Hard Disk Myths And The Truths!
The read/write heads do NOT touch the platter surface, so damage to the platter only occurs if there is any shock to the drive during operation. No difference. I ve never found it to be an issue, though I don't have any machine downloading 24x7. Misc. have a peek here

The one question I have in respect to data recovery is; That when a HDD finally wears out as they all do. Join Now This is the 286th article in the Spotlight on IT series.

Jobs that would take weeks are now done in days, and jobs that would take days are now done in hours. The PCB was very easy to remove though, there were no cables, plugs or Zero Insertion Force things, just contacts on the PCB and springs on the drive. In addition, the hard disk drive is a sealed environment assembled under clean room conditions, so there is very little dust inside the hard disk drive. Truth : To put it shortly, formatting your hard drive will NOT reduce its lifespan.
It spins up, clicks about five times, spins down. But, as we get up in to a bit more robust technology, we start to see engineering that accounts for this and ensures the drives wear evenly, as well as manufacturers Current hard disk drives use the ramp load / unload technology, which moves the drive heads away from the platters onto a ramp where they rest, instead of landing on a http://www.speedguide.net/forums/showthread.php?245094-Hard-Disk-Myths-and-the-Truths! I was amazed on how well these old PC's functioned as workstations with this config. Just something else to think about to breath life into old equipment. 2 Serrano

Truth : Formatting is done contiguously. So, as you can see, by doing this we increase capacities and thus lower cost on a per-GB basis. We now have SSDs with capacities of up to 1.6TB today, with
Let's address those claims one by one : The platters of a hard disk drive spin at a fixed spindle speed, whether the heads are actively reading or writing, or just my site It did fix one drive long enough to get everything off, and another drive remained dead. Sigh.... Did you try TestDisk (http://www.cgsecurity.org/wiki/TestDisk) to try to recover data? 2.
Hard disk drives are like a car's fuel tank. http://zuneuser.com/hard-disk/hard-disk-failure.php Newer hard disk drives are rated for at least 50,000 start-stops, in which case, they would last at least 17 years at the rate of 8 daily start-stops. Info One is not only more appealing to me, since it fits my situation and offers some hope, it also makes more sense to me. The only thing that a circuit board swap will definitely not fix is a drive that makes grinding noises.
Although many articles have covered these topics, it is apparent that hard drive urban legends are still more popular than the simple truth.So, let's get down to basics and examine some Myth #3 : Formatting the hard drive will stress the needle (head actuator). It just reveals the presence of bad sectors. http://zuneuser.com/hard-disk/hard-disk.php However, after defragmentation, the hard disk drive no longer needs to seek all over the platters for your data.
Not an issue.This is a "myth". Once you've tried them you will not want to go back. Just one mote of dust or corrosion there would be enough, but removing and replacing the board should be enough to refresh the contacts.
This wears the drive more evenly and extends its lifespan. Remember most typical workloads are usually two to three reads per one write and reads don’t wear the cells on an

This is a bare drive we're talking about and not a drive in an enclosure, right?
Of course, in those days the heads flew at a much greater height, and areal density was a lot lower, so it might not work these days. I haven't had the first problem and my boot time is insanely fast. I would soooo be down for the cloud/sky thing too, if everything I touch wasn't ITAR controlled... 0 Thai Pepper OP CA-RT Feb 13, 2014 at 5:44 UTC this contact form They were already there, the formatting process just reveals them.
Especially now that they're less 50 cents per gig, and falling.One thing I believe to be true, which is a very important consideration: HDD's often give give some warning before they're Drive may click continuously or spin down. See Myth #37. Related Resources solved Bad Seagate hard drive.
