MacBook Pro :: Is There A Way To Clone A Dual-boot Hard Drive?

Nov 23, 2010

I recently bought a Macbook Pro with a 200gb hard drive. Right now I am running bootcamp dual-booting OSX 10.6.5 and Windows7 100gb partitions each. I just got done configuring everything and then my friend offered me a 500gb hard drive for $50 so of course I had to buy it.

I am wondering if it is possible for me to clone the hard drive I currently have to the new 500gb hard drive and then extend the partition sizes so I don't have to go through and reinstall everything on the Windows side again.

OS X :: Unable;e To Boot From Internal Hard Drive / Use Disk Warrior To Repair Disk?

Apr 11, 2010

I am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.

MacBook :: How To Connect External Hard Drive To MB Through Linksys Dual Router

Jun 12, 2009

I have a WD Mybook Essential Edition external hard drive that is dedicated to the Mac that I am trying to connect through USB to my Linksys router (WRT 610N).

I have spent no less than 14 hours on the phone with Linksys, can't get through to Western Digital, and Applecare tells me they don't work with PC hardware.

OS X V10.7 Lion :: Disk Utility Can't Repair Disk (1 Partition) On External Hard Drive

Apr 24, 2012

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper! 

Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'.  And it needs to be reformatted.  It's become a read only disk.  When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question.  I also noticed that there are a lot of files with "date created" being the same date in 1969!  These files may be letters I've written or photo's I added to that partition within the last few years. 

I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure.  Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive?  And how do I get the read-only files back to their original state.

MacBook Pro :: External Hard Drive - Disk Utility Can't Repair Disk

Jun 27, 2014

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:

Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.

Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. 

Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive? 

I have a Macbook PRO late 2011 running OS X Mavericks.

MacBook Air :: How To Clear Start Disk / Hard Drive Of Clutter

Nov 30, 2014

I have been trying to download the new Yosemite update and kept getting an error message regarding the download. When I finally figured out what was going on, it appears that I don't have very much room on my hard drive to allow Yosemite to download. As you can see, the large problem is found in the movies and other categories.This brings me to my question.

1.) How can I clear up the 'other' clutter effectively, despite not knowing what falls into the 'other' category?

2.) Without having an external hard drive, is there a way to transfer movie purchases from iTunes to either USB drives or something simple to free up some more space? I don't want to outright delete anything, as I'm afraid that I'd lose the purchase, and therefore, the money spent. However, I'm not opposed to getting an inexpensive external hard drive.

I don't have a CD drive--just 2 USB ports and 1 for a memory card, so hopefully that won't inhibit storage options.

MacBook Air, OS X Mavericks (10.9.5)

Intel Mac :: Won't Boot From Hard Drive Or Disk?

Apr 1, 2012

Gray screen and 'prohibited' logo appeared today without apparent reason.Forced a power down by holding power button. Restarted....eventually reached user login screen but froze again on login attempt after password entered.

Restrated again by forced power down but only got gray screen and spinning gear.

Have now spent many hours going through most conceivable options including...

following instructions on http://support.apple.com/kb/TS2570 re gray screen troubleshooting

have disconnected peripherals; reset smu, smc, and pram;

safe boot w shift key did nothing;  

safe boot shift+v produced a screen of text that got as far as com.apple.launchd 1

but then several lines of text appeared repeating twice eaxctly same, each headed by disk0s2: I/O error. with [ErrNo 5], then

dyld: Library not loaded:   and Reason: no suitable image found

final line ends with The System bootstrapper has crashed: Trace/BPT trap:5 

I have tried installing from the original install disk several times but holding C key or Option/Alt key or D key gets no response and I cannot get the install disk to eject either holding down mouse button, eject button 

I haven't done any recent upgrades or installed new software, no new peripherals attached.

Is this a dead hard drive or does someone have other suggestions that might work?

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?

IMac :: Blue Screen On Start Up / External Hard Drive?

Jan 19, 2010

I bought a Guardian MAXimus hard drive and it seemed to be working fine for the past few weeks. Now all of sudden when starting my Imac 27 I7 the grey screen takes a long time then it get stuck on the blue screen and stays like that. Some times after being on the blue screen it will goto the main page but it takes 3-5 min if it does. When it gets stuck, if I unplug the firewire from the back of the computer from the hard drive it boots up. Any thoughts, their tech support wants me to send the unit back with out doing any testing at home to see what the problem is, seems like a pain in the butt.

MacBook Pro :: Adding A Old PC Hard Disk Drive As An External Drive?

May 6, 2012

So around 5 years ago i got the WD-160JB hard disk drive. I want to see all the things i did back then. I want to be able to connect this WD-160JB drive as a external hard drive to my mac. 

What i am wondering is if you can somehow have a cable or something which links the USB from the MBP to the hard disk.

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.

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?

OS X :: IMac Won't Start Up - Error Message Saying External Hard Drive Could Not Read

Feb 7, 2010

Ok so I have an 8800 GS imac, 3.06 intel core 2, 4 gigs ram. Running snow lepord. I need to resolve an issue where I can not get into OSX. At first I got error messeges saying my external HDD could not read, now it looks like its my primary drive because when I restarted I got the progress bar under the apple logo, indicating that something is wrong with the OS. The bar when to full 100% but then I got stuck at never ending spinning wheel. I restarted and no more progress bar but still the spining wheel of death. I really dont mind refomrating its just that I had some important text documents and other files that I cant get back without recoving them some how. How to proceed? I held down cmd v or s (i forgot) on startup and got a black screen with several problem statements. One reads the system boot strapper has crashed trace BPT trap.

PowerPC :: G4 MDD Dual 1 GHz - Start Up Disk?

Dec 13, 2007

I recently lost my G4 MDD 1.25 GHz tower to a power surge. I've replaced it with a G4 MDD dual 1 GHz. This is a dual boot machine. When booted up in 10.4.11 I can select the 9.2.2 disk but it will restart on 10.4.11 - Selecting Target Mode, it will boot on 10.4.11. The only way to boot 9.2.2 is with an Option start. When in 9.2.2 and using the Start up Disk control panel and choosing 9.2.2 - it boots up from the 10.4.11 disk. Additionally, when a Tiger DVD is inserted and the Install and Restart are clicked - it boots up the 10.4.11 disk.

I installed 10.4.11 and 9.2.2 on two partitions of another hard drive - same results. I Reset-all in Open Firmware. Pressed the PMU reset. I'm out of ideas.

I really hope I'm not the only one to experience this.

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.

Pro, Mac OS X (10.6.7)
