Crazy Taxi - Driving me Crazy!!! - Plz Help

[kev1n~]

Hi, I'm having a nightmare backing up Crazy Taxi (UK PAL)
I am new to the PS2 scene, but have never had a problem using Clone cd for ANY psx title.
PS2 just keeps spinning the disk like a moped is revving up!!!
I have duplicated other existing backup PS2 disks, with no probs.
??Have I picked a bad game to start on??

Please Help- for my sanity!
PS2 - SCPH 30003 (UK PAL)
S-Box Modchip (USB)
NEC-NR7700A (Burner)
Clone CD / CDR Win / BlindWrite etc.etc (none help with C.Taxi)
Many Thanks....
Merry Xmas!!
