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.

OS X :: Will Time Machine Backup Hard Drive Completely?

Dec 26, 2009

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?

Intel Mac :: External Hard Drive Reformat?

Jun 29, 2012

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: 

1. Go to Disk Utility

2. Choose the External Hard Drive

3. Select Erase

4. Select MAC OS Extended (Journaled)

5. Click on Erase button 

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)...

Intel Mac :: Completely Stuck After Replacing Hard Drive

Jun 23, 2012

I have an old (late 2006) 20" iMac. Problems started a few weeks ago - first the computer would freeze and crash. Eventually I started getting either a circle/slash sybol or the question mark folder every time I tried to reboot. Eventually I concluded that the hard drive had gone bad. So I bought a new 1TB Barracude from OWC and installed it following instruction found on [url]....

Now I can't do anything. I tried booting from a OSX 10.6 install disk, but the machine simply spits it out after about 30 seconds and gives me the "?" folder. So I got my hands on 10.4.5 Universal Install disk and tried that, thinking that maybe the older machine needed an older version to start from (sounds logical at least). Nothing. It doesn't spit that one out, but still ends up with the flashing "?" folder after a minute or two. I've tried holding down C on startup. Same result. I've also tried holding option to get the startup manager, but that doesn't work either. I just end up back at "?". I really hate "?"

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 :: External Hard Drive Or Reformat Old One?

Jan 18, 2010

On my vista / xp machines, I have several external hard drives, Seagate, WD, HP, and 1 enclosure kit which contains some old internal hard drive.I don't really need all these drives on my VISTA/XP machines, as I'm trying to migrate to MAC.

I mostly use my mac for photos & creating home movies. So backing up the priceless pictures of my kids is critical.Do I really need to buy a MAC based external hard drive? or can i simply reformat one of my old drives to use on my mac. I know macs have their own file system (as pc's have fat32&ntfs).

Will apple time machine work with a generic re-formatted external hard drive.I also notice their are fewer choices for MAC ready external hard drives ...less specials than PC based externals.

MacBook Pro :: How To Reformat Hard Drive (OS X 10.7.3)

Feb 16, 2012

How do you reformat a MacBook Pro (OS X 10.7.3) 2011s Hard drive? I already backed up all the files I wanted to save. But since I have the new Macbook pro 2011 (only a few months since I got it) it didn't come with an installation disc, but instead already came with all the applications. I'm wondering how to reformat the hard drive so it wipes out everything and I can start fresh and what would happen to all the applications?

Intel Mac :: How To Backup A Corrupted Hard Drive

Jul 3, 2012

My computer crashed when I was playing a DVD.  It is a 500g hard drive and is 250G full, mostly music, some movies, and photos. I have lots of email as well.  I have an old time machine backup but there were 3 months of unsaved data such as new movie downloads, ipad sync'ing, photos, and music I need to retrieve. I stopped running time machine because the external drive filled up and I was going to buy a new one. 

I was able to reinstall the OS again over the old one and login however the old login was saved as a backup and a new user name was created.  The permissions were all messed up and I could not reassign the old user name with the old programs and settings.  The computer then crashed again before I could back anything up.  Now if you try to reinstall the OS again the CD's crash and it wont finish.  If you try to boot with the CD you can go to the Utility section and see that the drive says it's failing.  I'm not sure how to back all the files. 

Is there a way to remove the corrupt drive and later mount it as an external drive to the new one?  I'm worried that I won't be able to back the files up if I connect a new external drive.

Intel Mac :: Cannot Find Hard Drive To Restore Backup

Apr 2, 2012

My iMac wouldn't boot. All it would do is come up to a utility screen.So, I opted to restore from a backup (I use Time Machine that does backups to an external drive connected to the fire-wire port). I select the date of the backup that I wanted to restore and went to the next screen. When it got to the next screen where you needed to select a destination drive... it didn't find any in the system (there was no drive to select).

I assumed the hard drive died so I bought a new one. I put that in this evening and when I tried to boot the machine and restore from a backup to the new internal drive... the same thing happened. It did not recognize the new hard drive I just installed.I replaced a 500 GB Western Digital hard drive with a 1 TB Western Digital hard drive.Now I'm thinking the original hard drive is still good.

IMac (Intel) :: No Space On Backup Hard Drive?

Dec 11, 2014

I am unable to move files from a 250 GB backup hard drive to a 1.0 TB b/c I keep getting the warning that isn’t enough space. Get Info says that 999.72 GB on it are in use. But the 1.0 TB was almost empty. If I add up the space of each of the 3 or 4 items on it, I get less than 20GB. What’s taking up the other 979 GB?For background, I now have iMac backed up with LaCie 2Big NAS system. The 250 GB is primarily to hold iPhoto Library and backup copies of original photos. the 250 GB is full. So I am trying to switch over from 250 to the 1.0 TB for photos. Moved a few smaller files over, but then could move no more. Thought of running disk utility to erase the 1.0 TB, but now I can’t move the few files on it back to 250 GB, but of error message that it too is full.I did run Repair Disk on 1.0TB before started trying to move files.

Intel Mac :: Random Hang Ups While Attempting To Backup External Hard Drive

Apr 4, 2012

I've had an external 1.5TB MyBook for around five years now and recently decided to backup/replace it with a 2.0TB MyBook. However I'm having a lot of trouble finding a simple, painless way to copy all my files from one to the other. The hard drive is simply an external host for my iTunes library, which contains nearly 140,000 files. Initially I tried copying the entirety of my Music folder over, but for some reason it hit a hang at 96.58GB/947.06GB and has never progressed. I then attempted to do smaller transfers and got about 1/4 of the way through my library doing so, but I've experienced more hangs along the way.

Can't cancel the copy operation once they occur, so they just sit there on my screen. I attempted to restart my computer but Finder won't allow me to shut down without first canceling the copy processes.All of the guides I have found on the internet, including the Apple website, seem to indicate that this is the only way to do things, which is beginning to really frustrate me since it also seems to be a method that doesn't work very well; in fact, it seems to succeed mostly by random chance. Is there something I could do to ensure this doesn't keep happening, preferably so that I could go back to my original idea of copying the entire folder over at once?

I have a Western Digital 500gig external hard drive (model wd5000c032) which I'd like to completely reformat to use with my macbook pro and Time Machine (running os 10).As it is now, my mac can only use 147 gigs, and often gives an error message saying it needs additional space to backup. It was previously used on a pc to hold pictures, but I doubt it used anything near 357 gigs for that.

IMac :: Unable To Recognize External Hard Drive / After Reformat

Jul 7, 2010

Yesterday I reformatted my Macintosh hard drive, partitioned it, installed Snow Leopard on one partition and Windows 7 on the other. I installed all the drivers for Windows 7 from the Snow Leopard disc.

When I plug in my 1TB Seagate external hardrive it's not showing up in Snow Leopard or Windows 7. Not even in Disk Utility. I tried plugging the external drive into my Windows laptop and a pop-up comes up saying "USB Device Not Recognised. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it." I think that this may just be because it's formatted to Mac OSX?

The hardrive had all of my photos, videos and music on so I hope it's salvageable. I find it hard to believe that the hard drive malfunctioned at the same time I reinstalled the software onto the iMac.

MacBook Pro :: How To Reformat An External Hard Drive After Time Machine

Feb 18, 2012

I have an external hard drive upon which I put movie files that I view through a Sony box (like the Roku box). I brought my MacBook in for a repair and connected the same external HD and used Time Machine to make a back up. It did reformat it in order to do so, but since the Sony box isn't a pc or mac I didn't think it would make a difference, but now the Sony box won't recognize HD. Is there a way to reformat it on my MacBook so that I can use it on the Sony box again, or do I need to reformat it with a Windows computer? I had no issues when transferring files only and using the Sony box.
