The interest in Seagate ST-27x drives revived my intererest in a project I've wanted to do for a while, to collect flux samples of RLL hard disks. A friend of mine got
a Maxtor XT2190 that appears to have been written with an RLL contoller. The problem is there is very little information on what that encoding actually is, so for the
last couple of days I've been formatting drives with various AT controllers that I own and have been collecting samples, along with making a list of controller read
performance. The performance is pretty bad, especially the WesternDigital controllers.
Data is up here:
