Disable Windows has detected a hard disk problem message in windows

The following are the steps to disable the error message associated with a bad hard drive, the message that windows will display after every login, we will disable it from within windows without disabling it in the BIOS.

The message above reads (On my computer, on yours, the disk model number and the names of the volumes will probably be different.

Windows has detected a hard disk problem.
Back up your files immediately to prevent information loss, and then contact the computer manufacturer to determine if you need to repair or replace the disk

Then, you are presented with the following two options

Start the backup process

Ask me again later
-- If the disk fails before the next warning, you could lose all of the programs and documents on the disk.

In the show details dialogue you should see 

Immediate steps
Because disk failure will cause you to loose all programs, files and documents on the disk, you should back up your important information immediately, try not to use your computer until you have repaired or replaced the hard disk.
Which disk is failing
The following hard disks are reporting failure.
Disk name: TOSHIBA MK3264GSXN ATA Device
Volume: C:, D:, E: 

My advice would be

Do not disable S.M.A.R.T. from BIOS, rather, ask windows not to display this message, this is because for a failing disk, you would want the S.M.A.R.T. data accessible from other programs or to keep an eye on it.

To disable this error message from within windows, do the following

click the start button and enter the word “task” in the search box, Task Scheduler should appear, right click it and chose run as administrator.
Once it is open, follow the tree to your left as follows
“Task Scheduler Library” => “Microsoft” => “Windows”. => “DiskDiagnostic”

As shown in the image, select the second entry, right click it, then click disable.

The following is the dialogue

close, and restart your computer to check if it worked.

The Linux DD command

To detect the progress or how far dd has come in a running copy, open a second terminal window, run top to get the id of the dd process, then issue the command kill -USR1 xxxx (replace xxx with the actual ID of the process), now it may appear that nothing happened, but swicth the terminal to the one dd is running in

you should see something like

1036902161+0 records in
1036902160+0 records out
530893905920 bytes (531 GB) copied, 29702.1 s, 17.9 MB/s

Recovering files from ext4 partition

Update, although extundelete restrored most of my files, some files could only be restored with no file name through an application that is installed with testdisk called photorec

So, i added a directory to eclypse, a message apears, i hit enter axcidentally, all the files in the web directory are lost, no backup, years of programming…

Instantly, i shut down the computer so that i do not overwrite the disk space with new files and logs and the like, i got a larger disk (1.5tb) and did the DD first (i recommend gddrescue in place of DD just in case your disk has bad sectors).

Installed Linux (Debian 7) on the new disk, installed the hard drive from the other computer to the new PC, then installed the software i always use to recover files, testdisk, test disk did not work as expected, on both disks, when it comes to the ext4 partition, the process that ended in an error would be as follows

create log file
Chose the 1TB disk (the one with the deleted files
Partition type (INTEL)
Chose the main partition *(ext4) and chose List (left and right arrow keys)
Damn, the error.

TestDisk 6.13, Data Recovery Utility, November 2011

Can't open filesystem. Filesystem seems damaged.

So, i quit TestDisk and installed
apt-get install extundelete

extundelete /dev/sdb1 --restore-directory /var/www

This way, i only restore the files from that direcotry, if you want all the deleted files, you could surely use something like

extundelete /dev/sda4 --restore-all

Anyway, my files are back, a few are missing, but i am sure i can deal with that

MySQL – Can’t change ownership of the file Errcode: 1

When trying to repair tables (or optimise), there seems to be an error that is giving me a hard time.

The SQL statement REPAIR TABLE mytablename; returns the following

| Table               | Op     | Msg_type | Msg_text                                                                                     |
| mydbase.mytablename | repair | error    | 1 when fixing table                                                                          |
| mydbase.mytablename | repair | Error    | Can't change ownership of the file '/hds/wd1tb_2/mysql/mydbase/mytablename.MYD' (Errcode: 1) |
| mydbase.mytablename | repair | status   | Operation failed                                                                             |

So, the only solution up to now is to

chmod -R 700 /hds/wd1tb_2/mysql/
chown -R mysql:mysql /hds/wd1tb_2/mysql/

This error has already been reported as a big long time ago, but it seems to be still there, this is the only way around the situation, and it does not seem to have been resolved with MySQL 5.5.33-0+wheezy1
