Hi I m creating a file which will serve as a virtual harddisk .
I m using following command to create a file.
I have following doubts regarding the operation.
1) In above example i m creating a file with byte size of 1M .However in windows O/S (Not sure about linux here) whenever a new partition is formatted the default size will be 4096 bytes.
2) According to my assumption it doesn't make any difference as OS is anyway going to format it using mkfs.(whatever filesystem we specify).
Correct me if i m wrong.

mkfs.minix
MKFS.MINIX(8) System Administration MKFS.MINIX(8)NAME
mkfs.minix - make a Minix filesystem
SYNOPSIS
mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] device [size-in-blocks]
DESCRIPTION
mkfs.minix creates a Linux MINIX filesystem on a device (usually a disk partition).
The device is usually of the following form:
/dev/hda[1-8] (IDE disk 1)
/dev/hdb[1-8] (IDE disk 2)
/dev/sda[1-8] (SCSI disk 1)
/dev/sdb[1-8] (SCSI disk 2)
The size-in-blocks parameter is the desired size of the file system, in blocks. It is present only for backwards compatibility. If omit-
ted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed.
OPTIONS -c Check the device for bad blocks before creating the filesystem. If any are found, the count is printed.
-n namelength
Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30. The default is 30. Note that kernels
older than 0.99p7 only accept namelength 14.
-i inodecount
Specify the number of inodes for the filesystem.
-l filename
Read the list of bad blocks from filename. The file has one bad-block number per line. The count of bad blocks read is printed.
-1 Make a Minix version 1 filesystem.
-2, -v Make a Minix version 2 filesystem.
-3 Make a Minix version 3 filesystem.
EXIT CODES
The exit code returned by mkfs.minix is one of the following:
0 No errors
8 Operational error
16 Usage or syntax error
SEE ALSO mkfs(8), fsck(8), reboot(8)AVAILABILITY
The mkfs.minix command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
