CD/DVD Drive Doesn't Working

I posted this a couple of months back: I have a Toshiba Satellite L300 and my DVD drive doesn't seem to be working. I tried it with various CDs and DVDs and it never detects anything. So I went to the Device Manager and this is what it says: TSSTcorp CDDVDW TS-L632H ATA cannot start (Code 10)." But while the solution kind of worked, it's still not playing the DVDs everytime. First, it doesn't always eject the disc. The only way I can ALWAYS get it out is during restart, or using a paperclip. Second, even if I take the disc out, the computer still tells me it's there (it displays the disc name too...). And worst of all, if the disc is in, it displays the disc name and I click on it, it doesn't load anything most of the time. Unless I restart it, take the disc out at that time and then put it in (and that's not guaranteed to work either).
