Why drives starts form C:\ Not from a or b ?

Why windows drives start for c drive not from A OR B even there is no use for both of them.

 

If only one physical floppy is present, drive B: will be assigned to a phantom floppy ... Starting with DOS 5.0, the system ensures that drive C: is always a hard disk, ... SYS file (e.g. the controller card does not offer on-board BIOS or using this

 

I also wonder why this happens too, i have always wanted to ask but it sounded silly.

 

I don't know. And trying to know the answer of this question.

 

There is something called BIOS.

Actually you can change what drive your PC will boot first.
And more actually, that thing is used when formatting your PC,
we boot your PC using your CD-Rom or what-so-ever that is normally NOT C:

Hope this helps.
And I do not know if your thread is in correct fora.

 

Can I use my first drive name from a or not

 

becasue a is for floppy disk and b is for cd rom always

 

there used to be drive a and drive b at one point in time which were 3.5 and 5.25 inch floppy disks. thats why hard drive starts from c

 

That is because in earlier days, A is used for floppy disk. B is used for a bigger floppy disk.

 

Because

• A: — Floppy disk drives, 3.5" or 5.25", and possibly other types of disk drives, if present.
• B: — Reserved for a second floppy drive, if present.
• C: — First hard disk partition.
• D: to Z: — Other disk partitions get labeled here. The letter D: or E: are often assigned to CD-ROM, DVD drives but not always.
• F: — First network drive if using Novell NetWare.
• L: - Dynamically assigned "load drive" under Concurrent DOS, Multiuser DOS, System Manager and REAL/32.[SUP][7][/SUP][SUP][8][/SUP]
• M: - Drive letter for optionally "memory drive" MDISK under Concurrent DOS.[SUP][7][/SUP]
• N:, O:, P: - Assignable "floating drives" under CP/M-86 4.x, Personal CP/M-86 2.x, DOS Plus 1.2-2.1 (via BDOS call 0Fh), a concept later extended to any unused drive letters under Concurrent DOS, Multiuser DOS, System Manager, REAL/32 and DR DOS up to 6.0.[SUP][7][/SUP][SUP][8][/SUP]
• Q: - Microsoft Office Click-to-Run virtualization.
• Z: — First network drive if using Banyan VINES, and the initial drive letter assignment for the virtual disk network in the DOSBox x86 emulator.

 

I think the use of Floppy disks has no longer available and fuure operating systems will come as A for the first HDD.

 

they are standard format in dos command in my openion

 

A is for floppy disk.

B is for the second floppy disk.

C is for hard disk.

 

A and B drives are reserved for Floppy drives to get back up from hard disk, if the hard disk is crashed.

 

Drives A: and B: both existed when diskettes were still the most useful storage media during the 90's, while C: has always been the known location for Windows installatio until today. Perhaps it has been agreed to keep the labeling of the drives that way.

 

A and B are reserved for floppy drives, so the default startup on appear as C： .

The floppy drive has been eliminated. Are interested, you can use the u disk to emulate a floppy drive.

 

Probably because it's stands for Computer? lol

And I think it's easier to remember everytime you think about PC or Computer...

 

It used to be the 3rd drive when computer was first introduced, A was the primary before when they first used floppy, not till CD's were introduced.

 

thank you Jhonyy for giving this information.actually it is a very basic question but most of the people does not know this question.i did not know the answer of this question.
