Raid issues, not sure what happened

post #1 of 2
Thread Starter 
I have been running a software raid 5 array for a few months and today while transferring about 16GB of data i noticed that the transfer time was around 20 hours or so, i opened up my windows resource monitor and discovered that the array was actually running at 5 MB/s, when i normally see 60-150 constant read/write.

Thought it might be an io problem so i killed every system and process that was not needed still no change in the performance. Then i opened up windows disk management and I found a 3TB drive that is showing up as un-allocated, but should be part of the array. Is it possible to have a disk kicked out of the array?

What i have done:
-killed all extra running processes
-re-installed latest intel rapid disk management
-ran a few benchmarks on it anywhere from 150kbp/s to 5MB/s
-opened up windows disk management and found an extra 3tb drive that is un -allocated ( there shouldnt be an extra one )

Not sure what else to do from here, i can still access the array but pulling data off it is going to take a few days at those rates.

Pc hardware:
I have a ASUS P9X79 WS along with (3) 3 TB seagate drives

any troubleshooting suggestions will be appreciated
