No, you don't have to hack it first. In fact, it is probably best not to hack the original drive. Do your backup (to the new drive) and put the 40GB up in a safe place.

Or can i just install a 6.2 img on the 250 hd and hack that ?

If you have a good image already, and don't have any recordings from the old drive you need to save, you can just install the image to the new drive. If you blow the hacks and the machine won't boot or something, you can always start over.

How do you mount a unformat NEW drive ?

If you mean software mount, you don't need to mount it. You will need to install it on one of your IDE connections in your PC, and use a bootable, tivo-friendly linux CD to extract the image and place it on the new drive. Since you want to use a 250GB drive (which is over 137GB) you'll also want to make sure your boot CD is LBA48 aware. I think the PTV boot CD is popular for that.


Once the image is on the new hard drive, the linux OS running on your tivo-friendly boot CD should be able to mount the root and /var partitions.

I suggest letting the system call in and upgrade the present drive to 6.2. Then use mfs tools to copy the upgraded drive to the new drive, then hack the 250 Gig drive. This gives the optimal results.

You can purchase an image for your system from PTVupgrade, however, this does cost $20. You might be able to download an image off eMule, but that will likely take longer than forcing a call and taking the upgrade.

You can't mount an unformatted drive; mfs tools will take care of the formatting for you.

Suggestion: If you haven't done so yet, read the stickies in the Newbie forum.

I just wanted to point out: the PTV boot CD (http://www.ptvupgrade.com/products/software/lba48/lba_4.02_license.html) is free.
The PTV CD with killhdinitrd kernels (enhancements) is $5.
The PTV "Instant Cake" with a TiVo system software image is around $20. You need to pick the correct version for your model TiVo. Useful if you blow up your original TiVo drive and don't have a backup image.
The PTV "Universal TiVo Upgrade" CD or whatever they call it has some tools already on it for $20 but to me that seems overpriced.

Be wary of the basic MFSTOOLS2.0 disk which was popular on Hinsdale's Guide, because its not LBA48 aware and won't setup your entire 250GB properly.

how many hours does a 250gb hd hold. I did a backup and restore

mfsbackup -Tao - /dev/hdc | mfsrestore -s 127 -xzpi - /dev/hda

and came back with 147 hours is that right for a 250 gb

No, it should be closer to 270 hours or so. It looks like you didn't use an LBA48 boot CD to do your work.


mfsbackup -Tao - /dev/hdc | mfsrestore -s 127 -xzpi - /dev/hda

First, I'd start over and do the basic backup without the expand (i.e. leave out the 'x' in -xzpi). Then make sure you boot from an LBA48 boot disk and use mfsadd to expand the drive. You might also need to use the -r 3 or -r 4 option to increase the allocation-size of the new MFS partition.
