HP 7906 drive lives again & stuff

After suffering a head crash on my "new" 7906, I decided I REALLY should have taken the time to clean the filter and the blower squirrel cage and air ducts better before using it. That was done, then the drive wouldn't seek past load point. So I swapped all the cards in the drive card cage with a "spares set" and now the drive is working wonderfully again, passing all diags. It is SO nice to not rely on a single 7900 drive anymore! Word to the wise - lesson learned - never skimp on dissassembly/cleanup of an old style 14" drive. Take the time to get every last piece of dust & debris out! Over the next few weeks I will be cleaning, refurbing, and testing all the other 7906 drives I have. Once I get all working that can be made to work... I will have some known working 7906 drives available for trade, as well as some 13037 controller boxes. Might not have spares of the 13037 pca that goes in the host though. If anyone is interested, let me know. Keep in mind these drives are somewhere in the neighborhood of 200 pounds each. I may get my 7905's working too but not sure I want to give those up just yet. Also - the only way I found to clean the squirrel cage blower was to take it out and clean each fan blade by hand and with a toothbrush. The very fine dust that makes it past the secondary filter cakes on these blades and is very hard to scrub off - it's like concrete. Does anyone have any ideas here? I was thinking of soaking the blower in something to loosen the dirt, but it's unfinished metal and might rust. Any thoughts?
