Refreshing Hard Drive Storage

Larry Jordan has recently been warning against the dangers of leaving drives on a shelf for periods over a year. He says that after a year, the data will start to essentially disappear. There's a way to avoid this effect of the vanishing data, and that's to have the computer read the entire disc.

Larry just posted an article on how to do this preventive action on his recent newsletter (not sure if this link will work for long, as these newsletters are only available for a limited time.) Here's the basics of the preventitive action.
-Make sure your user account has administrator access
-Open the Terminal applications, which is in the Utilities directory
-Enter this command: sudo cat /dev/rdisk0> /dev/null
Actually that command will read your entire boot drive, which is probably not the drive that has been sitting on a shelf for a year. You can run this task on different drives, but first you have to figure out the identifier for the drive (hint: it's not the name that you called the drive.)

To get the disk identifier, go to Disk Utility, also in the Utilities folder. Select the drive, not the volume--the drive's name usually starts with the capacity of the disk followed by the drive's manufacturer, e.g., Seagate, Hitachi, LaCie--the volume is what you named the drive or a partition on the drive. After selecting the disk that you want to run the maintenance on, click on the info icon at the top of the application window. This opens a new window with info on your drive, the disk identifer is the word "disk" followed by a number. If the disk identifier was disk2, then your command would be: sudo cat /dev/rdisk2> /dev/null

The command will take a while to run--we're probably talking hours. You can interrupt this procedure by hitting Control + C while in the Terminal.

Disappearing data is only one risk you run by using a hard drive as long-term storage. But this seems like something worth doing if you care about the data that you have left on a drive.

Blu-ray Burning with Toast 9

"Taming the Wild Blu, yonder... " By Bruce Nazarian

"Taming the Wild Blu, part 2..." By Bruce Nazarian

Two good articles that cover the Blu-ray burning featues of Toast 9 on Macs. The first article covers the basics of burning Blu-ray and has a good tutorial on burning a Blu-ray data disc. We are currently using Toast 8 to burn Blu-ray discs to archive movies and old FCP projects as data. For some reason, I can't get Toast 9 to recognize our burner, but Toast 8 works fine for this--this tutorial will still help if you are trying to figure out how to burn a BD with Toast 8. There's a new version of Toast 9 out, 9.0.4, which I need to try out--hopefully the problems with the BD drive will go away. Recently, I blogged about a video tutorial that covers similar ground as this article.

The second article gets you into creating a Blu-ray discs with high-def video. So you've got your snazzy HD camcorder, but how are you going to playback your next high-def project? Apple isn't really helping you out--you can't playback video from Blu-ray discs on your Mac (much less author a Blu-ray disc with their software.) But this article points out the other options, namely Blu-ray players, which already cost less than $200.

Toast 9 does basic authoring of Blu-ray video discs. Simple menus, encoding of video to MPEG-2 or H.264, and, of course, burning your Blu-ray disc (or even regular DVD if you have about 20 minutes of video or less.)

Don't forget about Adobe's Encore CS3, and now CS4, which I blogged about earlier this year. Encore has a much more sophisticated tools for authoring Blu-ray discs than Toast's. But for simple discs, Toast looks like an easy way to put your high-def video onto disc.

Just for Fun: Digital Conversion PSA Spoof

This is a funny video about how your average grandmother will handle the conversion to digital TV. The sad part is that there are really going to be a lot of older people out there who will lose their TV when the old analog stations turn off their over-the-air broadcast. Well, I guess it's a growth opportunity for Link--think of all the dishonest satellite salesman out there who will get granny to buy Dish or Directv when her shows disappear come 2-17-09.

Is Your Video Looking Rough Around the Edges?

"Am I Rendering And Viewing At The Best Quality With FCP?" By Andrew Balis

This is a very good article over at kenstone.net. This is a topic that I sort of took for granted that I knew everything that I needed to know about rendering--then I find out features that I didn't even know about. One of these is the audio mixdown vs item levels rendering. There was also a setting for HDV rendering that I had totally misinterpreted the meaning of--it would cause me to have to re-render all my HDV footage, which takes a long time.

The article points out that the quality of real-time previews sometimes isn't as good as rendered quality. I used to see this everytime I did Latin Pulse. I like to use dissolves on title clips. If I had a color-correction on the video below the title, then the title would drop to half-resolution even though the timeline said it should be "Full Quality." So I would have to go in and render all of these little dissolves or change my settings to render out everything that should playback at "Full Quality."

So if you want your video to look as good as possible and your audio to sound as good as possible, I recommend this article.
