So about a week ago I had a 2TB drive fail on me and all attempts to recover either the drive or the data were not successful. Thankfully out of all the drives I store media on it was probably the least important as it was 2D rips of a bunch of my 3D movies so they are recoverable, but it will still be a bit of work.
After giving up on the drive I did start seriously thinking about the condition of my other drives so I ran a check using Crystal Disk Info only to find that 3 of the 12 drives I have remaining have issues and Crystal Disk Info flags them with the big yellow "Caution" flag.
At that point I decided I have ignored any sort of disaster recovery plan for far too long.
My storage setup is comprised of 2 Mediasonic ProBox H82-SU3S2 8 Bay External Hard Drive Enclosures that are attached via USB3.0 to a Windows 8.1 rig. Currently I have 4 2TB drives (Green) and 8 3TB Drives and 1 6TB drive that is on the way to me as I write this. Of the 29TB of real storage that I have I would say I am at about 80% used, it is all movies and TV shows.
With that percent of used space I am really on the side of a solution that I can add non-empty disk to to save me trying to move data around for days, or more, to get free drives to keep adding to an expanding storage pool.
I did look at Windows Storage Spaces, but besides the fact it has to format your drives the user comments I was reading were about 50/50 on the bad and good.
I have been reading a bit on DriveBender and StableBit DrivePool.
A few years ago I had tried FlexRAID but found quite soon in that, while it was great for pooling, the "backup" processes that would occur overnight were not even getting close to complete before the morning. Did post that on the FlexRAID forums and it was attributed to the drives being in external USB enclosures.
I am not looking to replicate the media, mirroring, but rather something along the lines of using parity drives and at least right now, a Windows solution.
Would be appreciative of insight from the MB masses on what they are doing\using to protect against the unavoidable drive death.
