RAID 1 for a Disk with 2 partitions?

So I have 2 x 2TB external hard drives. My goal is to have drive "A" contain 2 partitions, partition 1 being OS X Extended Journaled and partition 2 being Windows NT File System. I would then use the Mac partition for time machine backups for 2 of my macs, and use the windows partition to basically store files, data, and the like.
Next, I would use drive "B" as a redundant disk in a RAID 1 setup so that if drive "A" ever failed, all of my time machine backups and miscellaneous data would be left 100% intact.
So, I suppose my question is...is this type of set up possible? Am I able to create a RAID 1 setup covering 2 partitions (non-alike) partitions? If so, what is the best way to do this?
Thank you

USB2 doesn't have the bandwidth and RAID only puts an added burden, and USB does use cpu for processing. USB3 would be better.
There are some cases that might make more sense and built for what you want, but a mirror raid should be after you already have a primary backup, not as your backup method. THAT is where the redundancy comes in, and always have one backup set that is not online at any given time.
OWC carries a number of interesting external backup devices.

Maybe a network attached drive or server would even do better. Low end NAS drive or full blown $500 server, with support for NTFS and Mac, TimeMachine and Windows Home Server, as well as full media library support and streaming for itunes and such.

Setting up RAID for a drive with user folders on it!

We have one hard drive for user data, partitioned into 2 volumes, IDHome and IDData. IDHome contains the home directory for all the users. IDData is shared network data. I want to set up a Raid 1 array for this entire drive, however it seems that you cant do this on the fly without erasing both drives. Ive got a second identical drive, but when I try to create the array in Disk Utility, it wants to erase both drives. That would be a catastrophy of monumental proportions!
Everything from the original drive is backed up, so Im not affraid of losing anything. But I dont even want to go there.
Hers my main qustion. If no users are connected to the server and I backup the original HD, set up the Raid array (thus erasing both drives), then copy everything back onto the array, are users going to be able to log in as if nothing happened? Is OS X going to care that /Volumes/IDHome is no longer on /dev/disk1 and instead on the Raid array now (/dev/disk2 I guess)? Is OS X looking for specific hard drives or just at /Volumes/IDHome?
Ive read a couple of articles on the internet about using the command line diskutils to first enable one drive as a raid array, making the computer think the array exists, then adding a second drive to the array and "rebuilding" the array... but I go back to my original question, is osx going to care that /volumes/idhome isnt technically on /dev/disk1.
I tried to test diskutil enableRaid mirror /dev/disk2 (/dev/disk2 is a backup drive we have installed on the server), but I got an error message saying the syntax needed to be in diskutil enableRaid mirror /Volumes/VolumeName format...it wanted /Volumes in stead of /dev is guess.

You can't partition an Apple software raid drive.

Looking for starup disk - with a twist!

Here's a new version of the "startup question mark in a folder" issue: I only have the problem when restarting (selecting restart from the menu or after installing new software). On restart, the question mark in the small folder appears, telling me OSX can't find the startup disk.
This does not happen on a cold start. If I force a power down afer a restart, it boots up fine, with no search for the startup disk. My start up disk is set to the internal disk, OS X, via the startup preferences.
Additional info, possibly relevant: this began after upgrading form 10.2.8 to 10.3.5 via a disk from my local mac dealer. (They advised against Tiger on this computer, given its age & general G3-ness) It was a cranky install, mostly because the CD wouldn't autoeject on restart (I reinstalled the drivers for the superdrive - I think that may have been the problem). Also, I'm fairly sure (I'm not in front of the computer now) that I moved Classic off the internal drive to an external firewire drive, as I never use OS9 and would just as soon have the room on the internal drive.
Thoughts? Anyone? Beuller? Thanks in advance.

Hello from Barcelona, Kai-bcn.
Problems arising right after installing a system update are usually the result of some filesystem corruption that should have been fixed first, or not having installed the update properly (e.g. applications running while installing it), or having ignored Apple’s “Important: Please read before installing” warnings, etc.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, reinstall the update using the combo installer:
About the Mac OS X 10.4.9 Combo Update
Mac OS X 10.4.9 Combo Update for PowerPC
Mac OS X 10.4.9 Combo Update for Intel
After installing the Combo Update, the computer may restart twice and the first restart may take several minutes. This is normal.
Take a look at the following articles for guidelines on how to properly install system updates:
Troubleshooting installation and software updates
Installing software updates
That said, the problem in this case could be some kind of cache corruption. Read the following article for general troubleshooting and cache-cleaning procedures:
Resolving Disk, Permission, and Cache Corruption
In addition to the utilities mentioned there for cache cleaning, you may also consider OnyX or Cache Out X, which are free.

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,
Hunt

Help with software RAID on system disk

I've been trying to get my OS system disk mirrored using diskutil's software RAID (my server has 2 internal 80GB drives). I did what homework I could and here's where I'm stuck. I'm running 10.4.3.
n506:~ root# uname -a
Darwin n506.local 8.3.0 Darwin Kernel Version 8.3.0: Mon Oct 3 20:04:04 PDT 2005; root:xnu-792.6.22.obj~2/RELEASE_PPC Power Macintosh powerpc
n506:~ root#
According to my research, I needed to boot from an OS disk other than the one I want to mirror, so I installed a second instance of OS X on my second drive, booted on that and ran diskutil enableRAID against the system drive I want to protect. This appeared to work. A new disk device was added (the RAID device) with its only component being the disk I ran enable RAID on. Then I booted from that disk. Here's the problem.
When I run diskutil addToRAID to add the second disk to the raid group, the command does partition the disk the same way the primary is partitioned (according to diskutil list), but the command always fails with this error:
n506:~ root# diskutil addToRAID member disk0 disk2
2006-05-27 23:49:50.012 DiskManagementTool[362] AppleRAIDUpdateSet failed to modify the set (null)
There was an error adding the disk to the RAID (-9960)
n506:~ root#
The system log shows this:
n506:~ root# tail -1 /var/log/system.log
May 27 23:49:50 n506 kernel[0]: AppleRAIDMember::readRAIDHeader: failed, no header signature present on disk0s4.
n506:~ root#
[NOTE: I should add here that, for reasons unknown to me, my system created /dev/disk0 from the drive in the second bay, and /dev/disk1 from the drive in the first bay (the primary disk I'm trying to mirror). I have no idea why OS X set up the devices like that, but I haven't really worried about it]
I've done what research I could and have found no information on this problem. I've tried zero-ing the second disk and rerunning the command (along with rebooting), but I always seem to get this error.
Any help would be greatly appreciated. I've been at it for days now and I'm really frustrated.

I am trying to install bootcamp with windows xp professional on my macbook core duo. This is my first mac and i just purchased it. The disk will partition but when i try to start the installer a white screen appears then a folder with a ? in it appears

I just recently purchased this macbook. The optical drive was faulty, i opened it up and rubbed alcohol on the lens and that didnt work. I connected an old ide dvd rw drive in a 3.5 enclosure and it seems to work like a charm. I installed snow leopard with it so i know that it is in complete working order. I also upgraded the ram so that should not be an issue either. This is a first generation macbook 1.1 with the core duo processor. I just want to install my xp professional operating system onto this unit. I have the original xp professional disk with service pack 2, not a burned iso. When i try to launch the windows installer the dvd drive fires up and it seems like its attempting to launch windows then the screen goes from bright white to a folder with a question mark on it. From there nothing happens. Is there something i can do or that i am missing here?

Your problem is not Boot Camp, in fact, is your optical drive. Win XP requires indeed sp2, but also the internal drive, does not work from external optical drive.
For other possible tricks, please use the appropriate Boot Camp forum, not here. Mac OS X may be installed from both external and internal optical drive and/or internal/external partition of a disk, any disk. Windows is not so generous.

Odd problem with partitioning the disk-- it says it needs to be a single Mac OS Extended (Journaled) volume, but it already is? (Screenshots in post)

I have a 1 TB Macbook Pro running Mavericks.
My disk is a single-volume...
Here is the information on my disk:
And I'm trying to use boot camp assist to partition my disk, like this:
But when I do, I get this error message:
"The disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
It already is a single Mac OS Extended journaled volume. Right? Here is an image from Disk Utility:
Any ideas?

Hey there!
It sounds like you are unable to install BootCamp due to an error that your some files cannot be moved, and to format your disk as a single volume, but you have confirmed that it already is. I would verify and repair your disk permissions with the following article next, if you have already restarted your computer and tried again:
Disk Utility 12.x: Repair disk permissions
http://support.apple.com/kb/ph5821
Choose Apple menu > Software Update to make sure you have the latest version of Mac OS X.Software updates sometimes change a file’s permissions to improve security, so updating your software can solve some permissions problems.
Open Disk Utility, in the Utilities folder in Launchpad.
Select the disk you want to check.You can verify or repair permissions only on a disk with Mac OS X v10.7 Lion installed.
Click First Aid.
Do one of the following:
Click Verify Disk Permissions to test permissions.
Click Repair Disk Permissions to test and repair permissions.
Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesn’t repair permissions for your documents, your home folder, or third-party applications.
If that does not resolve the issue, I would next verify and repair the disk with this:

Change partitions on disk with NTFS and Mac OS Extended

I have a 1.5TB external drive formatted with 3 equal size partitions: 1 NTFS and 2 Mac OS Extended formats, each one ~500GB. I'd like to remove the NTFS partition and use the whole drive for the 2 Mac partitions. Could I copy the NTFS data to one of the Mac partitions, then delete the NTFS partition, and then enlarge the two remaining partitions, of course without losing the information that's already on each of them? My system is OSX 10.7.5 -- Lion.

Probably maybe, with a fair wind & some luck…
It depends on a few factors, such as the order of the partitions on disk, how the disk was originally created, what partition scheme it uses (e.g. GUID, Master boot record…). It also depends on if all that data can be crammed into an existing partition.
I doubt you want to hear this, but it is the safest option… backup the data on every partition before you begin modifying the disk structure.
You have nothing to lose with solid backups on another disk, disconnect it to be extra cautious.
If this disk fails to repartition or you find that the 2 remaining partitions won't not expand to fill all the free space (it just happens sometimes) you can create a new partition table & start over.
Disk Utility may also complain when you try to resize or delete a partition - sometimes it waits until the last button is pressed to begin a task only to tell you something isn't possible!
I wouldn't attempt this 'copy, delete, resize' unless I could afford to lose all the data on this disk, it should work, but there is too much room for error.

USB disk with Lion recovery partition + storage partition shared by Mac & Windows: Windows can't read it.

I have a Lexar Express Card flash drive (16GB). It works the same as any USB flash drive.
I use it to move files between Mac OS and Windows 7/Bootcamp: Drag files to it in one OS, reboot in the other OS, take the files back off.
Recently, I discovered the Lion Recvoery Disk Assistant, which allows you to create a Lion Recovery Disk on an external drive (just in case). So, I decided I would use a ~1GB partition on the express card for the recovery disk, and leave a ~15GB partition for the same file sharing I am used to.
This setup requires that the disk use a GUID Partition Map with a HFS+ file system for the recovery partition, and I use a FAT32 file system for the shared partition. The partitioning was done in Mac OS Disk Utility, and then I think the Recovery Disk Assistant modifies it further by adding an EFI partition.
When I try to access the disk in Windows 7, it says it needs to format the drive first (which it shows to be a ~200MB "volume" on a disk with ~15.4GB "capacity"). From what I have been able to find on my own, Windows 7 should be fine with a disk using a GUID Partition Map, and both OSs can use a FAT32 file system. So why does Windows only see the 200MB EFI partition at the first section of the disk, and not the other partitions, particularly the FAT32 file sharing partition?
The last thing I will mention is that the disk is being seen by Windows as a MBR/Master Boot Record partitioned device. I'm assuming this is the GPT/GUID Partition Table's protective partition's fault; the one MBR partition that keeps the GPT partitioning safe from software that doesn't recognize or know about GPT.
I'm asking on the Apple discussions because it's in Boot Camp and I'm primarily a Mac user. If anyone knows a better, Windows-focused place to ask, please say so!

You really need to search first as there are A LOT of post's with the same question. Different issues with different Models.
What model/year do you have and what OS were you using first? Snow Leopard (10.6) is the last one that came with a CD/DVD with the computer.
You insert the disk when it's done installing W7 and reboots into Windows then you insert the 10.6 MacOS Installer disk for the Windows drivers. Lion does it a different way.

...........because I lost the OS X Lion install disk that came with my Mac)..........
Lion (10.7) is only a download now, there are no more physical disk's, (unless you pay the extra money for the USB installer thumb drive directly from Apple). So if your computer came with 10.7 Lion installed then you will not have a physical disk. There should be a "Repair Partition" that you use to boot to if you need to repair or to reinstall the Lion OS.

Please Help!
Thank You!!!
I don't believe the Boot Camps drivers are in the Lion download anymore, ( to keep the download smaller?), the only way you get them now is when you start BCAssistant, it will prompt you to download them onto a CD, or USB drive. You have to download and install the Boot Camp drivers separately. You then insert it when it's done, when Windows boots.

Fastest and best external hard disks for video use with Imac?

What is the fastest and best external hard disks for video use with Imac (I believe it is currently not possible to use Esata on the Imac).

For DVCam. HDV etc, I'm a fan of the G-raid drives. From personal experience they
are very solid performers. I only had one issue with a new drive that was replaced
next day. They are not the cheapest drives to be found but the build quality
is excellent. Check out:

Problem with partitioning - disk permanently falls back to old p-table

Hey Guys!
I'm quite desperate and can't find answers for the following problem - maybe some of you already had a similiar problem.
I want to reuse a SSD that I used on a different machine as primary system drive. It's partition-table:
# fdisk -l /dev/sda
Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x0004f0e5
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 499711 497664 243M 83 Linux

/dev/sda5 501760 250068991 249567232 119G 8e Linux LVM
There is a LVM volume group with two volumes (root and swap) on sda5. No matter how I try to destroy the LVM setup and the partitioning, it is always "reseted" to this setup.
I tried: lvremove, vgremove, pvremove, fdisk, cfdisk, gdisk, cgdisk, dd from /dev/null, testdisk - with and without reboots, from arch-linux booted from usb and from an ubuntu-live-cd. No matter what, the partitioning does not change.
Why I want to reformat it? I want to use the drive as cache for zfs-on-linux.
It feels like the drive is somehow write-protected.
Has anyone suggestions what to try next?

Thanks @ROOKIE
Sadly didn't work either - see below. Underneath I added results of smart-tests - maybe I miss something.

Out of disk space for Oracle 11i with Linux as OS

i want to add additional space for my server, currently i have (3) 36gb harddisk on raid 5 which add up to 108gb but since i am ran out of space for my data, i planned to add (1) 146gb though i can add 3 disk as i have 3 slots available, wont there be any complication if i add this as it is not the same with the current config? wont it affect my oracle application?

In my calculation, 3 36GB Disk under RAID5 add up 72GB. You could add your extra Disk for example on the /u01 mount point (standard for 11i apps). If you want to go for performance, you should consider another Disk with the same size and use RAID1, if that's available and hard disk mirroring is a requirement.

Problems with partitioning hard disk

Hi, I have an external hard disk with 2tb capacity.
I want to create one partition of 1,5 tb to use with Time Machine and one partition with 500 gb to use both with windows and mac.
I have partitioned the first one in HFS extended and the second one in exfat, using the GUID partition table.
Now the problem: on the mac both the partitions work well.
In Windows, on the contrary, the exfat partition is not recognized. It says it is to be formatted a nd if I try to format it (in windows) it says it is not able to do this.
I don't know what is the problem, even if I think it can be in the GUID table used...

I think you can have only one OPTION for the partition table map scheme which is for the entire drive.
So, when you created your two partitions (1.5GB Mac OS Extended - Journaled format and a 2nd for the rest of the space as ExfFat format) you chose the partition table map scheme as GUID, Windows will not see either partition. For Windows to see the ExFat partition, the partition map scheme has to be Master Boot Record.
I have never formated two different partitions like you and made the partition table map scheme Master Boot Record. I know the PC will see the ExFat partition, but I don't know if the Mac will see the other. Understand you won't be able to boot from the Mac formated partition since the drive is MBR. Try it! You will need to reformat the drive with your two partitions when you change the partition table.

RAID 1 for a Disk with 2 partitions?
