Can not access internal hard drive from computer

I have tried to restore from telnet like reconmended from this user [cyberstudio]
[Nov '17]
Telnet to your N900 Central by following these [instructions ]
cd /etc/scripts
./ partition_hd

WARNING: this will wipe out everything on the internal HDD, of course.

But when I open the drive from my mac it can not find the original item for public or admin if i click that.

It also does not show up under windows 7.

I would also like to get the latest firmware as mine is 1.05.12 from sept 2012
