Remove , eradicate stubborn strange character files on OSX

June 6, 2012 Leave a comment

This problem maybe just small problem but disturbing when you see a trash with files that you can’t remove.

I have been Facing this kind of problem for several month since try to create some modification on my own application.

When the modification done, i trashed all files related to this project , and using empty trash option to completely remove it. But, there are several files with strange name with special character can not be deleted.

I try several ways to remove those files, but no luck. Using command rm -f, trying to rename those files, and so on.

After several month passed, the light come up. Accidentally, when i reboot my mac, i hit the SHIFT button, and my OSX boot on safe mode. When i logged in, I try to empty the trash, and voilla … My trash now empty … hahahahaha

So, the conclusion, if u wanna eradicate stubborn files on the trash, try this step :

1. Boot on your mac os on safe mode (Hit the SHIFT Button while booting up)

2. Log in

3. Empty Your trash

4. Reboot normally ..

Creating ISO on Mac Os Leopard (CD Backup)

February 13, 2012 Leave a comment

Creating iso on mac os is easy to do. With simple step we can backup our CD/DVD into *.iso file and used as primary backup in case our original CD/DVD is scratched and can’t read anymore.

In this case, i’ll try to backup CD/DVD original application bundled shipped with Mac Book Pro.

There’s 2 way to make an iso,

1. Using Disk Utility

2. Using Terminal command

i prefer using 2nd method instead of 1st method, cause of lot of problem occured using disk utility.

The steps are :

1. Open Terminal

2. Insert CD/DVD into drive

3. Invoke command

drutil status

4. From step 3 we can see the drive , i.e /dev/disk2

5. Invoke the following command to start making ISO

 dd if=/dev/disk2 of=<filename>.iso

6. Wait till process finished

7. Mount the iso to verify the content using finder and DiskMounter
