MacBook Pro :: USB3 External Drive Keeps Getting Booted
Apr 30, 2012I recently got a 750 GB WD 'My Passport' external backup drive (the USB3 version) and every time I plug it in, my MacBook Pro starts the spotlight process and then within 5 seconds kicks the drive off!
Then, it gives me the lecture dialogue of dismounting the drive correctly (via Finder for example), not to just pull the drive out of the USB port!

MacBook Pro :: Booted From USB Drive / Cannot Unmount Primary Drive To Erase
Aug 28, 2014I've been having problems booting into my OSX partition. At the time it started I wasn't using my Macbook Pro (Late 2009) very often so whenever I needed I just booted up into my BOOTCAMP partition. Anyways, I decided to finally stop being lazy and do a clean install. There's nothing on either partition of the same hard drive that I want. I put together a bootable USB drive and boot from it. From here I go to the Disk Utility and try to erase the entire drive. It gives me this error: URL....
Now, that's not a screenshot from my mac but its the exact same error. Anyways, I've tried to find something on point but I just can't. Some posts have stated that the hard drive is broken, but if that's the case why can I start up the BOOTCAMP partition of the exact same drive flawlessly? I can even manipulate files on the OSX partition from Windows 7.

OS X :: MacBook Disk Erase Failed While Booted From External HD
Aug 4, 2009I'm booted on a MacBook Pro from an external drive, and I want to erase the drive inside the MacBook using Disk Utility from the external. For some reason or another, it won't let me do this. When I click on the Erase tab (whether clicked on the disk itself or the volume "Macintosh HD") and try to erase it, it returns with the error:
Disk Erase failed
Disk Erase failed with the error: Could not unmount disk.
When I try to install an image onto the drive, I get a similar error, except it says "Operation not permitted." When I tried it while booted with an OS X DVD, it worked fine. As far as I know, I should be able to do this while booted from the external HD.
OS X V10.6 Snow Leopard :: Booted From Firewire External Disk, Internet Slow
Jun 22, 2012My iMac is currently being booted from external disk via Firewire 800. I have to do this until I receive new install disks from apple to resore my machine.
The computer is usable, however internet is very slow... I have other devides, windows machine, ipad, iphone and they all run okay.
It seems that because I have booted via the external disk..... internet is slow. Could this be as the OS is needed to refer to the external disk?

OS X V10.7 Lion :: Using Time Machine To Determine When I Installed Update?
Feb 22, 2012Does anyone know if there is a file I can look at on the system to determine what version of the OS is install? I'm no longer able to boot once I updated to 10.7.3 and I want to restore from Time Machine back to 10.7.2 but I don't remember the exact date that I did the update. I want to be able to look at the Time Machine backup files by attaching it to another machine in order to determine when I did the update and restore from that point.

OS X V10.7 Lion :: It Won't Get Past Grey Screen
May 25, 2012My Macbook Pro (2008) was upgraded to Lion 10.7.2 before I bought it used. It's always been slow and after a little while it won't boot up properly, it only gets as far as the apple logo with the spinning wheel underneath.I've have used Recovery HD and Disk Utility to repair/verify the hard drive and after the repair it still won't boot up past the apple logo. I downloaded OSX Lion 10.7.4 (client combo) update onto an external drive but I can't install the update when using Recovery HD. I've tried mounting the existing hard drive onto an external drive, but I get an error mesage immediately.
There are only a few folders I need to take from the existing hard drive in the Macbook Pro. What can I do to either access my hard drive or get it to boot up properly? I have a retail copy of a Snow Leopard DVD that I can use. I believe I might have saved Lion onto a DVD a while ago, but Apple seems to insist we intall by downloading the latest Lion? Basically I need to access the hard drive without erasing the data

OS X V10.7 Lion :: Install On An External Drive?
Mar 17, 2012I have read the discussions on making a bootable backup of Lion on external hard drive or a USB drive. I am not clear on whether I can purchase Lion from the App Store and have it download on an external drive so that my Macbook with 10.6.8 will remain as is. I want to test drive Lion before giving up Snow Leopard. I use SuperDuper and have a bootable Snow Leopoard on an external hard drive. Addendum: It looks like I may need to upgrade from 2GB of ram to 4GB before using Lion. My question still stands though.

Apr 15, 2012I have received 2 Panic Attack reports in the past 24 hours the first was obvious with the little black window message appearing in the middle of my screen the system was idle at the time with several internet window open and a exel workbook. The second occured overnight when I came to my Mac this morning the screen was black i.e. appeared to be asleep as normal I hit a key and nothing happened, I checked the machine and noted that indicator lights on a USB drive I had connected and this copnfirmed the machine was still on, I had my own panic attack! I did the reboot by turning the off switch off, and then restarted a report was displayed indicating a Panic Attack had occured i.e.
"Interval Since Last Panic Report: 2366911 sec

The report is gibberish to me I wish they would provide a clear indication in these reports to help the non tecky gain some level of understanding as to what may be the problem, that was a mini rant!

OS X V10.4 :: Have Tiger, Can Install Lion On An External Drive
Mar 5, 2012I have an iMac Intel Core 2 Duo running Tiger. What I would like to do is install Lion on an external hard drive and have the ability to boot up using either Tiger or Lion as the occasion arises. Reason being, I have some software apps that would no longer run on anything higher than Tiger and would require $1200 worth of upgrades. While I plan to eventually make such upgrades (and perhaps buy a new Mac to put it all on), for now I'm seeking an interim solution. In short, I want to take advantage of what Lion has to offer in the way of increased speed and flexibility (especially with internet surfing) while at the same time being able to boot up part of the time in Tiger to continue to run my older apps when needed. So, can it be done? Install Lion on an external HD? Or do I need to install Snow Leopard first, then upgrade to Lion? Or is none of this possible without buying a new computer and just keeping my old machine to run Tiger with the older apps?

OS X V10.7 Lion :: No External Drive Will Work Via Firewire
Mar 13, 2012I am having a heck of a time trying to get either a brand new Lacie d2 Quadra OR a G-Tech G-Drive (both 2TB desktop models) to work on my iMac via the Firewire port. Mac is running 10.7.3, 2.8ghz Intel Core Duo.
Both drives are brand new out of the box.
When I connected them using Firewire they look like they mount, but they are unusable. They won't unmount if I try to reformat. Get error messages if I try to reformat, verify or disk repair. Messages say something about not being able to read some information. Keep in mind there's nothing on the drives. I have tried getting them to work with Time Machine with no luck. A few times it would backup for several hours only to give an error message and crash. Something is clearly wrong when I use Firewire.
But when I connect using USB? Voila! No problems at all. Repair, formatting, storage, etc. all work fine.
What the heck is it with Firewire? I am dealing with slow transfer speeds for now, but I'd really like to have them connected via Firewire and off my USB ports.
I have zapped the PRAM and permission module to no avail. Not sure what else can be done.
Intel Mac :: Can't Boot From External Lion Drive
Mar 16, 2012I am unable to boot lion from an external drive on both a MacBook Pro mid-2009 and an iMac late 2008. Both have lion installed and I would like to boot from either a FW drive or USB key. I have reformatted both a FW drive and USB and set them to GUID and installed lion but I can only boot them to the Disk Utility App (drive shows up only as 'EFI Boot' when I hold option down).
The firmware is up to date and I also reset the PRAM. I am able to boot both computers from an external USB Snow Leopard drive.

OS X V10.7 Lion :: External Hard Drive Not On Desktop?
Mar 25, 2012I had a black screen of death moment and since then, I've had a few weird anomalies with my iMac. I ran disk repair while logged in, and it told me there was a problem. I restarted in restore mode, and when I repaired the drive, it found no problems. I don't believe it.
1. My external hard drives do not appear on the desktop. They are mounted, and I can see them when I open the finder and the disk utility, but they won't show up on the desktop like they used to. I have played with finder preferences shutting the option to see them off and on, but this doesn't change anything. Very strnage.
2. iTunes completely whacked out. It "restored" itself by magic. Now all the Date Added dates are March 23rd. All of my podcasts disappeared, and all my settings were reset. I have no idea what else I lost. I want to restore from a back up, but I don't know how to do just my iTunes.

OS X V10.7 Lion :: TM To Backup From An External SSD Boot Drive?
Mar 25, 2012I have just installed a 240GB LaCie Little Big Disk Thunderbold SSD as a boot drive for my 2011 iMac (which contains only the 7,200 prm HDD). This has improved read/write speeds dramatically. I have transferred all my data and applications to the external drive in order to see the full benefit of the SSD.
However, I had not considered Time Machine. I thought it would simply be a matter of identifying the external drive and then connecting to the Time Capsule. However, the external drive is not visible in Time Machine set up and I suspect there could be a good reason: that it is not possible.
OS X V10.7 Lion :: External Drive No Longer Bootable
Apr 8, 2012I installed a recovery copy of Lion on an external USB drive, and although it shows up as a potential startup disk in System Preferences, I can't boot from it. When I select it as the startup disk in System Preferences and reboot, I end up booting from the internal drive. When I hold down ALT when booting, I see the access light on the USB drive blink a few times, but it doesn't show up in the bootable volumes list.The following Knowledge Base article makes me think my problem is that I use the same volume for Time Machine backups: url...I suppose one option would be to partition the external drive, using one partition for backups and the other as a recovery drive. Would that work? Is that the only option?

OS X V10.7 Lion :: Cannot Copy Files To/from External Drive
May 10, 2012I run an iMac 3.06 Ghz Intel Core 2 Duo with 10.7.3 and I'm having some serious problems with an external drive. Some history first - I have a large iTunes library (~3Tb) of everytype of media which I stored on an external NAS (iomega StorCenter) with no problems - then this NAS started to report a drive error with imminent failure. I purchased a new DAS (Western Digital) drive and moved all my content from the NAS to the DAS and everything was ok. Then I started to get errors through iTunes about cannot find the file and cannot read the files - and then I couldn't access anything on the drive. At this time I thought this was a different problem because I was running preview Mountain Lion, or there was an actual fault with the disk. After investigation, and coughing out for Data Rescue 3 I found that somehow the entire file structure had been corrupted and all my files had been orphaned. So at this point I had one dying NAS drive and one DAS which wasn't usable and no space to recover any files to.
So - next step was to purchase another external drive (and returned the WD) - this time I went for a G-Raid 4Tb (non-thunderbolt) drive and I've been in the process of recovering files from backups and iTunes. I've had no problems until today when yet again I've started getting errors and now I have problems copying files to/from this G-Raid drive.
Technical details - OS-X 10.7.3 - G-Raid 4Tb formatted as Mac OS Extended (Journaled) - currently showing 1,163 folders and 15,452 files.
Symptoms - using finder drag and drop copy a file from the g-Raid to desktop results in 'The operation can't be completed because the item 'xxx' is in use. - 'The operation can't be completed because one or more required items can't be found (error code -43).' and the copy fails.
Using the cp command I get a 'Resource Busy' error. However, this is not for all files - I've managed to copy all my books back to the desktop ok, when a couple came up with the above error I tried again and it copied successfully.
I have run Disk Utility - here are the details :-

and it's just got worse - in getting the info for this post I no longer have access to the drive. This is the second time this has now happened on two different directly connected drives (USB and Firewire) - which means the problem is elswhere. I've a stack of errors in the system.log file

OS X V10.7 Lion :: Can't Boot From External Drive After Upgrade
Jun 5, 2012Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB). Tested booting from the external disk and it appeared to work correctly. Upgraded to Lion. Several days later attempted to boot from the external disk (by setting the start up disk in the system preferences) but it fails. The system always boots into Lion.
What I've tried: Setting the start up disk through system preferences. Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk. Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).
