The disadvantage to the software vendor is if he/she don't get it right,
they can wipe out the whole disk drive, partition and file tables, as they
are bypassing the Win2k disk API's - which is risky, but many of those large
companies have special agreements with MS and they help to ensure this
doesn't happen. The smaller software vendor don't have the budget or
capital to compete and as a result don't have options the big guys do.
Small note - I believe Norton (don't know about the others) splits the
pagefile into equal sizes and each are moved to the begining of a different
platter as my pagefile is always framented into exactly twice the number of
platters my drive has after defragmentation - seems too coincidental to me -
but then again, I could be lucky/unlucky depending on your outlook:-)
