I’ve got an Optiarc 7260s, flashed with Liggy’s 1.03bt firmware.
In XP, discs read fine and I scanned one and it was fairly good at 94%.
In Win7, the same disc causes Explorer to freeze and the drive head can be heard constantly struggling to read the disc. The contents are visible but clicking on a folder doesn’t open it, or at least not for ages, so something about Win7 is making the drive act wierd.
I’ve gathered some driver info from both XP and Win7 and attached it below. I have tried disabling Daemon Tools’ SPTD driver and also uninstalling and reinstalling the 7260, neither of which has helped.
There’s also a load of Event ID: 51 warnings in the log which say “An error was detected on device \Device\CdRom0 during a paging operation.”
