	Blu-ray drives manufactured by [https://en.wikipedia.org/wiki/Hitachi-LG_Data_Storage HLDS] using the MediaTek MT1959 chipset have all the features required for good CD dumping, with some caveats. HLDS has both slim ~~external USB~~ drives ~~(based on the same platform as the LG BU40N drive)~~, as well as at least ~~four~~ "platforms" of their half-height desktop drives: '''JB9''', '''JB8''', '''JB7''', '''JBC5'''.

Half-height desktop drives based on the older '''JB7''' and '''JBC5''' (MT1939 chipset) are currently accepted for redump verification submissions if they are on the [[Optical Disc Drive Compatibility: CD\|compatible drives list]] and support the required firmware.

	Half-height desktop drives based on the newer '''JB8''' and '''JB9''' platform had the 0xF1 opcode removed in later firmware versions, so require specific earlier firmware versions to read the lead-out with the cache (typically the earliest available). However, all of these drives are able to be cross-flashed to [[OmniDrive]] that enables reading into the lead-out of a CD without the use of the cache. Drives flashed to OmniDrive are acceptable for both new disc dumps and verifications. See the [[OmniDrive]] page for a detailed listed of compatible '''JB8''' and '''JB9''' drives and flashing instructions (redump recommends using OmniDrive for all submissions with '''JB8''' or '''JB9''' drives, rather than their stock firmware).

			Finally, slim drives manufactured by HLDS using the MediaTek MT1959 chipset include the internal drive LG BU40N ('''BU5''' platform), LG BU50N ('''BU51''' platform), and BP71N ('''BUP5'''), all of which are also commonly used in third party slim external USB drives (Buffalo, Verbatim, etc). LG also produces their own set of external slim USB drives, BP50NB40/WP50NB40 (svc code NB40 is '''BUP1''', svc NB52 is '''BUP3''', svc NB52 is '''BP32'''), and BP60NB10 ('''BP52''').

			Of the slim drives only '''BUP1''' (BP50NB40 svc NB40) does not use the MT1959 chipset and so is not compatible with OmniDrive. There also exists an older LG BU20N internal slim drive which is incompatible as well.

	Blu-ray drives using the MediaTek MT1959 or MT1939 chipsets have been found to support the majority of the features required for dumping CDs compatible with redump.
