2 xp problems (win update and stuck dir)

hi,

i have 2 problems:

1 when i want to open the 'documents and settings' dir in c:\,

it gets stuck for about 60 seconds, and then opens.

it's probably a bad sector or something similar.

one probable cause: a power shutdown in the home, during

a disk operation.

i tried error check in the properties-> reset and chkdsk,

but it didn't help.

2 during a windows update the power went down (in the home).

now auto update keeps wanting to install a patch for win live

toolbar. it keeps repeating it.

how to fix these things (without a total reinstall of xp)?

one more question:

i might want to install xp to external drive: e:\. from boot.

and then optionally reformatting c:\

will my xp installation on drive c:\ automatically be removed or disabled?

regards,

m
