I've got a very unique and annoying problem.
I had a RAID 5 array of 4 1TB disks. I have a bunch of very important info on there (like 3-6 months of work). I backed up the parts I can't bear to lose but I can't back up the over 2TB of data that I would just really really not like to lose.
Anyway, I wanted to expand the array and add another disk. I'm using intel matrix RAID so I just put another disk in, modified the existing array to expand it, and let the expansion begin. This was looking to take about 2 days or something crazy so I didn't pay close attention to it.
In the first half hour of the expansion the computer crashed. I booted back up and found that two of the disks in the array (not the newly installed disk) were marked as failed and thus the whole array was marked as failed. This seemed super unlikely to me that they physically crashed.
I marked the two disks as safe and it asked if i wanted to reinitialize the array. I said OK. This took about 8 hours. After it was done i could see all of my files but couldn't open any of them. I restarted and windows did an extensive disk check (took an hour or two) and said it fixed a bunch of orphan files. Now I can again open all my files but they are corrupted in a very unique way.
Each file has a bit of it's data, then a bit of another files data, then a bit of crap, etc. Probably like you might expect from a RAID 5 array data storage pattern.
It seems there has got to be a way to get my data back since it looks like it's all there just spread out between all the different files. I'm guessing that the data is still constructed in the manner it would be if I had only 4 disks as it didn't have nearly enough time to expand the array. Can I trick it somehow into going back to 4 disks? Any other suggestions?
