The question I have is regarding the vob files corruption in hard drives. I have a Hitach 200 GB hard drive and partition it into two 100 GB volumes and formatted as NTFS. The problem is when the numbers of the files, all vob files, get into a certain numbers, say 90GB worth of files, approximately between 10-13 movies, the hard drives corruptted and all the stored files are lost and the only way to get the hard drive working again is to re-format. This hard drive contains no operation system and I used it as secondary master. Thank you very much for your help.
