Query: Failed during initial format, I don't trust this product line :-(

I was really enthused about this drive. However, the lack of a physical on/off power switch seemed a little bizarre when I took it out of the packaging. It came up FAT32 and I wanted compressed NTFS so I fired up disk management under Windows and started up the format. At about 5% the format "finished", it said the drive was RAW but there really wasn't a drive there. The blue lights were on. I went to re-format it and it wouldn't format. I tried to activate the partition and Windows said "unexpected error", please restart. I plugged it into another computer and it wouldn't recognize it as a hard drive. I power cycled the first machine, plugged it in, no blue light, doesn't recognize it as a hard drive. I am returning this and will not trust my data to any Western Digital "My Book" product. Good concept, very flawed execution. Don't trust your data to this product line.
