Its now appeared, after a couple of re-boots.
Some log entries have dates of 1971.
Will do fixdisk once massive file copy completes.
What i am doing is copying all the T2 recordings to the FVP-5000. Its a bit cumbersome, as have to go via a 128gb pen drive, so I first compressed everything - decrypt, shrink, detectads/crop, which has taken a couple of days.
I now see that T2 can be visible as a network drive on the FVP, so could just transfer from the dodgy T2.
