"No Mountable File Systems"

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. 🙂

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:

• Be sure your Mac is shut down.
• Press the power button.
• Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
• Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem(s)?

After testing, reboot as usual (i.e., not in safe mode.)

I was unable to mount dmg files as well ("no mountable file system error").

After a long search and try and error (I was close to install OS X new from scratch) the solution was quite simple:

1. Run /Applications/Utilities/Disk Utility.
2. Click on "Macintosh HD" in the left column and then press the "Repair Disk Permissions button (so I did not repair the dmg file, I repaired the permission of my running OS X instead).

The miracle happens!

Mounting was running smoothly.

I hope this helps others!

Have you tried repairing the hard drive?

Repair the Hard Drive - Lion

Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. 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, then quit DU and return to the main menu. Select Restart from the Apple menu.

Boot to the Recovery HD:

Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

Also, have you tried downloading to a different hard drive destination such as an external drive or USB flash drive?

Do you have high speed internet or using a telephone modem?

Please read this whole message before doing anything.

This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software – potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions – they’re easy to carry out and won’t change anything on your Mac.

These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.

Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.

Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.

Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” (without the quotes) and press return. You should then get a new line ending in a dollar sign.

Step 1

Copy or drag – do not type – the line below into the Terminal window, then press return:

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

Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)

Step 2

Repeat with this line:

sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'

This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.

Step 3

launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'

Step 4

ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null

Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.

Step 5

osascript -e 'tell application "System Events" to get name of every login item'

Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer – no typing, except your password. Also remember to post the output.

You can then quit Terminal.

I have the same exact problem, but dont have Akami Download Manager installed, so it must be someother application. I can mount certain dmg only in safe mode.

here is the output from my system.

Well I'll just be doggoned. The problem started suddenly for me - nothing fixed it. Pretty much every post on the subject referred to user error, and how we were all doing it wrong. Finally I read Matthew's post about the Lexar software, which I had installed along with a Lexar thumb drive some time ago. Solved my problem immediately.

THANK YOU!! I have no idea how you found that, though I'm glad you did.

The recent updates i would say the last 2-3 minor updates seem to have made lion unstable alot of my programs that used to work no longer work after the updates and it also caused my account to get corrupted.

Thank you for posting your finding as it solved my "no mountable file systems" errors also. I used your resolution as I too had a Lexar thumb drive. Like you discovered as soon as I deleted the .kext file I was able to mount and load a couple of Garmin GPS updates and new maps. I had contacted Garmin via emails and their suggestions was to download the files again as they might be corrupted and /or contact Apple, which I didn't do as I wasn't looking forward to that potential circular problem.....Garmin says it's Apple, Apple says it Garmin 🙂

Thank you, thank you, I never would have found that. I don't use the Lexar Secure II any longer as it wasn't working well with Lion.....so much for encrypted thumb drives.

Please help! Nothing I download will mount on my system... and when I try to boot in safe mode the computer just shuts down again. I followed your directions and here is what I got:

abigail-fascianos-computer:~ Abi$ osascript -e 'tell application "System Events" to get name of every login item'

Okay. I have a small, encrypted disk image I created with Disk Utility that worked just fine until today. I had it saved on an SD chip and wanted to modify the files. I unlocked the chip and it refused to mount properly. The file was no longer visible, but when I locked it again, the file was there but I got the "No Mountable File System" error. I see the size is unchanged, but it refuses to open. Other disk images mount fine, and I don't have the Lexar file to remove.

Disk Utility can't do anything to the file, and I downloaded Stellar Phoenix Mac Data Recovery to try to fix it, but when I launch it, it asks for my admin password because it wants to change things. I declined the offer, but would like to know if it's possible to recover my files. I am currently running 10.8.3.

Thanks.

Still don't know what is causing the error!!!
