Subject: Re: Need help with mount and /etc/fstab
I don't think that's the right umask.

The filesystem appears to be mounted rw all right. The problem appears
to be that Contacts and Notes aren't readable or writable. Compare
security bits with Calendars. Why they're set that way (by the Ipod, I
presume) I don't know. If you "chmod u+r Contacts Notes", that should
turn the read bit for user on. "chmod u+rw Contacts Notes", that should
make them read-write.

I'd do so with caution. I don't know anything about Ipods, but I'd look
into its setup, and try and figure out why Calendars is rw, while
Contacts and Notes are not readable nor writable.

User and group 99 are defined by ipod, but are undefined on your linux
box, which is why they're listed simply as 99, as the system doesn't
have a name or group corresponding to that number. I don't think that's
a problem though, as the security bits for those directories are all on.
