Hangup with slackware install

Well after it locates and detects all the sectors, heads, etc. on my main drive (C it hangs up (im guessing trying to read the other 2 HDD's (kinda older bigfoot drives, one 11.9 gigs and the other 19.1 gigs). Well I can't really get farther than this with the install... hung up 3 times this same way, any help?

Oh yea, spex:

Pentium III 550mhz
Current OS - WinXp
512 mb sdram
WD 20 gig (main drive)
BigFoot 11.9 (secondary)
BigFoot 19.1 (secondary)


hmm i dunno if u need more than that... thnx in advance

so unplug the drives, install it - and try adding them then.. this will tell you if its the problem - although I have used soem bigfoots before - just never that large...
