View Full Version : [ubuntu] Grub Error 18 after one month

May 4th, 2008, 11:07 PM
I got this laptop one month ago (Gateway MT6728), removed Vista, installed Ubuntu, and no real problems until today when I got some I/O errors randomly. Now I get this when I boot:

GRUB Loading stage1.5.

GRUB loading, please wait...
Error 18

The error shows up after about a minute and it sounds like the hard drive is struggling a bit. I booted a GParted LiveCD, and it stalls here for about a minute:

* udev loading module i2c_i801 [ !! ]

It drops to the console after Xorg fails to boot and I get this message every 5 seconds or so:

ata1.00: exception Emask 0x0 SAct 0x3 SErr 0x0 action 0x0
ata1.00: (irq_stat 0x40000008)

sd 2:0:0:0: [sda] Write Protect is off
sd 2:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA

...and occassionally this:

Buffer I/O error on device sda1, logical block 0
(..) block 1
(..) block 2

So is my hard drive dead or do I need to fiddle with GRUB to get it working again?

Look you can download supergrub and burn it on a cd , use as a boot cd then get in and find the option where it says "restore grub to MBR" .
i think you can reach it by entering to the option "Grub & Linux" .

Wow, thanks for the fast reply. Just curious -- will this require reinstallation or wipe my partition in any way?

Well, I downloaded supergrub and selected "Restore GRUB to Hard Drive (MBR)", and it does this:

Booting 'trying /grub/stage1 /boot/grub/stage1'

selectfile /grub/stage1 /boot/grub/stage1

Then a loooong wait, maybe 5 minutes or so...

Error 15: File not found
Bootng 'not lucky'

pause SGD has NOT succeeded :(
SGD has NOT succeeded :(

Any thoughts?

Bump. Time to get a new drive?

Maybe you need a new disk. Did you check GRUBs website for info on error 18? I happened to see something about it while looking up splash screen image how-tos.

Looks like I just need a new drive. Shocking that this would happen one month after purchase, but I guess that's the price I pay for a Gateway laptop. And of course wiping Vista and installing Ubuntu voided my warranty (assuming I had any to begin with).

Thanks for the support!

If Gateway won't replace your HD, try the manufacturer of the drive.

It's worth a shot.
