Need more info m8,
Like what's you system and you reader/re-writer make and what settings areyou using in clone?
Try these;- (when reading)
Tick read sub-channel data from tracks
Tick read sub-channel audio from tracks
Then tick do not repair sub-channel data
And tick finalize cd
Only read at a max of 8x and do not write any faster than 4x
Try going to
www.cnet.com and find the download section and search for clony xxl , download and install this (it's a detection program and will pass on the setting to clone) but it will not set read and write speed(this has to be done manully)
Sorry so long winded but hop this helps somewhat?
ps. Also if your reader cannot read sub-channel then you will not be able to back up psx anyway.(if it's a dvd then only Toshiba and lite-on work that i know of )
