Blocksize error during Disk Utility encryption reformatting

So I was erasing-and-reformatting an external hard drive so that I could encrypt it (it's through Disk Utility, so I suppose that means FileVault, right?), when I get the attached error. It sounds like it's either some kind of internal incompatability within the encryption or a buggy version of the encryption algoritm or something, because padding? But... that's really unlikely, of course. Thoughts? Has anyone seen this before?
Thanks! : )

Update: I called Western Digital and they say this error is caused when one of the sectors of the hard drive is damaged in some manner (they didn't elaborate, but I assume it's some sort of physical corruption). So, if you have the same error, chances are you'll need to replace the drive.

Disk Error during Disk Utility Repair Permissions

I was wondering if anybody else has experience a Disk Utility Internal Error while repairing the permissions on their system disk. What did they do to correct this issue?
A snapshot of the error can be viewed at:

Thanks in advance.

I sympathise if you are on dialup! Here is the post you need (originally posted by Mac Fool):
Just to catalogue the solutions listed above
Here's what I did, and it worked fine.
1) Move iTunes onto the Desktop.
2) Run Disk Utility
3) Go to HD>Library>Receipts and trash all iTunes .pkg files EXCEPT for iTunesX.pkg and iTunesPhoneDriver.pkg
4) empty Trash.
5) move iTune from Desktop back to 'Applications'.
Hey presto. you should now be able to repair permissions again.

Just as Beavis posted above
BTW, the link "here" does take me directly to the post, but clearly it loads the entire topic first.

Lion Install thinks that the system disk "Macintosh HD" is not Mac OS Extended (journaled); it is. Exactly what do I do in Disk Utility to "reformat" the disk, I don't see that listed on the menus.

Error Message, during installation of Lion; “This disk is not formatted as Mac OS Extended (journaled). Use Disk Utility to enable journaling or reformat the disk.” The disk I selected to install OS X on, was the only one listed, “Macintosh HD”. The results of a Disk Utility check are; Format: Mac OS Extended (journaled), Name: Macintosh HD. There is a fresh Time Machine backup. The computer was Restarted and installation attempted again - same result. I have downloaded Lion a second time, and tired install again, same results. The computer is a December 2007, iMac 24” with 2.4 GHz Intel Core 2 Duo, 4 GB Memory, s/w version 10.7.5; Disk Capacity 319 GB, Available 117 GB. Macintosh HD has alway been the system disk, does it now have an identity crisis? Would reformatting the disk mean Erasing it? Exactly what do I do in Disk Utility to “reformat” the disk, I don’t see that listed on the menus. This computer is getting cranky, I no longer Shut Down at night, only Sleep. If it’s Shut Down, the next morning I am treated to a white screen, for a long time, before it finally shows me the Log On Screen. Suggestions would be appreciated.

RRFS - This took me a long time to finally get to a fix. Your reply led me to investigate the Repair Disk Partition - as it turned out there wasn't one; the HardDrive was going bad slowly. The 10 to 40 minutes it took to startup in the morning, was the HD trying to find it's way. I had the 320GB HD replaced with a 2TB HD. All is OK now. Thank You very much!! Also, the Apple store geeks couldn't make it better but the locally owned Apple retailer did just great with it. from San Luis Obispo County - Peace.

Drive has reported a fatal error to Disk Utility, HELP ME PLEASE!!!

I'm a little worried my Macbook Pro has become an overpriced paperweight.
Here's what happened:
I had a spare 512MB RAM, which was taken out of my 24" iMac Intel Core 2 Duo when I replced it with a 1GB RAM and, after checking several sources on the web, successfully installed the extra RAM in the MBP.
I restarted the MBP and the new RAM was registered after checking in About this Mac. I then began using the MBP as normal and wrote and saved a Word document. I clicked on the email and Safari icons in the dock and they just kept bouncing in the dock without launching. Pressed Power button - nothing. Took out the battery and replaced it after 30secs and pressed power button. All I got was the grey screen with the Apple logo and the winding circle which stayed like that for 20 minutes.
First reaction was to remove the RAM and restart. Same endless grey screen and winding circle.
Rebooted from CD, checked disk and repaired and said everything was OK. Restarted without CD still nothing.
Tried Archive and Install and came back with an error during installation.
Tried Erase and Install - same error.
Tried to select startup disk and it no longer could find my HD yet Disk Utility could find it and told me everything was OK. Tried resetting PRAM nothing.
Tried to erase the HD and nothing happened. Erasing a HD takes some time, but everytime I hit erase 10 seconds later it was back to the same point where I began
Next tried to create one single partition and struck the message Drive has reported a fatal hardware error to disk utility. Even the lettering for the main drive is now in red.
Do I need to replace the hard drive altogether or is there a solution to this problem. Was it the RAM that brought me undone or was that just a coincidence?
PLEASE HELP ME!!!

make sure that you haven't used it yet as RAM can only be used in one machine, not transferred to another one (like you did).
Sorry, but that's completely untrue, and I don't know where you might have read or heard such a fallacy. RAM has no registration that even tells a system that it's been used, much less a key that would make it work only in one system. As long as the RAM is properly compatible and precautions are taken not to shock a system with static electricity while removing or inserting the component or causing mechanical damage, a RAM module can be swapped between systems as often as desired.

Endless errors on disk utility

My 2nd internal hard drive in 2.5 years just died on my iMac G5. Apple is coming on-site to fix. During the 1st hard drive death, I installed the operating system on an external drive and was able to work from that drive. I assume this was legal since I was discussing all these things with AppleCare as the int harddrive died (over the course of a week of AppleCare calls). Doing this allowed me to save a substantial amt of data. Since then I have used this drive as a backup drive, rathern than as an operating system.
Now, I'm trying the same thing with the 2nd internal hard drive death. After booting up to the external drive, the first thing I did was upgrade from 10.4 to 10.4.8. I restarted the computer using the exteral drive. The Mac OSX setup assistant wouldn't connect. I tried to disconnect and it wouldn't disconnect, either. I Force Quitted out of the setup assistant. The 2nd thing I did was run disk utility and verify permissions. It said I had no valid packages. I copied BaseSystem.pkg and Essentials.pkg into the Library. Now disk utility gives me absolutely endless errors, all of them "User differs on..." followed by "Group differs on..."
Since this is mainly a backup disk, all my files are under ExtHD/ rather than a user. I don't know anything about packages--I read the above on an earlier post and it got rid of the "No valid packages" error on Disk Utility when I first ran it. I don't know anything about receipts, etc. About the only thing I know is that I have two libraries, one for the main hard drive and one for the user.
I'd like to keep this external drive as a bootable system. I want to be able to run Disk Utility to clean it up. Any suggestions?
iMac G5, MacBook Mac OS X (10.4.8)
iMac G5, MacBook Mac OS X (10.4.8)

So I can do an archive and install, and then when the fresh Tiger is on there, would I upgrade to 10.4.8 right then? Then I suppose I copy all my backed up files to the correct user directories?
How much memory do I need on that hard drive to archive and install? I'm assuming it archives on the same hard disk. Does that mean I have to have less than 1/2 of the memory used, so it can back itself up, or does it erase old data as it archives, freeing up memory space?
Thanks for your input!

Disk Management Tool error in Disk Utility

Update: (first, reviewing problem that I and others have been having, including on 10.4.x systems):
When I attempt to repair permissions on my HD with Disk Utility, I get this specific error message: "Disk Utility internal error -- Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility" and the repair-permissions will not proceed. It fails to get the proper "correct" permissions info for that drive to allow the repair. The error log points to a file in the Library called "DiskManagementToll" The path is ~/System/Library/PrivateFrameworks/DiskManagement.framework/Resources/DiskManag ementTool)
This problem is appearing in many forums here and elsewhere, including 10.4.x systems (like mine) and persists in a few after deleting suggested files. Is there a sophisticated solution that addresses the problem through the DiskManagementTool file by replacing some values or replacing the file from a backup vis SUDO or Root?
Previous posts have focused on Macs running 10.3.x and with iTunes 6.0x installed. Not here, so the problem is more general. None of the "delete iTunes / plists / Chess.app" suggested fixes have worked for me. Also tried running DU from my Tiger install disk; no luck! -- still fails when it tries to determine the correct permissions.
The "DiskManagementTool" file apparently either stores the correct file permissions or handles reading them from the receipts in the Library. If I understand things right, Disk Utility is actually a (user)-permissioned graphic front end, while DiskManagementTool is a Root-user-level tool that actually does the heavy lifting. Can I replace -- and any benefit to that -- or rewrite it with proper access?
There is a complete crash log report in Crash Reporter, by the way. Anyone want the text, and would it help figure out what's happening?
I've tried the suggested deletion of iTunes 6.0.2 or Chess.app and their plists (these and other steps were suggested on MacFixIt at http://www.macfixit.com/article.php?story=20060111090035797 the advice is, basically, to delete iTunes 6.0.2 and/or Chess.app and related plist files.) As I said, no luck!
Everyone that I talk to says it MUST be the fault of some other 3rd-party disk utility software.
For what it's worth, I HAVE run Disk Warrior -- and, the drive that's having the problem is a recent reinstall from a backup using Carbon Copy Cloner. The original disk is NOT having such a problem, only the hard drive on my iBook after the reinstall. Don't know if that gives any clues (or to how the link gets somehow disengaged between Disk Utility and the Disk Management Tool file / software).
Any thoughts on that? What about replacing the Disk Management Tool file in the Library or forcing some kind of re-link to it? some Unix guru MUST know a fix!
Obviously, the big worry for me is that I can't update my System to 10.4.5 or anything else without repairing permissions first. This IS a big deal. And others are having the same problem. Help?!?
New 2 GHz dual g5 , Dual g4, & iBook G4 (recent) Mac OS X (10.4.4)

A system problem was involved that became, briefly, a "known issue" that was solved in the next minor update. Solved, anyway, by the advice given by the last poster. Thanks! SJ

My HD needs to be reformatted according to Disk Utility, but even when I use an external device for startup, Disk Utility cannot reformat the HD

I have a Macbook with a 500 GB Hard Drive. A routine check on Disk Utility told me the disk needed to be reformatted. I restarted from an external USB drive, but when I try to use Disk Utility to repair the HD or to reformat it, Disk Utility is unable to do anything with the HD (cannot repair, cannot erase,cannot reformat the HD). Is there a utility App that can help me with this, or is the HD unrecoverable?

Hi
Thanks very much for your reply. We have been starting up from a backup (USB) drive and use the disk utility that is on the backup drive so the internal (problem) HD is not being used for anything (except for wanting to repair it). Still Disk Utility cannot reformat or repair the drive. I have also run Onyx but it tells me everything is OK on the drive.
But I have made a little progress. Using my old install disk for Snow Leopard (10.6.3) I have managed to do a fresh install of the system on the internal HD. Unfortunately, I also asked the install disk to transfer/migrate the settings and documents from the backup drive back onto my internal HD. The install appeared to work, but then it got hung up on copying the documents from my backup drive to the HD. After letting it sit for 2 days without going anywhere, I stopped the install process. I am going to try again, just using my Snow Leopard CD to install Snow Leopard, and nothing else. If that works, I will then get on to the problem of copying the rest of the settings and documents from my backup.
But since the Mac works OK off the USB backup, and will also run off the install CD, I am guessing the problem is with the HD and the only solution might be to replace it if I can't repair it. But the macbook is several years old, and I am not sure it is worth buying a new HD for it.

Reported Fatal Hardware Error to Disk Utility

I see the following message in my Power Book G4 Disk Utility:
"This drive has Reported Fatal Hardware Error to Disk Utility. If drive has not failed completely, back up as much data as you can and then replace it with a new drive."
I already made a back up my Home folder to my external HD. The install disk utility reports the same and has grey the repair uptions.
The spinning beachball appears constantly when using Safari and iTunes. What should I do?

If your Mac is no longer under the standard 1-yr warranty period or under the 3-yr extended warranty if you purchased the AppleCare extended warranty for your PB, you need to purchase a new internal hard drive that is compatible with your Mac model. This is something you can install yourself or take your Mac to an Apple authorized repair facility to purchase and have a new internal hard drive installed.
The repair facility should include re-installing whichever OX version and all software that was pre-installed and shipped with this Mac when purchased new. If this wasn't Tiger and you purchased a Tiger retail install package, you can re-install the Tiger upgrade yourself and then replace all data from your backup on the new hard drive.

Errors in Disk Utility

Hello. I was wondering for some opinions. i was having some problems with permission errors in disk utility so they wanted me to erase and install with a new disc set. So I completely erased the disc and reinstalled just the software on the mac os x discs. Now, after running typical software update and now I have 492 pages of permission errors. I ran it three times so far and it is still coming up with 492 errors on it.
What could be causing this?

Hi,
*"i was having some problems with permission errors in disk utility so they wanted me to erase and install with a new disc set."*
Who is they? Apple?
You have 492 pages of permissions messages or 492 messages?
It won't do any good to keep running it. Go here for information on permissions you can ignore. http://support.apple.com/kb/TS1448

Disk utility and reformatting for an external portable hard drive

I bought a brand-new iomega ego portable hard drive (USB compatible). When attempting to format it, I went to 'disk utility' to erase the drive. The drive appears, with the following information listed: Mount Point : /Volumes/Iomega HDD Capacity : 465.8 GB (500,105,217,024 Bytes)
Format : Winows NT Filesystem Available : 465.7 GB (500,022,378,496 Bytes)
Permissions Enabled : Yes Used : 79.0 MB (82,838,016 Bytes)
Number of Folders : 0 Number of Files : 32
Obviously, it needs to be reformatted. But when I click the erase tab, it will not allow me to pick the volume format or name (it just has it listed but unselectable).
Any suggestions on using disk utility or reformatting the drive so I can use it will be useful!

The drive has been pre-formatted for NTFS. You need to do the following:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to APM then click on the OK button. Click on the Partition button and wait the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

My external hard drive accidentally switched off during Disk Utility's "erase free space" process. I restarted the external hard drive and Disk Utility, but now I get the "couldn't mount disk" error when trying to finish the erase. Please help!

My external Lacie Quadra hard drive accidentally switched off in the middle of "erase free space", and when I switched it back on Disk Utility was hanging. So I Force Quit Disk Utility and restarted it. Now when I try to erase I get
"Secure Disk Erase failed with the error: Couldn’t unmount disk."
But "erase free space" seems to work...
What can I do? I'm erasing as I'm giving the drive to someone else and I wanted to wipe it clean.
Also should I use "erase" or "erase free space" if I want to wipe the drive clean?
Please help!

Sorry I don't really understand.... there are no partitions on the drive. How do I repartition it?
And should I use "erasing free space" or "erase" for wiping clean my drive of everything? Erase seems to be faster last tiem I tried.
Thanks!

Disk Utility encryption vs. FileVault 2

I'm doing a clean install of Lion onto my iMac and I would like to have full disk encryption. I'm booting to a Lion DVD and have just zero wiped my hard drive as "Mac OS Extended (Journaled)". I see an option for format as "Mac OS Extended (Journaled, Encrypted)" and was wondering if there are any differences or advantages/disadvantages to encrypt the boot disk in Disk Utility rather than FileVault 2. During research of FileVault 2 I discovered a drawback; one must shut down the computer to take advantage of the encryption:
From Macworld:
http://www.macworld.com/article/162999/2011/10/complete_guide_to_filevault_2_in_ lion.html
"While your Mac is booted, anyone with physical access to the computer—someone who sits down in front of it, breaks in remotely (however unlikely that seems at the moment with a Mac), or runs away with your laptop—could access your data. So get used to shutting down your Mac when it's not in use, or when it's out of your control, rather than putting it to sleep."
Any info much appreciated!

Update: I called Western Digital and they say this error is caused when one of the sectors of the hard drive is damaged in some manner (they didn't elaborate, but I assume it's some sort of physical corruption). So, if you have the same error, chances are you'll need to replace the drive.

Problems with External Hard drive, will not mount and errors in disk utilit

i have a powerbook g4 aluminum. i have an external hard drive for it. a simple tech 100gig portable drive, almost brand new. i dont know what happened to it, but one day i was starting my computer up with it attached. it wounldnt fully start up, said "waiting for local disks" so i uplugged the external hard drive. now it wont mount and will only show up in the disk utility of my friends macbook. i tried to verify and repair, and this is the message i got.
Verify and Repair disk “UNTITLED”
** /dev/disk1s1
could not read boot block (Input/output error)
Error: The underlying task reported failure on exit
1 non HFS volume checked
1 volume could not be repaired because of an error
Im in mexico writing a book and so i really need help on this one guys.

Hi, hjbugs, and welcome to Apple Discussions. Disconnecting the drive while your Powerbook was accessing it probably caused your problem. It may be repairable using DiskWarrior or TechTool Pro, but if you don't have access to one of those and aren't going to buy one, reformatting the drive with Disk Utility may be the only other way to make it usable again. If it contains data you need to recover first (i.e., data that isn't also stored on your internal HD or other storage media), download the free demo version of one of the data recovery utilities mentioned in this thread and use it to see what is recoverable. If the files you need are recoverable, buy the full version of one of the utilities and recover them.

Unable to create "filename.dmg" (error -60008) {Disk Utility Problem}

Hi:
I’ve used Disk Utilities awesome capabilities many times, but am now running into my first real problem.
I am trying to create a 100 GB new blank disk image, using the “Mac OS Extended (Journaled) option for format, 256-bit AES encryption, a single partition-Apple Partition Map, and Image Format as read/write disk image.
When I implement this, it asks for the AES password then repeatedly crashes, albeit in slightly different ways each time. The most informative was a Unable to create “filename.dmg” (error -60008) message. I can’t find anything explanatory about this in Google
I’m wondering if this has something to do with my upgrade to Lion (OS 10.7.4) yesterday from Snow Leopard.
This error occurs on both my home and work iMacs. It seems to reliably occur about 1/2 way through typing in my password. The error occurs whether I use 128 or 256 AES encryption.
There is more than adequate space on the hard drive I am attempting to place this image on. Disk Utility is version 12.1.1 (353) and all is running on a 2.66 GHz Intel Core i5 iMac.
Any advice would be greatly appreciated! Thank you
PS: This is a duplicate post from the OS Lion forums ( https://discussions.apple.com/message/18410534#18410534 ), but since a) it occurs on both my Intel iMacs, b) I totally rely on Disk Utility's capabilities, so this loss with the Lion upgrade really hurts, and c) we've had no luck in the Lion forums, we're hoping someone here has seen this issue and can help. Much appreciated.

Hello, I believe that's an authentication error, thinks your not an admin account. Might try this...
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, move this folder to the Desktop for now...
/Users/YourUserName/Library/Preferences/ByHost /
reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Disk read error, and Disk Utility won't open

Have a PowerMac G4 dual 800mhz, with two hard drives. Mac OS X 10.3.9 is installed on HD1. I use HD2 for miscellaneous files.
Using the Azureus bittorrent client, I'm getting "Error: Disk read error - Input/output error, read fails" in the Status column when trying to download something to HD2.
However, I'm able to upload files from HD2 for other users, and I'm also able to play video files that are stored on HD2 without problem.
The real issue is that when I went to see if I could fix anything by opening Disk Utility, it won't open. It goes into an immediate state of Not Responding. It won't listen to me when I tell it to Force Quit... I have to wait a long time, or restart the computer, to get it to stop showing up in the dock.
Any advice would be appreciated.

To repair a startup volume you must do the following:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
