Same place they are after power fails, retracted.

Where are heads when HD is being shipped? Parked???

Probably flushing the cache. Parking heads isn't a "command" that I believe applies to voice coil head actuators.

You run SRH BEFORE powering off the external drive.

I don't buy the "parking heads" thing either. Parking the heads is an "old school" thing. Modern drives park the head when powered off. Sounds like urban legend to me.

The "Safely Remove Hardware" utility that sits in the System Tray.... does anyone use that?

I have never used it. But recently a couple things came up that made me wonder if I should be using it. A couple weeks ago I was at someone's laptop and I had plugged in and later removed my USB pen drive. He commented that I should be using the SRH utility "because he had burned up a USB pen drive by *not* using it". I have several of those drives and have never had an issue... and like I said, I've never used that utility to disconnect a USB device before unplugging it.

But today I had unplugged a Maxtor OneTouch external USB drive - and did not use the SRH utility. When I plugged a different Maxtor OneTouch drive into the same machine, Windows didn't recognize it. I tried several different USB ports... same thing. So I used the SRH utility to *Stop* the USB mass storage device in there. Then I plugged the drive in, and Windows recognized it.

Just wondering what other people say about this utility, and if you use it. I've always been under the impression USB devices were hot-swappable and didn't require any user-intervention, such as using that utility

TIA

Concur with most responses, except the parking heads response.

While using SRH, I've noticed that sometimes something must be occurring even though the activity light is off on the external enclosure. SRH says something is still accessing, to try again later. Usually, an immediate retry of SRH allows removal. Seen this with both Firewire and USB2 enclosures for ide hard drives.

An oddity I've noticed about the policies tab for the hard drive within the enclosure. An old Firewire only enclosure I have uses the non-cache type selection per windows installation of same. The newer USB/Firewire combo enclosure for ide drives use the cached type that requires SRH. Don't matter if USB or Firewire connected.
