#297733 - 29/04/2007 22:25 How to remove IDE cable without breaking header traces?
FireFox31 pooh-bah Registered: 19/09/2002 Posts: 2494 Loc: East Coast, USA	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). empeg-car bootstrap v1.02 20001106 ([email protected]) If there is anyone present who wants to upgrade the flash, let them speak now, or forever hold their peace...it seems not.

tfabris carpal tunnel Registered: 20/12/1999 Posts: 31578 Loc: Seattle, WA	My guess is that in the process of swapping stuff around, enough yanking and replugging of cables has loosened something up, like it pulled up a tab on the IDE header, or some such. _________________________ Tony Fabris

Still, I'd love to know a good way to remove the IDE cable nice and smoothly. _________________________ - FireFox31 110gig MKIIa (30+80), Eutronix lights, 32 meg stacked RAM, Filener orange gel lens, Greenlights Lit Buttons green set

mlord carpal tunnel Registered: 29/08/2000 Posts: 14484 Loc: Canada	There's no good way to do it, other than to not do it. The strain on the header can be reduced by using some method of prying the cable slowly, like levering it from the mainboard, rather than just pulling on the connector (which tends to suddenly "let loose" causing an unwanted yank at one end..). It's just the nature of the beast. That header was never intended to be touched beyond the factory. Bummer, eh. -ml

Being a hardware guy, I just assume I can disconnect and reconnect IDE cables whenever I want. As a side note, the IDE pads on the MK2 I'm working with have the most perfectly even application of HARDLY ANY solder. On both of my MK2a's, pads have different amount of solder ranging from "lots" to "decent, I guess". But the MK2.... wow, I'm surprised that header is attached. _________________________ - FireFox31 110gig MKIIa (30+80), Eutronix lights, 32 meg stacked RAM, Filener orange gel lens, Greenlights Lit Buttons green set

Yeah, that kind of sloppy assembly seems to be commonplace. Just in the past week I resoldered the USB connector for a D-Link wifi adapter that looked a lot like a faulty empeg header. And yesterday I fixed my USB_to_IDE/notebook/SATA drive adapter "cable" dongle thingie. It had a 3-pin tab style regulator/transistor inside that was just barely touching the solder pads. After 10 minutes use it would konk out. Duh. Cheers Edited by mlord (01/05/2007 01:50)
