I have one of those “generic” DVD burner with a Toshiba chip in there. I believe the model number is SD-R5272. The drive was only able to burn 4X DVD medium so I installed a Samsung firmware SH-W08A to enable it to burn 8X medium as per instruction elsewhere on this web site. It’s been working well without incident, until this past 3 days. The DVDs burned no longer works properly, and the DVD drive can’t quite read other DVDs. Some of the data burned would fail verification afterwards. But some of the video DVDs would still work ok with it. I ran Nero’s drive speed and some “unrecoverable read error” came up. I vaguely remembered there may have been a power surge this past week, but I have a surge protector on the electrical outlet.
To make a long story short, I am trying to find a tool to determine if the drive is indeed damaged behind any means to repair, before I rush out to buy another one. I already checked the software section under “diagnostic/utility”, but found no suitable software for this. Any suggestion?
