Thanks, Rock, for your advice (April 11, 5.47PM)
Booted Knx. CD; in console typed:
"sudo tune2fs -j /dev/hda7". Reply was about 4 lines which said nothing about ext3, so I swore for a while.
I then exited the CD, then booted the HDrive, opened cfdisk, and the filetype showing for hda7 was ext3 !
Jubilation ! That's for sure, right ?
-----------------------------------------
Think tomorrow, following Stephen's advice already given, I can get /home to move to hda7.
Thanks again,
Chada
