Ron, I have had a filter on the intake fan of my mid-tower computer case for years. The problem seems to be the little "flip dowd door" on my "D:" slot had broken (several years go) which caused crud to build up on the connectors in the rack. That is why I bought new racks a while ago but since repeatedly inserting and removing the disk drawer was working for me )indert, remove, repeat twice more, then insert and proceed to clone) I failed to get properly motivated to install them. This failure was that no matter how many times I inserted the drawer it still would not get reliable.
I am well aware of infant mortality, when I was still working (Silicon Valley, 1975 till 1992) I would insist on running any product I was involved with at elevated temperatures for 48 hours (burn-in). At Trimble Navigation this reduced our recividism problems in the service department from nearly 40% to only 2 units in the 2 years I was repairing boards, That was way below 1%. Maybe some of that was due to my debugging skills,but the burn-in regime certainly contributed it's share as well. My problem with SATA and SCSI drives is that I have a very happy system of cloning my ATAdrives without needing to change disk drive jumpers, a function I simply am unable to do with my blindness and only one useful (the left one) hand. I still have my three older 120 Gbyte Western Digital hard drives and I think they still work just fine. he real problem was the tray and rack connectors were just coated with too much crud. Maybe I'll buy some new drawers and see how they work in the new racks. Heck, who ever had too many working hard drives?
