Recovering data from Windows Crash

I really want to get access to my disk at least for once and recover my important data but I am unable to do that. Actually the windows on my old Sony PCG FX140 laptop got corrupted and now it’s not loading. When I start the Windows Me, after the logo there comes a blue screen showing me the error saying; error message 'scandisk has caused an error in msvcrt.dll scandisk will now close If you continue to experience problems, try restarting your computer''. When you close that, it says "rundll32 has caused a problem in msvcrt.dll", then ssdpsrv, then spool 32, then stimon, then statemgr, the scrolling marquee, then it starts with scandisk again.
I tried my best level to recover the data but I was failed in doing so. The main problem is Windows are not loading. I got to know from an online helping source that scandisk needs to be reloaded and a hardware technician told me that hard drive has a bad cluster and it needs to be replaced. At the same time I don’t want to invest that much in that computer because of its being very old. Please help me out in matter and let me know the ways if there are any to get access to my disk at least for once. I would be very grateful.
Thanks
