One RAID Array Becomes Two???

All:
I have setup a RAID 1 array with two identical segate SATA 150 drives. This was a clean install, and everything went without a hitch. My problem is this: after a week or so, I would boot the PC and The BIOS RAID array would say "Error--Degraded." It took a long time to boot, but was fine and when I got into Windows, my C:\ drive was joined by a D:\drive (the second Seagate.)
I shut down, rebooted, and went into the RAID BIOS. The second drive had magically gained its own array (non-bootable), which I deleted. The PC booted fine with a healthy RAID array, and all was well.
Until it happened again a day later. And again. And again. Basically, the array doesn't stay stable for more than a couple days. I even swapped out the drives with Seagate as they were clicking. The new ones are good, but the problem still occurs.
I have not experienced any data loss, but am mystified as to what is going on here...Any help would be greatly appreciated!

Can't create raid array in 10.4.6

I am trying to create a mirrored raid array with two Fantom USB 2 external harddrives using disk utility.
I am unable to drag the image of any hard drive into the right window and the create button is never activated.
I have restarted, verified the disks and so on. I hve tried to select a different external disk but that won't work either.
Any ideas what's up.

You can try updating the drivers from the makers site, but it could be that Apple won't allow USB drives to RAIDed.
Unless your recording ET or something where a hard drive failure could mean disaster, mirrors are not ideal form of backup.
Consider auto-cloning and auto-backup software like DeJaVu or Retrospect.
What this will do is give you the benefit of time, cloning will "clone" a whole boot drive and make it bootable in case you need it. (You can clone a whole non-boot drive as well.) Auto-backup will copy user type files and folders, but it's not designed to copy a OS from one drive to another.

Remote sync between two RAID arrays

We have two Xserve RAID arrays. One is here in our local office, the other at a remote site which hosts a few of our servers as well. Does anyone have any suggestions for keeping the two synced? I would like to not have to deal with tape backups in the office, but the files being stored here are pretty valuable. I've dealt with this on the Windows side with a tool called Tacit. Essentially that was a Windows box that had proprietary software that would continually update remote Tacit boxes. Anything like that on the Mac side? Possibly free? Would Automator be able to sync me up?
Cheers!

I made a 400.rsync script in /etc/periodic/daily:

Scratch disk with two RAID arrays

I have 2 500GB disks in a RAID0 array for Windows / programs and another 1T RAID1 array for data. Where should I place the scratch disk?

Should I create a dedicated partition on the RAID0 array for the scratch space?
Please do yourself a big favor and do not do any partitions. They will only slow things down, as the OS thinks it's 2 physical HDD's and will tell them (the two logical HDD's), that it needs data at the same time. Remember, it's one physical HDD (even though it's striped, it's managed as one.
Now, here are my thoughts:
1.) RAID 0's will speed things up. However if one of the two drives fails, ALL is lost. I do not recommend using a RAID 0 (any flavor of 0), for the system/program disk. If you do, be sure to have a great backup scheme and use it.
2.) Now, as of CS, PS no longer has a real limitation on how much HDD space it can use for Scratch Disks. Going back, on was limited to 4GB and had the ability to set 4 of these. Back then, having say a 32GB SCSI HDD, and doing some 4GB partitions made sense. Now, it does not.
I'd get a very fast, smaller system HDD. Then, you can use either of those RAID arrays for your media, and the other for your Scratch Disks. Having a dedicated hardware RAID controller will speed things up too.
On my system, used almost exclusively for PS, AI, InDesign, Painter and Video editing, I have 4x 1TB SATA II's for Scratch Disks, 2x 1TB SATA II's for still & video and audio. My system drive is a 500GB SATA II. Were I building now, I'd probably go with RAID 0 for the media and also a RAID 0 for my Video Exports, with non-striped 1TB SATA II's for my Scratch Disks.
Just some thoughts,

Sort two one dimensional arrays

I am having trouble sorting two one dimensional arrays. The first array is int type with ID numbers. I use a bubble sort to sort those. The other array is a string array of video titles. When the first int type array of ID numbers sort, I want the second string type array to follow it. I have tried many things and I can not get it to work properly. Here is what I have for now without the string sort. Can someone help me?
public class Video
     public static void main(String[] args)
     int[] numID = {168, 397, 102, 39, 239};
     String[] videoTitle = {"Godzilla", "Superman", "Hannibal", "Star Wars", "Men In Black"};
     System.out.println("Here are your selections:");
     System.out.println();
System.out.print(numID[0]);
     System.out.println("\t" +videoTitle[0]);
     System.out.print(numID[1]);
     System.out.println("\t" +videoTitle[1]);
     System.out.print(numID[2]);
     System.out.println("\t" +videoTitle[2]);
     System.out.print(numID[3]);
     System.out.println("\t" +videoTitle[3]);
     System.out.print(numID[4]);
     System.out.println("\t" +videoTitle[4]);
     System.out.println();
System.out.println();
//Sorting ID numbers in ascending order
     int a;
     int b;
     int temp;
for (a = 0; a < (numID.length - 1); ++a)
     for(b = 0; b < (numID.length - 1); ++b)
          if(numID[b] > numID[b + 1])
                         temp = numID;
                         numID[b] = numID[b + 1];
                         numID[b + 1] = temp;
          System.out.println("Here are your selections in ascending order:");
          System.out.println();
     System.out.print(numID[0]);
          System.out.println("\t" +videoTitle[0]);
          System.out.print(numID[1]);
          System.out.println("\t" +videoTitle[1]);
          System.out.print(numID[2]);
          System.out.println("\t" +videoTitle[2]);
          System.out.print(numID[3]);
          System.out.println("\t" +videoTitle[3]);
          System.out.print(numID[4]);
          System.out.println("\t" +videoTitle[4]);
          System.out.println();
     System.out.println();

There are ways to do that, of which the simplest would be to switch entries in both arrays at the same time. But since Java is an object-oriented language, the better way to do it would be to make a Video object containing a number and a title, put those objects in an array, and sort the objects.

GX60 Destroyer - installing two SSDs in a RAID array.

I am sorry if this is repeated in another thread, but I am struggling to find any information that could help with me installing Windows 7 Ultimate x64 on two SSDs in a RAID array in my MSI GX60 Destroyer. Windows keeps asking for drivers and cannot detect the SSDs during windows installation.
Has anyone done this before and if so, how did you do it?
Many thanks for reading!
Regards,
Iain

You would need RAID driver from AMD which MSI does not offer it for download.

To make one larger array using other two arrays

Hi,
I have two one dimensional arrays, using these two arrays as index need to create another larger one dimensional array.
like : if two one dimensional arrays namely X and Y, then X and Y should go as index for the final array.
Please help.
Thank you

Failed Boot Camp Install of Vista 32 has broken one of my RAID arrays

Attempted to install Windows through Boot Camp on my Mac Pro, I have a RocketRaid 2320 controller card, RAID was built through Disk Utility. No redundancy, I built 2 separate 1.8TB RAIDs (4 x 500MB drives) in each of 2 separate cabinets. Windows install attempt brought up the HighPoint BIOS, then failed to install Windows and I got the well-known "Select CD-ROM boot type" message. Now, one of the 2 RAID arrays appears to be broken. Disk Utility still sees all 4 drives, but only recognizes 3 of them as a RAID slice with a GUID Partition Table. The other shows up as "disk5s1" with a Master Boot Record as the partition map scheme. While much of what was on this array was redundant with the second, I have a lot of work that was only on this one, so any help in how to fix and/or reconnect the drives of this array would be incredibly appreciated!

1. I remembered RocketRaid 2320 don't provide EFI64bit from Highpoint website so you can't set boot camp.
2. Does your Highpoint raid management utility(Highpoint engineer also called WebGui)
provide any message for your broken raid?I am also a Highpoint user, I give you some suggestion:
A.(1)If your WegGui in Manage--Array show your broken raid status is "Critical"and your bad HDD, please replace bad HDD then select Maintenance items of upper right corner of the page
(2)This will open the Array Information dialog box, select Add disk button to choose the replaced HDD then press "Submit", you can rebuild your RAID array.
B.(1)If your WegGui in Manage--Array show your broken raid status "Disable", you just can use one of Webgui function--"Keep old Data"(But it still have high risks to lose your data, it is the final method to use, I suggest you try the A method best.)
(2) Select "Maintenance" items of upper right corner of the page, from the "Array Information" dialog box, select "Delete" button, and prompted a warning: the array of data will be deleted whether to continue, choose OK..
(3)Back to Manage--Array page, this time the array has been deleted, double-click the "Create Array"
button to display the page to create the disk. From the Initialization Method field select “Keep old Data”, the remaining arrays in strict accordance with the original set of parameters, the required attention parameters include: Number of RAID member disk, Array Type, Block Size, Sector Size.
(4)Click "Create", the initialization process will start automatically, RAID
recovery complete, prompts to create a successful, choose OK.
(5)See your volume in Mac Disk Utility if your data is recoveryed

WinXP-64 bit corrupts existing RAID array

I've got an MSI K8N Neo2 Platinum motherboard running Win XP Pro SP2 on two 36 gig SATA Raptors. Everything was working fine, but I wanted to try the 64 bit version of XP. Grabbed an old 80 gig PATA drive and threw that in the case. Unplugged the SATA drives so as not to risk messing with the existing working OS. Installed the latest 1218 x64 beta and it worked well.
The problem was that when I shut down and reconnected my old RAID array, windows wouldn't boot from it. I lost everything and had to rebuild Windows from scratch. So now I know to never unplug the SATA drives
Rebuilt WinXP on the RAID array and then tried rebooting with the PATA drive with the 64 bit OS. Came up with the "drive needs checking" screen, and proceeds to "fix" the RAID array while ignoring my frantic pounding on the Logitech USB keyboard to stop. Rebooted and yes, the new install was nuked. Okay, since it's gone anyway, reboot to the 64 bit OS and make sure it's got the 64 bit RAID drivers installed.
Reinstall WinXP on the RAID array, reboot to the 64 bit OS on the other drive and the same old scandisk comes and nukes it AGAIN!
So now the PATA drive is sitting on the shelf again, unless someone here can suggest what is causing this problem.
System Specs
Athlon64 3500
gig of PQI 3200 at 2-2-2-5 2.6
2x36 gig Raptors on ports 3-4
Plextor PX-716a DVD+_RW
Visiontek X800 Pro.

The first time you re-installed Win 32 on the raid that was a bit drastic. A repair ought to have done the job.
The problem was probably that you disconnected the array but that's where the boot.ini was and that file needed to be modified to add the path to the Win64 install.
Since you took out the array the Win64 install created a new boot.ini on the PATA drive. Even when you tell BIOS to boot off the array, Windows has a bad habit of looking at the IDE channels & using the boot.ini if it finds one there - but the file it found didn't point to the array of course.
So basically if you already have Win32 on the array I would leave that array connected normally when installing Win64 on the PATA drive and all should be well.
I've installed Win64 on the same array as my Win32 install and they co-exist happily. I reckon that's the most efficient way to do it. The main thing is to make separate partitions for Win32, Win64 and data files when you install Win32 in the first place. The two OSs can share the same data files, incuding stuff like email.

KT4 Ultra: problem config. raid array IDE3

I owe the MSI 6590 KT4 Ultra BSR mainboard and I have difficulties configurring the RAID array in striping mode, on the IDE3 controller.
The manual describes on page 2-18 it's possible to connect up to 2 hard drives, cdrom, 120mb fd and other devices to the IDE3 controller.
Unfortunately only one of my two MAXTOR D740X-6L (6L080J4) 80gig drives is recognized by the array.
One Maxtor hard drive is jumpered as MASTER and the other is set up as SLAVE.
When I hook up the cable to an ordinary IDE port (eg IDE1) the two drives are properly recognized.
Both drives can be formatted using the regular IDE ports, this means without any cluster errors or other errors so the drives are physically OK.
Before I wrote this post I checked the support section again to make sure I am using the latest BIOS which is 1.1. I also downgraded to 1.0, but that didn't solve my problem either.
Since I work in a computer shop now and then I had the opportunity to check two Maxtor Fireball3 30gig drives on a different MS-6590 RAID board (BIOS 1.1.) and exactly the same problem occurs: the 2nd drive won't be recognized in the ARRAY on IDE3.
Please tell me what to do to make the striping option fully work on my two IDENTICAL Maxtor hard drives since MSI support came up with a standard email, which didn't cheer me up at all. Hopefully this time they will investigate this matter since no doubt more people will experience this.

Thanks for the quick response, though it's not satisfactory for me (of course).
Actually before installing the new KT4 Ultra I owed the KT266 Pro RAID motherboard. It's true this board has two controllers for the RAID option. Nevertheless because after reading the manual of this new board I was convinced I could connect two hard drives on the IDE3-channel. This is the reason I decided to go ahead and to upgrade to this new mainboard.
I guess I have to go back to my employer and fall back again to my KT266 (MS6380).

Does "AirPort Disk" work with RAID arrays?

I currently have a RAID 10 array consisting of four USB hard drives all attached to a USB hub. I use it with three different macs (two leopard, one tiger) and have never had any problems. I know that you can attach multiple USB hard drives to an AirPort Extreme Base Station via a hub, but will it recognize a RAID array and make it available as a single volume over the network?

...but will it recognize a RAID array and make it available as a single volume over the network?
Why did you ask that question if the device has never appeared as multiple drives?
I understand that the AEBS is NOT a Mac.
(a) Some RAID devices are hardware RAID devices. These devices use several hard drives but appear to the outside world as a single hard drive.
(b) Some devices allow you to install several hard drives and then these must be pieced together into a software RAID and then appear as a single hard drive. OS X has the ability to do this.
If this device operates like the description in (a) it should have no problem connected to the AEBS.

Which is better, Raid 0 with two hdds or 1 ssd?

Hi,
I have a macbook pro Mid 2010 with two open hard drive bays (thanks to the mce optibay.) I was wondering if it would be better to put two caviar black hard drives in raid 0 on my macbook pro, or have one vertex 2 drive as a boot/applications drive and another data drive.
Thanks
Sam

I understood what the hard-drive-in-optibay meant. Regardless, it's still two platter-based hard drives versus an SSD. An SSD will be faster in your situation. If you had a lot of platter-drives in RAID0 and you had some sort of hardware based RAID controller with battery-backed cache, then maybe, possible, potentially, that (really expensive) platter-based RAID0 could be as fast as a SSD. You don't have that and can't put that in a notebook, so it ain't gonna happen for you.
Now add to the mix, the fact that RAID0 will lose data if any one of the drives in the array fails. You have two drives in RAID0 versus one drive in a non-RAID. The RAID is twice as likely to have a drive failure just because you have more drives. If you made the RAID from two SSD drives, which are more reliable than platter-based drives, then you're got something interesting. But you're still twice as likely to have a SSD-RAID0 array failure compared to a single non-RAID SSD. (And more than twice if it's platter-based drives in the RAID0 versus a single non-RAID SSD.) So it's up to you to determing how much risk you are willing to take...and how much you can afford.
Also note that some Macbook and Macbook Pro models have slower performance on the SATA port for the optical drive. (One assumes Apple tried to save a few dollars and put in a older, slower SATA controller for the optical drive.) I don't know exactly which models but if yours is one of those, then you may get uneven performance on your RAID0. Whether that is noticable or acceptable to you, will depend on a lot of things that you won't know until you try. (e.g.: model of drive, apps you're using.)
And it's good that "backup is easy for you." With RAID0 for the boot volume, you're that much more likely to have a failed boot volume. (IOW, can't boot the Mac at all, which means you'll be using that easily made backup a lot. ) Ideally, workstations that used RAID0 used them for the data, not for the OS. For example, in video editing, the scratch disk needs to be fast, but could be RAID0 because you "threw away" whatever was on the scratch disk after you were done editing, and presumably saved/copied the final edited product to another archival drive. But the OS was on a typical single drive non-RAID (or a RAID1 or RAID5 if necessary,) not on a single RAID0 array for both OS and data.
In your situation, you can't separate the OS and data onto separate RAID arrays, so in general, RAID0 is NOT what you want, regardless of whether you use SSDs or platter-based hard drives. But again, only you can determine how much risk and cost you're willing to gamble with.

RAID arrays and Windows

Not sure where to post this one. You have been very helpful before so I’ll try again.
The machine is the Media Centre in my signature.
Installed two new Maxtor SATA drives, set up as RAID 0, clean install of XP MCE. Boots on the RAID array. Not a single problem. Installed MSI drivers, XFS video card drivers and KCorp PCI network adaptor for wireless link. Download and install all Windows updates. All OK.
On a later start up it spends long time trying to detect RAID array, then RAID error. Automatically reboots and detects a healthy raid array. Tries to open Windows but screen goes almost black but faint Windows loading page with the short activity bar showing no activity. If left it eventually springs to life. Tried starting in safe mode, no problem. Restore to an earlier restore point, no better.
The RAID problem is intermittent. The Windows problem looks as if it stalls for a variable length of time before it gets going.
Don’t know where to go next. Any suggestions?

fafner: I wanted a large disk to hold recorded TV progs, videos, CDs etc and 160GB is the max for this mainboard. I went for 2x160GB Maxtor drives. As I was using two drives I reasoned I might as well use RAID 0 to get a single volume and a faster machine. In particular I read somewhere that RAID 0 halved, or nearly so, the start up time. Who wants to wait a couple of minutes for the TV to fire up?
Fredrik: The XFX video card drivers are in fact nVidia drivers which are the latest.
Doctor Stu: I have subsequently installed XP on both drives individually. On one it worked well, on the other same old problem: either the drive not found in the BIOS after the heading ‘Detect IDE drives’ or the screen fades as Windows starts up. Checked both drives with Maxtor’s Powermax disk checking utility. Provided the drive was connected to the SATA1 socket and the other drive not connected both passed the Full Test. I could not get Powermax to recognise SATA2 even though both were detected correctly in the BIOS. My conclusion is that the problem was a dodgy connection which I hope has been rectified with all the swapping around.
Is there disk testing utility that puts the disc under load similar to Mem86 for memory?
Will I try RAID again? I doubt it even though it did start up in far less time.
My thanks to all.

K8N DIAMOND: New Raid array and old HD... I'm going crazy!!! Please

Hi guys
First, sorry for my poor english...
My problem is:
I bought two Raptor 36 Gb for my new raid array.
I have my old HD Hitachi 250 Gb connected on sata 1.
I connected my two raptor, on sata 3 and 4, I enabled all sata port and raid config for ports 3 and 4.
I restart PC, typed F10 and set a stripe array with two raptor. All run ok...
Restarted and boot with my copy of WinXP with SP2 and NF4 raid drivers.
Installation found my array and my Hitachi;
Hitachi with 4 partitions; C (os), D (driver), E (films), F (music)
I create one partitions on my raid array, and it takes I: letter... So I formatted and start to copy os...
Errors occurs when, restarting pc and resetting the boot to Hard disk (the order of booting is 1 - nvidia array, 2 - hitachi 250 gb), just before loading installation, It shows a black screen with an error: "there is an error in your hard disk bla bla bla.. try to control your connection or connect to windows help....bla bla..."
The Raid array works properly, infact I try to disconnect my Hitachi from sata port 1 and all installation works (I'm writing from Win xp on the raid array).
I tried to connect the hitachi on port 1 of silicon image controller.... same error..!!
I'm desperate... I have all my life on my hitachi...
I think that there's a sort of conflict in drive letter assignement... I cant find a solution ..
PLEASE HELP ME!!!

Glad it worked, I had a feeling it would.
Quote
One question for you.. on G: partition, there's a directory called "Windows", do you suggest me to format this partition??
You can format it if you want to free up space, but unless you moved things around the My documents folder and everything in it is on that partition, along with anything you might of had on the old desktop during that Windows install. You might have something you want there, I usually leave mine for a few month, and figure out if I have everything I need.
Quote
What I have to do, if I need to reinstall WIn XP on first partition of raptor array??
Things should be fine now as Windows marked the Hitachi drive as G. You should be able to reinstall without issue. But if you have a lot of sensitive info on the Hitachi, I would always disconnect the Hitachi if doing a fresh install. Once windows is done installing, hook it back up. But next time you shouldn't have to reconfigure NVRAID after disconnecting and reconnecting.
