Hello , well i m not tech freak so please let me know what if you can help. i have this problem which one yesterday when it just came with big warning that my labtop was infected . so i started to shut down it and i have I've tried everything, here is a list of what I tried. After each item, the computer stops responding when it's time to start up Windows. - Safe Mode. - Safe Mode with Networking. - Safe Mode with Command Prompt. - Enable Boot Logging. - Enable VGA Mode. - Last Known Good Configuration (your most recent settings that worked). - Directory Services Resore Mode (Windows domain controllers only). - Debugging Mode. Disable automatic Restart on system failure. Then I attempt to insert the "Operating System CD", so I can either repair or reformat but this didn't work and now i have this massege : FORMATING 28,31.7M TRYING TO RECOVER ALLOCATION UNIT 145,718 and it keep counting from last night . i hope that i didn't miss up. thank you so much

It appears that your hard drive might have died. If you have a Toshiba CD to check the hard drive, run it.

thats what i m doing Toshiba recovery CD ..but as i said its still counting .thanks

Have you followed the routine as posted here? http://kb.wisc.edu/helpdesk/page.ph... Also as suggested above... see if the Toshiba site has util to ceheck/tet your HD; - and if you know what make the HD is there will likely be a util on the website for the drive that will allow you test/check the drive for problems... If possible avoid writing to the drive at all... If you have or can secure a "linux on a CD" variant (knoppix, ubuntu etc.) then boot with that and see if you can at least "access" the drive that way. The linux OS will run from the cd; and may at least allow you transfer off data etc to optical media. Then you can set about finding out what's amiss with the drive...? Data recovery is usually (and natrually) the first concern, and the above routine may allow you that much at least...?

all this failed i guess ...do you have another idea ..please thank you

Are you saying that boooting via Linux (on a cd) didn't see the drive; and drive test utils also failed to see it or give you any useful info about it? I wouldn't be prepared to say the drive is toast just yet; as the error messages you got intially don't all lead to that conclusion...
