PDA

View Full Version : Drive orientation - If it doesn't boot horizontally, tip the case?

Background:

I run standard cases that mount the drives horizontally. I don't run SATA at home, but I do run PATA and Ultra-SCSI320 drives at home. I've been on a big project for the last two years, and now have more time to futz around with my home PCs.

Anyway, two of my PATA drives went belly up, but while drunk, I was "inspired" to tip the cases because the drive noises that were made when the boxes were booting reminded me of old POST 1701 errors.

Way back in the day, some lubricants would get too thick over time, so what we would do was run the power, drop the CPU an inch or two, get it to POST ok, and then exercise the drive overnight.

In case it helps anyone, try running the drive vertically, and don't be afraid to slap it (if it looks dead already, you have nothing to lose). I've gotten all my data off and have replaced my drives, but because two boxes were affected, I really doubt that it's a coincidence.

One drive is a WD and the other is a Seagate. I'm going to contact their support to see if I can get an RMA out of warranty if they want to study it, but I suspect that it's something that the sharp folks (not the ones you get on the phone) are aware of the problem and that both companies are hush-hush about it.

The drives are perfectly usable in a vertical orientation while in an enclosure, so I don't want to rip them apart just to see if they have common guts (main disk motor, actuator motor, voltage regulators, other components, etc).

On an off topic, I noticed that my company's SANs (BIG Sun-branded Hitatchis - think like 45 TB) mount the drives vertically.

If anyone else got a "bad" drive to work after tipping the case, I'd like to hear about it out of curiosity.

Nope I have never gotten a bad drive to work from sitting it verticle. I have gotten a few to work by putting them in the freezer overnight though.

It *shouldn't* make a difference. But hey, whatever works.

Don't ever slap a HD. Why would you EVER want a magnetic head to impact a metallic or glass disk rotating at 5400, 7200, or 10000 RPM?? Physical impact is the only thing you'll accomplish. Pings on platter surface do not a data recovery make.

Your WD and Seagate drives will have exactly zero interchangable parts (aside from diodes/resistors/capacitors). Heck they may even rotate in opposite directions.

Someone should slap you for suggesting slapping a hard drive. It's suggestions like these on forums that make it that much more difficult to get data off drives...

There's no big conspiracy, HD manufacturers are well aware their drives fail, and yes, HD's can do some quirky things at time in how they work and how they don't.
