My two Cavalry 750's are both USB 2.0 interfaces and have performed flawlessly. I haven't tried any of the multi-interface drives, so I can't speak to their reliability with the 622 or 722.
I use a FAP 750 and it has eSATA and USB 2.0 interfaces.
I thought I'd read that DN did not support or recommend enclosures with multiple drives as only 1 of the drives would be used. Maybe I'm just misremembering something.
For those of you with Seagate drives that go to sleep, do you just unplug it and plug it back in every time you want to get it out of sleep mode? I have too many hours of programming on there to move it all back to the 722 and then hook it up to my PC and run the Seagate software on it to stop the sleep mode. Just seems like a big hassle.
Also, isn't there a limit to the number of times content can be moved back and forth from the receiver to the hard drive and vice versa? What about the number of times I can move the hard drive (with content on it) from one receiver to the other?
Have a WD MY BOOK ESSENTIAL 750gb. Because of problems with adding additional programs to it, moved all it's contents to another 750gb. Now I want to reformat it. Hook drive to PC but does not show under "MY COMPUTER". Tried to use WD FAT32 FORMATTER but get 'drive size is too small or not supported'. Anyone know how to format this drive? I don't trust the current contents and need to start from scratch.
