Whilst I have been using CD/DVD Speed to scan disks for a while now, it’s only in the last week that I ventured into the ‘Create Disc’ tab. I was trying to diagnose a misbehaving Plextor 755SA and comparing the results to the smooth curves produced by the Liteon drive.
After many wasted hours and blank disks, I concluded the drive was a lost cause and replaced it with a Pioneer 112D. Out of curiosity, I wondered how smooth a curve the Pioneer would produce.
I have another 112D in the other PC (ASUS, XP2800, 512MB), so repeated the test on that one.
And finally, The King of Quality 755A (Shuttle, Barton XP3000, 512MB).
All of which leaves me to conclude, either -
a) Three of my drives are slightly broken. Although, they do still produce above-average scans.
b) The smooth curve is irrelevant. However, if that’s true, what’s the point of the test?
c) I should get out more.
The main reason for pursuing this is to figure out why random (TYG02/03) disks become unreadable after a couple of months. We’re not talking a huge number, possibly 2-3% and even then one of the other drives will usually still read them for long enough to copy it onto another disk. However, the memory of losing 100+ disks within three months (Ridisc RITEKG04 and Imation FUJIFILM03) does not fade easily.
PS - I tried using the Benchmark tab as well, but after watching it patiently reach 100%, it keeps blanking the screen before I can save it.
