Backup restore fail

Hi,
I am trying to restore database (25 GB) and getting
following error
The backup data in 'F:\BACKUP\ABC.BAK' is incorrectly
formatted. Backups cannot be appended, but existing backup
sets may still be usable.
Has any one solution for this ?
Thanks,
ManojHi Manoj,
This error normally occurs when the filemark in the backup device could not
be read.
The various reasons for this error can be,
1. A media failure on the device where the backup is located.
2. A write failure during the creation of the backup. Eg: Network failre
during a network backup
Solution:
This error normally comes if any one of the file in backup set is
problematic. It might be possible to retrieve other backup sets
from the device by specifying the file number
You can use the RESTORE HEADERONLY command to idenfify the backup file list
and use RESTORE DATABASE to restore the specific file.
Sample code
RESTORE HEADERONLY FROM DISK='c:\backup\dbname.bak'
RESTORE DATABASE mydatabase FROM DISK='C:\backup\dbname.bak' WITH FILE =FileNumber
Have a look into this article,

Thanks
