Fully-functional? Nope... I think it may have experienced a head crash. Most (but not all) of the disk cannot be written to, and even read operations randomly have errors.
Origin: Macintosh SE FDHD
Current home: The graveyard
The 8425SA was a SCSI version of the popular MFM 8425. I'm not too familiar with anyone aside from Apple building systems with the SCSI version, but I'm sure it happened.
This particular example was pulled from a Macintosh SE FDHD. The drive just refused to properly write one day (though Macintosh System 6 was still booting and running fine), and it was mere minutes later that the file system failed catastrophically. All that remains is a gloriously late-80s metal shell and some of the most unique hard drive sounds to grace the earth.
