I need urgent help to fix my hard DISK. After LOOKING deeply into the problem, I found that my hard disk now only able to read the data off the partitions, but would not write any data to the disk. When I boot up my Windows XP, it just load for a while and freeze there, using check disk won't work as it refuse to scan. I couldn't even clear the MBR or reformat the partitions, not to say reinstall Windows. I TESTED the memory and it is not memory problem. I have no idea what is the problem, can anyone help? :-/have you try in "SAFMODE"?
if so, what HAPPEN?Safe mode won't help as it freeze half-way during loading. Just to give a bit of information about my system:
My computer is a notebook
Windows XP Home EDITION SP2
256MB + 512MB memory, 16MB used for video
My hard disk is separated into 2 partitions, no data can be written to any of the 2, but it can be read

While I not sure how the internal of a hard disk work, is there a separate read and write head?
Off the wall...(goin to be my c sign !!! K???) have U tried SCANDISK ??
In XP it is called Check Disk if I am not wrong, I have tried, the scan ended as soon as it is started. So it is unable to scan it.
