MacBook Pro :: Media Backup - Mirror - For Bigger Arrays?
Jan 6, 2010
At this point I wish I just got a MacPro instead, this wouldn't be a question. I have a new 17"uMBP, bought specifically to take advantage of eSATA through the expresscard slot. I do photography and video work. I bought the best possible card, the Sonnet Tempo dual eSATA, to offer highest transfer speed and because it's the newest technology. To accommodate my media I bought a OWC Mercury Elite Al-Pro 2TB RAID 0. It's great. I wish I got the Qx2 RAID 5 but it's a little pricey and expensive to upgrade, but at least it has redundancy. I need to have a reliable backup solution. Drobo is expandable but I've seen so many poor reviews. I could buy another Al-Pro 2TB RAID 0 and connect them both and do a software RAID 1 with them. Or I could buy a cheap 2TB eSATA external and do daily backups. I could also get a dock and fill up drives as needed. Is there really an advantage to mirroring other than if my drive fails in the middle of a job? Wouldn't the software RAID needlessly slow down my system? Even if I did get the Qx2 RAID 5 it is bad to rely on such a system by itself to both store and backup my media or is it in itself a very reliable solution?

Alright, so this is what I have and what I want to do... What is the best and easiest way to get this done...
I have two 1TB WD Blacks... One I want to use to store all my videos... The other I want to use to backup the first... What are my options? The stuff on this drive rarely changes, but there are times where I will burn several DVDs at a time to the drive... I do this in order to play them wirelessly through my AppleTV...
My main drive is backed up using the TimeCapsule.

I just did a zero delete on my computer and only have CS5 master suite and Lightroom on my computer now (MacBook Pro 2010). I have 2 external harddrives I'm using. Both are 1TB. I have the Master drive with everything on it, and I want to use the 2nd drive to keep an updated copy of everything. Then I have a 3rd Hard drive, that I want to backup the 2nd backup and keep that off site. What is the best way to go about this?

I made my windows partition too small. I use it mainly for games and didn't fully realize the size of games these days. I decided to use a 500gb hd that regrettably is USB. I kept windows on my mac but moved steam and all the games onto the hd. Now everything is slow to load (naturally) and it just isn't a great experience. What would I need to do to backup windows onto the hd, delete my partition, make a new bigger partition, then restore onto my mac?

So I recently "downgraded" from an octocore Mac Pro to a AluMacBook 2.4. All sadness aside, I'm loving the form factor, the portability and the light up keyboard. I have a series of questions related to my overflowing media library (as my Mac Pro was acting as my media server).
1. I've become attached to the idea of installing two disks into my MacBook by removing the optical drive. I've done the appropriate amount of research to determine feasibility (it IS indeed possible). But I wonder, could I RAID these disks together in a striped array (0?). I tried launching the RAID Utility on my MacBook and it says "it is not supported with this computer". I plan on maintaining a Time Capsule backup of the RAID as often as possible to minimize data loss should something happen.
2. The reason I'm looking to RAID is because my iTunes library is currently just a bit bigger than any 500GB disk I could fit into my MacBook. So as a "just in case" question, does anyone know if I can spread my iTunes library across multiple places? Say, for example, I want iTunes to manage all my "audio" files on my internal disk and all my "TV shows and movies" on an external or the other internal... is that possible?

I was inquiring as to buying a raid-6 array from a well known company. I received the following as part of a pre-sales discussion. I have never heard this before, but wanted to seek others opinions as it sounds just too bizarre to be true - I mean how can people run snow leopard server if this is the case and manage data? He is recommending Raid-0 arrays backed up to another raid-0 array nightly, fwiw. For the record, I'm looking at Atto hardware cards and mini-SAS 8 bay enclosures, not software raid. Text of interest:
"These days a drive failure isn't the most common means of losing data. What we see the most problems with is what's called data corruption. It's when the data stored on a drive becomes scrambled for one of several reasons. On a software based RAID 0 it's usually easily repaired with tools like Disk Warrior or Tech Tools Pro. When the problem occurs on a Hardware based RAID 5 or RAID 6 the parity can quickly become unreadable making the RAID unusable by the computer. There are no tools that can repair the corruption on a parity RAID once it reaches a certain point. The problem arises because the parity data is stored across all of the drives, and in the case of a RAID 6 it has 2 sets of parity stored on each drive making corruption a huge problem.
If everything is going correctly and your workflow is correct you shouldn't see much corruption. We do see a lot occurring when video is stored on drives, and at times software or OS updates cause corruption all by themselves. OSX is famous for the problem since 10.5 came out. One common way to create problems for yourself is dragging and dropping files from one location to another. When you drag and drop you do not get the whole file, some of the index is lost. Do this enough and you'll have a problem because it's cumulative. Try this; do a "Get Info" on a file and note the file size. Then drag that file to another location and do a "Get Info" on the destination file copy. You'll see that the new copy is smaller, it's lost some index data. Do this enough and the file can become unreadable and will have to be repaired. Do it enough on a parity RAID and you can make the file unreadable and irreparable."

Yesterday I bought a new Mac Pro. I absolutely LOVE it, and don't care if they replace it tomorrow. It is a terrific machine. I do want to set up two sepeate RAID arrays inside it, and could use a little help, as I've never done this before. I want to set up one array, of two large (say 1TB) drives in mirrored (RAID 1?) format for all my data. I want to set up another of two smaller (300GB) WD Velociraptor drives, which I already own, in striped (RAID 0?) format for the operating system, and my applications, as well as a bootcamp partition.
This is where it gets complicated for me. Much of my data is on one of the velociraptor drives in another computer. My question is, can I install the two new 1TB drives, set them up as RAID 1, using the original drive that came in the Mac Pro, move my data over from the old computer, then install the velociraptors, set up that RAID 0 array, and install the operating system. In other words, will the "new" operating system recognize the data raid array that I had created with the "old" operating system?
An easier question. When setting up the operating system on what will be my new RAID 0 array, do I just boot from the CD? and secondly, do I first set up the striped raid, and then install the operating system, and then the bootcamp partition? Or is there a different sequence to use.OK finally, when booting into windows through bootcamp, will windows be able to see the seperate data RAID array?l

As we discussed in other threads it could be particularly advantageous to use SSD RAID0 arrays for dual or even multiple booting. With a decent amount of striped SSDs the idea is to run all your operating systems and applications with high speed. At least that is the theory. To test the idea I have decided to use two Maxtor 160 GB HDD in a very basic dual RAID0 array configuration for booting OS X and Vista-64 in AHCI mode.
Here we go:
First thing I learned is that you have to partition the HDDs prior to building your array.
Second thing I learned is that you have to keep it all in HFS+ to make it work.
So now I have used disk utility to create two equal size partitions in HFS+ with GPT on both HDDs.
Next I fused the two lower partions together for a first RAID0 array named 2R-Leo. Format is still set to HFS+ and RAID0 mode is selected.
Then I fused the two upper partitions together for a second RAID0 array named 2R-Vista. Here format is also set to HFS+ and RAID0 mode is selected.
With that done I exited the disk utility to get a fresh start on it. I then entered disk utility again.

Don't know how to file a possible bug report. I checked my OS-X version and it is 10.5.8, maybe more recent versions have been fixed: Here is a cut & paste from the gfortran bugzilla site  [reply] [-]2012-06-04 02:38:12 UTC Calls to fortran subroutines that use large temporary arrays fill up 'idle memory' on the MAC-OSX, as can be seen with 'top' or the Mac 'activity monitor'. I found that I can get around this by using: call system('purge')  in the code to evoke the command line 'purge' from within the program before the 'return' statement for such subroutines to free the idle memory; but I was wondering whether something could be done more fundamentally at the compiler level to avoid this problem. Without such clearing of idle memory I used to hear lots of disk access being done to get around the small amount of free 'core' memory. Massive arrays would eat up many Gb of core memory by turning it to 'idle memory'. Maybe there is a compile time option that I do not know about. [reply] [-]Comment 12012-06-04 02:47:43 UTC This sounds more like a bug in the Mac OS X kernel/libc and how it handles memory allocation.

I recently changed the iTunes Media Folder default location to a different area on my drive. I waited a couple minutes and the files did not move. I was unaware you had to go into your settings and also select to consolodate files. Since the files didn't move I reselected my default location and kept trying to go back and forth a couple times. After letting it sit for a couple more minutes I noticed over 200 GB's of files were missing. I looked in each folder I tried to change the default Media Folder location to but they were not in either of them. I have also ran multiple system file recover programs and been unable to find them.Â

I have a mid-2010 Macbook Pro with the Nvidia 330m. Does using Mirror Displays require any less system resources (such as VRAM) than Dual Displays? I mean it shouldn't right (assuming that you use the same resolution for Mirror and Dual) because there is still content on both screens being written to the VRAM?

I recently acquired a new to me 2009 13" MBP. I want to mirror all the applications (essentially everything on the computer) from my 15" MBP to the 13". What would be the best way to do this, should I use carbon copy to mirror my computer onto the drive and pop it in the 13" or should I use a time machine backup of my 15" system on a new drive and put it in the 13"?

Has anyone run a 20 or 23" display with the Air? Ok? Closed or open case? Wireless keyboard and mouse, too?
And, general impressions about running photo programs like PS, Elements, Aperture (not video, I think I know the answer to that, but correct me...).
In other words, where does the Air hit the wall for reasonably fast digital photo work? 1.6 or is 1.8 really a difference maker for this?
I have a chance at a cheap Apple 20" alum monitor. If the Air can really handle moderate photo work and run a big screen well, that would give me a nice set-up to be sure.

I just got a new MacBook Pro and would like to mirror my current G5 desktop hard drive, so that I can keep all my applications like Photoshop and whatnot. Or do I have to mirror it at all? I'd actually prefer to partition the hard drive on my new laptop, which would make mirroring impossible. (as far as I understand.)
Can I just transfer my programs. If so, how? I no longer have key codes.

How would I go about this if I didn't want to do it myself? Could I get someone at the Apple store to do it for me? (if so how much would that set me back)
Also, I'm not too good with hardware and stuff like that, would it be easy to put a new and bigger HD in myself?

I have a Macbook pro 2010, Lion OS. It has been working good until I conected the computer to a TV. I´m conecting my computer, frecuently, to some televisions. The last time I did that the configuration of my screen changed a little bit. The screen looks bigger than my display and I can´t see the hole screen at the same time, I have to move the arrow with the trackpad in order to see some corner of the computer. I tried to fixed going to the display preferences

My next computer purchase will probably be a MacBook (or MacBook Pro) but I obviously want to be able to plug it into a better screen when I'm at my desk. I was wondering if anyone knows if it would be possible to use my current eMac as this screen?
I have heard that in the early iMacs the monitor was connected internally with a normal monitor lead - so you could open it up and connect a longer one. Does anyone know if this would be the case with an eMac?
Or any other way I might be able to do this?

I've got a 17" MacBook Pro on OSX 10.5.7 and a 15" TiBook on OSX 10.4.11.
Can I connect the TiBook to the MacBook Pro in such a way that I can use it to extend the screen? IE: main window on MBP and menus etc on Ti? If so how? Is it easy to switch back and forth on the Ti so I can get back to it's own screen easily?

All the tool bars are ways too small. It's painful to read. I know there're ways to work around this problem such as decreasing the screen resolution, or use the Zoom feature. These are only workaround solutions because decreasing screen resolution makes pictures look less sharp, and the Zoom feature is not that fun to have all the times on your screen. It looks like Apple should come up with a permanent fix, as it is clearly not acceptable fix. Hopefully some Genius will come up with an App that offers a better resolution.Â
