I am noticing my 812s@832s drive cannot read some media properly, if I am observing right it is CDRW media it is having trouble with, inside windows it can read the media (after a long delay) but on bootup it cannot. So eg. I am about to try putting memtest86 on a dvdrw instead of cdrw to see if it works.
Is this problem likely to be a physical issue with the drive rather than firmware? I am curious if I flash back to 812s if it will work. I would be gobsmacked if its drive failure as although its maybe 2 or 3 years old now the drive hasnt had much use as I replaced it on my main pc within a year of having it and barely using it.
