I just built my first PC less than a month ago. I have a SSD drive with my Windows Operating System on it, and I have two Western Digital Caviar Black 2TB 3.5" 7200RPM Internal Hard Drives (WD2002FAEX) configured in a Raid1 to store my documents and media.
Everything worked great for the first few weeks but now I have a problem. The Raid1 has suddenly become VERY slow. It takes almost a minute to open a folder and duplicating a 100mb file can much longer than that. It is only about 25% full and is not fragmented.
- Everything on my SSD opens normally.
- I ran windows Check disk on the raid1 and it didn't turn up any problems.
- I downloaded Western Digital diagnostic tools but it will not work because my raid is listed as a "logical drive".
- I looked in my BIOS and Raid Utility and everything looked ok to my inexperienced eye.
