An update on drives used to read the failing DVD. The order of the drives have been revised after a bit more “testing” in trying to read the failing DVD.
Ordered from best reading drive first, with the worst performing drive last. Note that drives are listed in approximate order, especially for drives within the middle of the list.
LiteOn iHAS324 C, firmware LL14, chipset Mediatek MT1809LN
LiteOn iHAS124 F, firmware CL99, chipset Mediatek MT1862N
LiteOn iHAS324 B, firmware AL14, chipset Mediatek MT1839LN
Samsung SH-224GB, firmware SB00, chipset Mediatek MT1862AN
LG GGW-H20L, firmware YL05, chipset Renesas R8J32702SFPV
Asus DVD-E818A9T b, firmware 3.00, chipset ???
Plextor PX-891SAF, firmware ???, chipset Mediatek MT1862N
Toshiba SD-H802A, firmware HP10, chipset Toshiba TC94A68FG
Optiarc AD-7200A, firmware 1.09, chipset NEC MC-10043
Pioneer DVR-215, firmware 1.22, chipset NEC MC-10042
LG GH24NSD1, firmware LG00, chipset Mediatek MT1862AN <- unreliable in copying failing data
Currently down to 75,620 missing sectors. Was using the SH-224GB drive, now using the GGW-H20L drive. Will switch back to the iHAS324 C drive shortly as the GGW-H20L drive is struggling a bit to read remaining missing data.
