While trying to
troubleshoot my friend's dying empeg, I managed to lift IDE header pads on my spare empeg.
How can I remove the IDE cable from the motherboard without damaging the IDE header?
I attempt to raise the cable "straight" off by gently pulling one side at a time, alternating between sides. However, I always have trouble with the left side (by the display cable). There's nothing to rest my left hand on to get leverage, while my right hand rests on the side of the case. Sure enough, I apply awkward pull to the left side and I broke the traces there.
I knew this empeg had it coming. When I first bought it, I noticed weak header solder and bought a longer IDE cable. It only took maybe 10 removals of the cable to pull the header.
For the record, these were my symptoms indicating degraded physical connection with the hard drive:
It lags on boot at the "Partition check:", saying "hda: lost interrupt". It sometimes shows "hda:disk error: status error" the screen after boot or while playing.
During a drive today, the music would stop randomly for a random amount of time (between a half second and five seconds), then continue. During the pause, the UI was not frozen. I could pause and start playback to immediately resume, or switch tracks to resume playback. When connected to hyperterminal during playback, the lag coincides with a "hda: lost interrupt" error.
Here's my boot log. Playback has paused a few times (the last few lines).
