So I've been running a file server using a RocketRAID 2300 with 4 2TB WD Green drives in a RAID 5 for the past three years. A few weeks ago I started noticing some performance issues starting to happen: Slow transfer speeds, video freezing, etc. when accessing the data over my gigabit network.
I opened up the controller's web management software and saw that one of the drives was reporting 231 bad sectors found and repaired, while the rest still had zero. I tried running a "Verify" task on the array multiple times but each time it would eventually stop responding (the raid management software wouldn't even open). Eventually I would have to restart.
Newegg had a 2TB Green drive as a ShellShocker deal last week so I figured it would be a good time to replace the drive with the bad sectors, hoping it would solve my problem. I replaced the drive Tuesday night. When I booted up my system the RAID BIOS screen at startup listed the array as Critical and I added the new drive to the array and continued on to Windows. Once Windows was running I opened the RAID management software and saw that it had automatically started a Rebuild like it was supposed to.
The next day around noon (15+ hours into the rebuild) the software still said 0% complete. I tried to reopen the software and again it would not respond or open, just as it did before when I tried to run a verify task. It's now been three days with no response as Ive just been letting it run. It appears to not be doing anything right now, the most recent entry in the raid management log is the "starting rebuild task" entry from Tuesday night. I was able to backup all my data from the array beforehand so I'm not at risk of losing any data thankfully.
Could this be a bad controller card? I don't know what else to try. I'd hate to drop the cash on a new card if I wasn't sure.
