[PD] readsf~ harddisc access

[Johannes Burström]

Hi list

I have some questions about readsf~. Recently i have had some trouble 
with my audio getting all cracked up, forcing me to restart pd to get 
everything to work again. I've always blamed winxp and my audiophile usb 
soundcard for everything, but today I experienced it again,  with a very 
simple patch - just a rather large soundfile played back by readsf~ fed 
into a munger~. After a sound breakdown with pd cpu usage spiking up to 
97%+ i decided to defragment my drive, after which everything  went as 
it should, and still is. so i have a few questions:

Does this (harddisc access problems = total audio breakdown) make any 
sense, or is it just a coincidence? after playing some live gigs with 
pd, i'm starting to believe in fairies and ghosts.

Could i set the buffer size argument in readsf~ in any way to prevent 
this from happening, even from a not-so-tidy hard drive?

The help file for readsf~ tells me to wait "a few seconds" after opening 
a file to start the playback. Is this time related to the buffer size?

Thanks for helping out.
