It runs real hot. Not a great drive compared the Quantum d540 (31mb)
that is voicecoil(fast), reliable and known to be very unfussy about
handling. Also the ST251 was very flakey compared to it's 20mb
counterpart the st225. Not all were touchy WRT to handling. The biggest
problems is that between new developments and company turnovers some
really poor drives made it out the door due to design errors or worse
poor quality control.
I still use st506, st412 and st225s but NOT st251s. I also have some 7
Quantum D540s that refuse to die in my PDP-11s, vax, and CP/M systems.
There are billions of working (and cheap) 251 and 251-1 drives out there
though, hence they get used in these applications more than the lesser
available Quantums. You're darn right on the heat too!
