Hi everyone.
i've currently got a Kaypro 4 on the bench which seems to be a little un co operative when starting from cold. When I insert the boot disk, the A drive is spinning. Most of the time I will just hear the read/write head trying to read track 0. Other times i'll hear no head movement at all. After a few minutes of letting the drive spin it will read okay.
I was thinking this might be a dirty head / lubrication issue. Especially since the fault is only present when the drive has not been used for a number of hours.
Any second opinions on this? Also what's the best type of silicon grease to use on the drive rails (I havent actually worked on many 5.25" drives before). I'm also assuming that i can use some sewing machine oil on the disk-spin and stepper motors (if I am able to get access to them).
Thanks!
