To quote a few posts…
From the iHAS C thread:
[QUOTE=2601;2622873]The Drive ues Mediatek MT1809LN chipset and buffer length is 1.5M. All Liteon’s utilities work fine on the Drive except CK’s latest version FU cannot dump the correct data from the Drive.[/QUOTE]
and from the iHAS D thread:
[QUOTE=2601;2657934]The C and D series Drives use same chipset (Mediatek MT-1809LN) but have different PCB.[/QUOTE]
So you have to find a better way to identify the drive. You may have to dump the current firmware on the drive (assuming the original firmware is still on there and intact), then open it up or ask someone to look at it to get a true drive ID string.
Or maybe there will be a more definitive marking on the drive somewhere.
