Hi I m creating a file which will serve as a virtual harddisk .
I m using following command to create a file.
#dd if=/dev/zero of=/tmp/Sample.dat bs=1M count=1024
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.
3)Will it make any performance issue ?
