I have an AMD Windows 7 system which has its OS on an SSD, and until previously had a single 4TB HDD as a data drive. I never had an issue with that drive until I installed a second 4TB drive and put the two of them in RAID 1 (using Windows disk manager)

After I finished reloading my data to the array, I noticed the array would hang randomly and often when accessing the data on it. I decided to use the "break mirror" function in drive manager to see if this was happening on only one of the drives, but once it was broken both drives are now independently having the same issue. I've tried removing one of the drives, but still had the issue with the remaining one.

I've looked quite a bit for someone else having the same issue, but haven't seen it. Does anyone have a clue what could be the cause of the issues im having?

Other info: Drives are connected to the motherboard, Pagefile is limited to 4GB and is on my SSD, Indexing disabled on drives, x64 Win 7 with updates installed
