|If you tell us which Systemax model you have, we may be able to help you better. The specific model is usually on a label on the outside of the case somewhere.|
E.g. you may merely need to change a setting in the bios Setup.
"If i switched the drive names, it was completely unintentional."
Nothing you have mentioned indicates you have changed any names.
The logical drive letter assigned to a drive partition is NOT it's name.
It's common to call each letter assigned in Windows a drive, but it's actually a logical drive.
A logical drive letter in Windows can be for the only partition on a physical hard drive, but not necessarily.
It sounds like you have one partition on each of the two internal hard drives. In that case, one logical drive letter is assigned to the one partition on the one physical hard drive, another logical drive letter is assigned to the one partition on the other hard physical drive.
However, there can be more than one partition on each physical hard drive, and in that case a logical drive letter is assigned to each partition on them that Windows recognizes (it has to be partitioned using a partitioning type XP recognizes - FAT, FAT32, or NTFS - and formatted), so in that case the number of logical drive letters is greater than the number of physical hard drives.
Each physical hard drive has a name - usually a model name -- however many partitions it has on it. That NEVER changes. However, that's not visible in My Computer ot Windows Explorer.
The name - usually a model name - is shown in Device Manager in Windows, and often on newer mboards, in the bios Setup.
E.g. RIGHT click on My Computer - select Properties - Hardware - Device Manager - open up Disk drives to see the list of hard drives.
In most cases their manufacturer's model names are listed, unless you have a relatively ancient hard drive, in which case it may show generic drive or similar.
In My Computer or Windows Explorer in Windows, XP doesn't assign a name - a label or volume label - to the drive by default, but you can assign a name to it if you so desire - a label or volume label - that does NOT normally change if the logical drive letter assigned to the drive changes.
RIGHT click on the logical drive letter - select Properties - type a name - label - you want to assign to the partition in the top box. Click OK to save the name - label. You then see that name - label - beside the drive letter in My Computer or Windows Explorer.
Installing software does not normally change the name - label or volume label - assigned to the partition - it's possible but that would be extremely rare for it to do so.
Older mboard bioses often assign drive letters to hard drives according to how the bios detects them and in what order they are detected and how they are connected/jumpered to the mboard - but they're not necessarily the same drive letters assigned to the same drives in XP
Running or installing software can but doesn't normally change the logical drive letter assignments, but loading bios defaults in the mboard's bios Setup, or clearing your cmos by moving a jumper on the mboard then moving it back, or flashing your bios with a newer version (update) or older version, or the same version, CAN change logical drive letter assignments of two or more internally installed drives, if the boot order in the bios Setup is changed by doing so
Or switching which IDE drive is on which connector on a 3 connector data cable when both on a data cable are jumpered CS (cable select) , or changing which drive is jumpered master or slave, or removing or installing a drive, CAN change logical drive letter assignments of two or more internally installed drives, if the boot order in the bios Setup is changed by doing so, or for other reasons.
You usually don't need to touch the existing jumpers for master or slave or cable select on the drives or change which connectors on a data cable they connect to (especially if you didn't do that just before the drive letters changed) . Just go into your bios Setup settings and change which hard drive boots first to the one you want to be C by finding and changing that in the boot order settings if each hard drive is listed there, not just one, or in a list of hard drives which is usually in on the same page as where you set the boot order settings.
The logical drive letters are assigned by default to external hard drives (and flash drives) in the alphabetical order, C and above, of the the first and lowest one after whichever drive letters were already assigned at the time they when they were plugged in. XP retains whatever drive letter was assigned until that particular physical drive is unplugged.
Under normal circumstances, if the logical drive letter assignments have not changed for some reason, that applies to internal drives.
XP retains whatever drive letter was assigned until that particular physical internal drive is unplugged.
E.g. If E was assigned to your CD or DVD drive, it retains that drive letter even if you unplug one of the drives that were assigned C and D.
