There seems to be something wrong with my 451S… the firmware or the drive itself is wearing out, it just doesn’t seem to want to do 4x on +RW discs anymore. Right after a got it and before too much use, I used to be able to write nicely like this at 4x:
For the sake of consistency, all KProbes will be done with the drive as a 451S GSB6. Yes, this did mean switching firmwares between each write and scan.
Shortly afterwards with a bit more use of the drive I flashed to the 832S firmware, VS08 and subsequently VS0A and noticed something very very wrong happened:
A 2.4x write:
And a 4x write:
Now, I’m not scanning the whole disc, otherwise it’ll take a really long time. In some cases, the drive refuses to scan at higher than 1.0x.
Things look more promising when using the 451S GSB6 firmware for writing.
At 2.4x: (the outer, say, 0.1% of the graphs have been chopped off as they contained poorly written sectors from other poor writes)
I can’t seem to be able to get those nice results at 4x anymore:
(What exactly happens at 25% there?)
Is there any way to grab the writing strategies from the GSB6 media and patch them over to the newer 832S firmware? Or my drive wearing out? Actually, I’m really confused by all of this. In a moment I’ll post a scan (451S write) of another lesser-used disc from the same pack.
