Just wanted to report back about my adventures with the Blinking REC of Death or BROD.
So I went ahead and tested out the secure erase and partitioning with Parted Magic and have had no success so far.
At first the problem was that I was using my iMac with bluetooth keyboard and mouse and since they are not recognizable under the Parted Magic interface, I could do nothing while in it. Then I went digging around for an old USB mouse but couldn't do much because I needed to type in some numbers while partitioning the drive. (I didn't have a USB keyboard). I don't recommend trying to use bluetooth interface while in Parted Magic. Maybe someone smarter than I can relay how to use it.
*note: for those who don't know, understand that Parted Magic is a linux interface and acts as its own operating system of sorts. Then I thought why not use my laptop since mouse and keyboard functionality is built in obviously. After booting from the Parted Magic CD by holding down C on the keyboard while booting up, I was able to access my 480 GB Sandisk Extreme SSD and secure erase it while in Parted Magic.
I then used the Partition tool to partition the drive as recommended (365 GB) but I couldn't figure out the disk allocation so I skipped that step. Maybe someone has a lead on how to do this on Parted Magic?
After all that, I put the drive in the camera and started shooting 4K RAW only to get the blinking REC (dropped frames) after about 10 seconds and sometimes 1 minute at the most.
Then I tried using TRIM enabler as Robert suggested and had a minor success! After enabling the TRIM on my SSD, I was able to record over 2 minutes without dropping a frame. It was my longest RAW shot to date but alas did not fix the problem entirely. After that 2 minute shot, I tried recording RAW again and I got the blinking REC after about 10 seconds again.
In either case, I just wanted to let everyone know that my endeavors in trying to eliminate the Blinking REC of Death have not yet brought success.
I will continue to to try but I have a feeling my particular drives are just not fast enough to record 4k RAW.
