I just got the apple mac pro raid card today, but after I connect it and all 4 SAS drives, the MAC OSX Installtion program can not detect the SAS at all, I open the RAID Utility but no dirve there, the battery is in charging status.
View 2 RepliesSo I have followed a bunch of the 'MacPro with mac raid card users wanting to do bootcamp' threads. I have attempted all the hacking required but have not been successful. I heard that bootcamp 3.1 will fix this problem possibly... so in the mean time I would like to remove my SAS drives and raid card and just use the sata drives that I have to do Mac OS and Windows.
I have removed the card but when I plug the drives in and boot up the machine, the drives are not recognized. Is there some plug that I need to reconnect somewheres?
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 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 have never setup RAID before and this question may be totally stupid for that matter.
Can I setup RAID 1 (or call it mirroring) without the RAID card? I have two 1TB internal drives in my Mac Pro and I want to mirror them. I don't want to spend another 700 bucks just to setup a mirror.
Disk Utility shows some RAID options, but I am not sure how to use them, or if they will work at all without the RAID card.
This is an intermittent problem. I have a dual processor PowerMacG5 2GHz. The computer won't boot up. Used disc utility to find out that no hard drive was detected. Thought hard drive was bad. Installed new hard drive. Installed Tiger. Rebooted. Computer won't boot, disc utility shows no hard drive. Unplugged computer. Removed hard drive. Started disc utility from disk. Turned off machine. Unplugged. Installed hard drive. Started up machine. Machine runs fine. Now turned machine off and tried to restart again, now no hard drive detected again. Redid unplugging and reinstallation of hard drives. Now both hard drives works fine. This problem can be repeated. I prefer not to ever turn off my machine again. Startup procedure with unplugging, reinstallation of hard drives is just a pain.

I installed 2 ne w Optical drives in a 2008 3,1 MacPro Quadcore.After installation and booting up, the system profiler failed to show ANY optical drives and I was unabel to open/eject the drives naturally. I then unplugged the bottom one and rebooted and the top drive (still plugged in ) worked. I then shut down and unplugged the top drive and plugged in the bottom drive - rebooted and now the BOTTOM drive is recognized. When BOTH drives are plugged in , the system fails to show either of them.So when individually plugged in it's fine but when bith are plugged in neither of the drives are detected or operate.
View 5 Replies View RelatedThe time has come to move to a RAID setup in my Mac Pro. Ideally I'd like to run 4 1.5TB SATA drives in a RAID 5 or 10. It seems there are a LOT of threads on this topic all filled with different information, so I have a few questions...
Which RAID cards are bootable?
Do any work like the Apple card and interface with the drives through the logic board?
If not, how do you connect the internal drives to the RAID card in their stock bay locations?
I just got a brand new MAC PRO desktop. It came with a 600GB HDD. I purchased a second identical internal 600GB HDD. I wanted to do setup a RAID 1 using these 2 drives. Currently the main drive has the OS and all my other apps installed. I installed the 2nd drive and was fooling with disk utility. I'm not sure how to set this up however. I tried numerous guides online but I just cant figure it out.
MAC PRO (takes up to 4 internal drives) - currently installed 2 identical drives
Leopard
Using Disk utility
The RAID tab says "online" and the status is green (indicating the RAID is working). However on my desktop i see the 2nd hardddrive mounted with no contents in it. I just want to able to use the 2nd drive as a mirror so this way if one fails I'm still up and running.

View 4 Replies View RelatedI currently have a 2TB WD mirror edition that is setup in RAID 1 so it will mirror all my data. Now I also have a bunch of other drives laying around which I also feel the need to back up and currently I am doing this by doing a whole bunch of dragging and dropping and copying and pasting etc etc etc and this is making me very tired. I know that a setup is possible in disk utility but I am not at all sure about how to configure it so I wont lose any of my data.
Some details about my setup:
Mac OS X 10.5.6
PowerPc G5
Harddrives: two 1TB WD MyBooks, and two 500gig WD Mybooks --> these pairs need to mirror each other and make my life less of a hassle.
I'm about to configure my 2006 MP with one of Apple's RAID cards using RAID5. I currently have 4x 750GB drives that I can use, but I can see needing more space in the not too distant future. When I do need more space, can I simply drop in a 2TB drive, let the RAID system reconfigure itself, and repeat this until I have all 4 drives in place? Is there a better or different way to do this? I know that if one of the drives is larger than the others, then only a drive space equivalent to the smaller drives will be used in RAID5. After addition of the fourth drive (per the above scheme), will the array then use the full 2TB of each drive?
View 7 Replies View RelatedSo I have a Mac Pro with Bay 1 acting as my regular start up drive. I also have three other Western Digital 500GB hard drives that I have been using as a RAID backup system. However, when I place all three of the RAID hard drives into Bays 2, 3, and 4, the computer will not boot. It never reaches the Apple logo, and continually tries to restart. So I figured one of the hard drives was corrupt.
However, I have tested all three hard drives in Bay 2 and the computer will boot just fine. I have also tested each bay individually (i.e. the same RAID hard drive in each of the Bays seperately) and the computer still boots fine. I can even power up with any two hard drives in Bays 2 and 3. The only time I can't power up is when all three of the hard drives are occupying all three of the extra bays.
Also, none of the RAID hard drives show up in Disk Utility or on the desktop. Shouldn't I be able to view them as normal internal or external hard drives being plugged into my Mac? They do show up in RAID Utility. Is this normal with RAID hard drives, or should they always show up in Disk Utility?
I created a new RAID backup with two of the drives together (Bays 2 and 3) and it recognizes it in System profiler. However, I want to be able to use all three drives for the RAID.

I have a SD 16gb card that contains .mts files from my Canon S100 Hd camcorder. My card reader which is years old does see it in my PC but not on my Dual G5. I plugged it into the front usb slot and back one.. My mac does not see it. I tried the keyboard but it says it is too low power to use from there. How do I get the G5 to see it?
View 4 Replies View RelatedI have a 8-core MP 2.8Ghz with 10gb ram and Ati 2600HD. I'll someday replace the ATI with a quadro (all my application is 3d/CAD/Design) I'm installing 4 of the WD640 drives, they arrive on Friday.
I would love to order the CalDigit RAID card but after searching I finally figured out it's not available until next month.
That said, I need my system to start working ASAP and I don't want to wait if I don't have to.
I'm a designer, I need fast scratch so some striping needs to be involved. I also need data protection. At this capacity Time Machine isn't going to be of any use and I'd prefer redundancy anyway.
The 4 WD640s are replacing: 1 750gb 7200.11, 2 WD SE16 500GBs, and 1 320GB (Apple Stock Drive).
I would like to sell some of those drives to defray the cost of this endeavor but I'm open to keeping 1 or possibly 2 as external drives or stuffing one into the optical bay with a converter.
I want speed and reliability, of course! But really the largest motivator here is the combined drive aspect. Having so many volumes is driving me nuts.
My intention had been RAID 5 or 6 but I now know that Apple Software RAID can't do this. So now it seems with software RAID 0+1 would be the only option.
Realistically, does the cpu performance degradation outweight the speed gained from striping the drives? It's so difficult to determine bottlenecks.
Any thoughts on my best bet without/before the RAID card arrives. Can I migrate the array after installing the card without data loss?
If I just JBOD the drives can the concatenated set be broken up ever? I was thinking I could JBOD until the card came.
Anyone know if it's possible to attach two USB hard drives to a Time Capsule via a USB hub, and configure them in a RAID1 configuration and use them as my Time Machine backup disk? I would then use the TCs internal drive as network storage.

View 3 Replies View RelatedCan I install a Raid Controller and connect say two drives to it, specially for windows? Will it be bootable? Or perhaps even connect the iPass of the four internal bays to an Adaptec 5405 and get a separate cable for my Mac Drive. Will both be bootable? What if I just want to boot Windows for now? I sometimes need to convert my early 2008 Mac Pro into a rather beefy Windows workstation and the lack of HW Raid is rather irritating.
View 1 Replies View RelatedI have read that it is "a shortcut to disaster" if I do a RAID0 (or any other RAID for that matter), if the Hard Drives are dissimilar. I have the original HD 149GB (now 5 years old), and have bought a new 1T HD, and was planning on setting them up as a striped RAID0. Is this a bad idea? Should I purchase a second 1T HD and do a RAID0 or RAID1 setup instead?
View 10 Replies View RelatedI have a Mac Pro with all hard drive slots filled. The first two disks (includes startup disk) are independent, and 3 and 4 are set up in a RAID 1 mirror. I have to take my computer into the Apple store for a repair and I'd like to just take out all the disks except for my startup disk... however I'm not sure how to go about doing so for the RAID. If I take the drives out, and boot up the computer with them no longer inside, will the computer "freak out" and/or will the computer no longer recognize the RAID if I put them back in again later?
If the latter is the case, will the data be lost or would I just have to set up the RAID again... and if I do that, will that also cause the data on the drives to be lost, or is it possible for it to mirror them again without needing to make changes to the data?
What should I be doing to my drives before building arrays with them?
Hitachi do a Drive Fitness Test and Seagate something similar but I have not been able to get either to work on a BootCamp Windows partition.

I have two choices.
1. Apple's Mac Pro RAID Controller, Four Drives, RAID 0+1. One big disk, highest cost.
2. Or, some other RAID Controller (?), Three matching drives, RAID 5. Then, 1 big drive for OS/Applications/Time Machine.
I'd probably move my Home folder to the RAID Array and have just my data striping amongst those drives. Has anyone had a dilemma like this before? I like the idea of hardware separation of my Home folder from the OS.
I have been reading about people taking a SSD drive for Boot and OS and using a second HD for their data using MCE's Optibay hard drive enclosure.
I would love to go this way but I can't justify spending all the cash on a SSD yet. Could I put in 2 500GB 7200 rpm drives and RAID 0 them? I know this wont be as fast as SSD but it should be faster than a single hard drive and hold a lot more storage for less $$$.
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.
