It would also check the degree of fragmentation and I guess later defragment the hard disk, but actually, debugging errors programm is already officially provided by microsoft in windows operating system called dr. watson. so it is my habit that I always keep noting the superficial details about correcting problems from website. and later further research into it. It is absolutely necessary before using a computer that one must have an idea what mechanisms are involved on installation of programs and storage of other readable/editable data. while I was installing windows xp software, my 10 GB hard disk each time was showing 7 GB, I was not becoming able to format it so that I could have two partitions, i tried my level best then inserted bootable CD of SP3 pack, which helped me format the disk but set up could not copy files to hard disk, I removed it and once again used windows xp CD, and this time because of use of SP3 CD, it created two partitions and I proceeded with installation. Now in case if I have to write some tutorial literature on installation of operating system fromm CD, I would begin as follows, 01- Do You want to completely erase all data on your hard disk, if you are not interested in backing up your files, and want to create new partitions. 02- in the above case, if you want to bring your hard disk into basic partition, and your already installed software is not working, so kindly take the following steps, now mr. brenton this is how my philosophy of work is, because I encountered such problem when my already installed software disappeared, and computer screen was showing only the green lanscape of windows xp and all icons had disappeared. So looking for correct literature on websites has remained my hobby, hoping you will agree.

This is a low level system of the hard drive which will detect mechanical issues and report them to the IDE Bus. When you query the S.M.A.R.T. in a program, you will learn if a hard disk is bad. Can you from Windows detect if a hard drive is bad? – not always. If you write code to have the mechanical arm read the high and low sectors (outermost and innermost sectors), upon failure of the mechanical arm, it will knock and only read the sectors as far as it can extend. While for all practical purposes data is returned (and might look as a success), it might be the wrong data.

I found your literature very important in understanding the work of hard disk. Just recently i downloaded a one click hard disk maintenance software, which could tell after analysis of hard disk, that wether hard disk have any structural defects . I do not know what can be structural defects, except bad blocks on coated platters, but is there any software which could detect mechanical system faults, such as moving of mechanical arm. referring to such an analysis report of a software program, Can I ask, wether such a software can detect any abnormality in mechanical arm, if it is jammed or not moving freely between tracks. I have decided to get a thrown away hard disk, and will open its case, and see wether any servicing to platters and mechanical arm can revive the hard disk. I am munsif ali from pakistan.
