USB3 Drive Base Disconnecting During Write Cycle

This is so frustrating!  If I could, I would have returned my Surface Book.  The USB is basic, nothing new, it is not unreasonable to assume that is should work perfectly!  Like you, I have the Samsung T1 that is worthless with the Surface Book.  It works flawlessly on my Lenovo and my HP.  Do you hear that MS - HP and Lenovo?

Now during the Microsoft event he shows off copying 3 GB from his USB SSD, which looks like the T1, and no issues.  Is it working for him or did he just get lucky.  I purchased my Surface Book from this presentation.  Call me the fool?

I have had the same issues.  I went through two Samsung T1 SSD's under heavy write I get the same errors in event viewer finally the entire USB bus will crash and the drives will disconnect.  As well as the Surface Dock which is just a USB 3.0 dock with Microsoft's specific connector.  It has to be either a firmware or software updated need.  It seems the be across the board.

Looks like a mod mover my original question into that thread.  My issue might be related to this one here but I'm not 100% sure of it.

Mine does not happen on heavy writes... it just happens all the time.  It seems to be related to UASP.

Hi,

Looks like my Surface Book is having issues with writing to my UASP(USB Attached SCSI) External disk enclosure.  I run a ICYRaid MB662U3-2S R1 enclosure with 2 disks in Raid 1.   When I try to write on the disk, it will sort of start but then will hang forever.

The Task manager show the drive has having 100% wait time

In the event log, I get the following :

Reset to device, \Device\RaidPort4, was issued.

The IO operation at logical block address 0x5a9448 for Disk 1 (PDO name: \Device\0000011f) was retried.

The external drive enclosure works A1 on my other laptop, running in UASP mode under Windows 8.1.  Also works A1 on my Desktop, also running Windows 8.1.  I'm now upgrading my desktop to Windows 10 to see if I could replicate the issue.

I'm pretty sure UASP is the cause because it will hang on all the ports (including those on the dock) but adding a USB 2 hub to my surface and connecting the drive though it (disabling UASP) fixes the problem (but I get terrible performance)

You're lucky you were able to return it. I was just told that since there is no fix right now I'll have to wait to see if a firmware update solves it (Microsoft Store Employee)

Has anyone tried a different OS to see if that has an issue?

I did a bunch of testing with my Book (I7, 16GB, 512GB) before returning it and am convinced it is not USB power related. Also, I had files get corrupted when writing them to the external drives individually or as part of a large transfer, whether connected directly or via a dock.

I would NOT use this for any data you care about. I returned my Book and will wait until I know that MS has addressed this. There have been multiple reports of the same issue.

Here are the tests or incidences I have experienced:

Corrupted Word file when saving to external storage.

Corrupted pictures when transferring from internal storage to external storage.

Disconnected external storage during large file transfers. (I also had intermittent disconnects with smaller file transfers and believe it is not related to the total size of a transfer, just that a large transfer is more likely to fail)

This was with external SSD and external My Passport connected directly to Book or via external Targus Dock (powered). They both work perfectly, all of the time when connected to a Lenova Yoga 2 Pro via USB3 directly or via the Targus Dock.

If you have seen me post this before, I apologize, but I believe it is important for buyers to be aware that there appears to be a problem on at least some of the Books when using external drives. Too much to lose!

That said, there are others that have our configuration that have tested this and have not seen this problem. Mine was from the same lot as yours.
