I have several .dmg files. However, they will not mount. I get an error that the file cannot be verified. How can I fix this?

Matthis,
My name is Cheryl and I will be assisting you.
First, try repairing permissions. Go to Applications>Utilities and start up Disk Utility.
Since these files are not mounted, you need to repair the permissions on the entire hard drive. Click on the second hard drive icon in the side bar at the left,
Then in the first aid tab, click on Repair Permissions (repair drive will be grayed out).
Once done, give those files a try.

Thanks for the advice, but I repaired the permissions and I am still stuck with the same problem. Also, another file says error 95 "no mountable file systems". That file is in 3 parts (from 3 separate disks I believe). It does not have the extension .dmgpart though. All these have worked in the past...

Matthis,
It could very well be a damaged file. Give this a try and let me know if it corrects the problem.
1. Shut down the computer if it is on.
2. Press the power button to start the computer.
3. Immediately press and hold the Command (Apple) key and the "s" key for single-user mode.
4. At the command-line prompt, type: /sbin/fsck -fy
5. Press Return.
The fsck utility will go through five "phases" then return information about the disk's utilization and fragmentation. Once the check is finished, if no issue is found, you should see "** The volume (name of volume) appears to be OK."
Note: If fsck alters, repairs, or fixes anything, it will display the message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command until it no longer appears. It's OK if you need to do several "passes" of fsck, because first-pass repairs may uncover additional issues.
When fsck reports that, "** The volume (name of volume) appears to be OK.",
6. type: reboot
7. Press Return.

I tried it many times, but it keeps modifying the same files. Do I need a better repair program like norton?
I have an additional question. I am looking to upgrade the ram on my mac. I have a firewire clamshell ibook (indigo). I have found coflicting info on how high I can go (256 or 512mb). Can you help me with this too?

Matthis,
If fsck can not fix the problem, it is indeed time for a third party utility. I recommend Disk Warrior or TechTool Pro. Do not use Norton Utilities on a drive with OS X on it. You may have more trouble than what you started with.
Tech Tool Pro - http://www.micromat.com/tt_pro_4/tt_pro_4.html
Disk Warrior - http://www.alsoft.com/DiskWarrior/index.html
You can buy it on line or at a store that sells Apple computers and software.
The iBook - Apple says 320 MB, but in actuality you can go to the max of 576MB. There is 64 MB already on the logic board, so you can put in a 512 MB and be okay.
