This article has no citations for the many claims made. Is this normal and acceptable for this type of article?
Possible advertising, but more importantly some information there is dated. Would be an excellent reference if current, but some assertions at the link are not true today. For example, Fujitsu continues to make hard disks; several 300 GB SCSI drives are listed on eBay at the time of this writing. Marc W. Abel 20:17, 27 June 2007 (UTC)
Agree. Information is extremely outdated and subjective. Zzptichka ( talk) 14:23, 26 October 2008 (UTC)
A rather bold statement saying that CD and DVD can fail in a drive. I have yet to find any evidence of this.
I'm confused why the DVD and CD-ROM pages don't mention the NIST study. Also, the DVD article seems to have different numbers and the CD-ROM page doesn't mention lifespan at all. This is all confusing to users like me who want to backup stuff but who research online and find a lot of bad reviews for HDDs quickly going bad all the time and seemingly random numbers for CD and DVD lifespans. It sounds like printed media like photographs last much longer. Thank you for adding what was available at the time. I hope more research can be done by organizations in the near future.

From "Disk failures in the real world: What does an MTTF of 1,000,000 hours mean to you?" ( http://www.usenix.org/events/fast07/tech/schroeder/schroeder_html/index.html ) section 4.2 (Age-dependent replacement rates):
"One aspect of disk failures that single-value metrics such as MTTF and AFR cannot capture is that in real life failure rates are not constant [5]. Failure rates of hardware products typically follow a "bathtub curve" with high failure rates at the beginning (infant mortality) and the end (wear-out) of the lifecycle."

Perhaps the article could make mention of tri-axis accelerometers (eg Kionix KXPB5) used in some laptop drives. These are in addition to the normal shock sensors.

I came here looking for some percentages, like what are the actual causes, for instance to compare how much of a role wear and tear play. I'm playing around with some ideas for customized RAID setups for fun, and I'm not sure to what extent I should be spinning drives down vs. scrubbing them as part of the algorithms. This article is pretty worthless overall. Imagine an article like this one called "Automobile mechanical failures": list all the parts, and yes, they can all fail. 198.179.82.133 ( talk) 16:51, 18 October 2013 (UTC)
Hello, I am currently on a computer (Lenovo) on Windows 8. However, when I plug in the drive, the drive does not seem to be found, no matter how long I wait. When I plug it into another computer, it seems to work. Why is this? 107.217.169.253 ( talk) 19:54, 28 December 2013 (UTC)(A)
I suppose you can call this a bathub, although the dip in the "tub" is pretty small. 86.121.18.250 ( talk) 20:23, 5 January 2014 (UTC)
It was found that the HDD hazard rate function doesn't follow the traditional bathtub curve, but manifests itself as an increasing-decreasing-stabilized pattern. Furthermore, its time-to-steady-state is not one year as historically assumed by the industry. As it turns out, the generalized Gamma distribution is a better candidate to characterize the HDD non-traditional bathtub curve than Weibull and other non-Weibull parametric models

The following statement in the "Data recovery" section is a myth:
"Specialised companies carry out data recovery, at significant cost, by opening the drives in a clean room and using appropriate equipment to read data from the platters directly."
Spin-stand Microscopy is not used by any data recovery shop simply because it would be astronomically expensive, even if it were possible on modern high density drives. The only procedures performed by DR shops are head replacements in those cases where one or more heads have failed, or platter transfers in cases of seized or worn spindle motors or bearings.
The following site has video tutorials which demonstrate the procedures involved:
