Wh don't we hav B: drive in our computer?Why Hard disk drive start with C: ? Can we alter or change to A:?

Answer 1

Why no B drive? It is the old convention.
A drive used to be the 5.25" floppy, B drive used to be 3.5" floppy and C used to be the HDD. This tradition continues.
A:\ now 3.5". Even this is changing now, most computers do not come with this drive because we have USBs and thumb drives.

Technology is constantly changing.

If you change the drive letters, certain programs won't work. They look for C:\ drive to set up all the application folders. It has been that way for years.

Unless you have good reason to change, don't.
Leave it well enough alone. Don't screw around too much and get yourself into trouble.

If it ain't broke, don't fix it.

Answer 2

WAY back in the early 1980s when CP/M computers and the first DOS computers were made, they had floppy disk drives, and there were almost always 2 floppy drives. The 2 floppy drives were given the letters A and B, while the 'C' letter was reserved for the hard-disk (if you could afford one).
These letter designators were even written into the BIOS on EPROM, so it became a standard.
So much software and firmware has been written over the decades assuming A and B are floppies, while C, D, etc. are hard disks, that it doesn't make sense to change, now.

Answer 3

A and B are reserved for floppy disk drives... even if you have a new computer in which floppies are pointless... Heres a more complete answer from wikipedia:

Under Microsoft's DOS operating system and its derivatives drives are referred to by identifying letters. Standard practice is to reserve "A" and "B" for floppy drives. On systems with only one floppy drive DOS permits the use of both letters for one drive, and prompts to swap disks. This allows for copying from floppy to floppy (this isn't a very fast method though as it generally ends up asking for disk swaps far more often than really needed) or having a program run from one floppy whilst having its data on another. Hard drives were originally assigned the letters "C" and "D", but as support for more hard drives became available this developed into assigning the primary partitions on each drive (DOS only allows a single active primary partition per drive even though the partitioning system allowed for more) letters first, then making a second pass over the drives to allocate letters to logical drives in the extended partitions. Letters for CD-ROMs, RAM disks and other things are allocated after the hard drive partitions. This is often done simply in the order the drivers were loaded, although many drivers can be specifically instructed to take a different letter. Network drives are usually given letters much further on in the alphabet by the network driver software so that they are generally out of the way of this system.

Because these letters are used directly by normal applications (unlike the /dev/* names in Unix-like operating systems), the addition of an additional hard drive can be disruptive to applications, which then require reconfiguration or even reinstallation. This is especially true if there are logical drives in an extended partition on the original hard drive and the new hard drive has a primary partition, as it would then cause the logical drives on the first hard drive to change letters. However, even if the new hard drive had only logical drives in an extended partition it would still disrupt the letters of RAM disks and CD-ROM drives. This disruptive system persisted through the 9x versions of Windows but NT adopts a slightly different system. It uses the traditional rules when first installing but after that it tries to preserve the letters of existing drives until you change it.

Answer 4

A and B are assigned for floppy drives.You can connect 2 floppy drive in tandem which will be assigned as A or B drives.
The hard drive is always assigned as C followed by D till Z depending upon the partitions created in the hard disk.if the hard disk has just one logical partition then the CD Drive will be assigned as the D drive.

Answer 5

There used to be a B: drive. Back in the days of 5.25 inch floppies, that floppy drive was the B: drive.

You can change drive letters by going to Control Panel -> Administrative Tools ->Computer Management -> Disk Management.

Answer 6

early computers had two floppies. A and B. When hard drives were added they then were C. When Floppies were decreased to one. Then it became A and C. then when optical drives came in it was A, C and D. Now computers don't have floppies and it is C and D or sometimes C,D,E. I needed a floppy on mine and my memory stick shows up as another so I have A,C,D,E and sometimes F. When the stick is plugged in.

Answer 7

The operating systems are designed to assign the drive letters according to the following algorithm:

1. Assign the drive letter 'A' to the boot floppy, and 'B' to the secondary floppy.
2. Assign a drive letter, beginning with 'C' to the first active primary partition recognised upon the first physical hard disk.
3. Assign subsequent drive letters to the first primary partition upon each successive physical hard disk drive, if present within the system.
4. Assign subsequent drive letters to every recognised logical partition, beginning with the first hard drive and proceeding through successive physical hard disk drives, if present within the system.
5. Assign subsequent drive letters to any RAM Disk.
6. Assign subsequent drive letters to any additional floppy, CD/DVD drives.

NO. We can't change the drive letter C: to A:

Answer 8

A and B drives are normally reserved for the floppy drive, if you really want, you can change your C drive to anything else. The new computers don't have floppy drives so A and B drives are reserved for USB drives.

Answer 9

whoa, you're extremely showing her, hm? you need to be so smart, to reason a lot distraction, and get round that 'discovering stuff'.... at this fee you'll go away college as stupid as you began it. the difficulty isn't your instructor, yet you and your college associates, who do only not comprehend why you're in school interior the first position. Hell-o!!!! you've not got to any extent further some thing to be happy with. Your behaviour is infantile (seem it up in a dictionary, in case you may truly examine) and is getting you nowhere. perhaps you've a discovering difficulty, and also you try to deflect your embarrassment through attempting to bypass time in school being a goof off somewhat of truly attempting to study. for that reason, you pick professional help (counselors, or maybe a instructor, are you able to imagine?)

Answer 10

Normally A is reserve for 3.5 inch floppy while B is for old 5.5 inch floppy and finally C for ur hard disk. After ur hard disk the on coming alphabet will be ur optical drive and all other storage devices like pen drive. i dun think it is possible for u to alter tat.
