Problem mounting my disk

I installed Archlinux with the hard disk set as Compatible in the bios instead of AHCI, and now i've problems to boot Arch when I change it to AHCI.
It says something like this:
If the device "/dev/disk/by-uuid/ (big ass alpha nermeric #) is created here, try adding "rootdelay=10" or higher to the kernel command line ramfs$
I really don't know what to do.
Thanks

Perhaps you can use edit at the boot prompt in order to add the root delay to the kernel line at that point in the boot sequence.
Use "e" to start edit and move the cursor to the kernel line, make the change and enter.
Follow the instructions to continue booting.

Backups failing with error 19: the backup disk could not be resolved, or there was a problem mounting it

Hello all,
Doubt this issue relates to a recent and ugly issue but sharing anyways (resolved thanks to a user here: LaPastenague)
Time Capsule won't backup if Modem (Motorola SB6121) attached
This was on Feb 10th resolved. Few days later I upgraded to Yosemite. Backups were working fine since.
Yesterday I happen to notice my last backup was 5 days ago. I looked in the console logs and saw:
2/25/15 3:55:06.127 PM com.apple.backupd[2777]: Attempting to mount network destination URL: afp://Paul;AUTH=SRP@Time%20Capsule._afpovertcp._tcp.local./Data

I called Apple. Their front line was clueless. He suggested resetting the TC (latest "tower" model btw") which then a backup kicked off YEAH
But the next hour it failed
Called Apple again, this time to Sr Advisor. He suggested factory reset of the TC and set up again. Also first backup worked then rest failed
Third call to Apple useless also. He was asking questions I didn't feel relevant. He also was asking me to reset the TC which I told him was done 2 hours prior. He asked me to reboot which I could NOT at that time.
I begged him to collect data to submit to engineering, which will take days to get a reply.
So I thought I would throw this out to the community....
TC Is NEW (replaced from last issue). Mac is 8 months old (iMac 27"), Os is Yosemite, TC also new (latest model)
Thanks...

Yosemite is problematic on two fronts.. Networking and Time Machine.. so the combo of doing both with a Time Capsule is like bugs on bugs.
Here is my standard list.. but your problem maybe difficult to resolve.. and my suggestion is simple.. until Apple get their act together and fix TM.. buy Carbon Copy Cloner and use that for your backup. It is solid and reliable.. even better if you use USB drive plugged into the computer and do a bootable clone.. because then you have a backup that is able to be tested for full functionality 2min after the end of the backup.
This also starts from a factory reset.. but the reason for it is to change the configuration which is much more easily handled with factory reset to begin.. the instructions are there.. because this is my standard reply.. this is not uncommon!!
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the Mac itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.

Encrypted, sparse disk image stored on WebDAV server: problems mounting

My goal is to have secure, encrypted storage to back up my computer to a remote site. The remote site is an internet hosting provider who provides a lot of disk space and bandwidth, and also serves up WebDAV, for a very small price.
I have created a 100GB sparse disk image, with encryption, and stored it on the remote server. I then mount the directory containing the sparseimage (which is itself password protected using .htaccess) using WebDAV. My plan is now to mount the disk image, and use rsync to copy changes on my computer to the disk image.
This worked perfectly when I tested with a small sparseimage. It was interesting how the OS seems to buffer the changes in chunks: rsync appears to be copying a lot of files super fast, then it stalls as network bandwith suddenly throttles up for a while, and they take turns this way.
Unfortunately, after copying a few hundred MBs into the image, I am now having trouble.
First, when I try to mount the disk image, I see an enormous amount of data start transferring over the network. It literally saturates my broadband connection for at least an hour (I haven't been able to go longer yet). It seems to first download at top speed for a while, then switches to uploading at top speed for awhile. During this time, I notice that a mount_webdav process is consuming large perentages of CPU. However I can't see anything else going on at this point -- the disk image isn't mounted yet, all this thrashing seems to be from the process of the image trying to mount.
So first question: is this normal? Does anyonw know what actually happens when you issue "hdiutil attach" on encrypted sparse images? Does it have to touch and read through everything in the image once or twice? Maybe this is just a Bad Idea™
Second: the webdav server always ends up getting disconnected during this process before the image actually gets mounted. Do you think I'm trying to do something that tests, and exceeds, the limits of WebDAV?
Thanks a million for any help!
PowerBook, 1.33 GHz G4, Aluminum, 17" Mac OS X (10.4.8) The remote server is Debian

A follow up to my MS word document. I found that I created the file in MS word 2000, and I used the Apple File Security for OS 9 to encrypt it. I can't remember the password, and I do not find anything in the key chain listing.
I have Pages 08, but I don't think I can use it if I can't remember the password to unlock this old document. Is there a program to decrypt this without a password?
Thanks,

HELP ! Last To Sec . Updates causing problems-Won't mount any disk images

Just installed most current 2 updates Mac OS X v10.5.8 (Leopard) & now can't get my system to be able to mount any disk images of any kind. Internal expander gives me Mounting failed
Also tried to expand with Stuffit and got following message:
SecUpd2009-003.dmg no mountable file system.
SecUpd2009-004.dmg no mountable file system.
This first started with 2009-003 update and now 2009-004 it continues.
Also completely erased my backup external HD files.

If you did not repair permissions after updating, then try the following:
Try running +repair disk+ from your *software install DVD* and afterwards, run +repair permissions+ *from your HD.*

How do I mount a disk image that won't open?

I have an external drive Samsung 500 GB that was failing. I think my MacBook Air (10.6.8) caused it to fail because it wouldn't allow me to eject the disk even though I forced quit all programs. I eventually had to just unplug the drive and this caused the external disk to fail as it had not been ejected properly. Not my fault. It's the MBA's fault for not letting me eject the disk. Now the Samsung disk won't mount properly and I get a message that the drive is failing and I should save the data.
Anyhow, I used the free version of Data Rescue 3 to try and save the data on the failing Samsung 500 GB drive and move it onto a brand new Toshiba 1 TB drive.
I was unable to use the normal scanning function of Data Rescue 3 as the hardware of the drive was too damaged, and so I used the clone function on Data Rescue 3 to clone the data onto a non-failing hard drive, with the intent of restoring the data later.
I am not sure if I was successful in making the disk image. It hung up at the 99.6% point for about 12 hours when I decided to give up on it, and I shut down Data Rescue so I could eject the hard disks.
However, it would not let me do it. I tried force ejecting but still I could not eject the disks.
I ended up just unplugging the drives. I think the Samsung drive died almost completely then because it made a whole lot of clicking noises after that (it was only making a few clicking noises before that).
Anyhow, I plugged the Toshiba 1 TB drive into the computer again and used Data Rescue to scan the drive with the disk image on it to see if I could detect files on that drive.
It opened up the structure and I was able to see that most or all of the files were there (abbout 450GB of data) just from seeing the information about the files in the structure tree - the labels of the files (file type labels such as jpg, mp4 etc) and the size of the files, although I could not open up the files to check all of them.
I tested out the restore function of Data Rescue by downloading one file (<10MB) file. I am using the free version and can download one file for free to test things out.
It worked and I was able to save that file onto a second external drive (Western Digital 500 GB) I had plugged in. I had bought this drive just to do the data rescue.
So I think the files are salvageable and the disk image is OK.
However, when I tried to open the disk image in Disk Utility, by opening it as the source and choosing the WD drive as the destination I could not open it. I got an error message. I can't remember what the message was.
I tried just opening the disk image in Finder by just clicking on the disk image but it won't mount.
Is that because my hard drive doesn't have enough space? My Desktop on the MBA only has 12 GB free and the WD drive has only 500 GB on it even though the disk image is about 501 GB.
I don't know why the disk image is that size when the failing Samsung drive only had 450 GB of data on it.
Anyway, what should I do to mount the disk image?
I want to mount the disk image so that I can copy or move the files from it to another external drive so that I can save those files.
Is it because the WD is only 500 GB or does it mean there's a problem with the disk image I made?
Should I try Carbon Clone Copy? I use that to make backups of my MBA internal HDD though I have never used it for opening or making disk images.
I have never dealt with disk images before except for dmg files of applications downloaded from the internet.
I am trying to avoid using Data Rescue 3 as I have to pay for it and if there is a free option, such as Disk Utility, CCC or other, I want to try it to restore the data in the disk image.
Sadly, I think the Samsung drive is ruined beyong repair as it's making a lot of clicking sounds and doesn't mount properly in Disk Image and I get a message that it's beyond repair or something like that in Disk Utility.
So I am relying on the disk image I made on the Toshiba drive to restore my files.
(I think it was the last movie file that caused the problem because it was when I was trying to copy it onto the Samsung external drive, all the problems began - hanging up when copying it, not being able to eject the Samsung disk, causing hardware issues on Samsung disk and getting warning messages on Disk Utility.)
BTW, I learned how to eject a drive when it won't eject the normal way, I have to use command window and type in commands, but that's another post ....
Any advice?
I am thinking of going out and buying a second 1 TB external drive so that I have a disk with enough space to open the 501GB disk image on it, just in case that was the sole problem.
However, I am not sure that is the case, and I think there may be a problem with the disk image or I am not going the right way about opening it.
Thanks for any advice.

I think I've found the solution to this problem.
http://superuser.com/questions/19426/im-unable-to-mount-a-dmg-getting-a-no-mount able-filesystems-error
I am following the instructions here:
I ran into a similar situation. I did what simonair suggested and I received a message in Terminal that Volume mounted successfully. However It did not help me access the mounted Volume neither was I able to confirm the mounted Volume. Nor was I able to mount the image using Disk Drill or even scan through. Nothing succeeded.
Here is what I did to solve my problem. I see that in this post some suggested that we should convert name.dmg to writable file. I used the command from Terminal to convert but was not successful. INSTEAD alternatively, I used Disk Utility, attached the Volume (yes I got the same message again, ''no mountable system files'' however, Disk Utility nevertheless attached the image, which I was able to do before anyways. This time, I selected it and then clicked New image, and then selected image format read/write, not the compressed option. I created a new image. This time this image was writable however, it still would not mount using Simonair's solution. However, this time I was able to scan it with Disk Drill with exact file locations and folder hierarchy as I had. Recovering all from thereon was a breeze. Just remember: when you create new image of an attached volume and chose not compressed but read/write, you need to have a disk with exact amount of space that totals the total space allocated within that name.dmg file (not the amount of space the data takes). Mine was huge, and luckily I had an external disk with enough space to do that and it took about 5 hours for about 400GB of disk allocation. Good luck.
And so far it seems to be working. Even though the volume is grayed out on the left side of Disk Utility, I am still able to select it as the source for making a new disk image. I chose Read and Write and no compression.
The only thing I might be doing differently is that instead of choosing the disk image as the source, I chose the volume as the source. The volume is grayed out, but the disk image is not.
It seems to be working all right. Keep my fingers crossed.
If this doesn't work, I will use Data Recovery 3 as a last resort.

Time machine: An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.

Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:
An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.
Yesterday, I opened Disk Utility and verified the disk. Got this error:
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

You have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

Why won't my external hard drive mount in Disk Utility even when it shows up on the list?

Hey all,
For the last few years I've used a Samsung S2 1TB external harddrive to back up all my files, this includes photos, music and a vast amount of resources required for Uni. However I plugged it in for the first time in about two months and discovered that neither my Macbook Pro (late 2011) or my Mac Mini (early 2013) are able to mount the hard drive.
It shows up in Disk Utilty however the harddrive is greyed out and when I manually try to mount it I get an error message saying that it can't be mounted and to use the first aid 'Repair disk permissions' feature which would be all good and well were that not also greyed out.
I've read a fair amount on this forum that suggest that Mavericks has caused quite an issue with harddrives and although I don't know for sure, the harddrive did stop working at a very similar time to when I updated. I've sinced used the basic version of 'Disk Drill' on the harddrive and all the files show up perfectly which leads me to believe that perhaps the issue isn't with the harddrive itself but perhaps a compatibility issue.
I was just wondering whether anyone had any advice or had suffered a similiar issue, preferably in relation to the Samsung S2 harddrive. The partition type is a Windows_FAT_32 and it's a USB hard drive.
Thanks in advance!

Because there's a problem with the disk's directory structure; these are often the result of improperly unplugging drives or forcing a computer to shut down. Proceed as instructed, or try using a more powerful utility such as DiskWarrior to repair it.

Internal hard drive does not mount in disk utility

My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each: Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
Then consider a later version OS X -- whatever most recent version that model can support... {edited}
Good luck & happy computing!

IPod 4G always mounts for disk use when Mac wakes from sleep

My 4G iPod is always mounting for disk use when my Mac (10.4.8, Dual 1.8 GHz G5) wakes from sleep, even though the settings for the iPod has "enable disk use" unselected. When I launch iTunes (latest version) the iPod promptly is unmounted. I have restored factory settings, I have reinstalled the computer's OS and iTunes with it.
What is going on and how can I make it normal?
Dual 1.8 GHz G5 Mac OS X (10.4.8) iTunes 7.1, iPod 4G 20GB

UPDATE:
I have started to turn off Bluetooth at night before I put my computer to sleep. I HAVE NOT HAD THE FIREWIRE RANDOM DISMOUNT PROBLEM SINCE. I do not know if this is a freak coincidence -- but so far, so much the better for my firewire drive.
Hope this helps someone else down the line... eh hem...

Missing menu "File|NFS Mounts" in Disk utility

I had many NFS mounts using Disk utility and I used "File|NFS Mounts" but now that option is missing and I can't see my mounts neither those mounts are working, so I have two questions
1. Where I can see my old mounts listed?
2. How can I make nfs mount work?

The problem is Boot Camp: It uses a hybrid GPT/MBR partitioning scheme - which ends up hiding the Recovery HD partition - which is an EFI physical partition (neither GPT nor MBR).
I would expect a new version of Boot Camp to release - like real soon - because of the Recovery HD partition invisibility issue.
In this article - it is suggested that rEFIt should be used to partition a hard drive that is going to support multiple boots including Mac OS X, LINUX, and Windows.
(http://wiki.onmac.net/index.php/Triple_Boot_via_BootCamp)
The key in the article to using Boot Camp with rEFIt is this:
"Run the Boot Camp Assistant and create the Windows XP driver cd. Then exit Boot Camp. DO NOT PARTITION USING BOOT CAMP: you are only using Boot Camp for the drivers, not the partitioning."
All partitioning is done in terminal mode using the "diskutil" command.
rEFIt is used to update both the GPT and MBR records so that all partitions will be visible using its "gptsync" command.
Then - you replace the standard Mac boot menu with the rEFIt boot menu. THAT will show the Mac OS X partition, Recovery HD (an EFI partition), and the Windows partition.
My caveat is that rEFIt - which is open sourced and available here: http://refit.sourceforge.net
has not been recently updated and tested with respect to Mac OS X Lion.
Hope this helps!

Can't mount USB disk with the atribute of fix and read-only

Hello All,
I have a usb disk which is set as fix(non-removalbe) and read-only. I tried to connect it to Macbook version 10.4.11 ,but it failed to mount the disk. However, connecting to 10.5.X and windows XP work fine. I am wondering is it a bug specifically in 10.4.11 only ? Could I get any patch for this problem ?
Thanks,
Ying

HI Ying and Welcome to Apple Discussions ...
Try repairing disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac.

Yosemite cannot mount external disks

Since I upgraded to Yosemite my IMAC does not mount external disks, even the bright new one I bought
I have also a Macbook Air that I upgraded to Yosemite and these same external disks can be mounted on the Macbook Air.
I have searched on the Apple support community and on the internet and quite some people whom upgraded to Yosemite have the same problem.
I checked the USB specs on both the IMAC and the MACbook Air
IMAC :
     Hostcontroller : builtin userinterface
     OS hostcontroller : AppleUSBEHCI
     PCI- code : 0x3b34
     PCI revision code : 0x0006
     PCI factory code : 0x8086
     Busnb : 0Xfd
MACBook Air:
     Hostcontroller : builtin userinterface
     OS hostcontroller : AppleUSBEHCI
     PCI- code : 0x0d9d
     PCI revision code: 0x00a2
     PCI factory code : 0x10de
     Bus Nb : 0x24
Needless to say that I need the data stored on the external disks.
Thks for helping me out.

I have read that if you turn Spotlight off you will have no problems. Open Spotlight, choose "privacy", click the "+" at the lower left and add what you do not Spotlight to search. Worked for me. I have 2 internal Seagates formatted OS X journaled in an external case.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari's location bar, Mail's message view, and the dialogs for mounting encrypted disk images.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari’s location bar, Mail’s message view, and the dialogs for mounting encrypted disk images. Is there any solution to this problem? Also diabled the Smoothing in the SystemPrefs and also via Terminal. Font smoothing is still there. Very annoying, especially in PDF attachments in Apple Mail.

Try feeding Safari a user-defined CSS file with font-smoothing tweaks (including none). The filename and its filesystem location are arbitrary. Use your favorite coding editor.
Safari > Preferences > Advanced > Style Sheet:
Here is an example with all elements uncommented. Pick the one that works best for your Safari viewing and comment out the others:
Preview. Try Preview > Preferences > PDF > Smooth text and line art (uncheck)

Problems with ntfs disks

I need to mount ntfs disks in oracle linux 5.8 , I follow the intructions in other thread in forum but i can't mount the disk, when I use mount command there is no error but when i try to open the directory where was mounted disk, terminal throws this:
# mount.ntfs /dev/sdb1 /media/ADATA
# cd /media/ADATA/
bash: cd: /media/ADATA/: Resource temporarily unavailable
I can unmount disk normally but i can see content of my disk .
I want some help please thanks.

Sorry, but I think troubleshooting the problem based on the error message is pointless. It's not an error message generated by the NTFS driver or points to a specific or well-known problem. There can be numerous reasons. If you need help to troubleshoot this problem, please provide information how to reproduce it.

Leopard doesn't mount the disk with time machine backup!

Hi friends. It's my first time in this forum, and I'm sorry by now for my poor english.
My problem: One week ago I had some problem with hard disk, but after a visit to an Apple center and after a replacement of my disk the problem was solved.
Now I want to restore all my file and my system preference from an external hard disk (USB LaCie 500GB) when have made a complete backup with time machine.
But Leopard doesn't mount the disk in finder or in Utility Disco. I see it only in System Profiler. I try with my old iBook with Tiger and it mount correctly the disk! It's amazing! Please Help me, I need my file on my iMac for work!
Thanks and merry Christmas!!!

Similar thing for me as well. I however haven't made a backup using Time Machine.
In preparation for Leopard, I reformatted my laptop's hard drive and installed Mac OS X 10.5.1 fresh. As soon as I plugged in my trusty 500GB external WD MyBook Pro (trying both Firewire 400 and 800 on my MacBook Pro 17"), I get the following alert:
"Disk Repair
The disk "500GB" was not repairable by this computer. It is being made available to you with limited functionality. you must back up your data and reformat the disk as soon as possible. OK"
Keep in mind, I run Disk Utility and "Repair Disk" and "Repair Permissions" religiously every week and have had no issues while running under Mac OS X 10.4.11. My other laptop running the 10.4.11 doesn't report any issues with the drive at all - only when I plug it into this one running 10.5.1.
Is there a firmware update for this drive? Is this Apple's issue? I have another LaCie Firewire drive and it works flawlessly even under 10.5.1.
Right now, I can't even use the drive as it's Read Only (due to the error).
In system logs:

The drive is reported to be "Ok" when running Disk Repair on other machines not running Leopard. As a test, I just "upgraded" my wife's laptop to Leopard and now I have the same issue on that machine.
Help.
