"Do not enter" sign after iDefag finished

My wife's MacBook Pro (17") running 10.6.8 was sluggish so I ran iDefrag 2.1.1 successfully. It was still sluggish so I ran it again. (Both times restarting using the prompt in iDefrag.) The second time it successfully finished the defrag but when I restarted the MBP the Apple appeared at initial startup, the grey wheel spun for a bit and then another grey screen appeared with a grey "do not enter" symbol and the grey wheel spinning eternally. (The "do not enter" sign/symbol is a circle with the slash through it.)
I have booted her MBP as a target disk connected to my MBP (also a 17" running 10.6.8). I can see and access everything on her hard drive no problem. I tried rebooting my MBP using her MBP and I get the same "do not enter" sign.
So I ran Disk Utility from my MBP and it said "the volume appears to be OK."
So I bought and ran DiskWarrior 4.4 (I had DW 4.0 but it wouldn't run on 10.6.8). It says that the "drive is functioning normally".
I then used DW 4.4 to "Repair Disk Permissions" and "Check All Files & Folders" and it reported:
Open error 18446744073709551594: "unknown error: -22" on usr/libexec/postfix/error
Open error 18446744073709551594: "unknown error: -22" on usr/libexec/postfix/qmqpd
Open error 18446744073709551594: "unknown error: -22" on usr/libexec/postfix/trivial-rewrite
Open error 18446744073709551594: "unknown error: -22" on usr/libexec/postfix/virtual
...then a bunch of others with the same Open error number.
Then it said that a bunch of .plist (Epson, HP and others) cannot be repaired.
Then I rebuilt the directory and it said: "All file and folder data was easily located." "Comparison of the original and replacement directories indicates that there will be no changes to the number or contents of files and folders."
Still the same problem at startup... "do not enter".
So I restarted holding command-v to see what it had to say and it reported numberous things, such as:
Can't load kext com.apple.driver.ApplefileSystmeDriver - failed to resolve library dependencies.
kext com.apple.driver.AppleFileSystmeDriver failed to load
Kext com.apple.iokit.IOAHCIBlockStorage - library kext com.apple.IOKIT.IOStorageFamily not found.
kext com.apple.driver.AppleFileSystemDriver failed to load (error 0xdc00800e)
The other kext that failed to load with the same error are:
com.apple.iokit.IOSCSIMultimediaCommandsDevice
com.apple.iokit.SCSITaskUserClient
Then I get:
Couldn't alloc class "IOSCSIPeripheralDeviceType05"
Couldn't alloc class SCSITaskUserClientIniter"
The OS install disks that came with this MBP are 10.6.3 and when I tried to do a re-install it said that it couldn't install on this Mac. So I thought that I'd install Lion and see if that fixes things but I can't find it on the store (maybe because Mountain Lion comes out next month?)
Any suggestions?

OS X doesn't need repair
Please tell me you don't seriously mean this. There is no file system in existence that will not have at least the occasional problem.
Right, and Disk Utility is there for that purpose.
Outside of corrupted caches that the free OnyX takes care of, one doesn't need anything more really.
File systems and the files themselves can be damaged in a myriad of ways without having physical sector or other hardware related problems.
And Disk Utility is there for that too.

Sorry, just don't see that, that's what backups are for.
There have been many cases in these forums alone where DiskWarrior was able to repair a drive's files or file system well enough for a user to at least back up their personal files when Disk Utility either declared the disk okay, or couldn't fix it.
I don't see it much used around here actually and if it was a seriously viable tool, I certainly would have incorporated it.
I've been using Mac's since day one, fixing them plenty and never had a need to use Disk Warrior, in fact I've had only one hard drive fail on me and it was due to mechanical reasons, it just died.
I don't know of any Apple geniuses that use it, nor any of the Mac computer repair techs that use it.
What I do see is desperate users eager to grasp at a software solution that buy it, like they buy iDefrag or other software promises to "speed up" a Mac, like MacKeeper.
IMO the large proportion of DW users have much bigger problems that they really should be replacing the troubled portion or zero erasing and reinstalling instead.
Sorry, I'm just not sold on DW.
Ask Linc Davis about his opinion on Disk Warrior, see what he says.

Do Not Enter Sign on Macbook Pro. 2010 13 inch

Hey Guys,
1.5 years into the life of my MBP and somethings gone wrong. Was getting the Mac out of sleep and it froze so I hard rebooted it, and it went to normal start up and then the Do Not Enter Sign came up and after googling it, tried everything. When i go into Disk Utility from the disc, it doesn't see the hard drive, only sees the disc itself. Weirdly, i dont know if anything's wrong with the hard drive since I have boot camp on the Mac, and I can log windows and even access the Macintosh partition and take files out. if anyone has any ideas, greatly suggested.
thanks.
JM.

It sounds like the prohibitory sign is indicating a kernel panic at start up:

No enter sign after PRAM and PMU reset

I have an ibook 900, 14 inch, which is having video problems,so I reset the PRAM and PMU and now it restarts to a blue screen with a '?' in a folder. I try to restart in target mode but my G5 will not "see" the ibook. I have tried the c and x start up procedures along with the O F command to get into openfirmware (which does let me enter "printevn, mac-boot"), but still after the chime at startup I now get the gray screen with the apple and spinning icon then the apple turns into a do not enter sign. Have I toasted the ibook? I have looked at many discussions, and followed many links, HELP!

Do you have the original install disks? You might need to run the Apple Hardware Test. It sounds like the hard drive is no longer available. This could be due to either a hardware or software problem. You could test the hard drive with the AHT or test the file directories with the Disk Utility on the Mac OS X installer to figure out what's going on.

Some how do not enter sign was added beside contact, now all messages previously received messages are gone and no new messages from this sender will appear.

I have been receiving messages from this sender fine and then all of a sudden for some reason there was a do not enter sign beside her name. I didn't know how or why it got there, some button got bumped or the mouse, and I didn't know how to take it off so I just left it. Since then, thunderbird has been reopened and all messages that I had received have disappeared and no new messages from this sender appear even though I know she has sent them to me. I have checked into filters and I have none set so it is not that. I can't figure out how the do not enter sign got beside the contact, but I'm sure it's the reason for my problems and I don't know how to fix it. Thanks

How to boot when I get the "do not enter" sign

I am working to help a colleague that gets a "Do Not Enter" sing on boot-up of an iMac that was purchased through the university that we work with. From reading other posts, it was suggested that we re-install the OS to overcome the issue; on the assumption it is created by a corrupt file. This has proven not to work and we still get the same "Prohibited" sign during the start-up process. When Disk Utility is run, the boot sectors appear to fine and do not require specific repairs. Disk permissions were also repaired, but neither process has helped or corrected the problem. I am curious if others have encountered this issue and whether there is an easy work around? I came across one potential cause/solution - a bad SATA cable - however, I am unclear how the recovery disk could boot and run if the IO cable was bad, or even if the HDD was failing and working only intermittently. Any help/solution would be much appreciated. Thanks.

I suspect you have eithter a corrupt or failed HD. Attempt to restart, when you hear the startup tone hold down the Option key, then choose the Recovery Partition and open Disk Utility. Try to repair the HD, if it comes up with errors after 2-3 passes then you know the disk needs to be replaced.

DO NOT ENTER sign on boot up

I was organizing some audio files when Finder froze up. I had no option but to reboot, but then when I rebooted an internal drive wouldn't appear... as though it's vanished. And now I can't even boot up because I get a DO NOT ENTER symbol on start up.
Help! What is happening? I've tried Disk Utility and Tech Tool Deluxe. Both say everything on the main System drive is fine.

A driver was not digitally signed after software and driver installation on Windows 7

error, deivice status not working properly for my H Officejet Pro 8500 a909a printer . In Device Manager I noticed a driver was not digitally signed which i beleive is causing my Internet Explorer to not work properly.
Is this a driver I need to correct or get signed? How do I correct this problem?

Thank you for the reply, and potential fixes. I have combed the MS site already. The workarounds may provide some return functionality, but this type issue between two companies as HP and MS seems peculiar, and I am holding out for a permanent bonafide solution.
For example, the "F8 override disabling all digital signatures" plus installing yet another program to continue with every reboot is just not a viable solution to me.

Circle Slash "Do Not Enter" on boot after iDefrag

I ran iDefrag last night because my MBP was running sooooo slow. I barely ever use it and it has 300 GB of free space. I used to use OnyX to optimise the disks on Snow Leopard but I didn't see that option in Lion. I let iDefrag run and went to sleep. This morning I woke up to the Do Not Enter sign and the spinning thing below it. I made sure I left it plugged in so I don't understand what happened.
How do I fix this and not lose my data?

Despite some software developers claims, Macs do not require defraging and therefore the cause of the system slow down will be found elsewhere. It sounds, unfortunately, that your HDD may have been ready to die and iDrag just put the final nail in it. Unless you can get it to mount by repairing it with something like DiskWarrior, then I would think, given that it sounds like you have no backup, that you may be in some trouble here. Do you have any form of backups?

G5 will not start-up after 10.4.4 update - HELP!

Well, I'm currently updating my Quad as I write this on my laptop. So, in a few minutes I'll kniow whether or not my upgrade will be like all of the positive comments in another thread or like this single one.
I suppose you will need to startup the problem child with your original DVD and see if you can repair the offending start drive.
Keep us posted.
I'm off to my computer room to check the Quads status. Later.

Why can I not disable the guest user in the 10.8.2 update? I have never enabled the guest user, but after the update, it was automatically enabled with a "managed" tag. It is not selectable even after entering my admin password to unlock the options.

Why can I not disable the guest user in the 10.8.2 update? I have never enabled the guest user, but after the update, it was automatically enabled with a "managed" tag. It is not selectable even after entering my admin password to unlock the options. I was able to select the account under "parental controls", but again, could not delete it. Why Apple? Why?!!????

SOLVED Ok. I actually was able to disable it. I had to actually log in as the guest user to make it accessible in the preference window. Then I disabled it and logged out. Apologies if this was obvious for some people, but I have had some sort of issue with something every update since Snow Leopard.

Adobe Reader X does not save signed copy after hitting "Done Signing"

Version 10.1.6
When I click "Done Signing" after adding my signature to a signed document, I get the warning about the added text being permanently merged, then the "Save As" dialog comes up, but the file is never saved, regardless of whether I renamed the file or not.
I naively spent over an hour filling out forms and "saving" the results, in the belief that the program was saving my filled out forms just because it said it was. I'll have to be more careful in the future.

When you "save as" as opposed to simply "save", there is sometimes a different location for the file to be saved. When you "save as" to the same location as an original, you will bewarned that a file already exists with that name and be asked if you're sure you want ot overwrite the original file. If you didn't see that when "saving as", you probably saved the signed file to a different location.

Why the photo app is not closing after i finish, when i take a picture accessing directly from home screen. the location is draining my battery if I'm not closing the app by double click home button. in iOS 6 was not like this

Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.
