    I know that and of course I booted from the CD. If I type in copykern, I get:

    sh: copykern: command not found

    Which means its either not in the path, or its not on the CD. In either case, the CD is not working. Also, after booting, there are 2 shell errors before I get the PTVupgrade /# prompt.

    Oops, a problem with the CDROM automounting script... doesn't seem to work on all PC's

    Short term fix: mount -o ro -t iso9660 /dev/hdX /cdrom

    where hdX is one of the following:

    A == primary master
    B == primary slave
    C == secondary master
    D == secondary slave

    My guess is that your CDROM isn't on one of the aforementioned device ID's, correct?

    Thx,
    Lou

    My CD/DVD ROM is the secondary master, so the following did work:

    mount -o ro -t iso9660 /dev/hdc /cdrom

    There is another problem as well, you don't allow copykern to use hda. I remove all of the existing drives in my system before using this as I've had UNIX/Linux/Xenix systems destroy my DOS/Windows partions and will never allow both to reside on the same system. Was there a reason you don't allow it to work on hda, other than thats where many people keep their DOS/Windows drive?

    I also noticed that once you place the new drive into your TiVo and boot it up, the new drive will become locked. I put in a 200GB Maxtor and this happened, thus requiring the use of qunlock each time I needed to do anything to it.


    Thanks

    Will take another look at the scripts; not sure why it works on some systems, and not on others.

    As for CopyKern being hard-coded to not allow /dev/hda - our other tools require drives to be connected to secondary IDE; hence that assumption. Will try to document that better and perhaps create a different CopyKern version that allows user-selected target drives.

    That has nothing to do with the boot CD you use and everything to do with the type of TiVo you have; my guess is that you have a Sony SVR2000....

    DON'T use qunlock!

    One moment's inattention and you'll lose that nice new drive.

    DiskUtil is a safe alternative.

    Could it have something to do with the system having multiple CD/DVD drives? I have a DVD ROM and CD-RW drive on the machine I was using.

    I have a series 1 with a 160gb drive and have only utilized 137gb of it for a long time. Is there an easy way to see the other 23gb? Do I have to wipe it and start fresh?

    Maybe. If you're lucky, all you have to is boot the LBA-48 CD, mfsadd and CopyKern.

    It all depends on how many partitions you've used. There's only room for three pairs of MFS partitions on the A drive, so you can fill up the partition table pretty quickly.

    If you have an early Series 1, with an 11-partition A drive and you went straight to 137Gb, then you should have 3 spare entries in your partition table.

    However, if you have a late model, with a 13-partition A drive or you've already upgraded more than once, then you'll only have 1 spare entry, and expanding requires 2 partitions.

    mfsinfo will give you a definite answer.

    I can't get anything meaningful from mfsinfo. My drives are setup with tivo hd being primary master and the boot cd being secondary master. No other devices. This is a P4, 1.7 with a promise card installed (not using that for this). Should I be attaching these drives to the Promise card? What am I missing? The cd boots fine I just can't get anywhere.

    thanks..

    Do you see the drives being detected in the Linux boot log? (dmesg | grep hd if you miss it during boot).

    I do see that hda is the hard disk and hdb is the cdrom. I have them on the same ide cable. When I do mfsinfo /dev/hda I get this:

    mfs_large_volume_header:
    mfsvol_read_data: Success

    What am I missing?

    It's not a problem that I recognise.

    If you boot in byteswapping mode, you should see the TiVo partition table in the boot log. I don't know how byteswapping is set up on Lou's disks, but you might have to move the hard drive to hdb or use a different boot disk.

    I have noticed some strangeness with the LBA48 kernel and how certain apps interact with the filesystems on the drive; last time I checked, using things like nic_install were a problem with the LBA48 kernel. We have a different disk we use for certain apps that runs off a different kernel (we boot it with swap enabled) and that solves that problem. The universal boot cd solves both problems as its packaged with both kernels so you can boot in different modes for different requirements. Only reason its not available for free download is that its significantly bigger; trying to strip down and consolidate things so we can have one unified boot disk that works for all things; easier said than done, as it does get confusing...

    Trying to get an extra 23gb from a 120gb doesn't work I found. I forgot that I swapped the 120 and 160 a while back before there was support for 137gb + disks. My bad.

    I was still curious why the msfinfo wouldn't work with the 120gb drive. Robert's suggestion of doing the dmesg | grep hd tipped me off. It said the drive was 10mb. My bios was set to autodetect and was not seeing the 120gb drive correctly. User defined settings solved the problem.

    Sorry to have wasted your time...
