how a hard disk finds it's zero sector?
82317
After a PC's BIOS eliminates the possibility of a floppy disk boot, control is passed to some code in Memory that comes from the contents of the very first sector of its first physical Hard Disk. The code contained in that sector is most often* that of the OS's MBR (Master Boot Record). This location can be referenced as either Absolute Sector Zero (0) or as CHS 0, 0, 1.\n\nhttp://mirror.href.com/thestarman/asm/mbr/DiskTerms.htm#LOC

Each computer drive -- whether a hard disk, floppy, CD, or even multiple partitions on a single hard drive -- has a drive letter.\n\nMSWindows assigns the letter C to the main hard drive. The next one in line, whatever it is, is called D, and so on. \n\nFAT32 is a MSWindows-based file-system, which is how the computer keeps track of what is stored on the hard drive. It seems like your hard drive is split into a least two partitions, C and D, with the D part of the drive storing (organizing) files using a FAT32 file system. \n\nThe FAT32 file system itself is not what's taking up the space -- it's all the files and data stored on that disk.

I can't remember exactly, but it has to do witht the way the laser and disk interact.  It is something like the disk has a mid-line in each track and the image is created on one side or the other of the mid-line.  If you have a CDR+ drive trying to write to a CDR- disk, the information will not be correct because the laser was writing on the "unformatted" side of the track.  Like I said I don't remember exactly, so maybe someone else will be able to expand or clarify on the explaination..

It at startup you press F12 it should let you boot from a utility partition. Then it should give you the option of running hard disk diagnostics.

It would say the disk was not formatted.

the first character in the disk directory is replaced with a zero that makes it appear to be deleted

you either have one hard drive with two partitions or two hard drives..  when you boot your system it will tell you but you can (assuming you have XP) click on start -> all programs -> accesories -> system tools --> system info.\n\nHere go to components -> storage -> drives\n\nThis will break out your drive info - you are interested in Local fixed disks.  It details size, space used/unused of each fixed partition.\n\nYou can also go to the control panel -> admin tools -> computer management -> storage -> disk management .  Here it will show you the disk layout and partitions.  If disk 0 has morethan one drive letter defined to the right of it then you have those partitions on a single hard drive (disk 0 is a single physical drive which can have 1, 2, 3... partions defined as C, D, E).

Yes, but if you've already written over the sectors where the data was stored, it's most likely beyond doing it yourself. STOP using the drive immediately and you may still be able to recover some data. There is a free data recovery program called Zero Assumption Recovery that you can try. Another program called Getdataback For NTFS ($100) is a better option than a freeware program.

Maybe your hard drive needs to be de-fragged?

Try defraging the hard drive. Click on start-click programs-scroll to accessories,system tools then click on disk defragmenter. While in the program click on analyze it will probably tell you it doesn't need defraging but defrag it anyway.

Buy a program that "bleaches" the hard drive space.  Simply formatting the drive still leaves data retrievable, it's just not seen by Windows.

Input / Output.\n\nIn short getting data in and out of the operating system or cpu from disk and memory.\n\nYou probably have a bad hard drive.\n\n...\n\nBad disks can usually still be partially read from. They are made up of many platters and parts. It may be that only a part of the drive is dead. To know for sure use a disk verification tool, it may be able to map around the bad parts is the drive motor itself is still okay.

one possibilty is it is doing a system check to see if there is any damage done to the files on your disk form the sudden nonsafe shut down.

Sounds like your hard drive is toast. Usually this kind of thing means there are bad sectors. I have heard there are some programs that can pull the undamaged data from the drive. Try searching Yahoo or Google. I am sure there are many sights in cyberworld with downloadable programs to recover lost data.

You just got your basic wrong. Try to reveal them again, and understand the ground physics first...\n\nThis webpage may help you to have preliminary understanding...\n\nhttp://computer.howstuffworks.com/hard-disk.htm

The mapping from logical to physical sector numbers on a magnetic disk designed to optimise sequential reads and writes. Data is usually transferred to and from the disk in blocks or sectors where one sector lies within a continuous range of rotational angle of the disk. If logical sectors are assigned sequentially to physical sectors (0,1,2,...) then by the time one sector has been read and processed (e.g. writen to main memory) the start of the next logical sector will have passed the read/write head and will not be accessible until the disk's rotation brings it back under the head.\n\nStaggering the physical sectors (e.g. 0,3,6,1,4,7,2,5,8) aims to allow just enough time deal with one sector before the next is accessible. This obviously depends on the relative speed of the rotation of the disk, sector size, sectors per track and the speed of transfer of sectors to main memory.
