hi guys, i'm new here and this is my 1st post! i seem to be encountering a problem with reading of discs. hope someone can help me out here.. i've got a ASUS CRW-1610A and a Sony DVD RW DRU-720A. The DVD RW drive is connected as "Master" while the CD RW drive is connected as "Slave". Both are sharing the same IDE cable with the DVD RW drive connected to the top connector and the CDRW drive connected to the middle connector. - Went to Device Manager and both drives are working well. - Went to My Computer and both drives are labeled correctly when there no discs inserted (ie DVD-RW drive and CD-RW drive). Here's the problem.. No matter what discs i insert into both drives (VCD, original DVD, normal software installation CDs etc), when i double click the drive icon, the contents are completely empty and i right click for "properties", used space=0bytes and free space=0bytes also. However, i tried inserting a music CD into my DVD-RW drive ('coz that's the one that i connected the audio cable to), same problem happened (as in, windows explorer does not display the contents of the CD) but when i launch Windows Media Player direct and click the "open" function, it can detect that there's a music CD in there and i can play the tracks. I tried using the same method for VCDs, that means i opened my Creative Media Source Player/Winamp player first then tried to use the "open" function but contents of the drive were always empty (although "all files" option was already selected). Then, I tried to burn some data files (mixture of .exe, pictures, mp3s, avi files) to a Sony DVD-R disc and tested ok. Tried using my DVD-RW drive to read the disc that i had burned but same problem occurred (no contents). Testing reading the contents of the disc on my sister's fujitsu laptop and it was ok. Now, i'm even trying to go to DOS mode to try to access to my DVD-RW or CD-RW drive but i get the error reply "incorrect function". Ppl i've consulted narrow it down to either OS or motherboard problem and i was advised to reinstall my OS (WinXP Professional w SP2). But i'm not sure if it'll work as my 2 drives can't seem to read any CDs. Am really puzzled by this problem and really hope someone can help or provide some guidance. Sorry for the lengthy description coz I wanted to get all the information down. Many thanks in advance!
