I have several of these in their E configuration (i.e. SCA).

Do you mean an unusual tik? If so, it may be broken.

Maybe you're not used to 7200 rpm disks. 45 degrees C is quite hot
(but that is the limit).

That may be a contributing cause of errors, if you need termination
and have got it unset. Three of the jumpers are the SCSI ID in binary,
0 (all open) through 7 (all closed).
There are another three on the bottom, two of which are normally
closed (motor start and parity checking).
There are diagrams available at fujitsu's website; better than my drawing.

That depends what's wrong with it, as it could interfere with the
bus. (BTW if it's not at the end, it won't need termination here.)
Of course, you might try it on its own, as 2GB is big enough for a
test installation. Then you can thrash it to your heart's content.
Do remember not to let the case touch the mounting bracket except
where it's intended (insulated).
