Wow, Scott, this is exacly what I was thinking about. I just finshed opening up and exploring my SL-C3000, and when I got to the Hitachi 3k6-4, I found it was held in by the tiniest, and oddest set of screws I have ever seen.
How did you get the drive off?
As far as that goes, there are several different candidates for me to consider for replacing the 3K6-4. Obviously, the 3K6-6, but the Seagate 68022 comes to mind, and man, it's 8Gb!
Thinking about that, what kind of interface is on the 3K6-4? Is it CF? That would be Great, it would make it a drop in compatible (I think/hope) with the Seaget ST68022CF, and seeing as I cant't see that those folks are even selling the ATA version, well, what kind of interace is on the 3K6-4, you were saying? (no, I'm not out of control, yet).
And, it it should take me long enough to get the correct screwdriver, there is (in the near future) the Seagate ST612712 (it's their ST1.3 model line). It's spec'ed at just slightly smaller, slightly lower powered, slightly faster, and (gulp) 12 Gb! It's supposed to be available 3q06.
OK, your turn.
