I needed to clone my disk to another hard drive .
I did it as the following :
#dd if=/dev/sdb of=/dev/sdc
But after a while, the procedure ended with the "writing to /dev/sdc
input/output error" message.
Can you please let me know how can I overcome this as the fdisk now returns as "
#fdisk /dev/sdc
"I do not know how to handle files with mode 81a4
must set cylinders"
What can I do at know ?
It's helpful to start with a paragraph that explains "why", and follow
that with paragraph(s) that explain "what".
It's best to cut and paste the relevant portions of the console session
into the body of your post, rather than chopping it up and mixing the
pieces with prose. For example:
2013-11-11 12:19:59 dpchrist@p43200 ~
$ grep PS1 .bash_profile
export PS1='\n\D{%Y-%m-%d %H:%M:%S} \u@\h \w\n\$ '
Notes:
1. The console session is preceded by a blank line, indented, and
followed by a blank line so that it stands out clearly.
2. I have set my shell prompt to show the date, time, username,
hostname, and current working directory. This is useful information for
me, and especially for people trying to help me.
3. People can see the exact command I invoked.
4. People can see the exact output of that command.
In the meantime, if I want to format the target hard disk to have a
fresh disk , can you please let me know how to do that ?
I use the 'dd' command and special device '/dev/zero' to fill drives
with zeros:
2013-11-11 12:23:29 dpchrist@p43200 ~/sandbox/debian
$ dd if=/dev/zero of=zero.bin bs=1M count=1
1+0 records in
1+0 records out
1048576 bytes (1.0 MB) copied, 0.00526288 s, 199 MB/s
2013-11-11 12:23:46 dpchrist@p43200 ~/sandbox/debian
$ ll zero.bin
-rw-r--r-- 1 dpchrist dpchrist 1048576 2013/11/11 12:23:46 zero.bin
HTH,
David
