The 120gb drive in my R10 (upgraded several years ago) has been acting up. Lots of pixelation and a freezing now and again. I'm using the Hinsdale instructions to replace it with a 250GB drive. How long should I expect dd to take when using option #3 "Copying TiVo drive to new upgrade drive". dd if=<old drive> of=<new drive> bs=1024k produced errors after about an hour so I added the "conv=noerror,sync" option. That ran overnight, about 11 hours. It reported a couple of errors it was presumably skipping over but didn't finish. Did i jump the gun? How long should I let it go?
