Lets rectify error : “DISK READ ERROR OCCURED”

It happens some times that at the time of up gradation the hard drive is automatically formatted with FAT (File Allocation Table) file system and all the data stored on the hard drive gets lost.

This situation is general in dual-boot system. This behavior of Microsoft Windows makes all your data inaccessible and can cause serious data loss. Now you are required to scan the affected hard drive and opt for an effective Windows Data Recovery to retrieve lost data from Windows hard drive.

In a practical situation, if you've NT-based version of Microsoft Windows installed on first primary partition that is formatted as NTFS (New Technology File System), and you select to format the partition as NTFS file system during setup to begin with clean partition, Windows setup process will format the drive as FAT, copy files from CD and try to reboot system in GUI mode to continue installation. In such situations, your system would stop responding and you come across below error message:

“DISK READ ERROR occurred.”

If you run ChkDsk on affected Windows drive, you will encounter following error message:

“The media descriptor byte is invalid.
FAT copies are not the same.
Many cross linked files.
All directory entries were invalid.”

Try to repair partition doesn't sort out the problem and the installation could not be continued. In these cases, you need to find out the cause of this problem and carry out Windows Recovery by fixing it.

Root of the problem

Earlier Windows NT kernel format the partition using FAT file system and then convert the file system to NTFS on final re-boot after installation. If you reformat the boot partition using NTFS file system, setup writes 16 sector boot area on freshly formatted FAT drive after file copy operation completes.

In order to sort out such issue, Windows Data Recovery is required. This is best possible using advanced third-party applications, known as Windows Data Recovery Software. The tools work in the majority of data loss situations and allow you to perform quick and easy recovery. The have non-destructive conduct and thus do not alter original data on drive and always perform safe recovery.
