Where did it come from? What kind of PVR was this? Anything linux-based will be restricted to at max page-sized blocks, so if it is 32k blocks you can't mount it on an x86. > I've managed to copy the entire old drive (80gb) to a correctly-formatted > new drive (160gb) using dd, and then restored the partition table correctly > (again with dd).

Don't confuse a partition resizer w/ a filesystem resizer, they are 2 different steps. You can use your favorite partition resizer (parted, fdisk) w/o trouble, I'd think; it won't care what the data within the partition is. So just move the end of your partition out to 160G. At that point I'd think you could do an offline resize; you can't do it online because a 4k-page linux box won't mount a 32k-block ext* filesystem, but the offline variant *should* be able to I'd think. BUT - if this is a TiVO, I'd go look for the various utilities & howtos which have been published about how to do this, and not try to roll your own procedure. -Eric > Any help would be much appreciated. > > David > > _______________________________________________ > Ext3-users mailing list > Ext3-users@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/ext3-users _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
