Well, I just upgraded from 7.10 to 8.04, and I was shocked when I noticed how long it took to boot... I did some research on my own and I think I might know what the problem is. When my Kubuntu tries to boot, it writes things like these on screen (I deactivated de splash screen):
ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
ata6.00: cmd c4/00:08:00:00:00/00:00:00:00:00/e0 tag 0 pio 4096 in
ata6.00: status: {DRDY}
ata6.00: revalidation failed (errno=-5)
ata6.00: SRST failed (errno=-16)
It repeats some of these lines many times... Well, doing some research, I came to the conclusion that my Kubuntu for some reason thinks I have two Hard Drives... What makes me think this? 3 things:
1. When I go to System Settings >> Advanced >> Disk & FIlesystems, I see my actual HD (with all my partitions), and a second drive, called "Disk Config Disk"
2. In my /dev/ directory I see sda, sda1, sda2, sda3, sda5, sda6 and sdb... What's that sdb doing there!?
3. If I do "sudo lshw" I find:
*-disk:0 (with all its things)
*-disk:1
description: SCSI Disk
physical id: 1
bus info: scsi@5:0.0.0
logical name: /dev/sdb
size: 320KiB (327KB)
What is that disk 1
Well, I believe my kubuntu tries to boot at sdb first... So, I would like to know two things:
1. How can I make it boot on sda?
2. How can I make sdb dissapear?
That's it. I hope I made some sense (I don't know too much about these things, so maybe I just made all this up, lol...). Thanks in advance.
