I have just burned two very poor disks with GS0F firmware.
With the older GS0C (was firmware in drive when shipped) I can burn RitekG04 (DVD-R 4x) and get great Kprobe results. The disks also work well, and pass a read speed test with little or no ‘dips’ in speed.
Good scan attached.
After ‘upgrading’ to GS0F, ive tried an 8x burn on some 8x media (LiteOn brand, RicohJPNR02) which works very well both in read speed and Kprobe results.
Then i tried some more burns on the RitekG04 media, at 4x.
The results are shocking. This is the same batch of disks - one is a coaster, the other barely reads.
So i reverted back to GS0C and tried another burn - it works fine, the scan shown here is from a disk i burnt after i reverted.
Has anyone else seen this behaviour?
