|OK I know they are cheap and easy to replace but for the sake of my sanity, I need to understand this!|
My Dell XPS720 shipped with a DVD reader (Toshiba TS-H353B) and DVD writer (Sony Optiarc AD-5170S). I've not hammered them, utilised DVD Fab and Clone DVD for making backups of around 30 purchased discs and Imgburn for producing maybe 50 discs from torrent files. Never had a problem burning at up to 16x, in fact coasters were non-existent. I use compressed air sensitively every six months or so to clean the drives.
Until recently I've always bought DVD+R (or RW) blank discs as that is the format used by the PVR connected to my television. However last week I bought a large spindle pack of Sony DVD-R discs on offer at an irresistible price in my local supermarket.
And now... any DVDs created from ISOs or built from VIDEO_TS folders aren't recognised by either drive, even the one that burnt them. Windows Explorer eventually crashes, the analytical program CDRoller does too. But if I pop the discs into my girlfriends laptop or her PVR, they play perfectly. I can still use both drives simultaneously to copy discs via DVDFab or CloneDVD though again, neither recognises the end product.
Blank discs and ones created in the DVD+R format are instantly recognised by my machine, can watch films without glitches. Further strange thing, if I use Imgburn, or BurnAware Professional to create a data disc/DVD containing an x264 video file the process seems to complete efficiently but the disc is then deemed to be corrupt in my machine, girlfriends laptop or work PC.
Any ideas on what is causing this? Don't think it's a virus, I installed Kaspersky immediately after buying the PC and do regular sweeps using Adaware too. When I run "diskmgmt.msc" with any DVD-R media present, the file system of both drives is stated to be RAW, if that is relevant...
Thanks in advance!
Forgive me if I occasionally ask silly questions. I'm only human!
