I have a weird problem. Our main media center PC has a 120 GB system drive, 3 x 1 TB WD green drives and 1 x 2TB WD green drive. The backup system in the computer room is similar but it has a WD 1TB "black" drive for the system drive.
I level the drives manually by switcing the "recorder storage" drive from E, F, to G, to H as needed when a drive gets too close to full.
On the main MC PC, I recently switched to drive H (the 2 TB drive) and noticed if it was recording even one program, both live TV and recorded TV would stop, skip, and stutter every few seconds. Audio would break up.
Later the recordings were checked and they were fine but they could not be viewed while a recoding was in process on that drive. A file from a different drive would play OK.
I switched back to a 1TB drive and had no problem. I could record 4 HD programs while watching any one of them or while watching a different program on the drive.
I then did the same experiment on the backup system. Recording 4 HD programs to the 2TB drive while watching one of them or a different file on the same 2TB drive and everything was fine. No issues.
I ran the WD diagnostics on the "bad" 2TB drive in the main system and it reported no problems.
I defrag the drives weekly and checked the bad 2TB drive just after defragging. Just as bad. All recorded TV drives are formated for 64K clusters.
Lastly all 8 of the RTV drives in the two systems are WD GP drives but they are not all the exact same model. EARS, EADS, etc.
The backup PC is a bit more powerful but since the main mc pc works as well on the 1TB drives, I don't think it's a CPU problem.
Do I have a bad drive? It would be a bit of hassle but I could swap the two 2TB drives and see if the problem stays with the drive or with the system.
Any other suggestions? Better drive diagnostic software, for example?
