[Solved] invalid partition table on /dev/sda -- wrong signature 0.

Roshan Karki Anonymous
I was trying to use Disk Utility program to edit some partition in my system. But I got a strange error message "invalid partition table on /dev/sda -- wrong signature 0." and couldn't proceed. So I tried with gparted(Gnome Partition Editor). The result wasn't any different.

Today while clean installing Ubuntu 11.10 Oneiric Ocelot, the installer said that there was no partition in my disk. While trying live CD, I could find all the partition and read data.

If you also encounter any of the above problem, simple run fdisk by sudo fdisk /dev/sda press p and then press w. You'll see a message "The partition table has been altered!".

Now try running the partition editor or the installer again.

    For me, it didn't wipe the partition table but rather seemed to recreate it. At least, I didn't need to redefine each partition afterwards, yet it fixed the "wrong signature 0" error I was getting in parted.

Increase Free Space On HTC Desire Android Phones

Roshan Karki Anonymous
Are you running out of free space on phones like HTC Desire and variants? It only has about 150MB of free space and after official Gingerbread 2.3.3 update the free space has decreased. Its really frustrating seeing all those apps with 20MB+ size eating up valuable space on Android phones. Even with App2SD I had very very difficult time maintaining free space. Installing apps like Facebook, Google Plus, Google Reader would eat up all the space. Today I used link2sd to increase free space on my Android phone and now I've more than 1GB of free space for installing apps. I've been installed so so many apps now. link2sd can move your application apk, dex and lib files to second partition of your SD card and creates a symlink where necessary. Even when you mount your SD card in computer the apps in SD card will work as only the first partition will be mounted in computer.
