In a Linux computer, partition table and superblock are two most important data structures. The superblock keeps record of the file system characteristics including its size, empty and filled block, location and size of Inode tables, block size and status. The partition tables stores all required information about hard drive primary partitions.
I'm not sure how to explain this in the subject better, so the "question" may not be right. But here goes. I have three hard drives. Drive A is a 320GB drive, Drive B is a 80 GB Drive, and Drive C is a 1TB Drive.
I am on Ubuntu 12.04 64-bits
I accidentally deleted a NTFS 255 GB partition from Gparted, and yes it contains LOTS of Important data .
Upon realizing the deletion i haven't yet created any file-system on it . So it still shows Unallocated.
I tried Testdisk , but it shows entire partitions created from the beginning Usages .
This sdb is my secondary drive with Xubuntu and Kubuntu on it.
I plan on moving the data I use for statistical analysis (100-ish Gb) onto an SSD. The data is either sqlite single-file db's, or postgresql-managed data.
Someone did a re-installation of his Operating System of the C: drive using his computer's 'Acer hidden recovery partition' (the alt+f10 procedure). Then he chose 'do not back up personal data (this will wipe the entire C: drive)' during the recovery process and his system was 're-installed'. All of his personal data was in that C: drive.
The following quote is the sad, sad story of a thumb drive with the partition table nuked, as told by a friend of mine:
Quote:
Data was recovered from an XP system by booting with a BartPC CD
and copying onto a USB thumb drive. Nothing unusual.
System was rebooted into the XP install CD.
I have installed postgresql via apt-get install postgresql, but have an error, don't make the folder /etc/postgresql/9.1.
The error on psql:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I have installed postgres on f18 x86_64 with the following packages
rpm -qa | grep postgres
postgresql-libs-9.2.2-1.fc18.x86_64
postgresql-server-9.2.2-1.fc18.x86_64
postgresql-9.2.2-1.fc18.x86_64
These are the instructions I could find to setup and start postgres
su -
cd /usr/lib64/pgsql
su postgres
$ initdb -D /var/lib/pgsql/data
$ pg_ctl -D /v
Hi,
I'm new to fedora but not completly new to linux.
Now i wanted to copy some folders _from_ my NTFS partitioned drive to a folder in a XFS partitioned on another drive. I marked them and clicked with the mouse and dragged the icons to the folder in the other drive.
Nothing -seeable- happens.
