Downloading and Imaging a new HDD for Tivo

What you should be doing now is downloading the NZ customised images from the nzTiVo images repository and following the menus. These are menu driven install disks which once booted basically guide you through the imaging process. Information about these images is here.

NOTE: This document is for the older OzTivo Image 1.3. If you really want to use the older install, you may want the version with screenshots at ImageWithScreenShots. There is also ImageWithScreenShots1.4 (which helps with 1.4, 1.5 and 1.6.2) (it also has helpful screenshots). But you should really use the nzTivo Image mentioned above.

Thank you to OzTiVo for their Guided Setup Document, which makes up the bulk of this document.

Download Image
Download current ozTivo image here or local NZ mirror here Note: Stay tuned for a NZ image, as soon as someone gets around to creating it! Update: The nzTivo image is now available. See at top of page.

There are other images avaiable in the parent directory, these are for upgrading existing systems. This procedure will not be explained here, as this wiki is intended for first time setups, and all NZTivo users should be on version 3.0 (release 1.3).
This CD iso image is bootable and supports disks over 137 Gb. See further on if your HDD is from an original TiVo, or is 40Gb and smaller.

Use CD Creation software to burn the .iso image to a new blank CD-R.
[www.nero.com Nero] lists this as 'Burn Disc from Image' - or something to that effect. When opening the image to burn, you may need to change the image type it's looking for to .ISO

Connect HDD to PC
After shutting down your PC, connect your (preferably new or formatted) HDD to your PC. It's preferable to only have the new Tivo disk and your CD-ROM connected.
Connect your CD-ROM as primary master drive and the new HDD as the secondary master. If you are struggling, or need more detailed instructions follow the Hinsdale How To.
Insert the CD that you created in the previous step into the CDROM (you may have to go into the BIOS settings and choose CDROM as the first boot device) and restart your PC, your PC should ask you to boot from CD once it's detected that it's bootable.
Press enter at the "boot:" prompt
The recommended restore command is (assuming hdr112 is the image name and /dev/hdc is the device name of the new HDD): mfsrestore -s127 -r4 -xzpi /cdrom/hdr112.30.oztivo_emulator.release1.3 /dev/hdc You may need to change the last '/dev/hdc' to '/dev/hdb' for it to work. You can determine what device drive your HDD is located at by typing: dmesg | more Scroll thru to find where your drives are referenced. eg hde: st380021A, ATA DISK drive
hdf: Maxtor 96147H8, ATA DISK drive
hdg: PIONEER DVD-RW DVR-104, ATAPI CD/DVD-ROM drive

Here you can see I have drives on designations hde,hdf, and hdg. Now figure out which is the drive your going to use for Tivo. You may only have the HDD and the CD-ROM if you've unplugged your normal PC HDD. Also make a note of your CDROM drive designation.
To save typing you can just press the TAB key after typing the /cdrom/hdr part of the command above, Linux will complete the long file name for you! Note the instructions on the CD have some spaces that shouldn't be there in this command and the beginning of the line is missing. Note: If you are restoring in an image to an original TiVo drive (eg to a 40GB drive or smaller) then you should NOT use the "-s127" option in the restore command. If you do, the restore command will tell you that the drive is too small. You can find the exact name of the image you have by typing /# cd cdrom /cdrom# ls You'll get something back that looks like this Autorun.inf*
hdr112.30.oztivo_emulator.release1.turbonet
isolinux/
kernels/
ptstart.exe*
/cdrom# See the Hinsdale How To for help with mfstools.
The backup image has a custom kernel with LBA48 support. This means you can use hard drives larger than 137GB. If you have a maxtor drive, refer to [1] for ways to stop Tivo locking the drive (should be done.
Once thats done type poweroff and wait for it to shutdown. Then take out your drive and install it into your Tivo. Note: If the Tivo doesn't boot (all you get is the bootup Tivo image) you could have a byte-swapped drive. (A 200Gb Seagate in my case) In this case use: (spot the extra -b) mfsrestore -b -s127 -r4 -xzpi /cdrom/hdr112.30.oztivo_emulator.release1.3 /dev/hdc

Setting up a Larger Swap Partition

If you use a large drive then it is recommended to set your swap partition to a bigger size. However, the default size of 127MB is not going to stop your Tivo from working. If you use a 200Gig Drive, and you find that the menus are slowing down or the remote is taking it's time to respond, make the swap partition 256MB instead and make sure you format it using the below commands. The following section is suitable for people with technical nous, so if it doesn't make any sense to you, no sweat - just skip it!
Larger swap partitions are created during mfsrestore with the -s option. The largest value for swap supported by mfsrestore is 511. For example:

mfsrestore -s511 -r4 -xzpi /cdrom/hdr112.30.oztivo_emulator.release1.xxx /dev/hdc

(or -s256 for 256Mb)

Any partitions you create over 127MB, Tivo will not be able to automagically format it. All is well though, the Tivo will boot without a swap partition. On your first boot, you can create the swap partition and mount it with the following Tivo command-line commands. After it is created, the Tivo will find it and mount it on every boot thereafter.

Note: You execute the following commands AFTER you've run the mfsrestore command, removed the new Tivo HDD from the PC, and installed it in the Tivo. Run these commands during a telnet session (if you are using a Turbonet or Airnet card) or terminal session (if you are using a serial cable) AFTER you have installed the Hard Drive in the Tivo and during or after guided setup, Not during the mfsrestore to the hard drive on the PC.
Formatting the Swap partition command:

mkswap -v1 /dev/hda8 swapon -a
swapon -a

Installing your Hard Disk in the Tivo

Not much to this step, just use the mounting bracket and make sure that if you modified the jumper pin setting on your HD that it is set as Master and not slave or you will pull your hair out trying to figure out why it doesn't work.
See Eklectic System's (eksys) How To on replacing a Tivo HDD, and skip down to where the new HDD is added. HDD Replace
Oh, also note that your Tivo might come with the screws on the back screwed in. They're tamperproof screws so they're kind of difficult to unscrew without the correct screwdriver ( Torx T-10) but if you have a flat head screwdriver of the right diameter then you can do manage it, otherwise if you really can't do it take your Tivo to your local TV repair shop and they'll almost certainly do it for free.

To do -> adding a second drive
