I just purchased a TS-L632D CD/DVD/BD drive and, like others, can not use the drive to read blue-ray discs. I downloaded the driver from Dell and applied it - nothing. I found a post here about downloading the SC04 version and using that - nothing. I went off across the internet to Korea and downloaded software from TSST itself to try - nothing. So I was a bit frustrated to say the least. Still am frustrated actually. However, I came across a resource that was too good not to post something here about. It is a repository of ALL of the various drivers for the TS-L632D CD/DVD/BD drive. The repository is located here:
http://backfire.rpc1.org/tsstcorp/index.php?path=TS-L632D/
In this one location are somewhere around 40 different versions of the driver software - even Dell's driver. Here you can download each one and try installing it to see if it works for you. Enjoy! :-)
This is my good deed for the day. :-)
