DMG mount - device not configured

Hi All:

For last two days I can not mount DMG images. I get a warning message when i try to mount = device not configured.

any suggestion??

I done following and also perm repair

Deleting the following:
/System/Library/Extensions.kextcache (file)
* /System/Library/Extensions.mkext (file)
* /System/Library/Caches/com.apple.kernelcaches (folder)
rebooting afterwards did not help.


and after reboot, it works for moment but then get the same message.

Any permanent solution to this problem?

SC

You should try the standard troubleshooting suggestions:
http://www.apple.com/support/mac101/ (see the "My Mac needs help" section)
http://www.macosxhints.com/article.p...04011205473937
http://forums.osxfaq.com/viewtopic.php?t=7269
http://www.thexlab.com/faqs/faqs.html

In particular, be sure to try logging in as a different user to see if the problem exists there. (Create a new user via the Accounts preference panel if you only have the one user account so far.)

Also be sure to do both permission repair and filesystem repair.
http://docs.info.apple.com/article.html?artnum=25751
http://docs.info.apple.com/article.html?artnum=106214

And if you need more help, please be sure to tell us what model of Mac you have and what version of OS X you are running.

And which DMG images do you have the problem with?
All DMG images?
Ones recently downloaded? From where?

I have run into a similar problem (same error message) occasionally since 10.4.9, and tried deleting the files you mentioned, rebooting, etc., apparently without result. However, since I have admin privileges on this machine, manually loading the com.apple.AppleDiskImageController kext when that error appears usually allows me to mount disk images, after which the problem seems to go away for a while:
Code:
sudo kextload /System/Library/Extensions/IOHDIXController.kext
I wish I knew what the root cause is, but the problem is intermittent enough (maybe once a month, if that) that I suspect hunting it down would take too much effort so I decided I can live with the workaround. Anyway, if your problem is the same and the workaround works for you, maybe it will at least save you a reboot...

Hi All:

I find that deleting files below solves the problem:

com.apple.frameworks.diskimages.uiagent.plist
com.apple.diskimages.fsck <- this may be the main culprit
com.apple.frameworks.diskimages.plist


may be problem with corrupt preferences.

Kind Regards,


SC

Hmm, that's very interesting.

On the one hand, on my system, those are user specific files but the inability to mount disk images was system wide, even on a fresh account. But if it is corrupted, I suppose it could be crashing the whole kext (I wonder if someone with the know-how might be able to exploit that somehow...)

On the other hand, the creation / last modification date of the *diskimages.fsck file on my system happens to correspond with the date of the 10.4.9 update receipt, and that's when I started having this problem, intermittent as it is. I think I'll keep the file around for now, and try deleting it the next time the problem pops up.

Thanks for the info.

Cool A bit lost

in regards to:

hi, i just got a Mac book pro a few month ago, so coming from PC, I am still getting used to this system.
I have encountered the same problem when trying to restore a disk image. Could anyone explain to me how you actually perform the action mentioned above, I found the IOHDIXController.kext, but how do I actually manually load it?

Copy and paste that line into Terminal, located in your Applications/Utilities folder. You will need to enter your Administrator password. Don't worry that it doesn't echo anything back. Just type it and press Return.
