaced.
I ordered a new 1GB RAM module from Apple for $300, didn't want to take a chance on 3rd party again. But....when it arrived, I went to install it....and my 1GB 3rd party module was in the slot....it just wasn't pushed all the way in I guess. I pushed it in firmly, closed up the computer, started it, and the "Info" read 1.5 GB again. I ended up removing the 512mb module and replacing that with the new 1GB one I bought from Apple. So now I have 2GB of memory and and extra 512 that I can't use. It has been running fine ever since (more than 2 months)
Can bad RAM really make a hard drive go bad?
I wonder why they said they had removed the RAM, but it actually had not been removed (at least not completely)

Satellite Pro A200: Recovery using a network ghost boot disk

Hi all,
Need to ghost several sat pro a200 machines using a network ghost boot disk. when i use the ghost disk provided by ghost boot wizard and booting into PC dos i get the message "No Fast Ethernet PCI Adapter Found!" Serious Internal Error! (hardware works OK in XP/Vista)
i have tried booting from CD, Mem Stick and USB floppy with drivers from toshiba and realtek without any success, searches on google seem to point toward there needing to be a driver to interface with the cardbus / PCMCIA adapter - if this IS the case can anyone shed any light on the whereabouts of such a driver and how i could go about doing this?
Many thanks,
Gav Shakespeare.

Sorry folks answered my own question - the network card is reported as being an RTL8134 in windows XP but is in fact an RTL8100E/RTL8101E so i was using the wrong NDIS2 Driver!. doh!
emergency over.

How do I create a new boot disk from an existing one?

I have a G4 Quicksilver with internal PATA disk, running 10.4. I want to upgrade the internal disk from 40 GB to 160 GB. I have installed a second disk and can see it fine, but what I really want is to put the system on the new disk and have it be the one and only boot disk in the system. Is there a straightforward way to do this? Is a carbon copy cloner the way to go? Will that have problems with the different disk sizes? Will it handle bad blocks properly? Isn't there a way to just use drag-and-drop?
Once I have made a copy, how do I make it the boot disk? Do I have to swap it into the PATA "master" position to do this?

Cloning And Backup Tools
A bootable clone is an exact copy of your drive which is capable of booting your computer. Making a copy of your computer which is capable of actually starting the computer requires special copying procedures. Some people just back up data files but if you have problems you have to reinstall all your operating system and all your applications. With a bootable clone you just start up from the backup drive and clone back everything.
To copy files from one hard drive to another hard drive you can use:

How I make a boot disk

Hello.
I'm an absolut Linux beginner and I tried to install archlinux on an external HDD, because my internal windows drives are dynamic logical Volumes and this doesn't work with Linux.
After the installation from the CD I noticed that I cannopt boot from USB HDD because of the BIOS.
How I make a boot disk (floppy) now ? The wiki guide doesn't help because if I boot from the installation CD I don't have the command fdformat and the command pacman - S grub works neither.
Can you help?
Best Regards
BX-8017
Excuse by bad language please, I'm not english!

Ok,
I found a grub boot disk on the net, it was a super grub boot disk. I deleted nearly all files and just copied my files from /boot/grub in the grub directory of the floppy disk. I used the windows tool "explore2fs" to get acces to my boot partition with the grub directory.
Her is my menu.lst:
# (0) Arch Linux
title Arch Linux
root (hd2,0)
kernel /vmlinuz26 root=/dev/sdc1 ro vga=773
initrd /kernel26.img
# (1) Arch Linux
title Arch Linux Fallback
root (hd2,0)
kernel /vmlinuz26 root=/dev/sdc1 ro vga=773
initrd /kernel26-fallback.img
# (1) Windows
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1
It doesn't work, because the hd 2,0 is not found from grub. (Selected disk does not exist)
It seams that grub is not recognizing my usb hdd at start up ?!?! but this cannot be, because during the installation process it is.
Many Thanks
BX-8017
PS The possibility to boot Arch with the Windows Bootmanager is interesting. Maybe we can discuss this later.....

Advice for settip up a SSD for my boot disk

I am running an early 2008 Mac Pro 2x2.8 Quad-Core Xeon machine. I currently have 2 1TB drives. I would like to put install a Solid State drive as my boot disk and switch the current 1TB boot disk to another bay for a total of 3 drives. Can anyone advise what I would need to get in terms of space/product/connection type in order to do this? I have a lot of applications, 33GB worth, and my System and Library folders are about 30GB as well. Thanks in advance for any advice!
Cheers

Boots in ~19 seconds (instead of ~25 seconds with default disk). Spotlight is very fast, overall performance is very good. AFAIK the controller uses some implementation of internal garbage collection, ATA-Trim is not available in OSX.
The SSDs are available with more capacity (160GB). Double the size and you double the cost. 80GB cost ~200 Euro, 160GB cost ~400 Euro. Look for SLC instead of MLC chips and you find yourself spending roughly 800 Euro for 64GB capacity. Which SSD is for you depends on your needs. Most (if not all) recent SSDs are more than fast enough to beat most if not all HDDs in terms of throughput and access time.
Whatever SSD you are buying, you need an extra drive carrier because those SSDs are 2.5". Using the adapter shipped with the retail version of the SSDs doesn't work with the backplane. I've bought a drive carrier from Kingston[2] which costs ~20 Euro.

External 'boot disk' for G5 won't boot

First attempt was to make an OS 10.5.? boot disk from the installation DVD. The second attempt was to use Carbon Copy Cloner to make an exact duplicate of the internal Boot Macintosh HD disk. Both onto one of a pair of external 4Tb Iomega drives. Connection is Firewire 800 daisychain. The external drive in question is the last in the daisychain. The G5 has twin internal drives already and the G5 will boot happily from either. (One is 10.5.8, the second is 10.4.11/Classic.)
Both installations attempts on the #2 4Tb drive appeared to "work". The now CCC version is an exact copy of the main internal drive and is OS 10.5.8. 'Startup Disk' appears to recognise it as a system boot disk. I can select it for booting on restart but it fails to do so and eventually finds the main internal drive after some wait.
Holding down the Option key as you restart the machine brings up just the two choices of the two internal drives to start from - no external drive choice.
This all used to work just fine in the days of SCSI...
I'm presuming altering the order of the external drives on the Firewire chain won't make any difference?

I wonder if such a drive is just too big to boot a PPC Mac.
Hmm. Interesting thought. You have a good point.
I just found this technote:
*Secrets of the GPT*
http://developer.apple.com/library/mac/#technotes/tn2166/_index.html
It contains the following regarding the Apple Partition Map scheme:
APM is restricted to 32-bits worth of blocks. With a standard block size of 512 bytes, this translates to a maximum disk size of 2 TB.
In Disk Utility, if you again click on the upper icon as before, and look again at the lower right of the window, what does it say for "Total Capacity?" Does it report the full 4TB?
It reports the full size - strictly it reports 3.6Tb - ie well over 2Tb.
(I do have the hardware option of switching to twin 2Tb on these 4Tb Iomega drives and strictly, that is what is inside the physical housing. It's a matter of throwing some switches. Of course, I don't actually want 2Tb drives. )
MacBook Pro (10.5.8) Power Mac G5
It might be of interest regarding the capability of the drive enclosure hardware to connect the drive to your MacBook Pro, repartition it as GUID (which will erase it), install OS X on it or clone the MBP to it, and then see if the MBP will boot from it.
Hmm. I don't think I want to do that as the MBP is an Intel machine and the G5 isn't. It won't solve the actual problem. (At least I can't see how it will.) Though I see what you are getting at.
It's probably worth a shot emailing Iomega, I guess.

External boot disk, options?

Hi all I am considering buying a new mac mini which comes loaded with Mountain lion,
I want to have an external boot disk with Snow Leopard, so that I can run some legacy Rosetta apps
Q1. will Snow Leopard run successfully on the latest mac minis?
Q2. what is my best option for an external boot drive
I want a drive that will be ideally powered from the computer and that wakes up fast enough to boot an OS without the computer defaulting to the internal Mountain Lion OS
USB or firewire, whichever is best
what are your reccommendations?
cheers Robert

The current Mac Mini (mid-2011) can be retrofitted to have Snow Leopard work on it. There is a very comprehensive thread here on this site.

PSCS5 will not open from external boot disk

Because OS 10.8.2 was the worst update in Apple history, for the first time ever I decided to do the 10.8.3 update on an external boot disk before sacrificing my internal disk. I used Super Duper to make a bootable clone of my internal , booted from the external and then did the combo update. It seemed to be ok although they didn't fix the scroll bars in Safari as I had hoped. The first app I tried was Photoshop CS 5.1. It tried to open but I got a window that said "could not inialize scratch disk because disk could not be found". After I clicked OK on that, another window said "could not open because disk could not be found" . I have never tried to open Photoshop any version from a bootable backup before and I don't know what this means. The scratch disk for Photoshop is set to be my internal drive Macintosh HD. Why would it not find it? If I were booting from my internal and had set the scratch to the external it would find it. Why would the app be looking for itself on another disk?
After recloning my internal which is still 10.8.2, I have not yet booted from the external to see if the problem was somehow caused by 10.8.3, but I wouldn't be surprised if it was. People have reported the usual weird behavior of an upgrade already on forums, but not this paricular problem
I am runninga 2011 mini with dual i7 and 8 GB of RAM.

Just to be clear, resetting the Photoshop prefs is troubleshooting 101. I'll admit that since Photoshop CS and OS X, the need for resetting the prefs has gone way down (although I had a lot of problems when Photoshop first included GPU).
However, if you EVER have a hang/force quit or an actual crash, you should seriously consider resetting the prefs because, well, in a hang or crash, that's when pref can get corrupted...afterwhich Photoshop can misbehave and cause problems.
But in this case, resetting the prefs was a fix for the issue where the exact directory path for a scratch disk no longer existed and thus kept PS from even launching...
Although the OP hasn't given an update, I'm 99.9999% sure his Photoshop is back to launching correctly...and that the issue was fixed by trashing the prefs.

Create boot disk?

Hi,
I am away from home, and I need to create a boot disk, and I do not have my system install DVD. Anybody know of a solution to create a boot disk, either on a removable media or an external HD? It seems like I should be able to create a partition or a disk image on my firewire drive and copy key system files to it and start from there, run my utility programs. Restart and life is good again.
Any thoughts?

Clone your internal drive to the external using CarbonCopyCloner or SuperDuper!, then boot from the clone to run the utilities.

Simplest way to protect the boot disk

I have a solaris T2000 machine.
It has two internal disks - and it boots off one of these. The disks are not in an hardware or software RAID configuration. There is nothing on the second disk that I cannot move. Please don't ask why this wasn't setup from the start - I had no control over it.
So, what is the simplest way of getting around this single point of failure with the minimum of disruption to the service the box provides?
1) To implement hardware RAID using raidctl would require a re-install of the OS - I do not want to have to do this
2) Is it possible to create a new disk from the SAN, copy the boot areas etc and make then make the machine boot from the SAN?
3) Use solaris volume manager to implement some kind of software RAID on the second disk?
4) The boot disk is currently an ufs file system - could we convert this to zfs and then implement zpool mirroring without the need for a reinstall?
Many thanks

In my opinion, the simplest is option 3. Here's some instructions on how to accomplish:
http://wikis.sun.com/display/BigAdmin/Mirroring+root+With+Solaris+Volume+Manager+in+the+Solaris+9+and+10+OS
However, if I were in your position, I would do option 4. Use liveupgrade to convert to zfs and use zpool mirroring.
