I am having a problem with Macbook when connected to external hard drive. Finder stops responding and I have to force quit. message it gives is error 10810. I could not move files to and from external hard drive. This is a big problem as my internal hard drive is full. I have bought a new hard drive and created an image of my internal hard drive on new one, so I can install a new one. I used restore function in disk utility to create an image. I tried "verify permissions" on new new hard drive (I haven't installed it yet), and it is giving me hundreds of lines of error. Mostly they starts with " ACL missing on "system/......" There are also few messages like "permissions differ from ......". One message is "Warning: SUID file System/library/coreservices/remotemanagement/ARDAgent.app/contents/MacOS/ARDAgents has been modified and will not be repaired". I have tried "permissions repair" and looks like it repaired all the "ACL missing on.." and some "Permissions differ from....". But "Warning:SUID file....." error was't fixed. I reran "verify permissions" now and and it still shows two "permissions differ from....." errors and one "warning:SUID...." error. permissions error is "permissions differ on system/library/frameworks/javaVM.frameworks/versions/1.6.0/resources/javaplugincocoa.bundle/content/resurces/javadeploy.jar" should be -rw-r--r--, they are lrw-r--r--. second persmissions error is similar with ending like "..........java/librarydeploy.jnilib", should be -rwxr-xr-x, they are lrwxr-xr-x. what these errors mean and any suggestions to correct them?
