Journal Journal: when sfdisk complains about GPT use sgdisk for RAID disk replacement 3
sgdisk --backup=table
sgdisk --load-backup=table
sgdisk -G
sgdisk --backup=table
sgdisk --load-backup=table
sgdisk -G
use http://ahkscript.org/download/ - just download, install and run - you will get the menu where you can chose to open a sample script.
Replace it's content with this
SetCapsLockState, AlwaysOff
+CapsLock::CapsLock
CapsLock::Send, {CTRLDOWN}{SHIFTDOWN}{SHIFTUP}{CTRLUP}{CTRLUP}
return
this will make CapsLock to send Shift+Ctrl sequence.
Now go to the the "control panel"->"region and language"->"keyboards and languages"->"change keyboards"->"advanced key settings"->"change key sequence between input languages"->"switch keyboard layout". Chose Shift+Ctrl there. It should work now!
# mdadm --manage
# mdadm --manage
Past that point, its just a matter of powering off and replacing the drive at your earliest convenience. Once you got a new drive, pop it in, boot the system up, clone the partition table, and add the new partition to the array:
# sfdisk -d
# mdadm --manage

complains about lacking disk space. Here is the remedy:
sudo
You have to follow the same procedure in the file
97-bluetooth-hid2hci.rules
Command:
sudo gedit
Here is a sum up:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \ RUN+="hid2hci --method=logitech-hid --devpath=%p"
AFTER
KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \ RUN+="hid2hci --method=logitech-hid --devpath=%p"
Just change the word hiddev with hidraw.
That's it! Don't forget to reboot the PC and synchronize both peripherals pressing the bouton connect of each device.
This card's driver is in the blacklist and so it does not get loaded. The card itself is not visible then with lspci.
sudo vi
and comment out the line with "blacklist prism54"
The card will be available after a reboot.

Create FAT partition with Disc Utility from Gnome and formate with mkfs.vfat (fat32)
Reboot into the mode 3 in FreeDOS (wait until system asks you, it can take a few seconds) and with C: you will get to the utility.
Disabling of the timer
It was not easy to find a eSATA PCIe card that is reported as compartible with Ubuntu Intrepid LInux. DeLock Nr 89143 with the chipset JMB363 JMicron 20360/20363 AHCI Controller (rev 03) works just fine out of the box. Just do not forget to configure the jumpers on the card to be able to use external eSATA ports. Also make sure you unmount the discs before disconnecting them. Otherwise you will have to run fsck in the best case.

Make sure if you add it it is to the "mount" line. The line numbers are likely different with your system. You might start with 10 instead of 5, seconds delay.

known bug in Intrepid has no influence on the creation of the array.
to check the SMART status of the drives do this
for letter in a b c d e f; do echo "############## Below the information for the drive
/dev/sd$letter ##########" && sudo smartctl -H -l error /dev/sd$letter ; done
add internal bitmap to reduce rebuild time
sudo mdadm --grow --bitmap=internal
/dev/md0
better still add external bitmap to speed up the write speed to compared to internal bitmap
sudo mdadm --grow --bitmap=none
/dev/md0 #remove bitmap sudo mdadm -G /dev/md0 -b /media/persistent_temp/md0_intent_var # my /var is mounted into ramdisk

for letter in a b c d e ; do echo "Drive

Turn of APM and spin down. Set sound management to "fast". APM is not supported on my WD drives.
for letter in a b c d e ; do echo "Drive

If you do something right once, someone will ask you to do it again.
