Topic: Attemp to resize and move a partition fails

Dear,

I have basically two partitions: one windows partition and one linux partition (the other partitions). Because the first lacks space, and it is just a fresh install I was trying to shrink the linux partition (with pain in my heart) to 100GB, then move it further on the disc so that the space after my linux partition would be before it thereby able to extend the windows partition with the free unallocated space.

However, it fails with an error.

In short the operations applied are:
1) Move /dev/sda3 to the right and shrink it from 99.98 GiB to 99.98 GiB  00:35:13    ( ERROR )
2) Grow /dev/sda2 from 19.66 GiB to 43.11 GiB

I hope someone can help me because I can't delete the windows partition (I just installed my licensed TI-Nspired software needed for my university, and it is limited to two installs :s)

Thank you so far!

Re: Attemp to resize and move a partition fails

First the good news.  Since the error occurred when GParted was only reading (not moving or copying) the partition, all data should still be intact.

Now the bad news.  The following error

Error while reading block at sector 124737536

indicates a hardware problem.  This can be caused by a loose drive connection cable, or more often is due to a failing hard drive.

Drive manufacturers often provide drive testing software at their web sites.  Please note that this software often overwrites the drive so be sure to backup your data before running drive tests.

On another note, version 0.7.0 of GParted is quite old.  We highly recommend that you use the latest version (currently 0.9.1) which is also available as a bootable image (GParted-Live).

Re: Attemp to resize and move a partition fails

Thank you for the fast reply! A backup has been updated.

By now I have checked the connection of my drive which visually seems still good (it is a laptop). Based on your recommendation I searched for a testing program.

1) When reading out the SMART information everything is labeled 'healthy'.
2) I have also ran badblocks with the following output:

user@pc:~$ sudo badblocks -sv -b 512 /dev/sda
[sudo] password for user: 
Checking blocks 0 to 312581807
Checking for bad blocks (read-only test): 124740672one, 30:09 elapsed
124740688one, 31:03 elapsed
124740689one, 31:20 elapsed

124740695one, 33:10 elapsed
done                                
Pass completed, 9 bad blocks found.

3) I have read (http://askubuntu.com/questions/21101/ho … sector-xxx) that you can run this command to mark de bad sectors as 'bad':

sudo dd if=<device-name> of=/dev/null bs=512 count=1 skip=<sector>

I am wondering if this command is safe to run? I mean obviously I will lose the data in that sector and should check regulary the drive to see if it isn't failing. But will it mark the sectors as 'bad' so they won't be used anymore by the system?

PS: downloaded the new gparted version, much more handy and fast live cd! Great work!

Re: Attemp to resize and move a partition fails

From reading the link you provided, it would appear that the user psusi suggests you use hdparm with some parameters to address the bad blocks.

I had to eventually reformat the whole drive. Because I needed a windows partition for some only windows programs for my university - such a pity -. The tool provided by my HD manufacturer (WD)  was only Windows based and could only handle the active windows partition.

Thank you for the help!
