no mountable file systems ???

[DanL]

So I have a disk image that is password protected. I use that image to store passwords. I enter the password, and it opens it as a disk image, with files containing my passwords in it. Works great. Until now.

But I've run in to a problem while I happen to be traveling. I open that disk image, it asks for the password, I give it that password, and it comes back with

The following disk images couldn't be opened.
diskname no mountable file systems

Whaaat? I tried rebooting. Same problem. What gives??? I can't open that disk image anymore.

What doe "Get Info" tell you about that disk image? I have never used disk images, so don't know if this makes sense, vut what does Disk Utility tell you about it?

Can you try rebooting your Mac if you haven't already tried that, then trying to mount the .dmg file again?

Below is a link to a tutorial which may help:

Mount a DMG from the Command Line in Mac OS X

I did reboot my Mac. No joy.

Using the terminal command to attach the dmg file - "hdiutil attach mydisk.dmg", and inserting my password when asked, I get

"hdiutil: attach failed - no mountable file systems"

Same thing.

This always always worked!! Was the file somehow damaged?

OK, problem solved. I reloaded the dmg file, and everything works. Must have been a damaged file.
