[HECnet] What started the modern VAX drive limit myth?

[Ian McLaughlin]

There we go - found it:

But it's on the 3100.   The 4000 seems to be okay.

I seem to recall reading somewhere (but I'm unable to find the reference at the moment) that there was some event that caused a problem.   Something like a system crash or bugcheck, which causes a ROM routine to be called which will dump RAM to disk for later analysis.   The problem is that the ROM routine has a maximum size issue, and it may wrap around and overwrite a lower section of the hard drive.

I really wish I could find the reference, though...

Afternoon all,

What started that myth?   I've managed to get a 146G drive working in a VAXstation 4000/60 (10,000 RPM, too!).   Unless I did my maths wrong, it's showing up as 136G as a FILES-11 volume(~700M in SHOW DEVICES at the tripel chevron prompt)

There also seems to be no 1G boot drive limit on this as my boot drive is about 4G.

Was this a limit that existed in earlier VAXstations?
