Yeah, the disks are understandable, and many of the rest are not really broken parts but rather attempts by NTAP to troubleshoot a particular problem (hardware, software, or external). I find the power supply and fan assembly problems to be very bizarre, and guess you are either cursed or don't have the controlled enviornment you think you have.
As to the EOL issues, I agree; NTAP should not EOL products as quickly as they do. I would like to see 4+ years going forward. Of course, as a shareholder, I realize this will cut into earnings.
