OS X Mavericks :: Why No RAID Options For New Disks
Nov 30, 2014
"My name is Shaun, and I am a mac-aholic"
I inserted 4 new 3TB disks into the bays of my Mac Pro (2012), and there is no RAID option for them.
How I got here:
Inserted the WD Red drives, and they were not initiated.
I "erased" the drives, gave them names, and they appear in Disk Utility in grey drives.
Went to set up the RAID, and move the drives into the RAID, but got an error that they could not be used.
It appears to me that disk utility is not allowing me to fully use those drives. I Have created RAID drives before with no issue in RAID1 with 3TB drives before on this machine. Am perplexed, I thought this to be the easy and simple part of my upgrade odyssey! Did I screw up the initialization? On all FOUR drives?
Now, if I click on the drives, the RAID option does not present itself.
FWIW, I am using OS X 10.9.5, on Mac Pro 5,1. I boot from PCIe card. My end goal is to create a 4-disk RAID 10 using the four SATA connections on the MP.

So, please welcome me back. After 15 years (I had Mac Plus, LC and Quadra 650), I am back from the darkside. Bought myself a Mac Pro today. Yeah - I probably should have waited for nehalem, but my PC was getting flaky. Time for the every 9 month wipe/reload and I just didn't want to go through that again, so I jumped. Tomorrow I am moving drives into the MP. My questions is specifically about partitioning and Raid. I typically partition my drives about 1/2 way down the middle and give the 1st partition to high performance needs and leave the second for infrequent use of backups and storage.
Lets assume I have two WD6400AAKS (I have three actually). Ideally, I'd like to partition them like this:
WD1 Partition 1A (200GB) Partition 1B (400GB)
WD2 Partition 2A (200GB) Partition 2B (400GB)
Then (using Soft Raid)
- Config partition 1A and 2A as Raid 0 Striped (giving me 400GB high performance)
- And config partition 1B and 2B as Raid 1 Mirrored (giving me 400GB redundant backup)
(Yes - of course I don't want to access the mirrored drives when expecting high performance from the striped drives). I assume that once the drives are partitioned, the Soft Raid will simply see them as four different drives allowing me to configure them as described. But before dropping a few hours into this, I thought I'd let all you raid/hard drive experts give your opinion.

I have a hex with 4x 2tb istalled on regular Mac bays and one ssd on the optical bay. They(4x 2tb) are configured as a giant 8tb JBOD. Now I purchased 3x 3tb and a sata card for the extra sata ports. Is there a way to create another JBOD with the the new 3tb drives and in the near future get rid of 2tb ones and put the 3x 3tbs on the regular Mac ports without loosing the data. All JBOD will be and was created using Snow Leopard's disk utility.

I have a Early 2008 Mac Pro. I have the Apple Hardware Raid Card Installed. I have 4 2TB disks installed. Currently I've got the system disk setup in Bay 1 as a single disk. Then I have the disks in bays 2 through 4 setup as a raid 5. I've been thinking that I might be better off to make all 4 disks into a raid 5 array and then just make volumes for the system disk and my work disk. My goal is to have a system volume an a scratch/work volume for image and video editing.

I own a PowerMac G3 with 2 hard drive disks. One is a 20gb and the other is a 40gb. I would like to combine the disks with a pseudoRAID type called JBOD. JBOD stands for 'just a bunch of disks.' It's not really RAID. What I'm after is to see these two drives as one 60gb drive. Is that possible? I'm running Mac OS X Tiger.

Can I just remove one of the drives and what are the consequences of the removal. I would like to go from a mirrored raid to a carbon copy of the disk which would be updated weekly and use Time Machine in between.
Do I open up a can of worms - my suspicion is that if I want to do that I'll have to reformat the RAID with the loss of all data.
Any workaround short of making a copy, removing the raid and restoring the data?

I'm about to get a Mac Mini Server for audio, video, and graphic production, in addition to everyday productivity use. If in the same situation, which would you prefer?
1) to stripe (Raid 0) the two internal disks, or
2) use one as the install/OS disk and the other as the data/scratch disk?
(...assuming you have a 1TB external backup drive, and find FW800 to be much slower than internal SATA for a data/scratch disk).

1 "Put the computer to sleep when it is inactive for.."
2 "Put display to sleep after..."
3 "Put Hard Disks to sleep when possible..."
I'm guessing that #1 won't spin down the Hard Disks unless #3 is checked? Is that right? I'm also guessing that if I'm downloading a file or securely deleting the trash my iMac won't go to sleep? The reason I ask is because it seems like if I'm deleting the trash and my display goes to sleep, when I come back to the computer i really don't see any progress. What options do you guys typically use? I keep my iMac on 24/7, but didn't know about the first sleep option.

I purchased a 128gb Patriot Torqx to run as the boot drive for my Mac Pro. I know that the new Intels are coming but I am happy with the Patriots and wanted some instant gratification. The machine is definetly snappier but doesn't quite have the pep as my MBP running a 256gb SSD as the sole HDD.
I have (3) 1 TB 5400 rpm drives in a striped RAID array. It seems sometimes when I start an application that lives on the SSD boot drive, the other drives begin to run as well (I can hear them spinning). Any thoughts on what could be done to speed up my system and also make sure that the SSD runs as independent from the traditional Hdd's as possible?I am running a early 2008 Intel 2.8ghz machine, 8 cores, 6gb RAM.

I have two 1.5TB HDs, RAID 0, as my itunes library. I use Time Machine to back up all my drive, but I also wanted to clone the RAID but only use a single drive as the clone. Will this cause any potential problems since its going from a 2 drive RAID to a single drive.

we recently bought a new iMac with Mavericks and a Lacie 5big thunderbolt series disk. At the Lacie disk we configured as they were 2 hard dsik of 4 Tb each one and added to time machine. Today the user called saying that time machine only made 2 copies one general at 4pm and the other one at the second disk at 7pm and no more copies until 10pm.
I know that time machine makes copies every hour, every day , every month, etc; so we were thinking why it only made 3 copies in that mount of time and why it took the second disk. In the old iMac with Lion this never happened.

I have been troubleshooting this issue. It has something to do with Finder and disks,Running Mac Pro 5,1 with Mavericks 10.9,3 with 10Gb RAM (2x1Gb stock + 2x4Gb), SSD for primary OS drive, 2 TB HDD for Home folder. Have a few other HDD's in the Mac Pro and an external drive for Time Machine
Problems include;Disk Images no longer unmountHard drives (SSD, Home HD, Bootcamp drive) no longer list contents in Finder although Time Machine drive, and 2 other HDD's do list contentsDisk Utility freezes when launched (Freezes at Gathering disk information...)When trying to reboot, Finder becomes unresponsive and can't quit, when force quit, hangs on Grey screen pre-spin progress indicator and required hard shutdown (power button for several seconds)
Tried fixes (in order of trying);Reinstalled fresh copy of MavericksSwitched HD for Home folder (it was giving me SMART warnings)Switched HD's around within the MacZap PRAMInstalled Mavericks on a single drive and things seemed to work fine for several days, so I thought it was my SSDReplaced SSD and reinstalled OS, But now after a day it's doing it again
Other info : I am running CrashPlan which seems to be able to read the disks and back up files (so it seems).Time Machine seems to be backing everything up on schedule..I can run Terminal command "diskutil list" and all the drives show up..I can mount new dmg files, but the contents do not show up but the drive does show up in the Terminal command
When I go to eject them, they stay shown in Finder but are no longer listed in the Terminal command.Activity Monitor shows Disk Utility as hanging, but no other odd indicators.Memory Pressure shows low green in the graph.When I hard shutdown and startup again, everything works for awhile perfectly, but then the problems start showing up.

My dad's iMac was stolen this weekend and am now trying to restore his iPhoto Library from Time Machine backup.
The Mavericks iMac was dutifully backed up over the network to a Mavericks OSX Server Mac Pro Time Machine Server's Drobo for months. I am now attempting to restore the iPhoto library at the Finder level to a Mavericks Macbook Pro.
I have connected to the server's backup disk via Finder and see his "Alan's iMac" listed there without the red minus circle. I then click on the Time Machine icon in the Menu bar and hold down the option key and select "browse other backup disks". I then select "Alan's iMac" and then Time Machine starts up, but it is not showing his files prior to Tuesday, the day I setup the Macbook Pro.
I need to be able to access iPhoto Library from August 30th which came from his now stolen iMac in order to restore to the Macbook Pro.
Info:
MacBook Pro, OS X Mavericks (10.9), 8,1, 16gb ram, 2.3 I5, Intel HD3000

I'm having problems with Time Machine. First, I get the message that I need more space even though there is 1TB available on each and only 500GB on the boot disk being backed up. I've started fresh.
Second, both backup disks are shown on the "Exclude" list and are grayed out, so I can't take them off it. Nor can I add a disk I do want to exclude.
Info:
Mac Pro, OS X Mavericks (10.9.5), (early 2008), 22 GB RAM, 1 TB HD -- 500 GB free

I'm using a 2012 2.5 core i5 Mac Mini running Mac OS X 10.9.3
I recently started using Messages and for some reason, some options are grayed out and cannot be changed - starting from "buddy list" all the way to "when switching users" (see screenshot)
I must also add that I'm not using iCloud nor do I have an iPhone. I use this application on my Mac Mini only

I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.

I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)
My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.

I have a Lacie ext hard drive with 2 x 250gb HD that were one RAIDed into a single 500gb HD. I ran this update Lacie firmware update: http://www.lacie.com/support/drivers...r.htm?id=10053 And now my HD will only show up as two separate HDs of 250gb instead of a single RAID HD of 500gb.

I need to burn a goodly number of files on OS X using a Blu-ray writer. Unfortunately when I write a large number of files with Toast Titanium the app crashes consistently. Are there really any other options for such software aside from Toast for OS X when it comes to Blu-ray?

I have a macpro with 4 x 1tb drives
Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?
Lastly, are the highpoint 3500 series a decent card? and fully compatible?

I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.

I downloaded and installed the OS Maverick's recent 10.9.3 update on my 15" Retina Macbook Pro. However since then I am unable to use certain features, like when I right-click on the Desktop, the menu bar shows only two possible options. I cannot "clean up" the icons on my Desktop anymore. Futhermore, I cannot right-click on some places at all - in Finder for example, nothing happens when I right-click on blank space. Only when I right-click on the icons itself does the menu bar pop up, and that only if the viewing mode is in list, columns, or cover flow (basically not in the "icons" viewing mode).
If I understand correctly instead of showing the possible actions that you can't do in grey, it's simply not showing them at all? Either way it's really ugly, and the usefull clean up application is gone!

MacBook Pro (Retina, 15-inch, Early 2013), OS X Mavericks (10.9.3)

I edit the view options for the Applications window. I make the icons bigger, and I put a photo in the background. The window looks fine until I do a reboot (I don't know about logging out - I only have one user). Then when I open the Applications window I find it has reset to smaller icons on a white background. Doesn't matter what I do when I edit the options. It always looks the same after I restart. I can't say for certain, but I think this problem has been going on since before Mavericks. I thought the cause might be a 3rd party app but I just bought a brand new iMac and the same thing happens.

iMac, OS X Mavericks (10.9.4), MacBook Pro, iPad 2

ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:
How fast is a Sata connection straight from HD>Motherboard... ~75mb/s?
Is the Raid 5 config with all those drives much faster... around ~110mb/s?
Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...
And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc

I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?

I am planning on getting a 2010 MP when they come and have a question about it. I am 90% sure that with my budget, I will not be able to after a RAID card. I am wondering if software RAID would be alright or if it's so bad it's not worth doing. Also, there is small chance that I could buy a RAID card later on, how would I install it? I will be using it for 3D animation with Maya and some zbrush modeling. Also I will be doing some Photoshop and illustrator and maybe some gaming on win 7 boot camp. Feel free to list any other pros and cons about either a software RAID or hardware RAID, I wana make sure I have all the details before making a final decision on it.

I have a Macbook Pro Intel Core Duo (first generation of MacBook Pro released). I run OSX 10.6.5. My disk utility has detected a problem and says I need the install disks that came with the computer. Called apple and they said I could reboot from snow leopard or the upgrade.** Problem is that I don't have any disks with me except those that came with my brand new iMac. Can I use those to reinstall the system? Is there any other way?
**They also said that after 2007, the install disks that come with computers are keyed to that specific computer so I "might" not be able to use the disk to repair.
Additionally, and I don't know if this makes a difference but I have the airport/time capsule which backs up my computer for easy restore.
