RAID Metadata Error

BIOS RAID Metadata Error

This type of error may be occurred due to if the hard drive previously installed in those systems which configured with hardware RAID and when we use this hard drive in another system that has not hardware RAID so that error may appear and during installation of Linux OS on create partition windows the hard drive latter may be appear like as “/dev/mapper/…”. Until we correct this error, OS cannot install on this hard drive. If may be install Linux OS but cannot boot the OS.

To correct this problem follow the instructions bellow.

First of all attach the error hard drive as secondary with any Linux primary hard drive and boot the system with primary hard drive.

Now open terminal and run the following command on the terminal.

# fdisk   -l                               (To check the details of disk status).

# cat /dev/zero > /dev/sdx    (where sdx is our secondary hard drive letter).

It will repair the all block of hard drive as zero i.e. low level formatting.

This command will take time as depend upon size of hard drive it will take about 1Hr or more than this to take terminal back.

After terminal is getting back turn off the system and unattached the secondary hard drive.

If we want to check the hard drive RAID Metadata problem is solved or not. Attach only this hard drive in the system and boot the system with Linux DVD and check this on were we create partitions during Linux installation. Here should show the hard drive physical path as “/dev/hda” for IDE or “/dev/sad” for SATA/SCSI.
