I want to reformat and install SL fresh and am getting an error when i use Disk Utility (booting from SL DVD) to delete the RAID0 config. The error is "invalid request".
I have 4x640 in Software RAID0 that i boot from.
I'm planning to replace my boot hard drive with a pair of RAID0ed SSDs. In order to familiarize myself with certain techniques I have build a software RAID0 from two 160 GB Maxtor SATA I hard disks. That went pretty much without problems. The two HDs are now sitting in position 1 and 2 in my Mac Pro.
The problem arises when I try to clone my boot drive onto the new RAID 0 drive. I was using disk utility and got an error message. Then I thought my fault was using disk utility from the HD which I wanted to clone and booted from the Leopard install disk. I then used disdk utility from that source to clone the HD boot drive to the RAID. Again I got the error.
What is going wrong? Do I have to approach this completely different?
I've got a 2 drive 640GB Black Caviar RAID that I want to set up as just an OS and apps boot drive.
I realize larger block sizes have more through put but waste disk space, and smaller sizes save space but are less efficient.
My user folder (mail, media, itunes, video, docs) will be on a separate drive.
(1) So how do apps and OS files load at boot time and runtime?
(2) If apps like CS4 are large apps does it not make sense to set 256K as the block size?
(3) Or does OSX use many small files thus needing a smaller block size?
I have a Mac Pro 2008. I just got my second Crucial 256 gig SSD. Wanna make it a Raid 0 with my first one. Here are my thoughts.
Process 1:
1. Use disk utility to restore image of original Crucial 256 SSD to external USB drive
2. Boot up with SL DVD
3. Build Raid 0 using two drives. (do I need to 0 out?)
4. Restore image to Raid 0
5. Boot
Process 2:
1. Boot off DVD
2. Create Raid0
3. Use SL to restore backup from time Machine to Raid 0
4. Boot
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.
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).
View 6 Replies View RelatedI'm having a hard time deciding what to do with my two open HDD bays in my Mac Pro.I know I want to add more storage, but I'm not sure if I should use Raid0 or not.I store most of my media on a server but wanted to store the following in my MacPro and would need more hdd space.Bootcamp - obviously can't store in serverScratch drive - would write handbrake encodes to this then transfer to serverIn all I'll need around 1.5tbI already have a 1.5tb drive and would only consider buying another to put them into raid0. Should I bother with raid0 for the increased speed or just use the 7200RPM 1.5tb drive I already have?
View 11 Replies View RelatedI have successfully striped two SSDs in Vista Business-64 on my MacPro1,1. I have used Vista's data carrier administration program for this. As expected the array isn't recognized in OS X. So I cannot just dump a Winclone image on the array. That would have been much to nice!
My next strategy was a total backup with Vista's own backup program on another HDD. That went without a hitch. I then hoped that booting the Vista install DVD with the backup drive present and the RAID0 array would allow me to restore the backup on the RAID array. Unfortunately Vista will not recognize the array running of the install DVD. Loading AHCI or IMSM drivers will not change this situation.
It appears that you have to make the dynamic data carrier active if you want to install Vista on it. Unfortunately the data carrier admin program will not let me do this. I would do it in DISKPART if I knew it was possible and how to do it.
So the question is does anybody know how to install Vista Business to a dynamic data carrier? If I cannot figure out this soft RAID0 I will ave to buy a RAID controller which I thought I might avoid at this point.
is there i can delete the boot camp portion of my hard drive ( tried putting windows on the other half, but its more of a PITA uploading all the drivers) is there a way i can remove the boot camp portion of the hardrive without loosing everything on my mac hard drive?

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?
View 2 Replies View RelatedI am thinking about adding a pair of Sandforce SSD drives in RAID0 on my Mac OSX device. Since OSX does not support trim I am dependent entirely on over-provisioning and idle garbage collection to keep SSD drives in good shape long term.
My question is if you use two drives that support BGC in a software RAID0 configuration does the BGC still work as effectively as with a single drive long term?
If I have iTunes on an SSD drive (the boot drive in my Mac Mini), can it read the music library on a second rotational hard drive? I'd like not to have the large music library on a 120GB SSD drive.
View 3 Replies View RelatedThis is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

I decided that I couldn't wait for Gainestown and ordered a 2.8x8 MP today. I'm going to get another 8GB of RAM (I assume 10GB in matched pairs will still perform at full speed). My real dilemma is a Boot/Storage solution-I'm moving from a Dual 867 G4, so all my current drives, both internal and external are IDE, which basically means I'm starting over as far as internal drives goes. The G4 power supply gave out so I'm getting this external enclosure to put my old drives into for file recovery. As far as new drives go, I can't figure out what to do. I'll spare you my million iterations of drive configs I've sketched over the past two days.
View 14 Replies View RelatedI run SSD/HDD, my HDD in the optibay is broken, I stuck it in a external and it makes finder freeze, it got bumped around too much so I want to put a new one back in the 'correct place' for a spinner, and stick the SSD in the optibay.(I figure the extra 2% of shock protection offered by the orange rubber circle things is worth the trouble of moving everything).
I am also going to buy a WD 3 platter 1TB laptop drive, and I read that they fit fine in the regular spot in MBP's (I'm going to open and measure in a min.)Anyways, there's no BIOS, only EFI, so how to I pick what drive to boot from? with 10.6 is it as simple as holding option down on boot, and picking my 'OSX' HDD, and then it will auto boot from that until I specify otherwise? (I ask because before 10.6 people on here were always talking about how to switch boot drives.)
I used Boot Camp to setup a partition for installing Windows. I no longer need the partition nor Windows. How can I delete that partition and make it useful for my laptop?
I'd like to have it as just one big hard drive rather than it showing up as 2 separate hard drives. I believe it's called extend the hard drive if I'm correct.
I am having problems. I want to delete a partition and create a new one, but I need to be able to click option in able to do this. For whatever reason, disk utility will not let me edit my external in any way without deleting the whole thing which I do not want to do.

View 5 Replies View RelatedMy friend gave me his old Apple cube G4 + 15" Cinema display in like 1000 pieces. Its completely teared apart. I tried a lot, but it doesn't work. The original IDE cable wasn't included, so I bought one for 2 cents. It should work or not? Maybe the powersupply. I'm not sure. I don't believe actually that the hardware itself, like the motherboard is broken. When everything is into place and I connect the cube to the powersupply it boots immediately. I don't have to do anything. Harddrive spins and the superdrive makes some noise as well. This repeats itself every 5 seconds. The screen is connected and gets power through DVI, but no display. Both the cube and display have touch enabled buttons to switch it on, but they do not respond (I guess).. Motherboard gives 2 light. DS1 is green, DS2 is red.
View 3 Replies View RelatedI have two WD 640gigs and the stock WD 500, and I am having trouble deciding on the the optimum configuration. I am open to suggestions. I use my computer for general use as well as for my video editing and graphic design hobbies if that info helps.
I am curious as to the benefits of of the following:
Drive 1 (640)
partition 1: 150gig for OS
partition 2: Bootcamp
remainder: Offline storage
Drive 2 (640)
partition 1: Applications
remainder: music/photos
(scratch disk here?)
Drive 3: (500)
Time machine
Would there be a noticeable benefit to having the applications being separate from the OS boot drive? What if anything else should be split across multiple HDs to increase speed? I've heard of moving the swap file from elsewhere on the forum but I am not sure as to what exactly that is nor the benefits of doing it.
My final question(s) is how exactly I could go by moving my application folder to another drive separate from the OS drive? Just drag and drop? What is this deal with making an alias?
My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it?

View 8 Replies View RelatedHere's another speculative question for if/when I get a Mac Pro:I don't forsee myself needing the multiple terrabytes of storage most of you guys seem to have , since I'm still doing OK with just the stock 250GB that came with my G5 Quad + an external 120GB. I'll probably get a 750GB drive for boot, apps, and most files (leaning toward SpinPoint F1 750; the new 640GB WD also seems enticing).So, here's my Q: which would be a better setup for apps like Photoshop as well as the OS (I've read you can relocate the swap file?), performance-wise (both in terms of app speed, and keeping the OS from hanging on a busy disk) - using the slow stock 320GB as a more dedicated scratch disk (possibly just a partition on it, with other partitions for Windows), or using the free space on the faster, but non-dedicated, boot and storage disk?

View 7 Replies View RelatedI'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.
