Intel Mac :: How To Completely Reformat HD To Reinstall From Backup
Apr 6, 2012
I installed windows through bootcamp and partitioned my hard drive to about a 300Gb/600Gb windows and mac respectively. After a while i decided to remove the windows partition. As I was repartitioning the Hard Drive through disk utility my mac froze and went to a gray screen so I restarted it. Disk utility says that the process finished however it does not recognise the 300Gb I used for windows. i.e. Disk utility says there is one partition, and that the total capacity is about 1Tb.
However the spaced used and space available adds up to 600Gb, its like the mac thinks that it is repartitoned to just 1, but not allowing me to acces that 300Gb. so my question is how do i completely strip back the hard drive to basic factory settings (iv backed up all my data to an external drive) so I can reinstall the mac operating system and repair the drive to make use of its full capacity, then re install from my backed up external drive.

iMac, Mac OS X (10.7.3)

Someone has suggested that I reformat my system to help eliminate problems with my version update. I have an ibook G3 128+512 mg ram 900 mhz white case 12' It had a Mac osX 2.8 verion. I updated to Mac OS X 3.9. I have had problems ever since with firefox versions not working and crashing. I have not been able to use flash or adobe flash because they won;t load. Flash or adobe flash won't load on Safari, either. How do I a reformat. Will this erase my hard drive. Is this the same as a clean install.

Okay. So, Safari was giving me some trouble, right? So, I thought I would delete it and reinstall it. I never had a problem doing so before, right? So, why not? I did, and then, when I tried to reinstall it, it tells me I have a newer version already installed.

Yes it would be a wise move to just reinstall mac osx first however i do not plan on using it at all, this mac was given to me and i prefer to use windows, ive used windows perfectly in the past before.
Currently i only have access to a windows computer, an 8gb usb (for the win 7 installation), 4gb usb (using rEFIt) and the mac itself.

Time machine only backs up the changing files in Mac. I want to use Time machine so it can back up my drive completely. From my music to pictures, to Apps to settings. I have a Case sensitive structure and I am about to format it to a non-case sensitive. And I want to back up everything. Is time machine a program for me?

I'm running an iMac (one of the all-white, 1.83 GHz C2D machines, with 512MB RAM) and i've noticed in recent months it's become outrageously slow, i have no idea why but it's just horrendous.
I'd really like to start afresh with a clean install of Leopard, but only if it will make a difference. Currently i'm finding that even with 2 apps open (eg Mail and Safari) there is serious lag now and again, and sometimes things lock up completely. Is this just a bloated OSX install or signs the computer is dying?
Anyway, i have a 180GB backup drive currently used for Time Machine, but if i reinstall then restore from that drive, won't it just restore all the bloat?

My MPB is having issues (it doesn't actually go to sleep, so when i come to use it, the battery is totally drained) and i want to backup everything before I take it into AppleCare, but I'm worried about some of my programs...
for example: I have Senuti on my computer (0.50.01). When I downloaded it, it was a free program. Now, the version that is out cost around $18 (i think). The old version I am using works fine for me, and I downloaded it free and legally--I don't want the new version.

I just reinstalled my system on a new system drive and then used the migration assistant to transfer *only* the user accounts and not the settings or applications etc. I wanted (needed) to start relatively clean. The system after all of this is very similar to the original system (same apps, same users, mostly the same settings etc.) and I would like to continue using my old Time Machine back-up if I can, but when I start Time Machine it just wants to create a new back-up and won't recognize the older back-up. I've read up about what to do if you get a new TM disk or if your have your logic board replaced, but this situation seems different. I can't figure out what would appear different to TM about my "new" system.

I have a hard drive with bad blocks. I backup the data and various other part of the drive to the cloud. However, I want to make a backup of the entire disk but want to be able to access all the data individually as I want to transfer the data onto a new HD and the applications/fonts etc onto an SSD. Also, is it advisable to literally copy the contents of the Applications folder across to the new SSD drive or should they really be re-installed one by one (yikes!)?

I have an early 2006 iMac with the notorious GPU issues so after replacing it with a new Mac Mini it's time to sell the iMac for parts. I'm trying to reformat the hard drive with no success - I boot off of the original Mac OS X 10.4.4 CD, launch Disk Utility, but whenever I try to erase the disk or delete the partition the program freezes. I've even tried using GParted Live! CD to delete the partition and the same thing happens - whenever I assess it, it locks GParted as well! Funny thing is, I can still boot off of the hard drive just fine.I should mention that the hard drive has 10.5.8 installed - perhaps there's an incompatibility between Disk Utility 10.4 and the installed OS?

I got the fatal folder with with question mark and grinding sound of the hard drive when starting my 2008 Mac Pro this weekend. After some diagnostics it was obvious the Hard Drive is dead, of course its the main drive that runs the OS and all my apps. I am picking up a new drive today and was wondering the best approach to get it up and running again. Everying it is backed-up on my external drive through Time Machine. Since the drive is dead I can't use a copy cloner to the new drive. Would I install the the hardrive and start the Mac Pro to boot off the Leopard CD, intall that and then try to run the backup from Time Machine?

I purchased an external hard drive ( a Seagate 2 TB Expansion Desktop Drive) and was told by the MAC rep in the store to perform the following simple task to reformat the disk so I could drag and drop files from my iMAC and store them on the external hard drive:Â
1. Go to Disk Utility
2. Choose the External Hard Drive
3. Select Erase
4. Select MAC OS Extended (Journaled)
5. Click on Erase buttonÂ
Unfortunately when I do this, I get the following error: Disk erase Failed with Error: File system formatter failed? I have Mac OS X (10.5.8)...

Ok so I want to reinstall Windows completely so what I did was I created a partition to store all the files that I wanted to keep - music, videos, etc.So if I reinstall Windows on the essential partition, the C: drive, and afterwards I move all my movies, videos, etc. to the essential partition with the newly reinstalled Windows 7, and deleted the partition I used to store the music and videos while I reinstalled Windows, would I get that space back to the essential partition?

upgraded my from Leopard to Snow Leopard when it first came out, but for whatever reason my system has been running somewhat sluggishly since I upgraded (My Macbook Pro is more than capable of running either)
I want to do a clean install of Snow Leopard.
Could I just copy all of my music files, documents etc to my BootCamp partition, then reformat and install Snow Leopard on the other partition? Or does it wipe the entire drive?

My Macbook Pro hard drive failed. It is completely unrecoverable. I've purchased a replacement. How do I format the drive, install Lion and restore my system from my Time Machine backup? My Time Machine backup was created from a USB connection directly to my Macbook Pro. I have a Apple Lion USB Install Thumbdrive.
