I have a Dell Dimension E520 (DM061) with TSSTcorpDVD+-RW TS-H53A as told by my Sandra diagnostic program.
This machine has also (told by Sandra) an HL-DT-STDVD-ROM GDRH10N (Hitachi LG).
I cannot find either unit in any place of Internet.
Toshiba Samsung does not give information of first one.
Hitachi-LG does not give information of the second one.
Where can I find technical information, drivers, firmware, etc. of both units ?.
