I have several Tandon TM-100 2A (360k, DSDD) drives I have acquired as part of systems or from eBay. After cleaning the castings, heads and rails I usually hook them up to a SuperCard Pro and check rotational speed and variance and step them out to maximum track. Most times they report they can step to track 43 or so.
Two I have tested recently reported (via the SCP software dialog) that they stepped out to track 44 and then the count immediately jumped to 80, briefly. The maximum track reported by the SCP was 79 in both cases.
I did some research on these drives and found an article that suggested the clamp on the stepper motor spindle might be loose, but after tightening the same problem exhibited. Has anyone seen this occur or have an idea why it may be happening? I posted this on the CBMSTUFF forum; they don't think the problem was with the SCP.
If I never attempt to go beyond track 39 or 40 would it be likely to make a difference? In other words, can I ignore this?
Thanks for your replies.
