Anyhoo, the original post says you replaced the floppy drive with a
*brand new* unit. I presume then that it is a PowerMac floppy disk drive
right? In which case you run into an itty bitty problem or two. There
are two Mac floppy drive types ya see, the original (subtle, thin,
graceful slot - like the IIci or the SE/30 for example) is the
'auto-inject' mechanism. This sucks the disk in after it passes the
halfway point of insertion and is a very clever mechanical design, sadly
prone to infestation by dust bunnies. The other is the type used on late
68ks (Q8x0, LC475 etc.) and PowerMac machines. This is 'manual inject'
and does not make any attempts to take the disk in by itself, you
practically have to cram the disk down it's throat before it drops into
the drive, hence the huge ugly oval hole and gaping great big slot to
get your fingers into. The crux of the problem is that, in usual
circumstances, certainly in the LCs and the SEs, the two are not
interchangeable due to slight physical difference in slot height. This
means a new drive in an old Mac will suffer the problems you describe
with drag 'cause the slots don't line up with each other properly on the
case and the drive. Hey presto ;). You need to find another old auto
inject drive, try LEM Swap.
