A Simple Way To Keep A Hard Drive Spinning with FCP

I have several hard drives that for whatever reason, likely their firmware, will spin down no matter what you tell them otherwise in system prefs, their own generally useless software or anywhere else.

This old tip still works.

However, here's a super quick and simple tip to keep them spinning while using FCP 6/7:

Tell FCP to autosave to a folder on the drive that spins down.

1. Hit SHIFT + Q in FCP
2. You'll see "Autosave Vault" and a Set button. Push it.
3. Tell it to save to a folder -preferably one you make so the saves are not loose all over the drive- and done.

Almost.

You'll have to figure out how long it takes for the drive to decide to spin down after the start of inactivity. As an example, lets say you figure out it's about 15mins.

Now, in FCP hit OPTION + Q and under the first tab, called "General" at the bottom left you'll see "Autosave Vault" make sure the check box is checked. Then after "Save a copy every" set it to something less than the time you figured out for the hard drive spin down. In this example set it to 14mins or 10mins to be safe. Hit Ok.

Adjust the other options under Autosave Vault to you liking. I like to set "Keep at most" to something between 20 to 40 depending on the importance of the project and how complex it is and the rate of changes I make to it.

This is actually important. Save files for FCP 6/7 are HUGE XML files. Huge. You can easily get into the multi GB range in terms of size. They're highly compressible though which is great. So if you keep too many saves for a project you could potentially fill up a lot of space on a drive fairly quickly.

Hard Drives Wake Up and Spin Up For No Good Reason

With Mac OS X sometimes hard drives that are attached will spin up for no reason, when open/save dialogs appear, when quitting an application or when unmounting a .DMG.

Here's a little tip to reduce some of this, mainly the completely random wakings/Spin Ups.

It involves a little Terminal magic but it's not too bad.

Keeping Hard Drives Spinning for Free (and fun)

I've been "in the field", literally on-location and during setups I get bored. No internet per se, and not many games on the laptop I have sitting here. I've noticed that the external hard drives here will spin down after 5mins or so of inactivity and it's annoying to have to wait for them to spin up when I decide to do something in FCP, so I tried a few things to keep them spinning.

There are things out there like Disksomnia which are FREE and work but if you don't have internet and are as bored as I am you wanna start messing around.

One simple (yet fairly inefficient) solution I found was to have Quicktime Player loop a file that's placed on the drive that's spinning down.

1. In FCP drop in an audio Slug. Video Generators > Slug
2. Export it as an .aiff to the hard drive that keeps spinning down.
3. Open it in Quicktime Player and set it to loop (Command + L).
4. Hide Quicktime Player (Command + H).

It's not efficient because while it works silently in the background it will eat up a significant bit of CPU if you check it with Activity Monitor; but still, it's free and something that can be done with (arguably if you have the now optional QT7 install, installed) what you already have.

Hard Drives Keep Spining Down

Western Digital MyBook external drives are notorious for having a mind of their own (firmware) which spins them down seemingly every other minute (actually every 10mins). During a 60min export a friend called and asked me why it was failing repeatedly seemingly in the same location. Could the files be corrupted somehow? Asking about his set up I knew the problem when he mentioned there were two WD external drives connected to the system.

There are a few things to you can do to stop this.

01) Boot into Windows and alter their firmware with Western Digital's own tools. Good luck with this.
02) Pay $10 for No Spin. Which I haven't tried.
03) Install the FREE Keep Drive Spinning but under Snow Leopard it'll require Rosetta.
04) Download the FREE Disksomnia, which I've mentioned before, but in order to download it you must provide your email address (they email you a link to download it...evil) which opens you up to spam, their newsletters and other junk. Also, the Disksomnia installers requires your admin password which I never like. Pacifist shows that all it installs is the app and then sets it as a log-in item.

I don't like log-in items and just need the app. Yay for pacifist.



05) Mac OS X Hints has a Bash Script to keep the drives spinning. Your luck may vary with this.

This has become such a bother for me that I'm no longer using or accepting WD External drives for editing from clients.

Some suggestions I've received are essentially variations on the same idea: Put a media file on the drive and keep it playing in a loop. Small .mov, .mp3, etc...
