I was not sure which category to put this in I bought a little kit that lets me use my old internal hard drives as a external the problem is I hooked it up and it comes up as 2 local disk "local disk J"  "local disk K"  I only added a 400gb HD and came out like J has 99.9MB and K has 372MB why is it coming up as 2 and not one drive and add them together it is over 400 gb

First off you need to verify if it is MB or GB.  One may be MB and the other GB.  I'd guess the 99.9 is MB and the 372 is GB.  A 400GB drive would format out to something under 390GB.  The 10GB loss is due to hard drive manufacturers considering 1GB to be equal to 1,000MB and software companies considering 1GB to be equal to 1,024MB.

Since you say that these are old internal drives the 99MB partition is almost certainly an old Windows boot sector. If it bothers you you could re-partition this into one partition using all the available memory space. In the context of a 400 Gb drive 100 MB is irrelevant, unless my decimal points have slipped it is about 0.025% of the total drive - just ignore it, but that is the most likely explanation.
