I have install fhsprogs, and tried to mount a usb disk which is HFS+ but I can only get read access.
Any Help would be great
If it is a Placebo You can Believe in it !!!
From Wikipedia: "There has been some success in porting HFS+ to Linux, at least in non-journaled read/write. If the filesystem is journaled, it will default to mount in read-only mode, but it can be forced to ignore the journal temporarily (by using the 'force' option)."
So maybe you can mount it without journaling or use force option.
