I am having a strange problem with my PC. I have 2 hard drives of WD ,One is 1 TB and other is 2 TB capacity. I have installed Debian 6 in 1 TB hard drive from live DVD. Before it I was using Ubuntu 10.10, the same problem was their in Ubuntu too.
Whenever I download new files in 1 TB hard drive or copy files into it or from it then they got corrupted. When files are in 2 TB hard disk then they show the correct checksum but after copying into 1 TB their checksum changes and when I try to write them in DVD the DVD shows error when played.
I have to install Windows to download Debian live DVD and then from windows I burnt it onto DVD. Then after installing Debian I copied that ISO file of debian onto 1 TB hard disk then it shows different SHA1/md5 checksum. I use the virtual box to install it virtually and it is not installing and shows error.
Is their any problem in software or in the hard disk.
