I have seen comments in the reviews that the unit "drops the drives" or "unmount the drive" during operation. What does it mean? Can I test for it?

"Unmounting" is a term from the days of TAPES, but it means that the drive is not available to write to, and it's ok to remove. In operating systems (these days) there is a "safe to remove" icon that allows USB connected items to be "unmounted" making them safe to remove. I have never had a problem with the drive being "unmounted", but I have had problems with the USB connection shutting down (turned out to be a computer problem.). I eliminated the USB problem and I have two Rosewill units (two drives each) connected 24/7. I have no problems with them. I don't know how you would "test" an unmount problem.

When in use my Mac reads that I unpluged or remover the drive without ejecting the drive first. In fact what is happening the CHEAP plastic usb housing is so lose that it slips and disconnects witch tell the computer that I unplugged it or did not eject it before ejecting it. It momentarily unmounts the quickly mounts aging,, unfortunately you lose the data you were transferring. Best to spend a few $$ and get something with a metal usb mount.

I log off and then I log in ,it's safe to eject...... other hard drives ,Seagate , WD, give message "Try again later" very rarely.

More information please: OS? Steps you have taken (I.e. Have you unplugged the drive and restarted the computer, etc.) also, was the drive bring accessed when improperly ejected?

I would say that only the manufacturer can answer your question. How would they determine if your drive failed prematurely or used up it's 80TB of writes???

Mine does not seem to disk over write once full. I recently had to erase all to free space as it appeared to have stopped recording. Since then I´ve been careful to erase once in a while and haven't let it go to full again so I don´t know if it was an isolated incident or if not over writing is the rule. For the rest, it works very well.

It is probably a software pre-installed on the drive that is telling you to do that. If you don't want to use it, format the drive before you start using.

Never had that issue with this item. try unplugging all cables and then try plugging the drive into the wall, with out any cables to the computer. If the problem persists, contact WD. Hopefully you are still under warranty, and they can get you a replacement.

I have never use the "safely remove drive from pc" function. I just unplug it, and no data is lost or corrupt. My previous drives are still working fine. It may not be the right answer but is one that has worked for years without issues

Anthoney, I need a bit more information, as to what you have done already and the results you have gottern so far and the specific things that are not working with this unit, then prehaps I can tell you what you want to know, first of all make sure that the drives are being recognized, are you trying to use this as a stand alone or with you computer??

WD says that greens will work and nothing else. I have a feeling that has to do with the lower power consumption. I have heard horror stories about green drives and WD software has said my drives have gone bad, but the drives read and write just fine. I love the raid setup and dont know why anyone else hasn't continued this setup at this price point ( I bought mine used for a little less than $100)

I have found the G Drives to be more stable. Have had some LaCies fail on me.

Send it back, it's defective. They shipped out a lot of defective ones... esp. around December for the holidays when they were on sale. I suspect while they were on sale & they were selling lots of them, they put inferior drives in them to increase their profit margin.

Yes, there must be something wrong, or a few of the disk drives are loose. I would check/reseat the disk drives with the unit powered off. If this does not fix your issue, then I would return it, or get a replacement unit.

That raises the question: What is the "proper packaging" for this drive? And the corollary question: How do you know it when you see it? What I do know is that mine has worked without a qualm since I bought it.

The unit comes with a software utility that will alert you to a problem drive. There is also a light on the front panel that indicates a drive failure and indicator lights for the individual drives. This has all worked fine for me with the exception of one drive that was damaged in such a way it hung the Mediasonic unit.

Did you turn it on? Is it fully plugged into the drive? I had an issue with an older ISA/EISA drive not getting fully plugged in. If you are using one of the 3.5" drives you need to check to verify that it is powering up. No power means it is not working. If you hear the drive power up (you can hear it spin up) and it is fully connected is it making any other sounds like clicking? If so the drive itself may be dead. There are several tricks to try if that is the case but without more details of the issue I can't help much more.

thanx for posting this.. i have no idea why, and I just bought one.. so I'm going to check my dvd/cd drive too! Also, is your drive partitioned correctly? My D drive had more gigs than C..
