Intel Mac :: Repair A Damaged Controller For Concatenated RAID?
Mar 15, 2012
My iMac has been crashing a lot lately and finally it's hard drive just up and failed. I have been doing hourly Time Machine backups to a concatenated RAID set (2 USB drives of 1 TB each). However, I think the iMac crashed while backing up and hosed the RAID controller.I've since plugged the two disks of the RAID into my MacBook Pro to see if I can repair them. I can see the individual disks of the RAID in Disk Utility. I can even verify and repair them. But i can't do that with the RAID in the sidebar, and it won't mount on the desktop. When I try to eject it from the DIsk Utility file menu, it says disks are in use.
I'm pretty sure my data on the two disks is intact, but I can't seem to get the RAID to mount as the single concatenated set on a desktop, which makes it inaccessble. Is there a way to repair the JBOD RAID without losing all my data, so I can then restore from the latest backup to my hosed iMac?
Info:iMac, Mac OS X (10.7.2)

Is it possible to add a new 1TB drive to an existing concatenated raid(1TB+1TB)? and is there raid capacity limit, or it's unlimited?

I have a Mac Mini that I plan to use as a simple file server with a 2TB external disk. I would like to be able to add future external disks to grow the original 2TB volume I create to 4TB, 6TB, etc. using RAID.Â
I know it is possible to add disks to a concatenated RAID set without destroying the data on the disks already in the set, but I cannot get Disk Utility to let me create a single-disk concatenated RAID set.Â

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 been searching for a good raid controller with ports for both internal & external drives. Does this exist on the mac side?

I am using the first generation Mac Pro, and I wanted to ask some questions related to SATA HDD and The Raid configuration. I currently have 4 HDDs in the internal bay and 2 external in the enclosure using the USB2 connection. The performance is not that great, and I am sick of adding more HDDs through USB2 which offers really slow performance. I was thinking of building a dedicated NFS File Server using Linux, but before I did that, I wanted to ask if there are solutions out there within Apple Mac Pro without going through this route.
I currently have 6 and probably need to buy 3 more in very short time period. also, all of my HDDs are 750g. Simply put, I am wondering if there are like 16 or 24 port SATA Raid Controller that I can buy for MacPro. Since the MacPro can't house all of them inside, I need to use external enclosures for some of these HDDs, connected through eSATA or whatever means possible without jeopardizing the performance. I am also interested in Raid 5 setup, so, that support in raid card is mandatory.

Can anyone comment on the Highpoint RAID controller Apple is selling?

I'm mostly looking for bulk (non-redundant) storage using an eSATA port multiplied enclosure. Nothing too fancy required. Are there any cheaper basic eSATA multi-link options available? (2006 MP) My biggest concern is good driver support. I see some SI/Sonnet cards that have questionable driver support especially with Snow Leopard.

could anyone please provide more information about the RAID controller? Could I continue to use my Adaptec 5805 when switching from a PC to a Mac Pro?

Can 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.

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.

My dad bought a macbook pro a few days ago and he deleted some things; iphoto and photobooth to name a few. I told him to go to system preferences and he gets an error message saying something about 'system preferences may be damaged' And it does not open. Is there a way to fix this? He has the snow leopard installation disks etc.

I dropped my MacBook Pro only about 12 inches and the corner of the shell where the Magsafe connector is located was bent slightly inward. When connected to the AC power there is enough power going through to run the laptop. However, the battery is not charging and now has no green lights when I push the button on the battery. I checked and the battery has been through 129 cycles so should still be good. I'm assuming that means something was damaged with the Magsafe connection when the corner was dented. Does anyone have any advice? How much it would cost to repair the Magsafe connector? My MacBook Pro was purchased in 2007 and I have no other issues with it. Would it be worth repairing or should I get a new one?

I set up a RAID using 4 Segate 320GB SATA drives in it's own box. It is connected to my G5 (OS 10.4.1) via a Highpoint RocketRaid 2210 card. After 2 months, I have gotten the b-node tree error twice. The drive fails to mount and drive utilities (including Drive Genius, DiskWarriror) can't fix it. I was able to use Drive Rescue 2 to get the info off of it, but I am concerned as to why this keeps happening. I can reinitialize the drive and get it working again, but this is not a solution.

I currently have a 1TB and a 500GB disk as a concatenated disk on my computer.My iTunes library is stored on there and it sometimes takes a second or so to load up my library.As my library is fast approaching 1TB, what would be my best course of action?The Samsung Spinpoint F3 1TB is on ebuyer for ?47 at the moment, which is a pretty nice price. Should I give up on Apple's software solution and look for a raid card that will give me RAID-0 for two 1TB disks?What would give the best performance? I can't afford a Drobo and don't want anything plugged in externally if possible.

Intel based iMac ~ 2007 boots to a blank white screen. It will not boot. The problem just started when I attempted to reboot and reset holding SHIFT-CMD-P-R. I'm not all that knowledgeable of tech things on the iMac. But if possible to get the iMac to boot up again what should I do?Â

1st problem was IMac running slow. Shut down and unplugged several times with no correction. Eventually, shut down, unplug and reboot resulted in wallpaper background eventually coming on screen but no icons. Nothing after that.

Does anyone know how to remove 360 Controller Driver Daemon from the Startup Items on an iMac? I downloaded this so I could use an Xbox 360 wireless controller for Onlive but since downloading this I get a conflicting driver error when I load up Onlive. I thought I'd deleted this from my mac but I can still see this sitting in System Information/ Software/ Startup Items but I can't remove from here. It does not display in my System Preferences to allow me to remove from the Startup Items?

I use my Mid 2010 iMac for virtualizing routers. I noticed that with the 4gb of RAM that was already installed in the iMac was not enough. So, I did some research and found out that, my iMac can hold up to 16gb of RAM. I did some more research and found out how to replace the memory in my iMac. Then, I went to Micro Center and bought 16gb of RAM and brought it back to my apartment. Now, I powered off my iMac and unplugged the power cord, flipped the iMac upside down and unscrewed the three screws that were holding the memory cover on. After removing the memory cover, and pulling back the memory tabs/flaps, I shined a light down in the memory slots and found one memory slot that looked damaged. I was not completely sure, so I went ahead and removed the old memory by pulling hard on the memory tabs/flaps, and the memory was unseated.
I remove the memory and replace it with four, 4gb sticks of memory. Once I powered on the iMac, a memory beep sounded off. So, I unplugged the power cord from the iMac and removed two of the four memory sticks out of the iMac. The two sticks of memory I removed was out of BANK 0/DIMM0 and BANK 1/DIMM0. BANK 0/DIMM0, is the one that is damaged and my hardware warranty has expired. I bought this iMac damage, and now it won’t support 16gb of memory. What should I do? By the way, the other 8gb of memory in the other two BANKs are working.

It looks like the surface of a few keys has been eaten away by acid, I can only imagine it has happened because my fingernails touch the keys through normal typing, but this is completely unavoidable unless I type like a one-fingered man. It mainly seems to happen on the A and S keys, this has happened on my white MacBook, Wireless Aluminium keyboard and Wired Aluminium keyboard, but as they are so expensive to replace I am not willing to buy a whole new keyboard for this. Also, one of my cmd keys has an odd stain on it, possibly from a crumb or droplet of orange juice which I'm sure I would have wiped off immediately, I wouldn't have expected plastic to stain so easily. Has anyone else found this with their Aluminium keyboard?Â
I suppose there's nothing much I can do to prevent it (I refuse to use a silicone cover), so my option appears to be just to replace those keys damaged through wear and tear however I can. Are the keys interchangeable between these three keyboards? (Wireless / Wired Aluminium, white 2008 MacBook Core2Duo) The main keys look the same apart from the bottom row on the Wired Aluminium keyboard which are a bit wider.

Disk Warrior reported a damaged resource header that cannot be repaired. The resource header is in an "older" file format (rsrc). I have been having fairly frequent freezes of the system and Disk Utility reporting a corrupted HD which Disk Unility is always able to repair and report the HD to be O.K. Could the damaged header be the cause of the freezes? If so, can anything be done about it if Warrior says it cannot be repaired?

I got SMART warning about my hard disk, I got it replaced by a shop, but said I would do OS restore myself. (cant afford cost )Thought it would be simple - but it is anything but.  It appears my install DVD is damaged, so was not able to boot with Grey OS install disk - holding the C key.I managed to get iMac to boot up using the old disk - using firewire dock. However I was not able to restore old disk and OS to new disk, Due to IO read error.(this is why I had the SMART warning). So I am unable to get the OS on the new HD using the old disk or the DVD as these are both damaged.  The computer is running, so I thought I would try buying and downloading LION - then using the migration tool . The download is still running after 2 days.I went to apple store, and was told that they cannot replace DVD , so I should bring in the iMac = and pay for the restore. Dont wish to do this. As I have the computer and OS running, is there anything I can do to get a time machine restore from another backup disk (USB).

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.
