Leopard Disk Utility repair on disk with Tiger partition?

I'm trying to repair a disk containing a bootable tiger partition using disk utility in Leopard and getting a "can't unmount disk error". Suggestions?

After not being able to unmount the Tiger partition it went through and tried to fix my Time Machine partition and gave me this error:
Invalid Index Key
The volume Time Machine could not be repaired after 3 attempts
Error filesystem verify or repair failed
Should I restart and try repairing it again? Do you think I'm getting that error on the TM partition because it couldn't unmount the Tiger partition or is my brand new TM disk hosed?

Encrypting an external disk with two partitions

I have a large external disk that I'm going to be using for Carbon Copy Cloner backups. I want the disk to have two partitions, and I want the whole thing to be encrypted with Full Disk Encryption. Should I (a) first partition the disk and then encrypt each partition, or (b) encrypt the physical disk and then partition the result? I think (a) is the best path (it looks like it's at least possible), but advice would be appreciated -- thanks!

Hi,
according to this http://support.mediafour.com/entries/170474-macdrive-compatibility-with-hard-dis ks-with-multiple-partition-types-i-e-dual-format that 'feature' is currently not supported by MAcDrive.

Mirro Raid can you use a single 4TB disk with 2 partitions for mirrored raid ?

Hello,
I have a new 4TB hardrive.
After lots of reading, i was thinking that i could partician the drive to 2 (2TB) Then create mirror raid.
Essentially thinking that i would have photos on one of the (2TB particions) and they would mirror on the other ?? as a double copy storage.
I can partician okay and the try to drag the two particians onto the "mirror raid set" and ithe following message displays :
"Can't add Seagate expansion disk" to the raid set because another volume from this disk is already part of the RAID set"
I'm now thinking i need to purchase another 4tb hardrive for this to work ?
Or if you "mirror raid set" is it actually particioning the drive and creating a copy ?
Forgive me... i'm not really very up skilled with disk utility, and basically just don't understand.
Looking forward to some help and advise
warm regards Tracy Gr

It doesn't make any sense to mirror on the same drive. The idea behind mirroring is that should one disk in the raid set fail your data is safe on the other disk. Mirroring to partitions, if it's even possible, would only bring you disaster when the drive fails because you would lose the complete raid set and all of your data. If you insist on mirroring buy another drive.

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.

Mirror boot disk with soft partitions

We've been investigating Solaris Volume Manager with Solaris 9 and have some questions. We currently use DiskSuite 4.2.1 to mirror our boot disks on Solaris 8. The fact that SVM is integrated into the kernel on Solaris 9 got us thinking. Here are some questions I would greatly appreciate answers to:
1. Is it possible to have your boot disk partitions (/root, /var, swap) be soft partitions and then mirror the soft partitions (so disk 1 you'd have 3 soft p's and on disk 2 you'd have 3 soft p's and create the mirror from them)?
2. What would the problems be with this? The major one we could foresee is not being able to see your /root, /var and swap partitions in the case of having to boot from the CD, but if SVM is in the Solaris 9 kernel, wouldn't that solve that issue. Is this a problem? Are there other issues/problems we're not thinking of?
3. Finally, is having your boot partitions be mirrored soft partitons a supported configuration from Sun?
Thanks,
Bob Jones

The reason the HDD is split into two partitions is so if there is an error with the OS, they can reinstall it without affecting the user files.
Makes sense in a way. But does this 'they can reinstall...' imply that you don't have the OSX Install DVD for your Mac ?
Cause you need that DVD for installing the BootCamp Drivers of it !
I do have admin, and I can re-partition my HDD, but I cannot touch the OS partition.
If I set it up like this: http://micmac95.fileave.com/HDD%20setup.png , by shrinking the USER partition, will I be able to install windows on the BOOTCAMP partition?
Personally I never tried this 'Shrinking one partition to make another partition' approach with BootCamp.
But, if you don't have one now is the time to make a complete backup of all the things on your Mac !
Before 'fumbling' with partitions I always make sure to have a backup.

Multiple disks with identical partition names

(cross-posted from the Mac Ach:)
Just a day before the announcement of the FW800less BunnyBooks, I bought me an FW800 external, to boot my PB off while working at home.
I intend to clone my internal to it, keeping the same organisation in which for instance I have partitions OSX1 (root) and OSX2 (case sensitive), with a softlink work -> /Volumes/OSX2/Users/bertin/work in my home directory. Rather than calling my external partitions OSX1e and OSX2e (for instance), and having to modify all my links, I'd prefer to call the external partitions OSX1 and OSX2 too. (This means I could keep the 2 disks synchronised easily.) OS X handles this correctly by changing the mountpoint name in /Volumes on the fly.
My question is about the mount order during booting. When I boot from the external, its partitions will be /dev/disk0s*, but does that mean that /Volumes/OSX1 and /Volumes/OSX2 will be guaranteed to point to the external disk's partitions (and to the internal disk's when booting off that one)?
Thanks,
René

Format - analyze - purge a disk with mounted partitions

I'm trying to format a machine with multiple disks. To do this, I've been instructed to run format, then analyze, then purge on each of the disks. Unfortunately, each disk has at least one mounted partition and when I try to run purge, I get the following message:
"Cannot do analysis on a mounted partition."
I've been able to get around this problem on all but one of the disks by using umount and making appropriate edits to /etc/cfstab. That said, I'm stuck on the first disk where mounts like / and /var exist. It's my understanding that you can't unmount / - if this is the case, how do I purge the disk where / is mounted?
Thanks,
David

You do realize the end result is that you will have no usable OS, right? If you do that's fine but I wanted to put that out there.
Reboot from install media and run the commands from there. They will be in the single user environment.

Cannot Load Leopard due to Historic Unresolved Problem with Tiger.....

When I installed Tiger some years ago, my computer (iMac) refused to shut down normally. I tried many times to get an answer from Apple without results. Since then I have had to shut down by holding the start button. OK. Inconvenient but it worked. Until I tried to install Leopard. Since Leopard requires a Restart and I cannot Restart from the menu I cannot install it. I left messages on Apple's Support e-mail which promises to get back in 48 hours. This was a week ago and I still have not heard from Apple Support. Any thoughts about resolving this issue?
Here is the error message that the system sends to Apple:

Excellent move. The general rule is to never install any software at all on a computer that is not working properly. At best it will still be broken, at worst it will die completely
I am assuming your old Tiger was an upgrade from an earlier system and not an install on a blank HD. Usually that kind of problem requires an erase (full, not quick) and install and then a careful migration from the backup, one program at a time, in case the problem is related to an old piece of SW.

Backup Leopard Disk on Single Layer DVD

I have a leopard disk with the original 10.5.0. I want to make a copy on a single layer disk. I followed the instruction here: http://www.scribd.com/doc/431468/Guide-to-making-a-SLDVD-Leopard-install-disc
Everything works fine without a hitch. After I burn the disk it mounts fine and appears bootable in the startup preference pane, however, when I attempt to boot from it, (by restarting and holding the "C" key or holding the "option" key to select the disk) it does not appear as bootable. If I hold the "C" key it sounds like its scanning the disk, then it just boots from my hard drive. Also, if I hold the "option" key, only my OSX and Windows partitions appear, not the inserted Leopard copy. Please NOTE FOUR things, I want to have this on a disk, so please do not suggest restoring to an EXT HD or flash drive. Also, I have attempted the burning process with Disk Utility and Toast. I am using DVD-R disks and 10.5.7 on a Unibody MacBook Pro
Thanks for the help,

Since this is not supported by Apple, I suggest you contact whoever published this and ask them why it does not work.
Your self-imposed limitations preclude doing it correctly.

DO NOT install Airport Extreme update 2008-4 if using usb disk with TM

I have Airport Extreme and a WD 1TB disk with two partitions connected to the Extreme. Other partition just for stuff and the other for Time Machine backup.
Today I installed Firmware update 7.3.2 and disaster struck. I noticed that Airport Extreme was reporting a disk problem. I disconnected the drive from Extreme and use the Disk utility to find out what is the matter. The partition used for backup needed repair, but couldn't be repaired. I had to format it.
The worst thing (besides losing all my TM backups): After I got the disk formatted, I checked TM. It wasn't possible to do Time Machine backups any more for a USB disk connected to Airport Extreme.
Anyone else have the same?
I strongly recomend NOT to install the update if using Airport Extreme + USB disk for Time Machine.
I'm really dissapointed if this is an issue connected to the update 7.3.2.

Hello
I'm having issues too wtih the drive connected to my airport extreme basestation but not the same kind.
Sometimes (5 time a day) the airport extreme doesn't respond anymore and it doesn't appear in the airport utility. Then every body is disconnected from internet (even if the light stil green...).
I have to reboot the basestation manualy.
I also have two partitions (datas and TM). I'ts very anoying th only solution i found right now is to unplug my drive...
Hope Apple will fix this ASAP ...

Can I use the Leopard Disk Utility to repair a Tiger partition?

I have a multi-partition external disk, one partition has Tiger installed on it, while others have Leopard. (I used Leopard to partition the drive and then used SuperDuper! to copy my earlier Tiger backup from another disk to this disk.) Now I find I have errors on the partition with Tiger. Can I use the Disk Utility tool from my Leopard install to repair the Tiger partition? Earlier today I tried to boot from my Tiger install DVD and use the Disk Utility there to repair the partition, but it just hangs up and won't go forward.
thanks,
Chris Altwegg

You could use it, but if Tiger's Disk Utility couldn't fix it, it's doubtful Leopard's would fix it as well. You're better off using Disk Warrior from Alsoft.com.

Can I repair a Snow Leopard disk from a Tiger machine?

I had the hard drive go down on a MacPro with an Intel processor running OS 10.6.4. When I try to boot, it gets to the Apple screen and shuts down. Running the disk utility from the installation disk gives me the error:
Checking HFS Plus Volume
Invalid Extent Entry
Volume Check Failed
I pulled the drive and connected it with a USB adapter to a spare Mac G5 with a PowerPC processor running Tiger 10.4.11. I can read the disk on the G5 with Tiger. Disk utility on the G5 gives me the same error when trying to repair the disk.
Are there any utilities out there I can run on Tiger to repair the Snow Leopard disk? Free if possible?
Or a good OSX utility that will let me image the drive to another hard drive? This is a production machine in a printing environment and I need to get it back up and running as soon as possible.
Thx...
Carvelli

I could not repair the disk from the command line either. It gave me the same error messages. I did not try Carbon Copy Cloner...yet. I had an extra 250GB drive which I re-installed 10.6.4.
I can bring up the old drive on the USB adapter, so I am going to try the Mac Migration Assistant. Which I've never done before. Does anyone know if it bring over all the applications during the migration? Or will I have to re-install all the applications over again?

Can I run hardware test and repair a disk with Leopard using 10.3 DVD

Hi,
I'm trying to decide whether to partition and clone Leopard to my external or partition and install Tiger on the external.
My iMac came with 10.3.6 install and hardware test DVD's and they (Comp USA) gave me a Tiger drop-in DVD. I upgraded to Leopard through a family pack DVD (when I told my friend I would by one of the install's I thought I would get a DVD, but you only get an install license, oh well). By the way, Leopard runs great in my rev A iMac G5.
I'm trying to figure out which os to use on the external as a safe-boot incase something happens. If I clone Leopard onto a partition for backup/boot, can I still use the Disc Repair (not permissions) and Hardware Test from the 10.3 or Tiger DVD's to maintain that permission should something bad happen? The way I see it, i'll be able to repair permissions on both the main and external drives using Leopard's disc utility, but I'm not sure if I can repair a Leopard disk or do Hardware Test on that disc using an earlier version of OSX install/Hardware Test DVD's.
Will earlier versions of OSX repair a Leopard disk and be able run Hardware Test?
Thanks for the help,
LowBb

Yes, that seems to be the case, but I didn't do good enough research when he asked if I wanted a license for Leopard. For some reason, I had it in my mind that a Family pack came with multi DVD's for people. Maybe that's why he sold me a license so cheap. I thought I was getting a bargin, you get what you pay for.
So, I have the hardware test DVD's that came with the iMac and the Tiger drop-in is just an upgrade with no Hardware Test, you are correct.
But: (let me make sure I have this right) I should not use the 10.3 DVD's or the Tiger drop-in to repair a disc (not permissions) on a hard drive running Leopard. Is this what you are saying? I kind of thought this would be the case. If it is, I'm going to install MY stuff that I have the DVD's for on the external as an emergency boot disc.

Disk Utility: "Repairing disk failed with error Could not unmount disk"

Disk Utility: “Repairing disk failed with error Could not unmount disk”
Hi. I’ve been experiencing some mildly squirrelly behaviour with my system (vide infra) so decided to repair the two internal hard drives on my computer. The primary hard drive is a 74.53 GB ST380013AS that came with the system; its S.M.A.R.T. Status is “verified” and Disk Utility repairs permissions just fine. However, the second internal drive (Maxtor 6L250S0, 233.76 GB, lower Bay, Journaled HFS+), despite being verified by S.M.A.R.T. status and apparently running OK, fails to unmount when I ask Disk Utility to repair it- I get the above error message in red. I have repaired this disk with DiskWarrior (v3.03) and all appears to run AOK. Can anyone tell me why I cannot get Disk Utility to run on this secondary (eg, non-startup) disk? I have tried many times and the error is reproducible. Thank you!
G5 1.6GHz PPC, 1 GB RAM, running OS 10.4.6

Thank you for these useful links!
For others who have this issue, I also found very helpful advice given to this question on the MacFixIt forums by MicroMat Tech3 at
http://www.macfixitforums.com/php/showthreaded.php?Cat=&Board=tiger&Number=76265 1
He said: "Use the lsof command to find the open files on a volume that does not unmount or eject. Open Terminal, located in /Applications/Utilities. Type: sudo lsof | grep Leave a space after the p in grep, then drag the icon of the problem volume to the Terminal window. The pathname for the volume is pasted in for you; press Return. Then enter your administrative password at the prompt, and press Return."
At this point, one now has a list of the open files/processes on the volume that will not unmount. You can use Activity Monitor to terminate these processes if you wish, and then the volume will unmount as it should.
