Upgrading Old to New Hard Drive on Win95 PC
Here is the procedure I follow to replace a Win95 PC's hard drive with a larger
hard drive. Part of this info was adopted from the Oct 96 Columbus Computer
Society newsletter. The rest comes from my personal experience and help from the
people at Dramen.
- Insure you have a StartUp Disk for your computer.
If not, go to Control Panel, Add/Remove Programs, and select the Startup Disk
tab. It's also a good idea to copy your CD-ROM drivers to this startup disk so
booting from the floppy will also allow you access to the your CD-ROM and
therefore your Win95 CD so you can recover your system in case of a crash.
If your CD-ROM is defaulting to the next available drive (e.g. D:), then this
may be a good time to force it to be a higher drive letter so its drive letter
does not automatically change when you add new hard drives.
I set mine to G: using the System/Settings for the CD-ROM under Control Panel.
- Power-off PC and install new hard drive.
The new drive is added based on your current configuration:
- Current hard drive is hanging off the primary IDE port and cable has
connector available for a 2nd drive.
In this case, connect the new hard drive as a slave drive off the same
IDE cable as the current drive. The current hard drive must have its
jumpers set to be the master drive, while the new hard drive must have
its jumpers set to be the slave drive.
- No room on primary cable, so check using secondary IDE port.
- If the secondary IDE port is free, then connect new hard drive as master (make
sure you have an IDE cable to do this).
- Secondary IDE port already has a device (maybe a CD-ROM), so add
new hard drive as a slave drive to this cable.
- Reboot your PC, entering the System Setup BIOS
- Use BIOS auto-detect hard drive command to configure new hard drive as the
2nd hard drive in the system.
Save BIOS settings and exit so computer reboots from startup floppy.
- Run FDISK from floppy, select 2nd drive (i.e. the new one) as default,
then create primary DOS partition (max size is 2G).
Insure primary DOS partition on new drive is same/larger than C: drive on
Create extended partitions for the remaining space on the new drive.
Exit FDISK, remove startup floppy, then reboot PC so it comes up in Win95 using
the old hard drive.
- From Win95 desktop, select MS-DOS Prompt from Start/Programs.
Must use this Win95 MS-DOS window as opposed to restarting in MS-DOS mode.
The primary partition on the new drive will be D: and any extended partitions
will be E:, F:, ...
If your old hard drive had more than one partition (e.g. C: and D:),
then C: and D: are the primary partitions on the old and new drive, respectively,
but the old D: drive becomes E:, the first extended partition on new drive
becomes F:, and they alternate in similar manner for any extra drives.
Format the primary partition on the new drive with the following command:
and format any extended partitions (e.g. E:, but see above for how drive
assignments will occur) with the command:
- Next copy the old primary partition (C:) to the new primary partition (D:) with
the DOS command:
xcopy32 c:\*.* d:\ /e/f/h/r/k/c
This command copies everything from C: to D:, including the registry files and
keep long file names intact.
If you had extra partitions on your old hard drive (e.g. your old drive D: which
is now drive E:), then use same copy command to move files to new partition:
xcopy32 e:\*.* f:\ /e/f/h/r/k/c
- Shut down the PC, turn off power, remove old hard drive and put the new hard
drive in its place. Remove to change new hard drive jumpers to master settings.
- Power on PC, enter BIOS Setup, then run auto-detect hard drive to assign
new drive is primary drive and delete the secondary drive.
Insert startup floppy, save BIOS settings and exit so PC will restart from
startup floppy. Run FDISK to set the new drive as active, then exit FDISK
and run this command to make the new drive bootable:
- Remove startup floppy and reboot PC.
It should come up into Win95 from the new hard drive.
If you run into problems getting it to boot, you may boot from the
Startup floppy and run FDISK /MBR and then SYS C: again to see if
that corrects the problem.
