OS X :: Can't Boot From External Hard Drive (usb)?

Mar 13, 2010

Sorry if I am in the wrong forum, as you can guess im a newbie at the forum - not at computers though (6 years experience.. )

So I have a 1TB WD Hard drive USB and I copied the Leopard Disk image and restored it onto it in a 500GB partition.

I have tried to boot it up normally by holding down Alt on start up but the drive doesn't come up. Ok.

I have tried going into the Start up Disk, it comes up and when I click on it and click restart it doesn't restart, it just does that Mac Beep thing.

I have recently just tried to boot it up manually using the Open Firmware technique. It doesn't work.

I have a PPC Mac and I know that they can't normally boot up USB Drives but the other users which I read on the thread how to boot up by the Firmware technique said they're PPC and it worked.

I just wanted to format my computer, My leopard disk is gone now but I got it copied JUST IN TIME to my Hard drive.

I formatted my computer and now i'm stuck on Tiger.

Intel Mac :: Using External Hard Drive As Both A Boot Drive And Timemachine Backup?

Mar 8, 2012

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups?  It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it?

OS X :: How To Boot Up From An External Hard Drive

Jun 25, 2010

I want to make a bootable clone of my iMac (PowerPC G5 running OS 10.5.8) and also backup my MacBook Pro onto an external USB hard drive so that I can restore from the external hard drive if my iMac dies (which is beginning to have startup problems).

I was planning to create 3 partitions - one for iMac's data which I'll continue to backup using TimeMachine, one for my MacBook Pro's data and one partition as a bootable clone of my iMac.

My question is.... if my iMac dies, how do I use the external hard drive to boot up from? Do I need Carbon Copy Cloner or will I be able to boot up from the external hard drive and access Apple's Disk Utility?

Software :: Boot From An External Hard Drive Via USB?

Jul 8, 2009

My imac G5 isight's hard drive is dead. I would like to install OS X on an external hard drive and just use that as the hard drive for this machine. My questions are:

Can I boot from an external hard drive via USB and just run everything off the external hard drive? If so, how should I format the external hard drive so that it can be selected and written to when I boot from the install cd? The external hard drive I would like to use is a 75 gig Acom. I've tried booting from the install cd, and it either won't even find the external hard drive, or, when it does, it says it can't write to that external hard drive.

IMac :: Won't Boot Linux From External USB Hard Drive

Nov 14, 2010

I have an Intel iMac with with Snow Leopard and Windows 7 on separate partitions. Recently I have acquired an external USB hard drive. I formatted it with Ext4, and installed Linux Mint to it.

The installation went smoothly, but I can't seem to boot from the USB drive anymore. Holding down Option on start-up only gives me two choices: Mac OS X and Windows. The drive isn't recognized in either operating systems anymore: on Snow Leopard I get "The disk you inserted was not readable by this computer" and on Windows, it doesn't even show up in My Computer.

Mac Mini :: Will Not Boot From CD Or Hard Drive, Internal Or External

Jan 23, 2009

I have owned a Mac Mini for three years now (my friends convinced me to try the Apple way and this is my first Mac). The CD/DVD died just three weeks after warranty expired and Apple said (in essence) 'tough crap...you didn't buy AppleCare'.I have functioned without a CD/DVD drive since then, and everything was fine... until a week or two ago. We installed an update in iTunes, and everything started running S...L...O...W... So, we rebooted the computer! Instead of rebooting, it made the "bong!" sound and then a screen with an apple and a spinning wheel runs indefinitely. We let it run all night the first time and it stays on that screen for as long as you let it.

OS X :: Making Boot Image Using External Hard Drive?

Jul 15, 2009

I want to know, is there any specific way possible I can set up my external hard drive so that when I plug it in, it mounts as an image file? So say I have a file "Image.DMG" on my desktop, I want to make it so that my external hard drive "becomes" Image.DMG, so when I plug it in, that's what it mounts as. I would like to do this because I want to make a boot image using my external hard drive.

MacBook Pro :: Unable To Boot Off External Hard Drive?

May 4, 2012

Two years ago I installed Leopard on a pair of striped Fantom Hard Drives (3TBs) via Firewire 800, and have been running my 2007 Macbook Pro off it ever since. When Snow Leopard came out, I updated it with no problems. When Lion came out, again no problems. Last month I bought a CalDigit VR2 with dual hard drives (4TBs) specifically built for running OS externally. But no matter how I configure, install, or connect... it will not boot up my Macbook Pro, or my Macbook Air. 

Last week I bought a new Fantom external hard drive (1.5TBs) and discovered the same exact issue, with one exception... the Fantom will boot the Macbook Pro via USB 2.0, but only when plugged into the left side port.  

Has anyone else noticed this change?  

P.S. I've talked to the people at CalDigit, Fantom, and Apple, and no one seems to have an answer.

Info:
MacBook
Pro, Mac OS X (10.6.7)

OS X :: Snow Leopard Installed From External Hard Drive Won't Boot?

Feb 16, 2010

I have no id� whats wrong, I want to install Snow Leopard(from the external) on my Core2duo Macbook pro, which is running Leopard at the moment.

I have a Snow Leopard image, and I have used Disc utility to partition the external hard drive (GUID), and I assume the partition and install went well on the external, because in Disc start the external appears as OSX 10.6.

Then the problem: The macbook wont boot from the newly made external it just gives me this sign (of course without the colours).

I have tried to start the macbook normal, and with the option key held down were the external pops up.

I have also tried to chose the external in disc start and reboot with no luck.

I have tried to start the Snow Leopard install(external) within Leopard where the install start fine, but when it reboots and wants to continue the install, the sign appears.

The external harddrive is a 5400rpm 40gb 2,5" which is only powered by the usb port maybe thats the problem?

Software :: Boot / Reinstall System From External Hard Drive

Aug 16, 2010

I'm selling my old Powerbook G4. Before I let it go, I want to wipe the hard drive and reinstall OS 10.4. I also would like to run disk first aid because I suspect there may be some corruption. The problem: I still have the original system install DVDs that came with the laptop, but the DVD drive no longer works. It just spins the disks for a bit then spits them back out. I do have an external USB hard drive with plenty of free space. Is there a way I can copy the install DVDs (there's a Disc 1 and Disc 2) to the external hard drive, then boot from that drive and treat it like I'm installing from the DVDs? I also have my new MacBook Pro with a working DVD drive. Can I make my Powerbook boot from a CD in the MacBook's drive? If not, how else can I wipe my system and reinstall the OS without a working DVD drive?

I am currently using an external drive for my user storage.  Right now I log in with a separate User account to mount the drive, log off, and then log in with my user.  I am trying to remove the extra steps so I can boot my Mac and log right in.  I have not found any method that pertains specifically to Mavericks, and all of the methods I have tried for older OS versions do not seem to work properly.

Power Mac G5 :: Cannot Boot From DVDs - Defaults To External FW Boot Drive With 10.3.x

Dec 20, 2007

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

G5 Dual 2GHz

OS X :: How To Clon And Copy The Content From One An External Hard Drive To New Hard Drive

Oct 14, 2009

with cloning/copying the content one an external hard drive onto a new external hard drive. Basically, I have a 500GB FW400 drive which I use to store my media files. It's full, so I purchased a 1TB FW800 drive to replace it. Obviously, I thought I could simply copy and paste the media files from the old drive to the new one.I cannot copy the media files to my internal drive first as my internal drive is only 250GB and nearly full itself.I have used Disk Utility to attempt to close the old drive to the new drive, but keep getting "insufficient space" errors.

MacBook Pro :: Cloning Entire Hard Drive To An External Hard Drive

Mar 31, 2012

Recently I bought 2 identical WD Scorpio Blue 1TB hard drives for my macbook pro 13 inch 2010. My aim is to replace the internal hard drive with one of the two I just purchased and use it as my system drive with Lion, Windows and Data partitions. And for the other hard drive I want to use it as a full disk back up for the internal drive (now 1TB hard drive).After I was done with setting up both windows and mac and data transfer, when I booedt into the recovery partition from the internal drive to clone the drive to the external drive, the disk utility gave me this error (Could not validate source - error 254). I also tried using Carbon Copy Cloner but it only could clone partitions, not the entire drive. Yesterday I downloaded a copy of Clonezilla. It worked fine until it had to clone an exFAT partition (my data partition). The exFAT partition appeared as 'RAW' partition in clonezilla. As a result, the whole partition appeared to be full and clonezilla had to copy every single blocks of data in that partition and the estimated time remaining was about 30 hours. So clonezilla is out too. Just want to ask if there is any program/application (bootable or not) which allows can do a full disk clone to an external hard drive.

IMac PPC :: Make Hard Drive Into An External Hard Drive

Mar 1, 2012

I've had a lot of problems with my iMac G5 power supply and since I have newer computers I've decided to get rid of this computer. 

I want to save the hard drive and put it in a case, then use it as an external drive on my other Macs. 

What sort of case do I need to shop for? Should I look for SATA or what exactly is the proper nomenclature. 

Is USB 2 the preferred choice, or Firewire, or what? Is there a USB 3? I use a mid-2010 27 inch iMac with the intel processor, and I needed to buy an adapter to use my older Firewire external drive. Is Firewire a dodo?

PowerPC :: Hard Drive Spins And Super Drive Make Noise - No Boot Up

Jan 7, 2010

My friend gave me his old Apple cube G4 + 15" Cinema display in like 1000 pieces. Its completely teared apart. I tried a lot, but it doesn't work. The original IDE cable wasn't included, so I bought one for 2 cents. It should work or not? Maybe the powersupply. I'm not sure. I don't believe actually that the hardware itself, like the motherboard is broken. When everything is into place and I connect the cube to the powersupply it boots immediately. I don't have to do anything. Harddrive spins and the superdrive makes some noise as well. This repeats itself every 5 seconds. The screen is connected and gets power through DVI, but no display. Both the cube and display have touch enabled buttons to switch it on, but they do not respond (I guess).. Motherboard gives 2 light. DS1 is green, DS2 is red.

Mac Pro :: Internal External Hard Vs External Hard Drive

Looking for opinions or comparisons on performance between an internal mac hard drive vs an external firewire 800 hard drive or better. Is the performance on an internal MP drive or iMac internal drive much faster than connecting to a firewire 800 drive? I'm sure it depends on the drive, I'm wondering about apple factory installed internal drive vs say a WD external firewire 800
