help: new 6210, unexpected partition error

I just got my 6210 yesterday. Today I installed PQ magic and plan to repartition it. However, I find the primary disk is shrinked to 5G, besides the 2G backup disck originally there, I find roughly 30G unallocated disk. 5G for primary disk is unacceptable to me, so I create two new partitions and resize the primary disk to 10G. However, when performing the resizing, there is something like "1534 error, cluster crosslinked or not allocated." I restart the computer and find the primary disk remains 5G, and the 5G originally set to be reallocated to it now become unallocated. Whenever I plan to merge the primary disk to resize it, the error pop up, some time it's "too many errors", some times 1534 error. I don't know what happens. I seach the web and symantec site says "The only solution available is to backup, delete, and restore the affected partition."

I also encounter problem with Norton Anti-virus preinstalled. I update it on-line and find the main program cannot be upgraded, some file called navwnt.exe.

Anyway I plan first to uninstall Norton, but I don't think this will solve the partition problem. Any ideas? If I repartition and restall everything, is it too hard?

 

I installed another version of Norton, and it runs alright. And now the partition error become 501 error, still the cross-link error, and I run chkdsk and correct one. The redo it, still 501 error, however, after reboot twice, I find the two partitions are actually merged. It's wierd. The partition is still not what I want, so I'll try another time to see whether it can work again.

 

run error checking tool and chkdsk one by one two times and fixed it.
