VTOC or Volume Table of Contents refers to the data structure, without which no data set (a file with record organization) residing on a UNIX disk volume can be located. This is the repository of all information about the data set such as their name, location, permissions and size. If a particular data set is needed to be searched in a UNIX volume, VTOC is referred. It will give the location information about the data set and then it will be is accessed.
This data structure resides on the first 64K tracks of the volume and is the mandatory component to access a file from a volume. Its corruption signifies that there is no mean through which UNIX operating system can locate the file and hence let you access it. The corruption can result from virus attack, use of some unsafe commands or unexpected shutdown.
VTOC corruption is really a critical condition of data loss and needs UNIX recovery as the cure. When there is no reference of the residing data, no usual mean can succeed to get access of it, but the suitable UNIX data recovery software can do the job effectively.
Stellar offers high-ending UNIX recovery products for major distributions of UNIX, which skillfully recover the lost data via efficient scanning algorithms. Data recovery UNIX after VTOC corruption needs precision and hence an extra careful treatment is given to the lost data through read-only conduct and graphically rich interface.
To recover lost data and hence benefit UNIX data recovery, follow the mentioned steps:
