Mac Pro :: Mirroring 3 HDs With 5 Partitions Onto One External?

Feb 25, 2008

I have three Hard Drives installed in my Mac Pro. The original one and two aftermarket. They total around 850 GiB. I have them divvied up into 5 partitions. If I wanted to Mirror them onto ONE external 1TiB Drive, what are my options? Is it a backup only type of thing, or are there options to do a real time mirror like RAID-1?

Intel Mac :: Screen Resolution Reduced When Mirroring External Display

May 14, 2012

I have a 2.93 GHz Intel Core 2 Duo (24" early 2009) iMac running OS 10.7.3 (Lion) to which I have connected an Apple Cinema Display as an external monitor using a Mini Display-to-DVI adapter.The iMac is set to 1920 x 1200 resolution and the Cinema Display is at 1680 x 1050, and everything looks great until I turn on mirroring. When I do this, the iMac screen loses its nice crisp screen resolution, but the Cinema Display still looks fine. Strangely, the pull down menu for displays in the menu bar still claims that the iMac is at 1920 x 1200 and the Cinema Display is at 1680 x 1050, but I don't think this is the case. Is there any way to keep the iMac at the higher resolution while mirroring?

I want to share one external drive with both my PC and Mac. I do not want to share the data. I want to use the PC partition to backup my Vista OS and want to use the Mac partition to backup my Mac OS. what is the best way to configure this?

I had created an NTFS partition using my Vista machine, but when I plugged in the external drive into my Mac and tried to create a Mac OS Extended partition, I lost my NTFS partion.

OS X :: Cannot Mount External RAID - Partitions Locked

May 25, 2009

I'm having a problem with my external RAID that I use between my G4 Laptop (10.5.x) and G4 tower (10.4.x). I downgraded the G4 laptop to 10.4.x so I can run Classic (kids educational software), and gain some speed. I backed everything up to my external RAID (two HD's RAID together). The downgrade install onto the laptop went perfectly. I went to restore some files from the RAID backup, and I got this error when trying to mount the external RAID: "the disk you inserted is not readable by this computer".

I just ignored the error and did not touch the RAID. I then re-connected the RAID to my G4 tower that had previously mounted successfully, and same error: "the disk you inserted is not readable by this computer". This time I started Disk Utility, and it sees the RAID and it's volume set, but it is "Locked" (see attached pics). I think I need to first mount it to change any "access control list" or permissions, but I can't figure out how to mount, and then change permissions/ACL.

OS X :: Why Doesn't Finder Show All Partitions Of External Hdd

Mar 14, 2010

I've used Seagate FreeAgent Pro 500 Gb. It has been divided into 2 partitions. one is used for time machine, another is used for keeping my important data. I think that the Finder should show both partitions on the left, but it shows only Time machine .

I regularly run software update. As I can remember, it has ever shown two partitions. I don't know whether this is related to software updating or not. If it is 'yes', how can I solve it?

OS X V10.7 Lion :: Partitioning An External 500 GB USB HDD (NTFS) In Two Partitions?

Jun 16, 2012

I realized Mac OS X 10.7.4 will only read NTFS partitions (can't write to it). I could install a third party driver or use FAT32. I decided to split the external Seagate HDD into two partitions (NTFS and Mac OS Extended FS).  

I went to Mac OS X's Disk Utility, but there was no way to partition the current single 500 GB NTFS partition with my existing data. It seems like I have to erase it with my data, and then partition into two. Is that how it supposed to work? This was on a new Mac Mini with all updates.

OS X Mavericks :: External Drive Partitions Inside Themselves?

Dec 1, 2014

I use a 250GB external HD for most of my working files. It has five equal partitions. In one of the partitions--Cedar Mill (see attached images) --another partition (CM News) shows up in Finder. Inside CM News is another copy of itself ad infinitum... 

I am reluctant to delete them without knowing what I'm doing. How they got this way. 

I haven't noticed any particular problems, except possibly slow search times for opening/finding files...

OS X :: Changing Partitions - Time Machine Will Be Reinstall If I Change My Partitions?

Mar 7, 2010

I have an iMac 2.4ghz with a 320g hd, that I partitioned 50/270 when I installed Leopard. I read somewhere to have the opp system partitioned and I have been kicking myself in the rear ever since. Too many apps and files want to run next to the opp system, so I'm starting over.I used time machine for a backup of the system (both partitions are showing) on my 1 TB iomega external hard drive (minimax). I partitioned the external 500/500, time machine/additional storage.So that is what I'm working with, now for the question:With my backup complete, if I do a clean install to the internal hard drive (320g) in order to remove the 50g opp/sys partition and just have one 320g internal hd; will my time machine be able to restore to a clean 320 without having the 50/270gig partition setup? If so will this be a somewhat simple process?

Hardware :: Using External Hard Drive Partitions And Formats?

Jan 27, 2009

I've just ordered a Seagate 500gb portable hard drive. I want it for backing up my 250gb Macbook, storing films and also for exchanging files between computers (Mac and Windows).

After reading various posts on the forums I'm planning on making 3 partitions:

1) 300gb for time machine backup. Mac OS X Extended (Is this the same format as HFS+ just a different name?)

2) 15gb for exchanging files. FAT32

3) The remainder for storing films. Mac OS X Extended.

Have i got these formats correct and are they suitable?

Also, i read that FAT32 is fragile and data can get wiped off it. If this did happen to the FAT32 partition, would it jsut affect that partition or could it damage data in all the partitions?

OS X :: External Hard Drive/Partitions/Time Machine

Jan 11, 2010

I have still another EHD/TM question and I can't quite figure out where to ask for the help I need.
I have a Mac Pro OS 10.5.8 with 2 internal drives and a large EHD that I was using solely for Time Machine Back Up. After a recent conversation with tech support at Apple, I've decided that I should have still one more full copy of stuff that is critical to me--my original photographs. I currently only have the backup copy on TM.

So, I want to take my large LaCie EHD and partition it. I want to store things as follows:
1. Internal HD #1-primary HD containing all data except original photos
2. Internal HD #2-HD that contains nothing but original photos
3. EHD (LaCie):
a. Partition #1: Second copy of original photos
b. Partition #2: Time Machine back up of HD #1 and HD #2.

It seems as if it is easy enough to do the partition but I'm wondering if there is a way to get my original photos to go into both HD #2 and Partition #1 of the EHD at the same time that I import them via a card reader.

If not, I'm wondering how I can set this up so that I don't have to remember to copy the photos from HD #2 to the EHD. Do I have to use another back up program? If so, any recommendations? Will using another program mess up Time Machine? What am I not thinking about?

MacBook Pro :: How To Rename External Hard Drive With Two Partitions

Jun 6, 2012

I have an external hard drive with 2 partitions: One for my video and music files (named jukebox) and another for time machine (named time machine). The external hard drive itself is a 1TB WD Elements. If I open up disk utility I can see the name "1TB WD Elements 1023" with 2 subpartitions as above named. Similarly when I plug it in to my playstation the drive is displayed as "USB WD Elements 1023". How do I change the name "1TB WD Elements 1023" to something else? I can find it in finder and I can seem to find any command to change it within disk utility. I really like to change it as I sometimes have another WD Elements drive plugged in to the playstation as well and they both have the same name which is confusing.

Windows On Mac :: Getting Windows To Recognize Partitions On External?

Mar 10, 2010

I have an external drive that I've been using for Time Machine backups and file storage. I had two partitions to do this (one for TM and another for files). That was pleasing until I bootcamped Windows 7 to my Mac. Now I would like to use another partition for Windows Backup and yet another for files since I gave Windows only 15 gb to work with (my internal HDD isn't very big). No problem, I thought.

My external HDD is 1TB so I just split the ridiculously large Time Machine partition in half and split the half in half. Voila! Four partitions on the drive! However, Windows would not recognize it. After searching around on the netz, I opened Disk Management (somewhere in the Control Panel's administrative tools). It asked me to initialize the disc. Wary, I searched the netz once again to find that this will likely erase my data. So I haven't done it.

My questions:
1. Will "initializing" the disc actually erase the data that is already on it?
2. Is there another way to get Windows 7 to recognize the drive (and the two pertaining partitions)?

Connection type: Firewire

i am seriously considering using a software mirrored pair (RAID 1) of 1TB WD RE3 drives as an osx home drive. boot drive will be a discrete disk. another drive for windows. full backups weekly to an external drive.

space-wise, this should last me a long time. (lived with a G5 2x2.5 for four years and recently upgraded to an 8x2.8).

OS X :: Screen Mirroring / Spanning?

May 16, 2008

I purchased a Mac Pro sometime back to use in my office but the person in the office next to me also frequently has use for a Mac Pro and since we can't purchase two Mac Pro's now we decided to set up a system with multiple monitors/keyboard/mouse. We ran a 2nd DVI Cable and a USB Hub over to the other office and use that for a second monitor hooked onto this Mac Pro plus a 2nd Keyboard and Mouse. Fortunately the distance was not too far and it worked out well.

we're having is trying to figure out how to do the Screen Mirroring/Spanning. The Mac Pro has two video cards. Video card 1 is the Nvidea 8800 GT and the 2nd card is an ATI 2600 XT. I have the main monitor in my office which is a 22" Samsung Widescreen hooked up as video 1 on the Nvidea card. The 2nd monitor which is an Acer 19" Widescreen monitor has been hooked up to both video 2 on the NVidea card and even video 1 on the ATI.

OS X :: Does Mirroring A Boot Drive Change ID

Dec 24, 2008

I'm planning on using SoftRAID to mirror my boot system drive. Softraid allows to ADD another mirrored drive (or more) to an already existing boot drive without the need to reformat anything. From what I've read, it seems this software works well. I don't have anymore PCI slots so a hardware RAID isn't an option for me.

So here are my questions:

1. After I add a mirror drive to my already existing boot drive, will this new configuration cause the volume ID to change, as if it were another drive? in other words, will I have to authorize a bunch of my plugins again because they will think I moved them to another system? Cloning a boot drive doesn't allow to use the same authorization for most plugins. Will the added mirrored drive have the same effect?

2. Say one of these drives fails, and after I replace the faulty drive with a new one, then the software rebuilds my mirror boot drive combo, will the ID change again, or will the current plugin auths still work?

I have so many plugins now, I can bear the idea of losing my boot drive because it takes me weeks to re-serialize my plugins. Half these plugin auths go by BOTH the drive ID AND the Logic Board ID, so reformatting or getting a new drive (or reverting to a previous system, clean reinstalling a system etc) is a nightmare for me. When my boot drive fails It's more worth the trouble for me to purchase another computer and gain the extra speed. I feel the mirrored boot drive is a great solution if I can keep replacing the drives when they fail, for a longer general system life... If the RAID keeps the same ID that is..

Hardware :: How To Get Security Of Mirroring Hdd Data

Jan 3, 2009

Mirroring basically creates a mirror image of any data on a drive as it's created (on the physically seperate mirrored drive)...the idea being that if the drive get's corrupted you will always have the mirrorred copy as a backup...

But what happens if it's not the actual drive that gets corrupted, but rather some of the data on the drive...then you would basically have a corrupted copy of the data on both the primary drive and the mirrored drive, correct?

OS X V10.7 Lion :: IMessages Not Mirroring Between Mac And IPhone

Feb 16, 2012

First I signed in with the wrong Apple ID. Now I'm actually logged into iCloud with the same Apple ID on both my Mac and my iPhone. Parenthetically, I would like to wonder out loud how synchronization of addresses, calendar items and notes ever happened before, with mismatched Apple IDs. 

The problem is that I don't see that the iMessages I send in Messages on the Mac are mirrored in Messages on my iPhone. It makes me wonder, whether this is beta behavior or whether I still don't have everything configured correctly.

OS X Mavericks :: Mirroring Folder On Two Macs?

Aug 26, 2014

I have a Macbook Pro and iMac on the same network.  I'd like folderX on the MBP to be basically mirrored on the iMac.  If the MBP goes down or I need to send it in for repairs, I want the iMac to always have an updated version of folderX so I can continue working on this content from the iMac.  Then when I get the MBP back, I'd like the MBP to be updated with latest changes from the iMac and then have the MBP once again become the primary and ship folderX updates to the iMac. 

I believe a Time Machine from the MBP to the iMac might work?  I do have a 2TB TimeCapsule and TM is in use on my MBP.  But can I only have 1 TM per computer?

OS X :: Software RAID1(Mirroring) On Leopard - How Reliable Is It

Nov 7, 2007

I just purchased OWC External HDD Enclosure that houses two HDDs. I've placed two WD 500GB drives in them and did a RAID1 array using Disk Utility in Leopard. Now I know Mirroring is meant to be like an insurance in case one of the drives failed, I would still have a copy of the data. How reliable and safe is OS X Leopard RAID1 software? This is my first venture into using RAID, and I just want to make sure I'm better off using Software RAID than keeping these two drives in separate volumes. The Data stored in them are my new nephew's/godson's baby pictures from the time he was 3 seconds old up till now. My sister has given this responsibility of keeping all the digital pictures and video safe, so I want to make sure I don't loose this Data.
