A fragmented source disk can slow down the process of finding, reading, or writing files.īecause diskcopy makes an exact copy of the source disk on the destination disk, any fragmentation on the source disk is transferred to the destination disk.
This process continues until you have copied the entire disk.įragmentation is the presence of small areas of unused disk space between existing files on a disk.
Diskcopy reads from the source disk, writes to the destination disk, and prompts you to insert the source disk again. If the disks contain more information than the available memory can hold, diskcopy cannot read all of the information at once. If floppy disk drive1 and floppy disk drive2 are the same, diskcopy prompts you to switch disks. Run diskcopy from a drive other than the floppy disk drive, for example the C drive. If the current drive is the same as drive1, diskcopy prompts you to swap disks as necessary. If you omit both drive parameters, diskcopy uses the current drive for both. If you omit the drive2 parameter, diskcopy uses the current drive as the destination drive. If the source disk has a volume serial number, diskcopy creates a new volume serial number for the destination disk and displays the number when the copy operation is complete. Diskcopy displays the following message while it formats the disk and copies the files: Formatting while copying If you're copying to an unformatted floppy disk in drive2, diskcopy formats the disk with the same number of sides and sectors per track as are on the disk in drive1. If you press Y, diskcopy prompts you to insert source and destination disks for the next copy operation. The diskcopy command prompts you to insert the source and destination disks and waits for you to press any key on the keyboard before continuing.Īfter it copies the disk, diskcopy displays the following message: Copy another diskette (Y/N)? Specified drive does not exist or is nonremovable If you specify a hard disk drive for drive1 or drive2, diskcopy displays the following error message: Invalid drive specification You cannot use diskcopy with a hard disk.
This option slows down the copying process.ĭiskcopy works only with removable disks such as floppy disks, which must be the same type. Verifies that the information is copied correctly. Specifies the drive that contains the source disk. If used without parameters, diskcopy uses the current drive for the source disk and the destination disk. Copies the contents of the floppy disk in the source drive to a formatted or unformatted floppy disk in the destination drive.
