can anyone tell me if my liteon 52x drive is defected? below URL take you to the page that show the nero scandisc and cd quality check result of my drive. the disc that i'm using is TDK 40x (ritek), Mitsubishi 48x, SmartBuy 40x (Prodisc) and unbranded CMC. all showed the same result. can anyone tell me what happen to the drive. it works find for the first few disc without any unreadable errors when test with nero scandisc . it also shows c2 error at the end of the disc when testing with liteon WSES 1.07 (don't know how to capture screen in DOS mode). i brought the drive back to the shop and they said it is technical error. the shop promised to check with liteon but after 2 weeks i didn't get any answer. please help! thanks

this phenomenon is very well known and was discussed here in these forums plenty.
if you burn in TAO mode the last "block" in ScanDisc will be read.
(for a detailed explanation search for threads in which this has been discussed).
the pictures you posted are of an excellent burn!

try burning again, this time in DAO mode. if all goes well (and it probably will) there will be no read "block" at the end.

With WSES, you suppose to read the user guide first.
Then run st.exe,
then wses.exe.
But you would know that if you did the first thing first.
