I finally got my ebay set of 5 packs, they came directly from Amazon, and indeed, somehow the USPS had delivered to some incorrect address, it had my last name in huge letters written in sharpie by the time I got it.
Does anyone know part numbers for the drive screw/label packs for larger JBODs like the 45-bay 847 or the 88-bay 2.5" 417? Only one of my 45-bay JBODs actually has trays numbered sequentially from 0-44 and the 24-bay packs are all I ever find for sale separately.
I consider it a bonus that the 3.5" dummy drives are installed with two proper drive screws. For 2.5" trays, the blanks are held in with 4x super-coarse thread screws which only work for holding the blanks in. Fortunately I already have enough 2.5" drive screws for all of my trays, but if a deal like this shows up for the 2.5" screws, I'll probably pick up a few packs to be safe.
There is nothing more annoying than finally having the time to work on something and realizing you are short some small part like these screws!
