Let me amend this to say “Won’t read ANY” DVD’s.
Had this Optiarc AD-7170A since 2006, burned 1,000’s of DVD with it. All my DVD’s are TY’s.
This 7170A has the original firmware on it. Never been flashed.
Any DVD I put into it to read goes from DVD-RAM to “CD-ROM”
Just burned 4 DVD’s yesterday, had no issues ejected the DVD’s and filed them. Today, 7170A drive also gives me the “CD-ROM” nonsense these 4 DVD’s also. The dvd’s contain MP3’s on them.
4 other PC’s dvd drives in the house can read all 4 DVD’s with no problems. It is as the 7170A is not sensing the DVD as a DVD and thinks it is a CD-ROM. I can pull 2 or 3 yr old DVD’s that all PC’s can read but the 7170A.
Can Anti virus do this? Been running NOD32 V4 for months with no issues.
