Upgrading TCD746320 to 2TB WD20EZRX Cannot Expand

Hi,



I was using JMFS v1.04 and following showthread.php?t=455968 for a TCD746320 using a WD20EZRX



The copy went well.



But expand gives: "Expand did not finish successfully"



I upgraded connected to SATA on a motherboard, but now have the new disk on a USB adapter. The USB adapter has worked for upgrading an earlier S2 Tivo to 1TB.



hdparm -i /dev/sdb gives "HDIO_GET_IDENTITY failed: Invalid argument"



hdparm -N /dev/sdb gives "HDIO_DRIVE_CMD(identify) failed: Invalid exchange



fdisk -l gives:

Disk /dev/sdb: 2000.3 GB, 2000398934016 bytes

255 heads, 63 sectors/track, 243201 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00000000

Disk /dev/sdb doesn't contain a valid partition table





And I don't want to put it into my Tivo at this point...



Any help is greatly appreciated.



Thanks,



Paul
