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.

OS X V10.7 Lion :: Enabling FileVault On An External Drive Without Erasing Its Data?

Jun 11, 2012

Since I activated FileVault 2 on my Mac boot drive without initializing it, I'd assume that the same thing could be done for any other drive. I've got some external drives with hundreds of GB of data which I'd like to encrypt. Disk Utility lets do it by erasing the drive and encrypting the data written afterwards.

Is there any hidden feature that allows one to convert the drive without erasing it first, like the FileVault utility did for the boot drive (even when working on it!)?

Info:
MacBook Pro, Mac OS X (10.7.4)

OS X :: Mac Install And Repartitioning Of HD

Aug 22, 2009

Do MAC users partition their hard drive much like what people do in windows? normally i do this in windows: (lets say a 500GB drive)

Drive C: (25GB) for OS
Drive D: (100GB) for Programs
Drive E: (375GB) for Files/Etc

Does this also hold true for MAC? If so, what would be the best partition allocation for a 500GB drive given that you would like to install windows as well. (not sure if ill be installing windows as dual boot or only call windows via vmware-is this right?)

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!

Windows On Mac :: Repartitioning Hard Drive Without Reinstalling 7?

Nov 16, 2009

I split my MacBook Pro into 130 GB for OSX and 100 GB for Windows 7. Although I do enjoy and use Windows 7 on my laptop often, I need more space on the OSX side for my media. At first I planned to keep it in an external My Passport drive and just connect it whenever I wanted to use my media, but I came to learn that that idea is a pain in the ass. So I would like to keep all of my media (mostly music) in the OSX partition. The thing is though, I have a Windows 7 desktop at home, and I installed windows 7 on my MacBook Pro only because I found it convenient to be able to work on Windows-only things when I'm not at home. So I really don't need that big of a partition on my MacBook for Windows. I figure, for my purposes about 50 GB is plenty. I already have a copy of all my media hooked up to my PC on an external harddrive at home anyway.

I would like to have all of my media wherever I carry my MacBook as well so I would like to adjust the partition to maybe just 50 GB for Windows and the rest for OSX. Is there any way to do this without having to reinstall Windows 7? I would really like to avoid the process of reinstalling Windows and all the programs I already have in it.

Hardware :: Erasing Sparsebundle On TC?

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.

Power Mac :: Erasing A Hard Drive On G4?

Mar 22, 2012

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. Tried to start over with an install disk in the tray. Now can't access the original disk.

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

Hardware :: Erasing / Renewing Airport Networks

Jul 24, 2010

2.8 GHz Intel Core 2 Duo iMac using OS 10.6.4. I'd like to renew/erase the Airport networks listed under the Airport logo at the top banner of my iMac. My hope is to re-install Airport Express and have a wireless network again. I have tried using Airport Utility but get no where with it. In a related question: do Airport Express devices wear out after being used for 2-3 years or are they bullet-proof? I'm wondering if that is my problem.

I was doing some cleanup on my macbook pro, deleting old log files and suddenly the system froze. I turned off and then on the laptop and to my surprise, the Mac partition doesn't show up on bootcamp menu, and I'm taken directly to Windows.I tried booting from the install disk and repairing the disk with Disk Utility, and although all my data seems to be all right (I can see all of it from Windows), and Disk Utility did not find any errors, when I reboot (while holding the option key) only Windows shows up.
