Thread: Hard drive detected only sometimes

-

i'm having issue since i've installed karmic final (amd64). during installation, using desktop install cd, 1 of hard drives being detected sometimes, let's 1 out of 5 tries. proceed installation once detected i'm having same behavior in new installed karmic. let me never happened before, 9.04 installation fine , i've tried jaunty livecd see happens , show both hds every time.
odd i've noticed when start in recovery mode can see both hds always.
problematic hard drive sdb, when not detected palimpsest disk utility can't see it, neither gparted. hd has bad sectors, isolate damage area , not formated (see gap between end of sdb2 ant start of sdb3). never have problem since i've done this. every time boot works fine.

sdb1 has w7
sdb2 has xp
sdb3 storage (ntfs)
sdb4 storage (ext4)

info, fdisk -l (when both detected):

also grub2 menu has both windows installed in sdb , works fine.

i'll stay karmic if can't have both hds i'll forced go jaunty.
