Error Writing Entropy File

Hi all, I have been having probs with my iBook for a couple of weeks now where it just sits on the grey screen with the spinning gear. I cannont start in safe mode, hardware test reveals no errors, disk utility says that HD and permissions are fine, clearing the PRAM didnt help, I cannot do an archive and install as there is not enough room left on my HD. I can start in single user mode but cannot remove files as super user (su) or by using "chmod" to change the file permssions, "sudo" doesnt work either for "rm " or "rmdir ". Also, i cant login to my user account (login) because it says that user doesnt exist. I have also run "fsck -yf" and "mount -uw" and this doesnt help either.I just tried to boot into verbose mode and it stopped. here are the previous lines so that you may be able to tell me what is going on:Creating RAM Disk for syslogdhdik: IOKit timed out waiting for driver to load: error e0002d6.hdik: attach fail: error e0002f0syslogd: cannot create /var/run/syslog: Read-only file systemsyslogd: child pid 113 exited with return code 1Creating RAM Disk for Crashreporterhdik:IOKit timed out waiting for driver to load: error e0002d6.Launching Crash Reportercom.apple.SecurityServer: database /vardb/CodeEquivanceDatabase opened READONLY (R/W failed errno=30)com.apple.SecurityServer: error writing entropy file /var/db/SystemEntropyCachecom.apple.SecurtiyServer: Entering service Can anyone tell me what this means? I would like to avoid doing a format and install if possible and the bad thing is i dont know anyone else that owns a mac so that i can direct link them.Any advice or suggestions would be greatly appreciated.rosscoiBook G4 Mac OS X (10.3.9) iBook G4 Mac OS X (10.3.9) iBook G4 Mac OS X (10.3.9) Posted on Feb 26, 2006 2:25 PM I have this question too Close Q: what is this error message?

Prevent SystemEntropyCache writes to disable drive spin-up Jan 26, '04 08:30:00AM • Contributed by: iixhd Mac OS X 10.2.8 (6R73) runs on my iBook G3 800MHz. I use the "Put the hard disk to sleep when possible" setting in the Energy Saver preference pane. Something was making my hard drive spin up every 60 minutes. After some digging, I found that SecurityServer was writing to the file /private -> var -> db -> SystemEntropyCache. The following modification disables this write activity; do https://discussions.apple.com/thread/381210?start=0&tstart=0 this at your own risk. You are preventing writing to a file owned by "system". [robg adds: I concur - this hint is experimental and potentially dangerous. I haven't tested it, nor do I have any intention of doing so! However, if spurious disk activity really bothers you, read the rest of the hint for some advice on how http://hints.macworld.com/article.php?story=20040114142533291 to remove at least one source of activity...]To stop writing to this file:Go into the Finder and use the menu command "get info->ownership and permissions". Change the the owner to the current user and allow read and write access on the directory /private/var/db and the file /private/var/db/SystemEntropyCache. Note the original settings before making changes. 2: Go into the terminal and type: cd /private/var/db rm SystemEntropyCache ln -s /dev/null SystemEntropyCache Change the permissions settings on the directory /private/var/db back to their original values. Also try to change the permissions settings on the new symbolic link called SystemEntropyCache back to their original values. In my case for that link, the get info dialog box would ignore attempts to change the owner. My computer was tested after making these changes. It takes about 10 minutes for the spinning hard drive to spin down. It did not spin up after 2 hours 10 minutes, at which point I manually spun up the drive by opening a file. This was much better than having the hard drive automatically spin
