Access Denied Error
I am an inexperienced Linux user who has Linux installed on my laptop. I am running Red Hat Linux. Until yesterday I was successfully able to read and write files to my hard drive as well as to my zip drive. However, I was only able to write to my ZIP drive from root. So, as an inexperienced but brave newbie I tried to fix it myself. I went to root, typed in 'chmod 777 /dev/sda4', deleted /mnt/zip250.0 and re-created it, and thought this would fix the problem.
Now, I cannot write to ANYTHING. No matter if I'm logged in as root or as myself, and no matter if I am trying to write to my zip drive or my hard drive, I cannot write files anywhere. I get the message "Access denied. Could not write to [directory]", where [directory] is whatever directory I'm trying to access.
I checked the permissions using 'ls -l' and the permissions on the directory are read+write, so I don't understand why I'm getting this. Can someone help? I'm going to lose my data!
Thanks to anyone who can help. Your assistance is greatly appreciated.
