can't access partition normally after sp1 upgrade

[Guy999]

Hi

I've just upgraded to sp1 and I've found that I can't access one of my partitions through explorer.

Going via My computer works ok, but using explorer does nothing ie. doesn't respond and I have to close it.

I've disk checked my drive and it's ok... any ideas?

Thanks

Hi I've discovered that it does show up in explorer but after a long delay for some unknown reason. It's instant if I go via My Computer
