Quick Guide to Data Recovery for Linux, Novell and Unix

Guide to data recovery for different operating systems

Linux OS

Linux is one of the most affordable and popular operating systems (OS) belonging to the umbrella of UNIX OS. Technical users favour it over other OS as it is known for its performance, flexibility and stability. Within it, variants like Turbo Linux, RedHat Linux, Mandrake Linux, amongst others, prove to be preferred by a growing base of tech-savvy consumers. Linux can adopt files such as ext3fs, JFS, ReiserFS and ext2fs.

Possible problems laptop and desktop users may encounter include hard disk crashes, un-mountable volume, damaged LVM logical volume and critical errors that affect the ability to perform the fsck check. In Singapore, many consumers seeking data recovery for their Linux OS do so because of damaged or corrupted hard disk. It is not recommended for users to run fsck or commercial utility as it can cause further problems to the file system, complicating any recovery effort.

Novell OS

In the erstwhile data server market, Novell, a file server operating system for sharing of various data files, was the leading OS. Today, some consumers stay loyal, with many still using Netware 2.x to Netware 6.x on Novell Netware on Traditional File System (NWFS), Novel Storage System (NSS) and net386. This base of consumers may experience problems like damaged un-mountable Novell volume; missing volume tables and critical system information; and inability of SYS volume in booting up, among others.


UNIX OS is a name associated with hundreds of Unix-like OSs, which are supported by many companies and organisations. UNIX OS is a central set of commands, with each variant tuning the commands in unique ways to meet different needs and specifications. As a result, each UNIX possesses diverse features and capabilities developed for compatibility with various hardware sets. Popular UNIX OS includes variants such as Apple MacOS X Server, LynxOS by Lynx Real-Time Systems and Irix by Silicon Graphics. Solaris, HP-UX and AIX are examples of commercial products that distribute UNIX variants. Free-for-use UNIXs are available too, ranging from Open BSD to Free BSD, and even other Linux variants. A network of helpful individuals and not-for-profit organisations are involved in the distribution and promotion of such free variants, which are allowed under the GNU General Public License. This license is a free software license that authorises the use, sharing and modification of the software in question. In other words, users can modify and share these free variants to the parameter defined by this license.
