This is the epilogue to the USB3 problems that I had with my Dell XPS17 L701X and the Iomega 500gig USB3 drive.
I had all the symptoms described by many in this forum. I spent many hours talking to Dell technical people. We tried many avenues to no avail. I was very frustrated and got a return authorization number for my laptop and I intended to pack everything back to Dell after Xmas.
Then I had a doubt because many years ago, with my old Dell Inspiron under XP, I had a western Digital USB2 that gave me a lot of trouble. I circumvented it by discarding it and buying a SeaGate and everything went fine. Consequently, I decided that before returning my Dell XPS, I had to try the new Verbatim 750gig USB3 drive model SNG750GB from Amazon with express delivery. I plugged the drive and it mounted immediately. I noticed a flash installation of something by the drive. Since then, the Verbatim USB3 works like a charm. ZERO USB3 problems. I transferred 700 gig of data, cloned the C drive, repartitioned etc.. A full night of work. The drive is still there humming along. Perfect. So far so good.
I then re plugged the Iomega USB3 drive. It mounted then after a few minutes the same problems reappeared. That Iomega 500gig USB3 drive will be returned to Dell for a refund since it is clearly the offender.
The UBS3 problem that everyone complained about is coming from the manufacturer of the USB drives, especially Iomega which is definitely not compatible with this Dell machine. It is possible, as was suggested ealier, that the chipset was too new for that Iomega drive, and this is why I took the latest Verbatim drive, hoping that some consistency would prevail. The driver is the same Renesas 126.96.36.199. My advice to those who are frustrated is to go and buy the same Verbatim 750gig drive that I did.
In retrospect, I was very frustrated, but with a cooler head I must admit that the Dell technical service was very good and clearly beyond reproach in the step by step debugging process. I cannot divulge the name of the person that helped me because of the rules of that forum. He sent me a new Iomega drive (same symptoms), sent me a new internal SSD (256 gig) just in case something was wrong with my C drive, send me a return authorization to refund me for the computer, spent several hours taking control of my machine, etc.. I can hardly fault Dell. The problem has nothing to do with Dell but the Iomega drive.
I also realize that it is fashionable to criticize Dell. That would be wrong in that instance. In fact, my bottom line is that my next machine will be a Dell because I know that if I get into trouble, I will receive a fair hearing.
I have an advice for Dell. I bought the Iomega with the laptop because Dell advertized it as part of the XPS 17 sale. That was a mistake. Dell should immediately remove any recommendation for that Iomega drive, and be more careful in the future before endorsing anything.
Hello it seems that some external HDD drives /cases/docks that contains a jmicrom chip are incompatible with the NEc Renesas usb 3.0 chip found on the XPS.
Investigate before purchasing an external HDD solution.
As explained in my previous post, I don't agree with the assumption that the controller is incompatible with some of the HDD drives because I tried this Iomego eGo 1TB 2,5" USB 3.0 hdd at the usb plugs of the samsung R510 notebook which has the same renesas usb 3.0 controller and it worked directly fine without any troubles. There might be another reason why it is especially not working on our XPS 15 notebooks. I really expect an answer from the dell techcenter otherwise they will lose their customers.
They explained to me that this is probably because of a power issue... Personally I believe that they simply cannot figure out exactly what is the matter.
Or probably that is the problem of the chip inside the laoptop. I do doubt if they dare to launch a callback of laptops.
I need an external HDD dock, but I really do not know which one to buy, I suspect that the Vantec ones are not going to work, due to the JMicron chip.
It they are not solving this issue, Then our solution right now is to test every external storage solution, and see which ones work with our laptops. Or send the notebook back if any fully functional storage solution is found.
Not necessarily because the drive tha caused me problems (and I understand as well as several others) is the iomega 500gig superspeed and NOT the 1 terabits. The controller of the different drives may not be the same.
Hence the incompatibility mentioned earlier between the drive and teh Rensas controller hardware inside the computer is so far the most plausible explanation. Dell cannot be held responsible for maintaining compatibility with all the drives on the market. The problem is that Dell did not warn the customers (i.e me for instance) of the incompatibility problems with some drives. My guess is that this will change because by now they are acutely aware of the difficulties.
I have the same problem with my new Dell XPS 15. When I connect my Iomega eGo 1TB USB 3.0 external hard drive and copy photos and videos to this new laptop’s internal hard drive – the copying process freezes and does not even respond to cancelling or closing it. After researching the problem, I found many people have the same problem that I have and it is believed that problem lies with - the Renesas USB 3.0 host control.
As many suggested, I downloaded the Renesas USB3.0 Host Controller drive from Dell website and reinstalled the drive but the problem still exists. I submitted a support request to Dell on 12/21/10 and they have not responded back to me since.
It should not take Dell more than a few days to plug in their XPS laptops with the USB 3.0 hard drives available from major brands to test and make sure they work properly – especially the Iomegar eGo USB 3.0 portable hard drive that Dell is selling to their customers.
Dell broke two performance promises when they sold their XPS laptops to their customers: the usb3.0 and the customer support – either has functioned as promised. I suspect some of the comments posted on this forum are written by Dell very own staff to excuse Dell from fault.
I read that "hvp0109" suspect that "some of the comments posted on this forum are written by Dell very own staff to excuse Dell from fault". Since I wrote something that was favorable to Dell after a long frustrating investigation on my own problem, I suppose that the comment applies to me.
I suggest that Hyp0109 Google my name "gracovetsky" and sees for himself from the thousands of hits that it is not my habit to play this kind of game. I believe my Iomega problem was solved when I threw out the drive since the best logical explanation (first suggested by Pituky but challenged by LordEdward above) was a mismatch between the Iomega drive and the Renesas controller. And again, it is not for Dell to insure compatibility with a specific manufacturer, but to insure compatibility with most of them. My solution was to buy the latest Verbatim 750 gig from Amazon. I have it for 10 days now and I am delighted.
The problem of Dell has been to recommend the Iomega ego drive. That was a bad mistake. So I suggest Hvp0109 return the Iomega drive and move on. Enough time has been lost on what is now a well know issue and a well known solution.
I have the iomega ego 500 gb drive, that I bought with the laptop which was recommended by dell. I am past the return policy, so what should I do.
Dell needs to fix this with a driver update, or this will be my last dell. Sorry I sound mean, but like the poster above said, they should test compatibility if they are going to sell them with the laptops with a discount.
