dd blank HD fail

Hi all.

Running Ubuntu 12.04 on USB

# dd if=/dev/zero of=/dev/sda

Code:

dd: writing to `/dev/sda': Input/output error 281+0 records in 280+0 records out 143360 bytes (143 kB) copied, 77.3732 s, 1.9 kB/s

# dd if=/dev/zero of=/dev/sda bs=512

Code:

dd: writing `/dev/sda': Input/output error 281+0 records in 280+0 records out 143360 bytes (143 kB) copied, 26.7369 s, 5.4 kB/s 281+0 records in 280+0 records out 143360 bytes (143 kB) copied, 26.737 s, 5.4 kB/s

Is the HD corrupted? Please help

TIA

Can you run following commands and post its output there?

Code:

blkid

Code:

file /dev/sda

And also run with strace

Code:

strace -e trace=all dd if=/dev/zero of=/dev/sda

Hi,

Before reading your posting I succeeded installing Ubuntu 12.04 on the HD. But I couldn't boot it.

On reboot, it dropped to;
BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built=in shell (sah)
Enter 'help' for a list of built-in commands

(initramfs)

Reboot and started Recovery Mode;
..........
sd 1:0:0:0 [sda] Add. Sense: Unrecovered read error - auto real locate failed
sd 1:0:0:0 [sde] CDN: Read(10) :28 00 00 00 01 18 00 00 08 00
end_request: I/O error, dev sda, sector 285
Buffer I/O error on devcice sda, logical block 35
ata2: EH complete

(hanging here)

It is very strange. Now I even can't boot Live Ubuntu 12.04 USB. It just hangs on Ubuntu screen. But I can boot Live Fedora17 USB

I'm prepared running gparted to partition the HD to check.

As you booted using Live Fedora-17 cd - Can you try and run fsck on /dev/sda1 ? so that any bad blocks will detected and added to bad block list. I assume sda1 is your Ubuntu partition

That's really strange error message from fsck!

Can you run file -s /dev/sda1 ? For example, I got below output as expected on ext4

If your output(file -s /dev/sda1) doesn't show ext4 ,are you okay to reformat the disk with ext4?

Code:

mkfs.ext4 /dev/sda1

It is quite strange. I'm neither running any program on /dev/sda nor doing any work on it

Can you shutdown and restart the system ? seems like /dev/sda1 is not completely written into MBR records or something ? I'm not sure :shock: Then login to live-cd and try "blkid" to ensure that /dev/sda1 is there and then run fsck.ext4 on it ? Btw,is that external hard-disk or built-in disk?

The HD is now workign again. I won't use it for production but for testing purpose only

Thanks for your help.
