"No Mountable File Systems"

This appears to be a pretty known error. The only problem is, no solution seems to fix it. Lately I have been trying to download a few trials for software such as Little Snitch and Ableton(they both are amazing products from what I have heard). The only issue is for both of them the Disk Mounter gives me an error "No Mountable File Systems". This just started recently so I really have no idea what is going on. I tried opening them with Disk Utility as well and I get the same error. I also tried terminal commands and got the same error. There really seems to be no winning on this one. I really need to fix this ASAP.



Thanks.

I finally tracked down my "no mountable file systems" errors to com.lexar.driver.LexarFilterScheme - this is installed as part of a Lexar Jump Drive's secure II vault driver that my work requires me to use. Doesn't seem to be a newer version on Lexar's site.


As soon as I deleted /System/Library/Extensions/LexarFilterScheme.kext and rebooted, the error went away. Took me quite a while to isolate it to that piece of crap. 🙂

Hello Matthew,


You just saved my day! I too have a Lexar secure Jump Drive and got this error message of no mountable file system when trying to install software from Garmin. And not only that, my Garmin GPS would not mount on my Mac. After a short Google search I found your thread and when I removed the /System/Library/Extensions/LexarFilterScheme.kext everything went back to normal.


THANK YOU!


Best regards from Iceland.

Sorry, but I am a youngster for Mac (used other software since 1966 Olivetti 101, IBM1673, Fortran,GWBasic),

please explain how to find and how to delete /System/Library/Extensions/LexarFilterScheme.kext ,

I suppose that must be done with Unix commands, with which I am not familiar at all.

Lexar is probably my problem, I installed a memory stick on Saturday the 18th. Most programmes seem to work but not Open Office, deleted it but can't reinstall it, due to 'no mountable file systems' error.


Is there a manual for introduction in Unix language which you can recommend ?

May 21, 2013 6:04 AM in response to diablo9333

Yes, this helped me. It did not resolve my problem. I deleted the original file too fast, before checking if it did exist. However, it is, after deleting, not in Trash.


With the 'Go To folder' I was able to detect all system library files which have been installed or modified after the first of January 2013. Those seem to be for the major part Mac files and only one third party file set: xcaliber-0.9.28.dmg. I have made sreen shots from all the 2013 files.


My next step will be to do a the check with the Unix commands recommended by another good helper.


Thanks, and thanks and more thanks.

Thanks. It is the stupid LexarFilterScheme.kext in Mountain Lion also. I couldn't load Switch as I got the "no mountable file system" message.


Strangely, other .dmgs work fine. Anyhow, I ditched the Lexar kext and the message is gone.

What the heck is that kext for anyhow? Why does a printer company mess with .dmgs? Obviously they have no clue.

I had the same problem but did not have the LexarFilterscheme.kext file. However, I am including a link to Adobe forums where people posted the same problem. A staff member said it looked like that person had a damaged .dmg file. I was getting the same error message, also on a macbook pro. I downloaded the debugger flash player and that worked for me.

I totally removed the program Secure made by Lexar with CleanApp but it did not catch the faulty item and I had to delete manually. I cannot thank enough the person who found that crap and also the guys who are behind Default Folder who refered me here. I wrote to them about a problem with the Default Folder image and they helped me even if it was not their fault.

Hi there, I'm having a similar problem related to an encrypted file volume and I'm wondering if someone here could help. I'm trying to restore a TrueCrypt volume (a 10GB container I created) from a TimeMachine backup. The most recent versions of this file does not mount - I get the above mentioned "hdiutil: attach failed - no mountable files systems" . Strangely, When I go to my OLDEST time machine back ups - from about 8 months ago, and choose the file there, it mounts fine. SO, something happened to the file along the way as it was being backed up and I can't mount the latest version of it. Does anyone have any suggestions for getting this to work? I have tried mounting it on my 10.8.4 and my 10.6.8 systems, and get the same error. I have made sure I have the latest version of MacFuse installed. I tried mounting in SafeMode and it doesn't work either.

One clue is that when I clicking the "read only" option in TrueCrypt, and checking the box for "do not mount" , it seems to load the file in True Crypt as a "hidden" file type, but of course I can't see the contents of the container anywhere because the volume is not mounted. Can anyone help here? Thanks so much - apologies in advance if I missed something obvious!

Sorry to dig this one up again, but I am having problems with both Dropbox (installed after taking contents out of the DMG on another Mac as well as Rosetta Stone ISOs (I hate CDs but have tried burning them too). Mine is an MLPostFactor Macbook (Late 2007) running Mountain Lion (I think that this is what the OSX Hackers entry is below. Have tried their forums but to no avail, and do not have any Lexar stuff on here either.


So here's my output (looks like sparse responses to some of the commands), let me know what you see that I can ditch to fix:


roberthendricks$ kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'

I had a similar issue with Xcode command line tools dmg. When I mounted it using DiskUtility as stated below, there was a package file (.pkg) inside it. I have dragged the .pkg file to my desktop and double clicked it, this has installed the software.


To install dmg, you could try mounting the Disk image (dmg file) manually using Disk utility.

Open 'Disk Utility' app. Click File -> Open Disk Image . Select the dmg file. This should allow you to mount/open the dmg file and install its contents.

Note: You might have to copy the file content from the disk utility finder/viewer window to some other location, as I have done with the .pkg file found inside the .dmg
