The big thing with these drives is supposedly they don't need fans to stay cool enough to keep the drive alive.

All I can say is the drive was always warm when I ran it.

Then one day it just never spun up. The blue light on front came on but the lack of any vibration and heat makes me fairly certain the drive is no longer spinning. Needless to say windows won't recognize it and so far there is no way to get data off it.

Seems to me the spin motor overheated and is now dead.

Customer service from Acomdata requires you to fill out large form and register and then you get message you will get an email within 3 days - great.

I guess I'll wait for them for suggestions before I open the thing and see if I can get the drive inside the box to spin by manually giving the hub a spin or find a heat circuit breaker to trip (PLEASE BE ONE).

Nothing to lose at this point I guess.

750 GB of data gone.
Next time I 'll get a drive with a fan.

Or if I do get one of these I'll just take the drive out of the case and put it in my desktop box where it will get some air and be a regular internal drive.

Oh, the other pain about this is they partition a piece of the drive as an un repartionable cd area where they store a bunch of software that they want you to install like firefox, google stuff ext. I already had them so it was annoying that this always popped up . It also takes up a drive letter for the cdrom partition as a cdrom.
And of course you lose a few hundred megs of space to this annoying extra partition.

I bought the 750GB version of this drive and it worked OK for a several months (but less than a year) as a backup drive. However, I discovered that the encryption unlocking software didn't work after upgrading my Mac to OS X 10.5 Leopard. No biggie: I just disabled the password protection while one of my computers was booted under 10.4 Tiger. I have visited the Acomdata website on numerous occasions and have never seen an update to address this issue. I also threw the Acomdata enclosure in the trash.

About a week ago, the drive stopped communicating. System Profiler only recognized the drive as a USB device if I put pressure on the connector into the drive a certain way. I opened the case, reseated the connector to the hard drive, and tried powering it up. The hard drive was making some very weak noises, so I thought that the drive itself was dead.

Not willing to give up a 750 GB drive without a fight, I went down to a local electronics place and found an inexpensive ($10) SATA hard drive enclosure. I installed the hard drive in it and, lo and behold, it was recognized but the Mac couldn't find a filesystem, which means I lost all my backup data. At least at that point I knew that the problem was with the USB interface electronics in the enclosure. I reformatted and made new backups of everything. I also threw the Acomdata enclosure in the trash.

I'm guessing that the formatting problem is due to the need to encrypt the data on the drive even though password protection was disabled. This would allow it to be re-enabled without having to re-encrypt the data. It also means that the drive would likely be unreadable in any enclosure but the one it came in.

Therefore, my advice would be to avoid this drive or any other drive that supports encryption.

Bought this external Acomdata 500GB hard drive recently. Windows starts giving me "delayed write failure" errors - not even the 2nd day I owned it. So I Google, find out that one cause of this is bad or loose cabling. I check the drive, and sure enough there is a ton of play on the cable - its loose enough that it can probably move on its own just from vibrations on my desk. I try another cable I had from another drive, and its loose too. The USB connector on the drive is not tight enough. Where is the quality control here? Am going to return it ASAP.

I literally had this drive replaced 4 times and each one died within a year. the fourth time around i never even bothered to plug it in because i knew if i used it all my data would get lost again.

So after a few months of sitting in the box i broke it out to use it for a $2,000 video editing job im working on. I figured it would last at least two months or so to complete the project. I was wrong - this thing just died on me for the fourth time - Ive NEVER written a review on amazon, but this is literally the most unstable, unusable, unreliable external drive you can buy on the market. DO NOT BUY THIS IF YOU VALUE YOUR DATA - this has cost me my thesis project the first time it died, 350 gb of movies the second time it died, countless hours of troubleshooting and data recovery attempts (all unsuccessful,) and now is costing me a little over $2000 dollars and about 36 hours of time archiving and clipping 12 hours of footage.

Is this in order for some kind of class action lawsuit or something? This drive is really really horrible. I'm not even sending it back for a replacement - I would really rather let someone kick me in the nads before I attempt to use another acomdata product. Thanks to them I do not trust any external storage devices at all anymore.
