Schem and boardview for this?
Thought this one was going to be just a HDD bad-sector replacement (and the drive did have bad spots on it) but it's turned in to something a lot stranger.
Sometimes when you boot to a linux rescue disk you'll get 100MB/sec from the 2.5" drive (new, old, test, whatever, all the same), and sometimes you'll get 2MB/sec.
The main "quirk" is that the HDD access LED is *always* on.
Have updated BIOS from v1.10 to v1.60 which is the latest.
Have ordered a 2.5" CD/DVD caddy adapter to see if the fault is exclusive to the HDD SATA channel, or if it's all.
Anyone ever encountered something similar?
Trying to decide if I should be looking for a controller chip fault, or perhaps a socket fault... or just the signal pairs, maybe filters/caps along the lines.
