I attached an hdd to my win7 machine and assigned the drive letter
I: to the only partition on the hdd. The hdd was originally from another computer, and to avoid all those "you don't currently have permission..." dialogs, I decided to use
icacls to clear all ACLs.
icacls I:\ /reset /t /c /l. After a while, Chrome stopped working. Safari crashed. I traced the problem and find that the ACLs of my home folder (in
C:\Users) are all messed up. Chrome and Safari couldn't write to their cache folder. I fixed the ACLs of my home folder and everything seems to be OK now.
icacls mess with my home folder when I specifically told it to work on the
I: drive? I have even put in the
/L switch so that it won't resolve symbolic links. Did I misunderstood the switch?
For your reference, below is the relevant parts of the help screen.
ICACLS name /reset [/T] [/C] [/L] [/Q] replaces ACLs with default inherited ACLs for all matching files. /T indicates that this operation is performed on all matching files/directories below the directories specified in the name. /C indicates that this operation will continue on all file errors. Error messages will still be displayed. /L indicates that this operation is performed on a symbolic link itself versus its target.
