Hi,
Owen. Using winXP I have seen a number of variations when drives are installed. Partitions, too. Because you mention D:\ is being used as "recovery" I'm thinking that you describe something that HP has done
using winXP.
I say that because I have no "recovery" on my PC.
I load from an OperatingSystem(OS) CD. Your computer may have been sold without that kind of disk. So, it has instead a part of the hard drive that it reserves for a "fresh" copy of all the files that make up the OS. If you as a user decide you want to start over again without all the stuff you put on the computer since you bought it you would enact that process in much the same way I do when I insert the OS CD to re-install.
Reinstallation requires that either the entire HD be wiped clean of data and re-formated to accept the OS files, or that
part of the HD that contains the OS files needs to be wiped clean and re-formatted.
Parts of a HD that are formatted, to be in some ways "independant" of other parts, are called
partitions. They are seen by windows as individual drives with letters assigned to them.
You might have 2 HD's and 5 drive letters assigned, perhaps. So in
My Computer and also in the Storage console of your
Computer Management feature you'll see
- DISK1 VOL1 (C:\) local disk
- DISK1 VOL2 (D:\) local disk
- DISK1 VOL3 (E:\) local disk
- DISK2 VOL1 (I:\) local disk
- DISK2 VOL2 (J:\) local disk
or some variations of that basic plan.
Letter 'A' is usually reserved for a floppy drive. I think default provides for the Optical Drives (CD-ROMS, CD-RW's & the DVD counterparts) to get letters "F" & "G". Letter "B" I've never seen used unless a second floppy was in place.
The
Primary Drive (or partition of a drive) being only the
one that has the OS files on it, and those are:
- Documents and Settings (which includes all sub-folders & files)
- Program Files (which includes all sub-folders & files)
- WINDOWS (which includes all sub-folders & files)
being called C:\ by default....
you can have drive letters of D, E, H, I, J, K etc. for the other(s) you might have.
All
other partitions and/or additional HD's Windows "sees" as non-primary (also called BOOT drives) or
Secondary drives. Also called (additional storage drives).
Please note that it is also possible to have
only operating systems files on your C:\ drive.... but not likely.
The first file/folder you create yourself will probably land in My Documents, which is a sub-folder of one of the three main folders that all of WindowsXP version/any calls it's own.
Same with any installed program you download/install or slip a CD into and go from there
without exercising your choice about where to install
TO.
Most programs by default will install to C:\Program Files\'programname'. They also also usually allow you to browse for an option.
Those that do not, you can create a folder in another location before you install, so there is a location other than C:\Program Files available when you continue with the InstallWizard operation. Like E:\Program Files... one you made, for instance.
The value in that is that your C:\
partition never gets modified from original state as much. Your program files are on another partition, and your Data, also. Basically only things you choose to go into My Documents & things that programs (some of them) might by default send to those windows files. Thats the beauty of it. Only some programs will modify the folders in your Windows OS. Even fewer will modify particular files. Malware for instance can in some case.
Its easier to find .
The Registry will be modified constantly as you use the PC, and it is of course a windows folder. System Restore (not to be misunderstood to be "recovery" files/folders like you mention are on your D:\) will modify each HD as it works, too.
These two things, and few others, are a lot less action than if you add all of your data and programs into it from the start & never stop doing it.
Smaller partitions reserved for specific purposes is what HP does when they bundle Windows into the PC they sell. Users who build there own also do this & of course plenty of others. The fact remains:
WindowsOS can operate on a single HD with it's required-as-format partition the whole drive (one letter)
orany number of partitions (which are essentially "sub divisions") on a single HD (more letters).
Modifications of your drive can be accomplished in a couple ways I know of:
- Using software developed by HD manufacturers, like MaxBlast3.
- Using the Disk Mangement console in Computer Management
- found by -->Start-->Control Panel-->Performance & Maintenance-->Administrative Tools-->Computer Management (left pane, std. tree arrangement)-->Disk Management
Ask a simple question, ya' don't always get a simple (or even the one you're lookin' for) ANSWER.

My computer wont recognize it.
Darn it. Why not? Is it plugged in? J/K
how to get Windows XP to assign a drive letter
There is a way. Let's wait a see who knows it, huh?
