TICKET ARCHIVE -> Disk Images Failing to Mount:Broken Pipe

lupus46 - Mar 21, 2007 - 10:07 am

Hi,

Ever since the recent 10.4.9 patch, I have been unable to install .dmg files onto my MacBook. Everytime I try to execute a .dmg file, I get the following error:

Disk Images failed to mount:

Program: Messenger602.dmg
Reason: Broken Pipe

I have absolutely no clue as to what it means. I've used the Disk Utility in order to repair the disks and permissions without any luck. I've restarted my computer a couple of times and that failed. I've also checked the forums on the subject and there were some topics on the subject but none of them were able to fix my problem.

I haven't tried re-installing OSX as I am unfamiliar with the process and am afraid of deleting important documents from my mac.

Any help would be greatly appreciated! Cheers.

Hi Alex

First I would try using

Onxy to clear all Cache files and run the Maintenance routines.
===============================================
If that doesn't help, reboot into Safe Mode. Restart holding the Shift key down. This will delete a couple files. Then restart normally.
===============================================
If that doesn't help, run 'FSCK';

To run fsck, you first need to start up your Mac in single-user mode. Here's how:

1. Restart your Mac.

2. Immediately press and hold the Command and "S" keys.

You'll see a bunch of text begin scrolling on your screen. In a few more seconds, you'll see the Unix command line prompt (#).

You're now in single-user mode.

Now that you're at the # prompt, here's how to run fsck:

1. Type: "fsck -y" (that's fsck-space-minus-y) (without the quotes)

2. Press Return.

The fsck utility will blast some text onto your screen. If there's damage to your disk, you'll see a message that says:

***** FILE SYSTEM WAS MODIFIED *****

If you see this message--and this is extremely important-- repeat running fsck. It is normal to have to run fsck more than once -- the first run's repairs often uncover additional problems..

When fsck finally reports that no problems were found, and the # prompt reappears:

3. Type: "reboot" to restart,

or type "exit" to start up without rebooting.

4. Press Return.

Your Mac should proceed to start up normally to the login window or the Finder.
=================================================
If this doesn't help, look in System/ Library/Plug-ins.
If there's a VPC helper in there, trash it and restart and try a DMG.
=================================================
If none of the above helps, download and run the

Mac OS X 10.4.9 Combo Update (Intel)

This won't remove or delete any of your files.

Hey,

I followed all the steps. When I ran the fsck -y i got these results

**/dev/rdisk0s2
**RootFileSystem
**Checking HFS Plus Volume

fsck_hfs: Volume is Journaled. No check performed
fsck_hfs: Use the -f option to force checking

I ran the -f option and everything was fine and the problem persists.

I wasn't able to install the 10.4.9 Combo update. When I tried to install it I got the Broken Pipe message again.

Any other possibilities?

Boot into Safe Mode by holding the Shift key while booting and try installing the Combo Update that way.

If that doesn't work, the next step would be to do an

Archive & Install
