For some odd reason, USB drive connectivity would stop working on WD HD TV Live. The USB light would no longer turn on, but the portal drive is powered-up but without access. I would try several USB Drives and they would all not work anymore.
I would have to do a factory restore for it to work again. All the drives are Western Digital Passports. I have two WD HD TV Live and it’s happening on both.
I’ve run into the same problem. I’ve had my player for less than a week. Worked fine until today, when it suddenly just stopped recognizing my USB portable hard drive (Memorex UltraTravelDrive, 150GB) in either port. I found it would start seeing it again only after I reset the device to factory settings.
I tried a different hard drive and I tried switching out the USB cable and neither made a difference, so it’s clearly an issue with the player. Eventually, I figured out that it was being caused by one particular AVI file on the hard drive, which I assume was somehow corrupted (though it played fine on my computer). Every time I tried to play it on WDTV, it would freeze and I’d have to power off the player. When I powered it back on, it wouldn’t recognize any drive until I did a reset.
