Sorry to be the bearer of bad news but Ritek G05s seem to be doing the same thing that the G04s did. The first scan below was burned and scanned in May of 2005 and is typical of the scans I was seeing from this media when burned on an NEC 3500.
The second scan below was burned on May 5, 2005 on a NEC 3500 with 2.18 firmware at 8X. The scan was done today.
Needless to say, I am reburning all of my G05s. I checked about 12 out of 50 and found increases in errors similar to those shown below. Out of curiosity I checked my Prodisc S03s as I have used hundreds of these and I found no problem.
I’ll be checking all my Ritek media very soon. 3 month life is a little low for my tolerance. These were purchased from Newegg in April, and are Ridata branded on the hub with matte silver tops.
