Omitting the key information is bad
A forum member goes to great length describing a hard drive problem, which sounds mechanical. Then follows a precise account of what they tried to fix the problem, including the fact they replaced a PCB from a same model drive and so on. The story goes for like a full page, still the actual model of the drive is never mentioned. In this case, the model number is probably the most important piece of data, because we can look up a typical failure modes with it.
