Why do I have four random partitions?
 
So, I was looking through my disk management for this new computer and I saw something unusual. I technically have six partitions, VISTA, recovery partition, and four random ones. I understand the data partition, but what is the need for a 12GB, 62GB and one GB partition? Also, if you add up all the partitions it comes to something around 370 GB, when I only have a 320 GB HD. What is up with that? Any ideas?

I guess I should have jazzed up the title...

On the question re the disk size 320 vs 370 a possible explanation is the somewhat misleading or misunderstood way for stating digital information storage. See http://en.wikipedia.org/wiki/Gigabyte for an explanation.

As for the number of partitions, there is a lot of reasons for more or less partitions and IMO has mostly to do with organisation of information. You can certainly do with only one but the HP Recovery one has a bit image of your HD as shipped from HP and if you ever need to revert to that state is worth keeping but certainly not manditory. It's essentially HP's way of providing you with a copy of the originally supplied software instead of, or maybe, in addition to supplying backup CDs. But being on the HD it can be lost if HD is repartitioned or in case of catastropic HD failure. If you maintain all of your data on the DATA partition you have the possibility of re-formatting your OS partition (usually the C: labeled one) without loosing your data. However in case of catastropic HD failure it will still be lost unless backed up. If there is nothing existing on the other partitions they can be deleted and the space reassigned to the partitions you want to keep. But be careful how you do that as there is potential of losing all the HD data in all partitions if done the wrong way, for instance using FDISK. I've successfully done it however using PartitionMagic. There is other equally safe(r) software for doing that and maybe it's even now built into Vista. Not sure though. If you don't actually need more space on your C: drive or DATA partition just yet just leave it as is and remember in the back of your mind that you have more available when/if needed.

You've got 2 hard drive in your computer.

Yeah, what's up with the two hard-drives??? Can you boot form the 1st active partition on the 2nd disk to see what it is?

Did the computer ship with BitLocker available, and a TPM (trusted platform module)? In Vista, you need to have a 1-2 GB partition for Bitlocker's system files.

The 11.72 GB partition confuses me. Only thing that can come to mind is it being a special bootstrap, but even that doesn't make sense.

It could be an image partition, for system restore.

The G: partition looks to be the system restore partition for the HP system. It is FAT32 (which is the standard for HP and dell partitions), and the size. The only thing that comes to mind for that 11.72 GB thing is a if Acronis TrueImage is installed, and its configured as a "vault" for documents.

Oh man, I feel like an idiot. I was looking at that screenshot again and I was like... why is that recovery called HP recovery?! My laptop is Asus! Then I realized my external hard drive was plugged in from my old laptop. Sorry guys, I just wracked my brain for naught. I am so stupid. I have the vista partition, data partition and a 11.72 GB partition. It is unlabeled but I am presuming it is a recovery partition. It seems like it would be labeled though. Also, I cannot find a recovery program like the one I had on HP. Sorry for the confusion and trouble, guys.

Heh, heh... I had a friend call me up panicking about erasing his HD by accident with all this data and no backups. He had installed a 2nd HD to do a clean install of Linux and some time during the install, he must have formatted the original drive. It didn't show up any where, not even in /dev, WTF???? Turns out he had removed the original drive for safekeeping and it was laying there on the floor under his desk!
