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.

I am looking at the WD MyBook Studio Edition II 2 TB and have some questions I need answered before getting it. Perhaps someone who uses it with their mac knows the answers.I want to use it with the RAID1 configuration. As I understand it it will then be seen as a 1 TB drive to the operating system, and the 1 TB data will be mirrored on the dual 1 TB drives.1) Can the 1 TB RAID1 drive be partitioned into multiple logical partitions?2) Can the 1 TB RAID1 drive be formatted as NTFS?3) Can the 1 TB RAID1 drive be partitioned into multiple logical partitions formatted with different file systems?

if i am running my new lion OS on drive #1 and i have a Raid1 array on drive #3 and #4 with all my DATA - can i back this up using Time Machine? i would like to place my OS's on a single drive and have my DATA in a raid array but if this means that i lose the ability to retain a Time Machine backup of my data i will simply upgrade to Lion and keep the data on this drive so it can continue to get backed up in time.Â

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).
anyone out there tried this? satisfied with the performance and reliability? happy with the choice of western digital over seagate over?

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.

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?

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..

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?

My dad recently brought a MacBook Pro but I get the chance to steal this to take to clients. What I would like to do is to use my license for software I use on both the laptop & my machine, can I duplicate the user or migrate the user to the laptop & sync the info when in the same wifi location of my iMac. I know there is iDisk but I'm not paying for that service. I would like to mirror my iMac desktop on the laptop. I'm sure this can be done.

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.Â
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.

MacBook Pro, Mac OS X (10.7.3)

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.Â
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?Â

I have iTunes and iPhoto libraries on my MBP that I would like to mirror to my external/Airport HDD so that my Mac mini can access the content.
I've been using iTunes sharing function, but it doesn't sync ratings/play count/etc, and iPhoto doesn't seem to have the option.

My goal is very simple for the time being.... run my 2 LCD monitors together so I can have double the desktop space. I plugged everything in properly and it seemed to work right away at my pleasure. However, then I quickly started getting real pissed off.. If you guys have ever looked into the "displays" option when you have a mac hooked up to any other kind of external monitor, there is a "mirror displays" option. When I have these 2 monitors running default mirrored, and go into "Displays" there is no option for unchecking the mirroring box. In fact, there isn't even the "Arrangement" tab. Just "Display" and "Color".

We've been reading a lot about trying to find the fastest 1 TB hard drive, with the Samsungs getting a lot of attention. My question is a little different... Do we have any good data yet on what the most reliable hard drives are? I realize that all will fail at some point, but are some less likely to do so than others? I'm currently trying to set up a RAID storage archive.

I have 2 1TB drives coming in on Monday, and I plan to put them in a mirror RAID using Disk Utility. How reliable is the OS X software RAID setup? Would I be better to just manually backup from one drive to another? The drives will be for my photography, I wanted a mirror setup so I'd finally have a backup of my (current) 250GB's of photos. (Most of which I could probably burn to DVD's but humor me.)
If the RAID crashed somehow via the software, would the data still be recoverable? I have a MP and will be putting them in Bays 3 & 4. Also, is there any benefit to the different block sizes? Since my files will all be at least 7MB would the biggest block size speed it up?

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 have a new (6 months old) 27in iMac with a 1TB disk and 8GB of memory. It is an Intel. I bought a new 1.5TB external USB HDD yesterday and formatted using the Disk Utility and tried both "Options" of "GUID Partition Table" and then "Apple Partition Map" because the backup kept crashing. I have selected only the main HD partition which is 55GB. I believe that it should work, however, for some reason unbeknown to me it keeps crashing. Initially, it was around about the 700mb or 1gb size. Then I managed to get to just over 10GB. Most annoying as anybody who has tried to backup with Time Machine must know given its slowness. The error messages say that the disk has been removed during the process which is not the case. Can anybody suggest a remedy or some other more reliable software to backup my system please?
Can anybody advise me as well as to whether either of the following are better than Time Machine Please.

My 8 core Mac Pro should be here in a few days and I have not spent much time considering a backup strategy. I want to keep it simple and reliable. I am not sure what size drives I am going to get. I will not be doing a lot of graphics work on the system. I will be using it for everyday business productivity, iPod music storage, and application development. I will also be using Fusion 2 with a Vista Home Premium VM. ON my current PC, I am using less than 100GB. I suspect 750GB will give me plenty of headroom. My first thought is to setup a three drive system using software RAID 1 (mirroring) with Time Machine using the third drive.
I know hardware RAID 1 is faster, but I don't think software RAID 1 will stress my Mac Pro too much. I would like to do this with all drives internal. Will Time Machine support that? If I don't think I am going to come close to filling up the 750GB array, do I really need to get a bigger drive for Time Machine? I am not looking for the highest availability possible or the most data security possible. I just want to make sure that I have a reasonably solid strategy that will keep me up and running through a single drive failure and allow me access to older files that I may have deleted for whatever reason.

So I just replaced my drive with an SSD. I'll post a topic about that later, but for now I want to limit this discussion to the migration from drive to drive. I should have just gone with the cloning approach from the beginning, but I was curious to try out a time machine recovery. So before performing the upgrade, I made sure that my Time Machine Drive had the most recent backups of everything. I swapped the drives and installed Leopard from the install DVD. When it prompted me to recover from time machine, I started the recovery. Everything finished successfully. When I rebooted the computer, some thing seemed a bit weird. My mouse sensitivity was different and my "stack" was showing the icons, instead of the folder like it usually does. I realized that I was no longer on 10.5.6. I was on 10.5.0, obviously. So I performed all the software updates. I restarted and there were a few more software updates. Updated those too. Okay now surely, I was good to go.
I was able to make my "stack" back into a folder and I could fix my mouse sensitivity (I think the reason why it went wonky was due to the addition of the trackpad pref pane in 10.5.6 and the lack of it in 10.5.0). Safari booted up fine. Then I clicked on Firefox. The icon bounced once, but no app. Weird... I figured maybe there was some sort of permissions error. I deleted firefox and reinstalled it. Same issue... Then I tried to start up Entourage. I got an error about not having proper permissions. I googled the issue and it looks like other people have had errors with Time Machine backups and Entourage..................

They'll pay most of that for the time being BUT in this economy and speeds getting faster almost every year, I'd be stuck with it. MOST I'd want to go is a year(carrier doesn't matter we get $50/mo. but goes to a person not a business) in case there's any changes in staff and being stuck paying it or having a 5 G or something a year in and pay to break it off.Basically it's to show off to clients how ads work at our company and how they can see there's other clients of ours have work for them that they can submit bids on. Usage is very light. Not a replacement for my broadband only on the road type of things. Questions:1. Is there reliable pre-paid 3G usb modems out there?2. Is there a cheaper way of doing this say, change out my sim card to the device from my Iphone? We're all ATT I know first gen (what I have) iphone allows me to use a crappy older cell when I go to the beach or anywhere it's too bulky or easier to break.
