Hi,

 Let me both answer and extend this question.

I too have a 10-250 and upgraded it via pvt and instant cake and it's worked well for a long while.

 My standard def tivo's drives are failing so I decided replace that with another 10-250.

I paid for and downloaded the newest versions of the software:

InstantCakeHD 6.3d Standard  and PTVnetHD 6.3x and I've got a failure state during install.

I've reburned the iso, tried a different drive, and yes the drives are configured correctly.

during the uncompress and restore portion of the script, Instant Cake gets stuck the Starting restore process

Uncompressed backup size: 1033megabytes

Restoring 10 pf 1033 megabytes. I've let it run for 24 hours but it keeps trying to decompress the same set of files forever.

 Looks like a bad iso to me.
