I was doing a 7-Pass Erase of a hard drive that I had switched out of my MBP. During the process, the USB cable connecting my hard drive to my MBP got disconnected. Now, whenever I connect this external drive to my MBP, it doesn't show up in the desktop or under disk utiltiy. How can I can continue the process of erasing and formatting the drive? What do I have to do in order for OS X to recognize it?

OS X :: Disk Utility - Formatting A Partition Without Erasing The Whole Drive?

Mar 31, 2009

I've been backing up my Powerbook G4 for a few months using Time Machine to an external firewire drive with two partitions; one for the backups, and a much larger one for all my music, video, pictures, etc. I got a new mac mini over the weekend and I want to format the Time Machine partition without erasing the one with all my other files so I can start backing up the Mini.

Is this possible using Disk Utility? If so, how?

Both computers are running Leopard.

Hardware :: Format External Hard Drive To FAT32 / Formatting Without Erasing Data?

Jan 19, 2008

I have an external hard drive that I was previously using on PC, having attempted to use it on a Mac, it will not write to it. I've found that I have to format to FAT32, which I think i can just about manage (yes, im a girl) but my concern is, if i format through the MAC, will i then lose what's on the hard disk as the tab says 'erase'? I have a lot of images on the hard disk so am a little petrified! Any advice for this really basic question would be appreciated!

Intel Mac :: Install A New System Folder Without Erasing The Drive?

Apr 29, 2012

I shut off my iMac the other day and now when it boots I get a start up bar that looks like on my iPhone when uploading new os. And then it gets half way and starts over. It seems that my hard drive has an issue.  I tried booting from snow leopard DVD. But I can't remember how to install a new system folder without erasing the drive. I tried making a bootable DVD of tech tool pro on a friends windows machine but it doesn't seem to work.

Intel Mac :: Formatting And Partitioning External HDD

Mar 11, 2012

Still new to iMAC (1TB). I have an external HDD 1.5TB and initiated TimeMachine (seems easy and fit for purpose) to keep a backup of everything on the iMAC. The iMAC did not come with an installation disc - apparently I would need to download the OS again should it fail or corrupt - unfortunately I have a VERY slow net connection - is there any way of backing it up to the external HDD to avoid having to download?

I believe I can purchase a copy of Lion in a flash drive - but I have already paid for Lion when I bought the machine? Would cloning sort this issue? If so - should I put the clone (Using something like CCC) in a separate partition? Have come across Recovery Agent - does it need to go in a separate partition? Finally - for now (!!) if I have to create any new partitions on the external HDD will it erase existing files, meaning I have to restart Time Machine?

Hardware :: Erasing Sparsebundle On TC?

Apr 30, 2009

My iMac gives an error when trying to backup, so I'm trying to erase the sparsebundle and start over. Every time I try, i get an error saying "The operation cannot be completed because the item 'bands' is in use."

Any ideas on what "bands" is and how I can erase the TC? Is there a way to restore to factory settings instead of trying to erase the sparsebundles? (plural because I back up both my MB and iMac on it.

Hardware :: Erasing An External HDD Partition?

Oct 22, 2010

I have an External 1 TB HDD where 250 GB of it is dedicated to Time Machine back-ups. I only have about 25 GB of space left but Time Machine won't update .. says there's not enough space. I thought that TM auto-deletes the oldest entry? Well it's not working. What should I do? Do I need to do into Disk Utility and just highlight my TM Partition and erase it then start over? There's nothing on it that I need.

OS X :: Partitioning An External Drive Without Erasing

Nov 3, 2007

In the effort to use Time Machine, I want to partition my external drive. I have 500 gig external, and would like to have one partition of 480 and one around 20. This way, Time Machine will only back up onto the smaller partition, not endlessly backing up until all 500 gigs are used. The reason I need to partition without erasing is my 170 gig iTunes library. Its too large to transfer to my internal HD, and I have no other drive to store it on.

I have royally screwed up! I want to erase the hard drive on my Power Mac G4 to prepare it to go to my son. I thought I was doing it right, but had forgotten to put the energy saver on "never turn off" so the screen dims when I try to continue with the erasing.

OS X V10.7 Lion :: Can Reinstall It Without Erasing Disk

Apr 27, 2012

I did the upgrade from Snow Leopard to Lion.  I've been having random issues like it seems to go to sleep (all monitors go black) and when I close the lid; the light goes on (but doesn't blink like normal sleep).  Or during wake-up from sleep, after everything appears, it does the same thing.  The only thing I can do it hold down the power button, wait, and restart.  Today I'm on my 4 1/2 crash/reboot.  (.5 because during a reboot, it locked up again.) I was thinking that maybe a re-install might fix something, but I'm not sure. When I originally did the upgrade, I had a DisplayLink driver installed which Lion moved to the Unsupported folder; don't know if this is part of my problem or not.

OS X Mavericks :: Restoring After Erasing Disk

Jun 2, 2014

I tried to install Mavericks and it told me my disk had been damaged and needed to be repaired. I took it into the Genius bar, he wiped my disk and told me when I got home to plug in my backup harddrive and click restore and it should be resolved. But I did the restore, created a new profile and everything and I can find my backup folder because my harddrive is plugged in, but don't know how to get everything from that folder back onto the computer, and back in its rightful place. i.e. pictures back in iPhoto, songs back in iTunes
