Q:

PowerMac G4 - OSX 10.4.11

I cannot modify a CDRW  even though I am the administrator . Get Info shows my name as owner the read write is dimmed, the access is dimmed, the Ignore Ownership is checked but I still have no  control over the the disk.It tells me it cannot be modified. What gives

A:

Internal CD drive? - look in System Profiler and check the Disc Burning - the drive may not be a CD-RW drive. Can't modify A CD-RW? Or ANY CD-RW? Have you ever been able to do this? If you have, what brand was able to be modified? Using the same brand now? Was the CD-RW created on your computer? Was it created on a Mac? If created on a PC, there can be problems with modification, or it can be locked. I would test with a New Blank CD-RW and test. Highlight the CD-RW and get info. Uncheck Ignore Ownership, close Get Info, open it again, and see if the options have changed. You can look up your computer's specs at   http://everymac.com

Start up in Safe Mode (shift key down)  check the status -  there may be non apple software interfering. Open Disk Utility (utilities folder) and see what it says about the CD

Doing monthly maintenance is a good idea. I use AppleJack most frequently   http://www.macworld.com/article/135377/2008/09/applejack15.html
