Even though I've officially passed off the responsibility for recording and posting the weekly sermon videos my anxiety remains elevated about the whole thing since the new guy hasn't been successful yet (all my fault)!
One of my biggest gaffes was unintentionally completely erasing a memory card. I had imported that day's video files to the computer already, but of course after the mistaken erasing (I meant to just remove some of the older videos) the files were not on the computer.
I spent all day fretting and trying different things, knowing that I had an "import complete" message before I removed the SD card from the computer. Finally I stumbled upon Disk Digger, a free piece of software that I was able to use. I think I just did it on my PC instead of the church Mac, and it really was free (unlike a lot of the other utilities that come up with you search for "restore SD card" or similar).
Between every file you had to do two clicks to continue, although the option to pay and do all the files at once was available. I wasn't sure it would work so I didn't try paying. Finally I realized I could just do the last few files in the list (I only needed videos from that day), and it worked.
I was so delighted and a huge weight lifted off my shoulders. I've had more video-related anxiety since then, but I'm hoping by passing on the responsibility that will decrease or maybe go away all together. I'll still serve as back-up for recording and processing (the new guy has his own Mac/iMovie so didn't need to use the church computer -- rats!).
So I recommend Disk Digger if you delete an SD card or important file from a drive. And I should probably pay for the full software in gratitude, but a praise-filled blog post will have to do!
