OS X Mavericks :: How To Encrypt Existing External Disk
Aug 30, 2014
I have two G-Raid Thunderbolt RAID disks. Each is set up as a RAID 1 stripe (2 disks into one volume). I have my system disk encrypted with filevault, and would like to enable full disk encryption for the external disks as well. I tried the "Right click on disk in finder, select encrypt" option, but after I enter my choice of PW, I just get the error:
"A partition, not a whole disk, is required for this operation." Is this possible? Preferably, without formatting my disks all over again and enabling the encrypted FS at that time?

Decided to encrypt my external backup drive. Instead, I essentially doubled my memory by duplicating my external hard drive and adding it to my MacBook. Now my startup disk is full and I'm stuck. I also have Time Machine but not sure how to restore (replace?) my Mac storage to what it was two hours ago.

I have a 1/3 full external drive that is currently formatted for MAC OS External.
I want to partition the drive in half and use the 2nd partition for Windows FAT32.
However, when I try to do this with Disk Utility it does not give me the FAT32 option.

I have a requirement to encrypt the whole of my boot drive and my mobile Time Machine backup drive that I shall be taking with me on travels. I know I can use FileVault, which will give me an encrypted disk image but I don't like the reliability of sparse images and need the whole of the boot drive to be encrypted. I have tried Truecrypt to encrypt the TM disk, but could not get Time Machine to see it. I've been looking at the Checkpoint Full Disk Encryption product. What I'm trying to find out is if I can encrypt a USB HD with it, but seem to be going round in loops between Checkpoint and resellers.

I want to use TrueCrypt to encrypt an external drive. I understand the new version of FileVault can do this but I prefer not to upgrade to Lion. I'd rather wait till Mountain Lion comes out later this year.
For those who have used both...Just wondering how TrueCrypt compares to FileVault in regards to encrypting an external drive. Also, I am trying to install or execute the PGP Signature to ensure that the TrueCrypt software that I am downloading from the TrueCrypt's Web site is authentic and has not been hacked.
How do I run or install it? I double-click on the PGP Signature file, a window pops up and says it cannot find an application to open it. I even tried removing the ".sig" from the end of the file name and it say it cannot open the disk image.
There are instructions on the TrueCrypt web site for Windows users but none for the Mac users that I can see.

recently - perhaps after upgrading to 10.9.3 - I am experiencing kernel panics on my 15" MacBook Pro 2,3 GHz Intel Core i7 whenever I connect my external Western Digital My Book Essential hard drive. I have upgraded its firmware to the latest version I could find, v. 1025 - and thought this had fixed it, but it hasn't...

I wish to change partition scheme, sizes, in an external drive. All the partitions are MacOS extended (Journaled) and they map, according to the layout in Disk Utility, as follows: Partion 1, 2, 3,4 where 1 is at the top and 4, the bottom. I want to make partition 2 larger, so I decreased partition 1 by half. Now the layout is 1 a, 1b, 2,3,4., where 1b is now free space. Disk Utility will not allow me to increase the size of partition 2 by dragging the corner. Which of the following options (if any) will allow me to increase the size of partition 2, without erasing the data, using Disk Utility:Select partition 2 and manually writing a new value in the size box, equal to the present partition’s size plus the free space?If I delete partition 1 completely, will I then be able to increase the size of partition 2?If I delete partitions 1, 3, and 4, will I then be allowed to increase the size of partion 2?Is there another option?
(Actually, partition 3 is an eDrive, a data recovery utility created by TechTool Pro 7, so I don’t really know how it’s formatted.)

I'm looking for a good, reasonably priced, external disk to temporarily use for Time Machine backups. My 10.9.4 install is messed up and Time Machine no longer works with my ReadyNAS NV+ system. I want to use the disk to backup my MBP and reinstall the OS. suggest a proven external disk (2TB+) with a USB 2.0 (or Ethernet) interface?

Time Machine reported it failed backup due to the shortage of disk space. But I see the total space of partition is 192GB，the whole backup snapshot estimated is 177.56G.
The massage said that " failed backup, 52.85 GB is needed for backup but it's only 25.17 GB available."
I know it's 166.35GB of ancient snapshot still exist, but why not OSX to delete it automatically and release more space for new snapshot?
By the way, I can't delete those ancient snapshot in Finder manually, perhaps permission denied.

I have a new iMac using OS 10.9.4. I got an external HD for backup purposes and successfully formatted it. Now I want to create partitions; however, my Disk Utilities app does not contain any tab or command for creating partitions. Where should I be looking?

Having had an issue with 2 powercuts in quick succession meaning my Mac Pro was unbootable I am looking into the software RAID built into Snow Leopard. I know it doesn't replace backups and I got my data back ok from backups. My system disk is a 1GB drive, could I purchase a 2nd identical drive and mirror across that without having to do a system re-install? What would happen to the Bootcamp partition which is also on the same drive. Taking my thoughts one step further, if I bought 3 more 1TB drives, could I create software mirror sets, and then stripe across those, which should give me some performance and reliability gains?

I would like to use FileVault to encrypt both my hard drive and time machine back up external drive. Does encryption noticeable slow down the computer.

What can be done if Time Machine failed to save certain data to external hard disk, but I do have the old hard drive? I have a new IMac 10.9.2. The old IMac was hit by lightning/surge. Restored data from external LaCie disk but some information is missing. Apparently Time Machine did not save it to the external disk, or we just can't locate it. We do haves the old hard disk and will put it in a box to be able to access it.
Is partitioning the answer?

I have a 250 GB external I've been using for Time Machine since late 2007. I happened to check it today and it was nearly full~so I'm in that process of deleting some of the older data (that process is taking forever).
I would like to partition this external and use some space for iPhoto since my main HD is getting full. Is this a fool's mission? I can understand if I started from scratch but with a nearly full one is it possible?
I do have backup off site (Carbonite)~~maybe it would be easier to erase the external and start fresh?

I do like the concept of wireless routing/networking capabilities and integrated design of using Time Capsule w my new iMac 1tb HD (STILL not here yet), but am wondering if my 240gb WD HD is sufficient backup storage for the time being.
Maybe I can just spend the $300 for 500GB Time Capsule later on? Or should I just spend the $$$ and stop my sniveling? Once my iMac is delivered, should I take it to the Apple store and have them set it up, or is the setup easy enough for a Windows refugee to handle?
Please give me your feedback regarding this matter. Understand that I really have no wireless networking experience. Anyone whose read my previous threads will further understand that I'm currently a Mac Noob (virgin), and any elementary additional help is greatly appreciated.

I have a Mac Mini connected to a Lacie external HD that houses all of my iTunes library. I've just bought a new iMac to replace the Mini and want to keep the iTunes library on the external, just point the new machine's iTunes to the existing library on the external.
How best to do that? I don't want to restore from TM because I want to start fresh from this Mac and there really isn't a lot to keep other than the iTunes (most of it is on the external). If I point to an existing location, I don't need to Consolidate, do I? Any risk of losing the library? Do I need to unlink the library on the existing Mac?

Okay here's the thing: I (not so long ago) copied my entire itunes library to my external hard drive. Now I have updated my itunes library on my powerbook, and want to make sure that I back up the new songs/albums I have. The problem with this is that I have always found that when I drag the itunes folder from my powerbook to the itunes folder on my external drive, it asks to 'replace the itunes music folder'. I don't want this as there are some albums that I have stored in my folder but not on my itunes library and still want to keep them stored.
Is there any way that I could just keep adding to the 'existing' itunes folder on my external drive?

I have a new AppleTV set up in my entertainment center on the other side of my house from my office, where my MacBook Pro is. Currently I have my U-verse gateway(which has a wireless router built in) in my home theater. The AppleTV is wired into the gateway. The signal from the gateway does not reach my office so I was able to hack a linksys router into a repeater bridge (different SSID as my U-verse setup). This allows me to stream my iTunes library, which is stored on an external HD (1.5tb) connected to my Mac, to my Apple TV.

As I have a MBP 17" and a MBA Ultimate 11.6" I have copied all data that I need onto a 1 TB external disk and made 4 partitions on it, one for each type of data ( movies/music, data , software etc etc ). 1. I want to password lock/encrypt it yet be able to access it from both laptops as regular data would be.2. I want to create a backup of the 1 TB disk above, on to another 1 TB external disk and make it encrypted/password protected also. Maybe follow the partition structure maybe not, thats not paramount.What's the best way (apart from .dmg file) to achieve this given the data on disk in point 1 will change often as I create/edit more files.

Macbook Pro running on OSX Mavericks is having problems.
Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do.
Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair?

I wanted to do a clean install and repartition my iMac running 10.8. It has 2 partitions. I booted from the recovery disk, went to Disk Utility and erased the two partitions. However, when I tried to change to a single partition got the error message "cannot unmount disk."

I have a MacBook Pro running Mavericks.
Recently I noticed that if I run Check Disk in Disk Utility, all the process works correctly but at the end it doesn't tell me that everything is correct (in green).
On the contrary, if I run it in recovery mode, (reboot w cmd-r), it works correctly to the end with the correct green result at the end.
