^I'm only drawing conclusion from the statement.... this is the 1st time i've even heard of the term. Since The disks can take upto a million of parks then i suppose it doesn't really matter.
limefc:
Basically read heads are held above the surface of HDD platters by the airflow generated by rotation, parking lands the read heads off the platter(s). The action of moving them back over the platters from parked state can cause potential damage and head crash.
It's very similar to turning the HDD on and off a lot. That also causes reliability issues.
A HDD is most reliable when it is working 24/7 365 days a year with 0 downtime at a constant temperature between 35 to 40 degrees.

You mean I am reducing the life of my hard disk by turning it off for 16 hrs a day and using it only for 8 hrs during the night? :o
My purpose is to stream anime off it, storage and seeding.
limefc:
Yes, you are. That's 2 start/stop cycles per day and 16 hours without positive internal pressure which potentially allows foreign particles to get in.
That's about average usage for a HDD though, it shouldn't last less than 3-4 years unless you get unlucky. It's much worse if you have your HDD turn off while idle in addition to power cycling it twice per 24 hours. That'll really fuck up the spindle motor.
Personally I have 3 hard drives working 24/7 under controlled temperature and 1 hard drive which is turned on/off only for bulk transfers less than once a month. The only one I am worried about is the one for bulk transfers. I've had HDDs shit the bed several times after long term storage.
Dhruv:
Okay lemme tell you my complete situation
I turn on my HDD at 2 AM and turn it off at 10 AM
Sometimes(once or twice a week) dad turns off it's usage by shutting down my downloads and uploads as he has to see the share market during which the hard disk is turned on with power but is not in usage for transfers.
He does this during the daytime too but my external isn't connected at that time
So what do you recommend?
I should use it 24x7 or like what I am using it right now?
Of course I maintain the temperature by switching I the fans of the room.
