Multiple disks (different sizes) and Squid cache

I mailed this before, but unfortunately i didn't get very much response
(only 1 mail from Mr. Bekker, but he didn't knew a solution either).
So i'm mailing it again, hoping that some one can help me a little.

I plugged in two extra harddisks in our Sun Sparc 470 running Squid. 
Now i was wondering (in the light of a message earlier this week on this
The old cache is on one disk:
       1. c1t1d0 <CDC IPI 9722 cyl 1630 alt 1 hd 7 sec 156>
And now i have two new ones, with different sizes:
       2. c0t1d0 <CDC-94181-15-0293 cyl 1529 alt 2 hd 15 sec 52>
       3. c0t3d0 <CDC-94181-15-7966 cyl 1503 alt 2 hd 15 sec 52>
No.1 is a disk of 869 mb (of which 750 is cache), while no. 2 and 3 are
550 mb. (1 IPI, 2/3 SCSI)
And the question is now: 
'How do i correctly define my squid cache dirs now in the config ?'
Coz, if i specify 
cache_swap 1750 (approx total of the three disks)
cache_dir /squid-cache
cache_dir /squid-cache1	(the places where they are mounted)
cache_dir /squid-cache2
I expect that Squid will divide 1750 by three and thus two disks will
overflow, which of course is impossible. Squid this good that it determines automatically how big each disk
is, and correctly assigns swapspace to each (i.c. 750,550,550).
I read somewhere earlier this week that all cache dirs MUST be the same
Is this correct and who can give me more info on this ?
Maybe Duane himself ?
