When a 2.5" HDD + USB3.0 enclosure case is removed the USB3.0 cable of PC that powers the case, how many seconds does it take for the read/write heads of this HDD to enter parked mode?

We had this exact discussion last week.

What answers were insufficient?

This will likely be closed.

There is no single technology for how drives will park the heads.

As shown earlier, some use a spring. Once power is lost, the spring takes over and pulls the head tot he parking area.
Other drives use the spinning rotation.
With external enclosures, a lot of them have a g sensor. When detecting a fall, it cuts power and the drives internal parking tech takes over.

There are probably other methods.

There is no single method or timespan.


Again, all this was covered before.

Closing this one.
