Lost access to some folders on partition
I have a NAS (DNS-323) that's running Linux. I'm not sure what happened, but I'm suddenly unable to access some of the folders. I suspect permissions have gotten muddled up somehow, but I don't know how to fix. My Root login also no longer works, though I'm sure I'm using the correct password. I believe there are bootable Linux CDs that allow you to recover passwords, but as this is a NAS, I'm not sure how to proceed.
I've always struggled with Linux stuff, so am hoping somebody out there can offer some possible fixes?
