Your tiles are probably there somewhere...\n\nTry booting in safe mode - delete all existing disks and controllers in device manager and let Windows re-detect them.\n\nTry swapping IDE cables and plug it into the secondary instead of the primary - or whichever's different.  Also use a different power connector.\n\nIf you have anything like Norton SystemWorks, try booting off of the CD and then check the disk from there.\n\nLook and ask around and see if you can find something you can burn to CD and boot from it.\n\nDo you have another disk on the system now?  Where are you sending this from?\n\nDON'T REFORMAT IT!

Don't listen to the answers below mine.\n\nFormat your hard drive.

It sounds like there is a lose connection between the hard drive and the motherboard.  Check your ribbon cable.  If that is not it maybe do a chkdsk/f to check for any errors the drive may have.

"Is there a virus that can format your hard drive?"\nIt could do\n\n"If your hard drive is formatted is there a way to find out how it was formatted?"\nNope, Everything is wiped clean off your hard drive\n\nI suggest you get an anti virus program, its free:\nhttp://www.download.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10503939.html?tag=lst-0-2

This sounds like a plug got lose.  Unplug the power cord (and main battery if this is a laptop) then remove the plugs in the drive, and reinsert them.   Then apply power and see if the drive is restored.  \n\nThis is just a shot in the dark, but I have seen this situation on a rare basis. \n\nGood luck

Sounds  strange.  Try right formatting the drive by right clicking on it.  This should work.

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

sounds like you have PC Alzheimers    reformat the hard drive and  start over.   C:/format   from the  command prompt

You possibly have a bad hard drive

Have you got a recovery disk?\n\nIf yes try that.\n\nIf no, seek expert help.\n\n///

Hmm, this could be any number of problems.\n\nYour best bet is to get someone experienced to take a little look. They will know what the problem is and how to fix it.\n\nIt doesn't necessarily mean that your hard drive is damaged or needs replacing - It could be something like a damaged partition table (which means you lost your files, but the drive is physically still usable). Or it could be bad sectors, a damaged MBR (easily repaired with 'fdisk /mbr' or anything else.\n\nDon't worry just yet. See what an expert has to say...\n\nJ

Perhaps you can purchase another reformat disk from the computer company.  Or might be better to buy a new  preprogrammed one that comes with the restores disks.  \nE

I would suggest you right click on my computer and go to manage and then that will bring up a console and you go to disk management and you should be able to see what it says about your external drive ie if its un allocated or w/e. Post back with that info, btw did this hard drive work correctly in your other computer before it broke down or did it break down because the hard drive broke down or what ?
