OS X :: Best Way To Wipe Disk Without Using Startup Disk?

Jun 1, 2010

I've got an old powerbook g4 that I'm looking to sell, however before I do I want to clear everything off it. Unfortunately the disk drive is broken so I'm unable to erase disk using the installation disc which I know would be the easiest way... does anyone else know of an effective way to clear everything in this case? As I know that there will still be things left even after I've cleared all of my documents.

OS X :: Disk Warrior Unable To Replace Startup Disk / Connect To TC To Transfer Across DW's Preview

Feb 18, 2009

Yesterday I switched on my macbook (Leopard) and got the flashing question mark. Ran all the resets and booted with disk utility which encountered an 'Invalid B-tree Node' when attempting to repair the disk. Additionally, the SMART status was verified.

I ran DW 4 last night, and performed the hardware tests which reported that the disk was operating like normal. The majority of my media files and additional work is backed up to my Time Capsule but I still have a folder of papers that are relatively new, and wanted to retrieve. While DW managed to reconstruct the majority of my drive (there seemed to be 15g missing - but it's just music files) including this folder, it couldn't replace the disk, as it encountered 'Serious Disk Malfunctions'.

So, via the Disk Preview I want to transfer my saved folders to my TC, but I don't appear to be able to locate it (via ethernet) through DW - even if it's connected when I boot up in DW. So, first request is: Can I connect to my TC to transfer across in DW's preview?

Second is: What are my options if DW can't replace? Do I need to take it into Apple and get a new HD (it's out of warranty)? It's possibly worth noting that I'm a student and have absolutely no money - so cost effective options are a bonus!

MacBook Pro :: Folder With Question Mark At Startup - Disk 0 Showing In Disk Utility

Jun 24, 2014

I get this question mark along with a folder when starting up. I tried holding down the option key when turning on the power and then I get an internet recovery along with a globe. I click on the arrow below it and it takes maybe 15 minutes to start up. Then i get this disk utilities screen. I'm now unable to do anything. When going into disk utility, disk 0 shows with Mac OS X base system underneath it. All the clickable buttons are faded out. Is there something wrong with the hardrive? and where could i get this fixed? There isn't a warranty on it.

OS X Leopard :: Using Disk Utility / Verify And Repair Grayed Out, Using Startup Disk

I'm trying to repair my hard drive.

OS X :: Startup Disk Change?

Nov 29, 2009

I was attempting to gain access to an old external harddrive, so I downloaded a live CD. I changed the startup disk in the system preferences and restarted my computer. To my knowledge this was a one time change, meaning it would only target my DVD drive for one boot. So I used the live CD and I can't seem to eject it from my computer. Also, I can't force it to boot from my harddrive. I know keystrokes can initiate a different boot but nothing seems to work.
* While turning on the computer....
* option key
* C
* eject button
* Allowing the mac to boot into the live disk and attempting to eject the disk that way

OS X :: Cannot Use USB For Startup Disk - Tiger 10.4

Feb 20, 2009

I have this some what old Power Mac G5 rig here with a busted cd drive. Trying to upgrade it to leopard os x. Searched all over the place and found the best way to do this is to create an image file (.dmg) and restore it onto an external harddrive.. I have an 8gb microsd that I am using to do this via usb thumbdrive reader.

Now here is where the problem is..

When I go into Startup Disk on this desktop (Tiger) the USB simply does not show up! I cannot figure out why.. I've restored the USB using both APM (apple partition map) and GUID.. both still unable to be seen in the Startup Disk list of options.

Now, I take my USB with the leopard dvd install on it and plug it into my buddy's MacBookPro which is already running leopard.. I pull up startup disk and BAM, there it is! I was even able to boot into it like a normal install..

Does anyone have any idea why this is not working on my Desktop running Tiger?

MacBook :: Startup Disk Cannot Mount?

Sep 19, 2010

I was surfing this site a couple of days ago when my MacBook suddenly froze up. I couldn't Force-Quit anything or do a soft restart, so I decided to just power-cycle restart (pressing the power button until it shut down, then pressing it again to start up). When I did so, my startup disk wouldn't mount.

I should give you a little background: Mine is a MacBook White early 2009, with upgraded 4GB RAM & 500GB 5400rpm Fujitsu HDD. I took the HDD from an off-the-shelf 2.5" external HDD. It has served me well for slightly over a year, and is only now giving me this problem.

I have since replaced the original HDD (which I was keeping as a emergency backup, phew) and put the problem HDD in an external FW enclosure.

I have run Disk Utility on it to try & rectify the problem. Disk First Aid says the disk is fine, but I just couldn't get it to mount. I thought I'd try to erase it and restore from my TM backup, but after I erased the disk, it still couldn't mount. What's worse, now the disk is apparently not writeable, and I can't even erase it. Disk First Aid is still telling me the disk is fine.

I've also tried booting from my SL install disk, but it won't mount the disk to install SL. It is still visible in Disk Utility, but greyed out.

Can anyone advise what I can do to recover the disk?

I can't really bring it in for a warranty exchange, cos I ripped this disk out of the original enclosure, so the enclosure is now completely busted, and obviously the warranty won't be honored. (Buying the external was cheaper than buying just the internal, and Fujitsu had a pretty OK reputation for their harddisks at that point. Could you blame me?)

So any software or hardware (or combination) solution would be great. Worst case scenario is to get a new HDD, but I'd still like to recover the use of this disk somehow.

MacBook Pro :: Can't Check SSD As Startup Disk

Nov 9, 2010

I got an OCZ Vertex 2 120GB SSD and it runs fine and it's fast when using the computer. But the boot up time is so ridicules slow, slower then my old 500GB 7200RPM drive. My boot up time is around 37 sec with the SSD. The Apple logo came's up and the spinning wheel spinning forever!.

I think I know what the problem is, it's searching for like 25 sec for the first boot drive, and it can't find my SSD. Other people I know here on Macrumors just checked the SSD in the "Start up" in System Preferences and reboot, then they getting fast boot time. When I check my SSD and press reboot, it's still slow and when I later check the Start Up disk, none disk is selected (neither the SSD or "Network startup"...

Here is how it always look like when going in to System Preferences -> Startup Disk after a reboot, none is selected... (sorry for the Swedish language, I hope you will understand)

What should I do to fix this problem? (I've tried to reset NVRAM, PRAM and SMC, but with no luck).

OS X :: Easier Way To Clean Startup Disk?

Dec 4, 2008

So I've been getting the "Your startup disk is almost full" warning notice pretty frequently for about a couple months now, and I just keep deleting files and applications. It's gotten to the point now that I have nothing else to do delete because I basically use most of the stuff I have on my computer, unless there is something I'm missing. I was thinking, there has to be an easier way to clean out your startup disk, I just don't know how.

OS X :: Mac Partition Not Recognized As Startup Disk

Jun 6, 2009

Not quite sure what happened, but somehow part of my OS X partition became corrupted and is no longer recognized as a startup disk. I ran techtool pro and tried to repair the volume from there without luck, then ran a Leopard install DVD and ran disk utility's repair disk twice (first time came back with an error, second it was able to complete and fix all issues). Where I'm currently at. I am able to view all of my files via Macdrive and my Bootcamp XP partition without issue and am currently backing up any files I hadn't previously backed up. My question is, will I have to do a full reinstall of OS X or is it possible to somehow activate the drive as a startup disk or diagnose where the problem lies and address it?

I am trying to install Windows 7 via bootcamp. I opened Bootcamp Assistant, and when i click continue, i get this popup.

"The startup disk cannot be partitioned or restored to a single partition" The startup disk must be formatted as a single mac OS Extented volume or already partitioned by boot camp assistant for installing windows.

OS X :: Startup Disk Full - Slowing Down Mac

May 5, 2010

I'm a fairly naive mac user and got my friend to instal my new harddrive.

It's big, with 320GB.

However, he set up a startupdisk partition, with a size of 20GB, called OSX.

For some reason this is now full and slowing down my MAC which is particularly annoying as I have college essays to submit very soon!

I've checked what is on my startupdisk and it is as follows:

Private 8GB
Applications 5GB
Library 3.5GB
System 2.3GB

I don't understand what this means but I have copied applications, library and system to my HD and tried to delete off startupdisk but it won't let me. say it is require by mac.

Software :: HD Won't Show On Startup Disk?

Nov 26, 2008

I have an Imac 17" intel core duo 1.86 Gz, 512Mb ram. I put a new Hd because the other one died. When I go to disk utility I can see the HD. I formatted it as Macintosh HD and mounted it, however when i try to intall the OS using the original disks, it says "Software can't be installed on this computer". When i click on startup disk, the only thing i see there is the Mac OS DVD and Network start up, but no Hd at all. Some say maybe i don't have the original install disks but someone at the mac store said that the HD is not mounting and thats why the software can't be installed. Holding the Option Key at startup, only shows the Mac OS DVD. Am confuse why i can see the HD in disk Utility but in startup disk there is nothing.
