Mac Pro :: Force A Lion RAID 5 Rebuild After Replacing A Failed Drive?
Jun 5, 2012
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 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.

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?

Replacing a SECOND failed hard drive on a mid-2007 white macbook (Intel core duo 2.16GHz), this time on my own  Need to purchase a serial ATA drive, but I keep reading that trying to format and/or partition the drive for use with the original Tiger install disk is unsuccessful and that I would have to update to a newer OS before I can do that. I have Leopard as the current OS, and that is in my backup files from Time Machine, but I do not have a disk with Leopard. Wondering the best course of action and/or if someone had success wit ha particular Serial ATA using the Tiger disks?

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...Â
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...Â
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... Â
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... Â
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?

Does this mean the drive itself failed, or that the filesystem or something else software - based failed?

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.

when I upgraded to lion (I think). I also run VMware fusion with windows 7 so maybe a virus? I ran disk utilities, followed suggestions on these communities to no avail. Our IT person and then apple support told me I should replace the hard drive. So I did. I played around a little bit and everything seemed good. Then I did a full restore from time capsule and everything is going downhill again.

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?

After many hours of head-banging, I now realize that Lion cannot be installed on a boot drive that is part of an Apple software mirrored RAID (early Mac Pro hardware, Snow Leopard.)Something about a limitation that a RAID drive cannot be repartitioned to allow for the creation of the Recovery partition.Sad, but so be it.So, I plan to use SuperDouper! to copy my boot drive to a fresh, non-RAID drive, boot from that drive, and then and install Lion there.Once I have done that, will I be able to add the new Lion boot drive to a new Apple Software RAID mirror set? Or is Lion simply not capable of being booted from a software RAID device?

I have just bought a X25-M SSD drive for my MBP (mid-2010). Is it recommend to clone my existing stock drive to get OSX on the SSD or should I rebuild from scratch and perhaps use Time Machine to recover all my apps and settings?
Any advice appreciated.

Since the harddrive of my IMac was full, I added an external harddrive to the system for my photos. I use another external harddrive for time machine back-ups (backing up both the IMac and external harddrive with my iPhoto libraries). Recently the EHD with my photo libraries crashed. I now want to restore it from time machine onto a new external harddrive, but am not quite sure how to do this.

Mail iwill show that I have x (22 for example) mails, but instead of showing the 22 different e-mails, it lists one e-mail, with 22 copies.The only way to get the proper list back, is to rebuild the mail box. When this problem is bad, like today, I've rebuilt my mailbox 5 times in the last hour.

Two of my six mailboxes were duplicated after the update, so I deleted the duplicates in mail preferences. However, the original mailboxes then lost all email content and showed only the headers, so I rebuilt them both and hey presto - instantly lost the entire contents of both mailboxes, including headers. Any ideas for recovering? Have tried hosting server but emails have also gone from there.

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 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)"

why I get this message when trying to burn photos on to high quality discs."The burn to the SuperDrive drive failed. The disc drive didn’t respond properly and can’t recover or retry." I have just managed to burn some others photos perfectly fine.

My brother's MacBook's hard drive just died. He has a backup of all of his data. If I were to buy this, what do I do after installing the hard drive? We have the Leopard disks and everything.

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.Â
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 HDDÂ
My questions:Â
What is the best way to make it?Â
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..

I just replaced the hard drive in my macbook pro 2011 with an agility 4 ssd. I was able to copy all of the information over to the new drive. However ever time I wake the system up from sleep it freezes. I get the pinwheel. I am forced to restart the computer to get it working.
