Mac Pro :: Replacing 2 Drive Striped RAID With A Single 1TB Drive - How Can I Do It?
Aug 4, 2009
My current setup consists of my boot drive (250GB), a striped RAID (500GB) for storage and a 1TB Time Machine Drive.I have recently bought a new 1TB internal drive and would like to replace the striped raid with this drive, thus freeing up two 250GB drives - 1 which i will keep internally and the other will go into a external enclosure My question is can i just copy the files from the RAID to the new internal or do i have to use software to clone it?

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'm still working out the details on purchasing a new MacPro. My Apple sales rep tells me that I can greatly increase the launch speed of applications and the system OS by purchasing 2 hard drives and using Disk Utility to stripe them together into a "software RAID". They claim it will be faster and more reliable than a single SSD. I know I've asked this question before, but the answers were over my head. I don't know anything about SATA raid cards, or SSD's except for their benefits. But I'm pretty sure I can stripe two drives together and make a software RAID.

Is it possible to mirror a RAID-0 array to a single drive?
For example, I will be setting up 3x1TB on a RAID-0 (striped) array and i want to mirror it to one 1TB drive. Is that possible or do i have to resort to Time Machine ... ugh
and YES i've already STFA! no answers as of the start of this thread

-edit i assuming Time Machine backs up the "volumes" and not the "drives"

My Mac Pro RAID 5 (with Apple RAID controller card and RAID 5 volume with 3 hard disks) showed degraded RAID set message due to failed drive. After I repalced the failed drive, I was unable to add it back to the RAID set. So I tried to removed or deleted this RAID set so that I can rebuild the RAID set from scratch. No matter what I did, I was unable to delete the RAID set using the RAID Utility.

I'll be going with the OWC SSD(s) ExtremePro for the boot drive................ either a 2x60 OSX SW RAID 0 or single 120. I'd rather err on the side of safety but always looking for more umph If going RAID 0 would it be advised to go with a dedicated controller?My data drive will be 2x1T RAID 0.

i have Snow Leopard running in a RAID, and just a separate single drive installed for windows 7. Problem is, when i try to go to bootcamp assistant, it tells me that RAIDS aren't supported in bootcamp. I don't want to install it on my raid, just on the other single drive. Does anyone know a workaround or how to do this?

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.

My system is MacPro 2009 with 10.6.8 server and Apple RAID card. Last week, RAID util just notified me of one drive is not viable, so i decided to replace the drive today. The configuration of my system is... There is an Apple Raid Card for HW Raid system Bay 1 = 640 TB drive with Mac OS X 10.6.8 server installed Bay 2, 3, 4 = 1.5 TB drives set up as RAID 5 below is what I did to replace the degraded Bay 4...
1. I shut down the system
2. replaced the corrupted drive with the new hard drive
3. tried start the machine again.Now my machine refuses to start up with the blinking question mark... I guess that the system fails to recognize the new drive or cannot find the system files...
4. So I put back the degraded drive...
5. The machine still won't start...
6. I tried to use the 10.6 server installation disk to boot up the machine to check if I can fix the system via disk util; but, everytime I do this, I got kernel panic...
7. resetting PR Ram didn't help, cannot boot up via safe mode as well (since the system file is not accessible now, I guess...).
8. booting via 10.6.2 server installation DVD still gives me kernel panic...
Why would my system corrupt by just replacing one degrade drive? The Mac OS X is not even the part of the Raid system... How am I supposed to fix this issue with out the installation disk?

I'm quite new to the OS (Level) Raid concept provided by the Disk Utility within Leopard OS X 10.5.6 and other OS X OS's, but I saw a great video showing 2 USB External HD's hooked up to a macbook running a raid to tie them together (striped or mirrored). This concept is simple! But heres my situation:I have an iMac 22" 2.4 GHz Intel Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM, Running off of a "298.1 GB WDC WD3200AAJS-40VWA0 Media Hard Drive". I also have an External Drive "465.8 GB WD 5000AAV External Media".

Does anyone know if it's possible to have two sets of striped drives using a single hardware RAID controller? I'm looking at the ARC-1210 and it seems like you can have more than one set of striped drives, but I'm not positive. My plan is to have two small SSDs set up for the boot drive and two HDDs for storage, each pair set up with RAID 0. Can this be accomplished using a single controller? Note: I'd just use OS X's software RAID but I need to keep the cores freed up for computation. I'm not concerned with redundancy--just speed.

I have (2) Patriot Torqx 256GB SSD's in a striped RAID array powering my MBP. Where I have enjoyed the incredible performance, it really killed the battery life of this machine.I am in the process of "un-striping" them now and reinstalling OS. Any advice on best configure files to best utilize the new configuration? Should I keep boot files and documents on different drives?

I have a mid-2009 MacBook Pro 17" computer. I bought a 750gb Hitachi drive in an upgrade kit from OWC. I have formatted it and now using Carbon Copy Cloner am making a copy of the internal 500gb drive. I am not very familiar with Mac OS X drive partitions. When Carbon Copy Cloner copies the 500gb partition from my Pro, will it leave the other 250gb or will I need to use Disk Utility or somethng else to format the remaining space? I would like to put the 750gb in the Pro moving the current 500gb into the external housing if possible.

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 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'm a graphics professional taking the plunge into a Mac Pro. After some research, this is my notional drive setup:??GB SSD Boot Drive in the optical bay2 x 1TB 7200rpm SATA in RAID0, partitioned for 1.Data and 2.Scratch (therefore <2TB data)I obviously need to make sure that RAID0 is safely backed up. I've got an online backup service in case my house burns down and I'll be backing up individual projects onto optical media, but I will of course want to Time Machine the Data partition of the RAID.Now, for that Time machine drive I can either create another RAID0 from the same kind of drives (with the risk that entails), or for about the same money get a 2TB 5400rpm (leaving a drive bay free for future use, possibly another backup).

I suddenly have a spare Mac Mini here. It's the first of the Intel ones so it's just a Core Solo, but I figured perhaps I could turn it into a file-server with a large internal drive replacing the DVD drive.Has anybody done this or know of anybody that has? Does a 3.5" drive fit where the superdrive is now, or do I have to go 2.5"?

I have a PowerMac G3 running OS X Server 10.4.7. There is an 80GB ATA boot hard drive and a SATA card and two 250GB SATA drives. One SATA drive is existing and has data on it; I just installed the second one because I want to mirror the 1st drive onto the 2nd one.My questions are: how do I do it? When I try to create a RAID set in the Disk Utility GUI, it says all data will be destroyed. I cancelled that.So I tried diskutil enableRAID mirror disk1, which told me I could only mirror volumes.The volume name is RAID, so I tried diskutil enableRAID mirror /Volumes/RAID which gave me an error "Error enabling disk to RAID Could not unmount disk (-10000)"

I've been hearing good things about the Spinpoint Drives and the 750GB ones are coming down in price.Here is my current setup1 - 500MB Drive - Leopard2 - 320MB Drive - Vista 643 - 500MB Drive - FAT32 (Shared, Irrelevant)I plan on replacing drives 1 and 2 with 750GB Spinpoint drives.My question is, can I boot off of the Leopard dvd and put in Drive 1 and NewDrive1 and just clone it, and do the same for Drive2 and NewDrive2 and clone it? And then go into Leopard and resize the HFS partition, and go into Vista and resize the NTFS partition?

I was wondering if anyone had successfully installed and 2nd hard drive in their iMac?I have a 2 year old 2.8 24'' iMac and the performance just isn't cutting the mustard, it's all hard drive related and I already have a decent 1TB drive in there.I was thinking of perhaps swapping the optical drive with a second hard drive for RAID0, but not too sure if there will be space and was wondering if the optical drive is a standard SATA connector, or if there is some way I could run a SATA+power cables externally?

I recently bought a MBA with the 128GB SSD. When at the store I launched Word on the SSD version as well as the SATA version and there was a noticeable difference so I decided to pay the extra $700 and go with the 1.86GHz with SSD model. I use this machine for development and my builds carry out file intensive operations that delete and generate a few thousand files (when I generate javadocs). My old Dell desktop from 5 years ago completed this operation in 90 seconds but my MBA takes 400 - 700 seconds. I did some reading and all indicators seem to point to the SSD being fast for reads but slow for writes. Is this correct? I'm not sure I can deal with this slowdown for much longer and I'm thinking a having my SSD replaced with the SATA drive. Will the mac store do this? or is there any less expensive option?

I am wanting to replace the hard drive in my macbook but I don't have the os disks that came with the computer (I've recently moved and they're beyond lost). I've read where apple can send me replacements (I assume I'd have to pay for them). Can I get the leopard upgrade and use that, or it just that, an upgrade and I need osx already on the computer. I don't care about backing up anything, as theres nothing on it of any importance, all my music and photos are on an external hard drive.

I just need help trying to take out this darn hard drive. It won't come out. There are two hard drives in my G5 right now, I'm trying to pull both of them out. I tried to do the bottom one first, didn't work. Tried the top one, didn't work. I'm stumped, and I tried my hardest to take them out. I followed these instructions:

The one in the G5 at the minute has not been working for some time, though it accepts the Install discs and Retail DVDs, but there you go.Will it install in the G5 and work? Doesn't seem to say anything about compatibility on the product page so I'm hoping someone here will know If not, any advice on what a good replacement drive would be? Not looking for anything special really just one that will accept discs!

I have a time machine backup on external drive.
I would like to:
1. clean install Lion on the new SSD (120 GB)
2. restore apps from my backup on the SSD
3. keep only data on the existing HDD
My questions:
What is the best way to make it?
Can I just keep the existing system on my non-SSD HDD, and after having Lion on SSD keep just data and delete the system libraries? Or is it better to format the whole disk and restore data from time machine backup (so it is not fragmented..
