Dell 5737 problem with USB3 HDD caddy

I have a Dell 5737 (Win 8.1) that came with a Samsung Momentus St1000LM024 1TB HDD.

I've installed an SSD in the laptop, and moved the HDD into a USB3/UASP enclosure (see ).

After a few minutes of sustained use (EG format partition with "quick format" disabled), I get error:-

USB device not recognized

The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.

Event Viewer lists the following:-

Event 153, disk
The IO operation at logical block address 0x1c43a800 for Disk 1 (PDO name: \Device\0000008f) was retried.
The IO operation at logical block address 0x1c43ac00 for Disk 1 (PDO name: \Device\0000008f) was retried.

Event 129, UASPStor
Reset to device, \Device\RaidPort2, was issued.
(9 occurences, 12:13:17 - 12:15:48)

Event 140, Ntfs
The system failed to flush data to the transaction log. Corruption may occur in VolumeId: \\?\Volume{3ce92d13-06cd-456b-8f19-a735f1d63ffb}, DeviceName: \Device\HarddiskVolume30.
(A device which does not exist was specified.)
(7 occurences, all 12:16:34)

The caddy has both data & power cables. I get the same errors, regardless whether the data cable is plugged into laptop's USB3 or USB2 port, the power cable is plugged into laptop's USB3 port, USB2 port or an external 2A charger for my Samsung tablet.

The caddy works perfectly well when connected to the USB3 port on my desktop PC (happily formatted a 700GB partition at 100MBps over 2+ hours). NB this is Win7.

The disk works perfectly well on the laptop when I put it in a Sharkoon Quickport USB2 adapter, on laptop's USB3 port.

I seem therefore to have eliminated:-

  • Caddy has a universal fault;
  • Disk has a fault;
  • Caddy incompatible with HDD;

I seem to be left with:-

  • Laptop is incompatible with the caddy.

Can anyone suggest any troubleshooting / settings I can adjust to make the caddy work with the Dell?

Many thanks for any help.

Cheers, Martin

Its hard to say. Does the HDD you are having issues with list the power requirements on the drive?

Have you tried the drive in another laptop vs just another desktop?

I have limited resources for some for the information I wish I had. If you select USB root hub you can see the listing of power in device manager, but I was wondering if the hub was giving power to each port separately or if was splitting power between ports. It makes me wonder if the second power USB is also working. The desktop may be overloading on USB power and giving enough power on just one USB connection, but the laptop is unable to do this, so it may be a problem with the power only usb connector. Its a long shot, but you have run through most other common problems, so whats left are the uncommon ones. 

Try connecting just one usb connection to the desktop and see if that works. 

I would also recommend switching off of RAID in Bios and going to ahci if you can. 

I would also try starting your system and going into bios. making sure the drive is registered, and then watching the drive. Let the system sit in BIOS for about ten minutes and see if the drive is still spinning up in the caddy. If it is still spinning in the caddy with the comp in BIOS, then we can safely assume it is a windows issue and need to focus there.

There are other things at play but I do not have the information handy to pinpoint. Some laptops have this issue, others dont, and there are different reasons behind it. I do external HDDs a lot, and I actually have done my own homemade caddy with a sata adapter and had things work fine, but other HDDs dont work. There are some things specific with the HDD that prevent them or are incompatible with the laptop. Like I said before, you are not the only person who has this problem. At least one other user had the same exact problem, just different Caddy.

I disabled selective suspend & re-ran. Same fail.

Also tried with power cable plugged into desktop. Again no difference (USB SS was left disabled for this test).

Whatever I do, the device seems to disconnect a few minutes (3-5) after the run starts (perhaps 4-7 mins after plugged in).

I'd find that suspicious, but what's left to turn off that might stop this from happening?

Running win 8.1.

I'll try plugging power cable into desktop USB port, but would be surprised if that can supply power better than a dedicated USB PSU. Stranger things have happened, though. Downside is that cables are very short, and I'll need to leave both laptop & caddy on the floor to achieve that, which I'm not very keen on.

I didn't have any trouble finding the power options (I was right-clicking the battery), but you said there was somewhere in Device Manager where I could list the power draw of the individual components, which would be perfect for diagnosing this issue.

Funny you should mention 500GB vs 1TB drives. I have the following caddy in my laptop. Was intending to put the 1TB drive in there, but it wasn't recognised. A 500GB drive (WD5000BEVT) works fine. (I've confirmed this isn't affecting the results with the USB caddy by removing it. No difference.)

I don't think my Dell has powershare?

Power menu is pretty much the same in Win 8.1. I presume disabling selective suspect will reduce battery life? How much of a hit do you find it to be?

Thanks again for your help.

cheers, Martin

No problem. Are you running Win 8.1 or 7?

May be slightly different steps or options. 

Also, I may recommend, on a whim, if you can arrange it, try plugging the second USB connection, the one for power, into the desktop USB and the data transfer USB into the laptop and see how it works then. 

I still believe that it is a power issue, and that the laptop is simply not sending enough power to the caddy. This can actually vary by the HDD you have included. You are also not the first person to have this issue. Other users of the same laptop have tried similar things with the same trouble you have, However, one user, as an example, put in a 500gb hard drive with different power requirements into the caddy and it worked fine, but the HDD that came out of the system before swapping to SSD, did not.

If you are having trouble modifying the power settings in the device manager, you can also modify then in the power settings. Simply right click on the battery icon in the task bar, select  "power options" then find the plan you are using and select "Change plan settings". then select "Change advanced power settings"

Then change the usb settings as shown in the disabled. 

What this essentially does is prevent Windows from putting the usb device to sleep. I often modify these settings because I use the power share port when my system is sleeping in order to charge my cell phone, tablet, or run a small fan, and various other things. It is nice feature because I can leave my laptop in my bag and plug my cell phone in to charge it, and not worry about the laptop having to be on and trying to cool itself while stuffed in a bag..which turned the bag into a furnace of sorts. 

Check out some of these options and let me know what happens. Keep in mind the screen shot is for Windows 7. I do have a windows 8.1 laptop, and the steps should pretty much be the same on it but I will double check. Aside from a few small things they did not really mess too much with the power options menu between windows versions.

That sound like just what I need, but couldn't find a power tab. Where do I find that? I did try a quick google re this, but without success.

Also, while the drive itself shows up connected to the USB3 hub in device manager, the power lead does not (windows also doesn't announce that it has been plugged in, as you'd expect).

Thanks for your continued help. Much appreciated.

cheers, Martin

I would double check the ports in device manager directly. 

  1. Go to Device Manager

  2. Click View > Devices by connection.

  3. Click on your Machine Name, hit the * to expand everything.

  4. Look through the properties of the different USB Hubs, you can see what devices are connected.

  5. On the power tab, you get to see the power a device is consuming and what is being offered.

I would also test going into power management and turning off the permission to allow windows to turn off the device. 

The errors you describe are showing that there is a drop off in response from the drive. The PC is trying to communicate but the drive is not responding. This is most often because of power issues. 

With the above method you can check just how much each port is putting out and that it is operating normally as well as not shutting off during use. 

If this does not resolve any issues, I would also recommend testing a different drive if you have one. Double check the power requirements of any drive you want to use, and then put it in and see if it works. The USB power output and management can definitely be better on a desktop than on a laptop, but you should still be able to use it on a laptop for your needs. 

I would also recommend checking BIOS and drivers to make sure everything is up to date. Always good practice to check, even if you are not having issues. 

Hope this helps

Many thanks for your response.

The caddy has two USB cables, in order to ensure sufficient power.

USB spec is for each USB socket to provide 0.5A at 5V, and the Dell should be able to manage that, at least when it's operating via the mains adapter. I forgot to mention that the Dell was mains-powered through all my tests.

Also, even if the caddy won't draw the full 2A from the Samsung adapter, there's no question it should be able to get 0.5A. And it works fine off the desktop machine, again implying any deficit of power is down to a fault with power delivery from the Dell's USB sockets.

Drive specs are 2.2w avg when reading/writing (yes, could spike higher), but the caddy will run all day with an SSD inside without even connecting up the second power-only USB cable. The SSD drive is "2W in operation" so the caddy itself is taking *much* less than 0.5A. The drive will be getting almost 5W if the Dell's USB sockets are to-spec.

I find it unlikely that the Dell can't meet specs on its USB sockets. But if that is the case, how can I configure it to make sure it does (any power saving, or whatever, that I can disable?)

Thanks again for any help.

cheers, Martin

It sounds as if you are not getting enough power to the drive. I know that HDD enclosures can be a pain, especially if there is a power issue. The enclosures usually market themselves as self contained, but depending on the HDD you connect it to and the system you connect it to, you may need more consistent power than the system is willing to provide. 

I do not know if the Samsung tablet charger will be fully compatible I would recommend contacting the seller to ask about supported power supplies.
