No, you do NOT use FDISK. You just set the jumper on the second hard disk
to S(lave) and attach the second connector of the IDE cable to it. Then
switch on and set the Setup to the number of cylinders etc which (if
you're lucky) is printed on the label of the HDD.
You only need FDISK if you have to partition the disk.
I recommend removing the present hard disk and running all the setup
stuff from a floppy disk. With MSDOS622 that I use, it requires making a
boot floppy and copying DEBUG.EXE, FDISK.EXE and FORMAT.COM to this boot
disk.
I strongly recommend doing a low level format on any secondhand hard
disk. With most computers, the MSDOS 6.22 commands that work will be
1) DEBUG to load DEBUG
2) G=C800:5 once DEUBG is loaded, to start the low level format
3) Q to quit debug.
This process is slow, but it will rewrite all the track and sector
markers that FORMAT can't get at, and it will also totally remove any
hidden viruses and other nasties that may be lurking on the disk.
Then you need to do an FDISK to set up the disk as a single partition,
or as multiple partitions if the HDD is larger than the computer and DOS
can handle. In my case with MSDOS622 on a 486, that limit is 512meg.
Then each partition needs to be formatted. If this is to be the main
hard disk eventually, then the first partition must be formatted as a
boot disk, using the command "FORMAT C: /S"

My 486 running MS-DOS 6.22 can't handle anything larger than 512m.
However, I'm told I can install *any* size disk and partition it with
FDISK to whatever number of partitions as long as none of them is larger
than the max size my system can handle, in my case 512meg. OTOH that is
outside my present experience so I don't know whether it's correct.

As above to set up the disk. Then with the computer switched off, set
the jumper on the new disk to [S]lave and reconnect the old HDD to the
cable -- if there isn't room inside the case, one of them will have to
hang outside for the present.
As you start up, you'll have to redo the setup for the two drives.
The new HDD (or the first partition on it) will be the D: drive and the
old HDD the C: drive. You can now execute "XCOPY C:\*.* D: /S". The "/S"
causes XCOPY to recurse all the subdirectories and it makes a full copy
of the C: drive on the D: drive.
Then switch off, remove the old HDD, and change the jumper on the new
one to [M]aster, switch on and redo the Setup.
You should now see the new hard disk as the C: drive, and any extra
partitions on it as D:, E:, etc...
