The only problem may be a BIOS limitation, check
your motherboard for this.
But dont forget to consider the SLACK or lost
space from larger cluster size and also the
performance hit you will encounter from having
all 120GB as your boot drive.
If I were you, I would create a 10GB partition for
only OS and related updates, service packs etc-
no programs or anything else.
Then partion the rest of the drive for everything
else. Just my opinion.
What are u talking about? why would BIOS limit him from managing partitions?
and he will not loose any space from cluster size, unless he specified a different cluster size for one of his partitions in the first place. the avalible space ona 60gb partition witha 4k cluster size will be equally perportional to a 120gb partition witha 4k cluster size.
and there is no performance hit from booting off of a 120gb partition as compaired to a 10gb partition... no matter how its partitioned ITS STILL THE SAME PHYSICAL 120gb HD.
NTFS performse better conserning 1 HD if it only has 1 partition on it. if you partition it, it now has to keep track of 2 seperate file spaces instead of just 1. only posible benifit from partitions may be keeping disk less fragmented, but thats only if you have problems with fragmentation in first place, and u can always just Defrag the HD anytime u wont.
If i only ownd 1 HD, i would partition it to keep OS seperate because incase it crashed and i had to reinstall the OS. because i store files on my comp i would keep them on the 2nd partition, safe from the reformat proccess. <-- thats the only reason i c to partition.
