Consumer hard drives like a good hammering

The information seems a bit general...but interesting in that it revises expectations somewhat...

I've found that HDD's don't take well to hammering. They don't like to be dropped from three feet to a concrete floor, either. 100 static G's my foot.

Hehe... Has anyone actually put the shock statements to a test?

BUT, I would also say that looking back, that the artical has raised some interesting questions for me.... and would probably say that they bought good consumer hard drives, not cheep-o crap like we(I) buy.

The increased likelihood of failure after surface scan errors looks like a warning - especially for Raid 0 users.

The thought of G's storage strategy consisting of a giant jbod makes me think that maybe our data is confidential after all

A light tap has been known to fix a locked drive spindle but its very desireable that the heads are parked at the time !

Yeah, 80GB IDE hard drive. Seagate 10 series fell from waist high onto concrete, landed on the corner (brand new). Plugged it in, worked fine, now coming up to 8 months as a Windows XP boot drive.

The 200 gig i have fell from the bunkbed in the old trailer that I lived in, about 5' to the floor(which is made of wood) and it still works like a champ.

It was a 40 Gb Seagate that bit the dust upon contacting the concrete floor. It was brand new, I was po'd at my idjit neighbor's ham handedness. Oy, what we put up with.

100G static - think about it. How fast was the hard disk going when it hit the floor? How long did it take the disk to deaccelerate back to stationary? What's the G force implied in such a deacceleration? Depending on how padded the disk is, the G force experienced by the drive assembly can be in excess of 1000G, especially against something as solid as a concrete floor!

The old Seagate 251s and 296s, as well as the 320s and 331s used to have a terrible time with stiction, which could be fixed by rapping sharply on the drive housing with a screw-driver handle. I would call it a 'light tap' though.

Yah, concrete doesn't give, not one millimeter. A wood floor will undergo plastic deformation at the impact site. Concrete just sits there, like the rock it is.

Oh yes, thirty year old concrete has no elasticity at all. I think that particular HDD was rated for more than 100 G's of shock while the drive was off and not spinning. I learned the hard way that a rating of 1000000 G's means nothing.

If a disk is non operational and falls to the ground I might accept that it can still work. But I don't think it will do much good
But just moving a disk in operation harshly can easily send it to the eternal disk lands. If the head hits the platter it's pretty much FUBAR IIRC

TBH, it did work, but the "ticking" noise augured worse to come. Should have mentioned this earlier, my recollection was colored by the HDD's ultimate uselessness.
