Was it the manufacturing defects or caused by improper shutdown? But it seems to be a myth that improper shutdown would caused bad sector
The most common cause of it is moving/knocking a computer when it is still on.
An improper shutdown if anything will cause loss af data, settings you have changed, things you were working on etc but i dont think it would cause a bad sector alhough its not impossible i suppose!
Hi,
Well I go back to the days when you had to give a command line entry to park your HDD heads :D
An improper shutdown, per se, should not damage the HDD............like the "vulcan nerve pinch" (ctrl+alt+del)..........
My favourites:
1. PC power supply on the way out.
2. Mains power spikes.
3. Heat & lack of airflow around the HDD
4. Subwoofer too close to the HDD (thud, thud, thud?)
5. EMP from other equipment (they don't like magnetic pulses)
6. Impact, whilst in use (HDDs are pretty robust when shut down)
7. Frost and humidity (left in trunk of car in midwinter :eek: )
8. Dust and crap (ever done a job on a pig farm?.........the dust from the feed kills CDs, floppies and HDDs...............garages and engineering works are as bad......oily fumes?)
Just a few suggestions............OK all HDDs have some surface flaws, but these are quarantined at time of manufacture.............I am talking degeneration and catastrophic failure here.
Cheers
Good Day,
Just couldn't pass this by, especially after Nihil mentioned parking our HDDs at the command line. (Don't we still do that?) So here's 2 cents worth from the ole school. :)
Hard Errors are problems with the disk surface itself, in that it cannot record your data on that area. Nihil mentioned some good examples of things that create a “Hard Error”. Most of them are caused by abuse after the manufacturer. And obviously there are some HDDs that left the factory with bad areas. Those areas have already been cordoned off and marked as bad and data will not be recorded there.
Soft Errors are problems that occur when your data on the HDD has faded to the extent that it can no longer be read. I haven’t experienced any “Soft Errors” yet, but format would redraw the sectors for you and you would need to re-install your OS afterwards.
cheers
Acts of God like lightning, or improper handling of hdd like knocking of banging the hdd, or with strong magnetic field around the hdd + heat problemsQuote:

hummmm,
Just an observation, however, isn't that what Nihil had said: :eek:
Nihil: power spikes
You: like lightning
Nihil: Impact, whilst in use
You: improper handling of hdd like knocking of banging the hdd
Nihil: EMP from other equipment
You: magnetic field around the hdd
Nihil: Heat & lack of airflow around the HDD
You: heat problems
:D
cheers
