Can rebooting computer manually hard computer/windows?

post #1 of 6
Thread Starter 
Can it create errors in the windows by abruptly shutting down the computer manually?

What about, when you manually hit the "restart" button on your computer case , as opposing to completely "shutting it down" (i.e. holding the power button down), can that harm it also?

What is more prone to damage if so? the hardware? or software (i.e. windows?)

thanks?

The hardware won't damage, but you might get file system corruption.
Always use the ShutDown/Restart option in your Windows.

if it is a hardlock, your only option is to cut power and force a shutdown.

if the system is running, if you press the power button once on the front of the case, most of the time the OS will send the term signal, and power down like you would if you clicked on start/shutdown. now if you hold the button for 5 to 10 seconds (different on each computer.), it will shut off like if you pulled the power cord or flipped the switch on the psu.

i've never known any hardware failures due to shutting off power in such a manner (unless there is a power outage and then you are hit by a surge.) it is usually the software that takes a hit, most OS's file systems are volatile to forced power offs, thats why they aren't recommended, they can become severely fragramented, corrupted files, and data loss (if it was in the process of writing a/to disk.)

some file systems come with tools to recover from a majority of these problems, for windows, chkdsk can usually recover, in linux there are various tools to check and fix errors. now the biggest problem you face with forcing a power down in windows, is of course, registry corruption, and that is very difficult, if not impossible to correct, sometimes you can do a roll back and fix it, but if the rollback got corrupted as well, then you will need to reinstall.

in linux, if you are using a journaled filesystem, and the journal gets corrupted, you might need to reinstall as well, depending on the amount of corruption there is.

It can mess up a RAID no? With Write Back Cache enabled?

are you asking or making a statement?

if it messes up a raid, does it make the harddware unusable or just forces a reinstall of the raid?

Just making a statement with room for correction... As I understood it, there is a possibility of RAID corruption, which would result in possible data loss, but no physical hardware damage.
