Comments noted, thanks.
As mentioned previously, I am pretty certain there are no scratches, scuff marks, or any other obviously noticeable defects on the disc. Plus there is no evidence of dust either.
I was thinking that the printer installation disc may be a “weak” pressing; the data on the disc is not properly impressed into the media. This means that it would require drives with “strong” reading lasers in order to read the weak data from the disc.
It is suspected that the GGW-H20L might have a weak (CD) reading laser, which means it would have difficulty in reading weak data from the disc.
Basically, weak data + weak reading laser = reading problems.
I was also thinking that the pressed disc data may be out of alignment or out of (nominal) spec, just enough to cause reading issues in the GGW-H20L which may have its CD reading head slightly misaligned as well(?)
So, misaligned CD data + misaligned reading head = data reading issues.
Or, maybe a combination of both of the above -
Weak and misaligned data + weak and misaligned CD reading head = definite data reading issues.
As mentioned previously, the GGW-H20L seems to read other CD and DVD discs fine (so far), fortunately.
