Cloning (and expanding) a 60GB PS3 HDD to a 320GB HDD

These are the steps that were taken to clone a 60GB PlayStation 3 (PS3) HDD to a 320GB HDD, and then expand the USERDATA partition to the full size of the new disk using a NetBSD VM.

Clone the Drive

The original 60GB HDD was cloned to an image using ddrescue.

Original disk: /dev/loop0 (mounted 60GB HDD image file) New Disk: /dev/sdd (320GB HDD)

    sudo ddrescue -fn /dev/loop0 /dev/sdd diskcopy.log

Output:

    andrew@mint:~/ps3$ sudo ddrescue -fn /dev/loop0 /dev/sdd diskcopy.log
    GNU ddrescue 1.23

                                time since last successful read:         n/a
    Finished

Decrypt and Mount the 320GB HDD

Running lsblk should yeld output like this.

Backup CACHE partition

This partition needs to be relocated to allow us to extend USERDATA. Create an image of it that we will later restore.

Update Partition Table

Run PS3 HDD Expander.sh to extend USERDATA and relocate CACHE.

Expand the maximum size the partition can be (317656989696 bytes).

    ./'PS3 HDD Expander.sh'

Output:

    /dev/sdd total sector count: 625142448
        320072933376 bytes, 298 GiB

    1) Safe max bytes for USERDATA:
        316753838080 bytes (295.000 GiB)
        618659840 sectors
        This size has proven to most reliable in testing

    2) Warning USERDATA would round up:
        317656989696 bytes (295.841 GiB)
        620423808 sectors
        This is the maximum size the partition can be

    3) Max bytes without round up for USERDATA:
        317290708480 bytes (295.499 GiB)
        619708415 sectors

    4) Custom Size
    Select USERDATA partition size: 2
    No changes made to LBA_USERDATA_LENGTH

Running lsblk should now yeld output like this:

Extend USERDATA partition UFS file system using NetBSD 6.0

See here for details of configuring a NetBSD 6.0 VM

    sudo qemu-system-x86_64 -smp 2 -m 2g \
                -drive file="$HOME/Downloads/NetBSD-6.0-amd64.qcow2",format=qcow2,if=virtio \
                -drive file=/dev/mapper/ps3hdd2,format=raw,if=virtio \
                -nographic

The PS3 partition should be /dev/ld1a. You can list all drives with sysctl hw.disknames.

Note NetBSD refers to UFS as FFS. This version appears unable to mount the PS3 partition, however all utility programs seem to work fine.

    # mount -v /dev/ld1a /cell_mw_cfs/ 
    exec: mount_ffs /dev/ld1a /cell_mw_cfs
    mount_ffs: /dev/ld1a on /cell_mw_cfs: incorrect super block

View disk summary

    fdisk /dev/ld1a

Output:

    No active partition.

Pre-extend fsck

    fsck_ffs -yf /dev/ld1a

Output:

    # fsck_ffs -yf /dev/ld1a
    ** /dev/rld1a
    ** Swapped byte order
    ** File system is already clean
    ** Last Mounted on /cell_mw_cfs

Extend file system with resize_ffs

    resize_ffs /dev/ld1a

Output:

    # resize_ffs /dev/ld1a                                                         
    It's required to manually run fsck on file system before you can resize it

    Did you run fsck on your disk (Yes/No) ? yes
    #

Post-extend fsck

    fsck_ffs -yf /dev/ld1a

This produced a ton of output on the first run.

On the second run the output was:

    # fsck_ffs -yf /dev/ld1a 
    ** /dev/rld1a
    ** Swapped byte order
    ** File system is already clean
    ** Last Mounted on /cell_mw_cfs
    ** Phase 1 - Check Blocks and Sizes

Shutdown the NetBSD VM.

Unmount Drives

Use PS3 HDD Umounter.sh option 1 to unmount everything.

    ./'PS3 HDD Umounter.sh'

Return drive to PS3

Successfully boots.

PS3 reports 263 GB / 298 GB free

Bonus: change normal user free space reserve from 8% to 1%

In NetBSD run:

    tunefs -m 1 /dev/ld1a

Output: # tunefs -m 1 /dev/ld1a tunefs: /dev/ld1a: swapping byte order tunefs: tuning /dev/ld1a tunefs: minimum percentage of free space changes from 8% to 1% tunefs: should optimize for space with minfree < 5%

The PS3 now reports 283 GB / 298 GB free

NetBSD 6.0 amd64 QEMU VM

These steps were tested on a Linux Mint system:

    Linux mint 5.15.0-88-generic #98-Ubuntu SMP Mon Oct 2 15:18:56 UTC 2023 
    x86_64 x86_64 x86_64 GNU/Linux

qemu-system-x86_64 version:

    QEMU emulator version 6.2.0 (Debian 1:6.2+dfsg-2ubuntu6.15)
    Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers

You can append -enable-kvm to the qemu-system-x86_64 commands below to enable full virtualisation, if your OS installation and hardware allow it. Test by running kvm-ok.

Creating a NetBSD 6.0 QEMU VM

A pre-built disk image based on these steps can downloaded here:
https://archive.org/details/NetBSD_6.0_amd64_qemu_vm

  1. Download the installation ISO from the NetBSD archive.

    https://archive.netbsd.org/pub/NetBSD-archive/NetBSD-6.0/iso/NetBSD-6.0-amd64.iso

  2. Create a virtual disk.

    qemu-img create -f qcow2 "$HOME/Downloads/NetBSD-6.0-amd64.qcow2" 16G

    Command output:

    andrew@mint:~$ qemu-img create -f qcow2 "$HOME/Downloads/NetBSD-6.0-amd64.qcow2" 16G
Formatting '/home/andrew/Downloads/NetBSD-6.0-amd64.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=17179869184 lazy_refcounts=off refcount_bits=16

  3. Start the QEMU VM for installation.

    sudo qemu-system-x86_64 -smp 2 -m 2g \
    -cdrom "$HOME/Downloads/NetBSD-6.0-amd64.iso" \
    -drive file="$HOME/Downloads/NetBSD-6.0-amd64.qcow2",format=qcow2,if=virtio

  4. Proceed through the Install NetBSD to hard disk option, using the defaults except for:

    • Installation without X11
    • Bootblocks - use serial port com0 9600 baud (this makes it easier to output to the terminal when using -nographic)
    • Root shell - /bin/ksh

  5. Once the installation is complete select Exit Install System and shutdown the VM. Once the system has been halted close the QEMU window to end the process.

Running the QEMU VM

    sudo qemu-system-x86_64 -smp 2 -m 2g \
        -drive file="$HOME/Downloads/NetBSD-6.0-amd64.qcow2",format=qcow2,if=virtio \
        -nographic

All output will be in the terminal you run the process from.

Log in with root and no password.

How to change keyboard layout

Quick reference for disk commands

These are current version docs so may not be 100% accurate to version 6.0

After shutting down the VM you may have to kill the process, otherwise it sits at a system halted prompted.

Passing a PS3 partition through to the VM

    sudo qemu-system-x86_64 -smp 2 -m 2g \
        -drive file="$HOME/Downloads/NetBSD-6.0-amd64.qcow2",format=qcow2,if=virtio \
        -drive file=/dev/mapper/ps3hdd2,format=raw,if=virtio \
        -nographic

The PS3 drive should be seen as /dev/ld1a.
