I'm using WD My Book 250gb. I took it off my PC and erased what little I had on it. Formated first time with no problem. First time out I tried to download to it from my 622 with several HD movies including King Kong, War of the Worlds, Harry Potter, Star Wars and maybe one other.
Screen showed I had 239 gigs of storage and my downloads would use about 53. Time to download the selections was estimated at 3 hours and some odd minutes but a few moments later it showed 2 hours 47 minutes.
I went to check on it after about 20 minutes and the green status bar was gone and no estimated time to download completion was showing. The WD was humming along, however, so I let it be.
The next check was about 1/2 hour later and sure enough, I have the green bar and time remaining up again. Just checked a second ago and back again with no status bar and no time shown. However, it is still showing the selections are being downloaded and the external hard drive is still working.
The status bar and time are very important. They should not come and go during a download no matter how long. E* will have to address this issue.
