Are Newer And Faster IDE Drives Troublesome?
viperjsw writes: "Earthweb is running an interesting article on how there seems to be a failing trend in newer 7,200 RPM IDE hard drives. I am the lead hardware engineer for my co with four thousand 7,200 RPM ATA100 Maxtor and IBM hard drives. I have not seen any failure trends, though failure rates are at about 5-10%. Are Earthweb's reports verifiable?"
Also, with a faster speed, the spin-up will be more harsh on those drives.
I wonder how the failure rates of 10,000 and 15,000 rpm SCSI drives compares to those of lesser speeds.

7200 RPM drives run hotter than previous drives, and they must be cooled. Previously people rarely gave a thought to drive cooling, and if they don't take it into account now they will see large failure rates. If your drive is too hot to touch after running for an hour, then you need to cool it off.
I've been installing 7200 rpm IDE drives into servers and workstations for well over a year now, and the only complete failure I've had was one that didn't work from the start. I've had drive errors crop up from heat (put a fan in, seperate it from other equipment (don't sandwich it between the floppy and zip), etc) and from using a 40-wire IDE cable instead of the ata-100 80-wire cables.
FWIW, I've used Fujitsu until a few months ago, IBM, Maxtor, and few seagates. They have all been at the lower end of the price range ($99 wholesale - went from 10G to 20G and currently using 40G).

Lack of cooling is certainly an issue with 7200 rpm and faster drives. Since installing fans on all my hard drives, the number of failures has gone way down.
However, there is a more troubling issue:
How is it that you can now buy a 40 gig hard drive for less than $100? Simple -- the manufacturer cuts corners on quality and cranks them out by the thousands in third world sweat-shops.
IBM is now putting disclaimers on some of their hard drives, not recommending operating them for more than 8 - 10 hours per day.
Where would I find reliability ratings for disks?
Actually, for me, two year old models should be fine. 40 Gbytes is way more than I need for most of my systems. But, I want a new drive, not one that's been sitting on a shelf for 18 months. An old drive probably has some new failure modes, hardening of the lubricants or something.
On a somewhat related note, does anybody have any experience with drive problems resulting from the physical mounting of drives at unusual angles (i.e., at a 45 degree roll or pitch, rather than horizontal or vertical)? Should one expect higher failure rates, or lower drive lifespans, as a result of unusual mounting arrangements?
:-)
Manufacturer specifications always state that drives must be mounted horizontal or vertical, but who ever pays any attention to the manufacturer....
Similarly for CD and DVD drives - are there any potential problems with mounting these drives at an angle? I have played around with mounting drives at angle; the drive trays etc seem to work fine when the drive is on an angle, but it is difficult to test long term performance or failure likelyhood when you only have one drive to play with.
The reason I'm interested: I'm working on a case mod, but it looks like I will have to mount the drives at wierd angles to accomodate the case geometry...
