If Western DIgital is reading this, this problem makes this drive virtually USELESS for what I am using it for in a commercial environment. And to think I was recommending these to other people, no longer can I do that in good conscience.
We use them for backup and primary, mobile data storage. So for instance, I use mine to back up a bunch of data from my workstation, but also as the PRIMARY storage of my Virtual Machines for VMWare for software development and testing. When programs are open against the drive, it *CANNOT* go away, or data corruption and loss could ensue. I have had to begin backing my MyBook up to my workstation frequently to be safe! (PS: The lack of SMART data through the e-SATA connector is also a significant limitation for us as well, we’ve had a couple of hard drive failures and would like a heads-up that trouble is brewing and move the data to a replacement drive *before* data loss occurs.)
I have the same problem and I’m running a Dell with Intel chipset and drivers, so it’s a hardware issue within the board on the MyBook. The box goes to sleep and won’t wake up the board or perhaps the "green drive’ that is inside. What I noted was that the led’s were completely dark, Windows XP was complaining about delayed write fail and when I dropped to a command prompt and did a DIR, the led’s came on, but the drive did NOT spin up. I got cached data and that was it. As said above, I had to power cycle the MyBook to get the drive to spin up, then everything was fine.
This is incredibly annoying, as I can’t leave a VMWare Virtual Machine open over night, as if they are idle, then everything crashes down because the drive goes to sleep. I guess until there is a fix (doubtful), I’ll have to resort to a scheduled “poke” like touch or repeatedly over-writing a dummy file on the drive. I’m not sure how long it takes to go from idle to “active sleep” to “deep sleep” however.
Perhaps swapping the “green drive” for a non “green drive” would alleviate the problem.
