Subject: My Rodime Wont Spin
Well, releasing the brake has allowed the device to spin again, but it makes
the most horrific noise and doesn't seem to come in to a 'ready' state (the
on-board LED stays permanenty lit). I think its ready for the bin.
Thanks for the replies so far on getting the WD filecard formatted. I'm getting
'format error 14' from SuperForm (v1.06) after about 30-45 minutes of formatting
activity.
I remember the drive as being 32Mb, and there are defects listed on heads
0 & 3, so it must have 4 heads. How do I go about changing the spt value
in superform? I only get options for heads, cylinders, step rate, rwcc and lz.
Thanks again,
Julian.
