Hello.
I've recently purchased an Asus Rog Strix Arion NVMe enclosure:
In it I've placed a 1TB Samsung PM9A1 NVMe drive . This drive is mostly an OEM Samsung 980 Pro from what I could gather online.
The drive is in good working order as I've just taken it out of my laptop after I've replaced it with a 2TB 980 Pro.
The issue happens when I try to use it on a Zenbook Pro Duo UX582HS 11th gen i9 cpu.
This machine has 1 USB 3.2 Gen 2 USB-A port and 2 Thunderbolt 3 USB-C ports.
www.asus.com
The enclosure connects just fine to the Thunderbolt ports using a USB-C to USB-C cable. Windows recognizes the drive and shows all the partitions but with a yellow exclamation mark in "This PC".
The exclamation mark seems to be related to Bitlocker, something about the drive being encrypted but with publicly available keys on the drive.
Note: The yellow exclamation marks are not in Device Manager, but in "This PC", on each of the partitions on the eclosed drive.
Anyway, I can copy files to/from the enclosed drive just fine with a maximum speed of almost 800mb/s, but the issue is that this only works for a few minutes.
After these few minutes - which can be 5 up to 15 or so - I hear the windows ding sound that tells me a device has been disconnected. Then it dings again and the device connects again.
In the meantime I get a popup saying that:
"An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem.
Error 0x800701b1: A device which does not exist was specified
[Details about the file that was being copied when the transfer failed]
3 buttons: Try again, Skip, Cancel"
If I click Try again it starts working again, but this time for just 1-2 minutes or even for a few seconds.
After I do this few times, "Try again" stops working, meaning that no matter how many times I click it, the popup just comes back.
At this point, the enclosure keeps connecting and disconnecting continuously, I can hear a ding every few seconds.
Also when this starts happening, the enclosure appears and dissapears from Device Manager, and when it appears it stays there for 1 second or so, then it gets an exclamation mark, then it dissapeares.
Event viewer (in Windows Logs -> System) says a few things:
Warning: "{Delayed Write Failed} Windows was unable to save all the data for the file [path-to-file]. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere"
Warning: "The system failed to flush data to the transaction log. Coruuption may occur in VolumeId: G:, DeviceName: \Device\HarddiskVolume234"
Both of the above warnings refer to the source file - the one on the encosed drive.
Warning: "The IO operation at logical block address 0x21c5aec0 for Disk 1 (PDO name \Device\000001dd) was retried"
I'm using the USB-C to USB-C cable provided in the box with the Asus Arion enclosure.
I seem to have misplaced the USB-A to USB-C cable that was provided so I cannot try that one. I'll probably go and try to find such a cable at a nearby store.
However, i'm using the same cable and same enclosure on an Asus Vivobook Slate Oled:
www.asus.com
I did try the USB-A port with a USB-A to USB-C adapter in which I've put the USB-C to USB-C cable connecting to the enclosure but it does the same thing.
This machine has 2 USB-C 3.2 Gen 2 ports and the enclosure works very well on it, albeit I could only get speeds up to 600mb/s or so.
Interestingly enough, windows doesn't show the yellow exclamation marks on the partitions in "This PC" when I connect the enclosure to the Vivobook.
I've tried to connect the enclosure to a Macbook pro but no success, the macbook doesn't say anything and doesn't show the partitions anywhere. However this doesn't matter to me as I'm not looking to use the enclosure on any mac.
I've just installed windows 2-3 days ago.
Another thing to note is that I've installed all drivers provided by the manufacturer on the Zenbook Duo, including Intel RST (Managed and non-managed) when I've installed windows.
I've also installed the Intel thunderbolt drivers from the manufacturer.
Device Manager shows that on both the Zenbook and Vivobook the enclosure uses the same Microsoft driver.
The only difference in drivers is that the Vivobook does not have the Intel RST drivers installed because it doesn't need them. However the Zenbook does need them for the internal NVMe drive to work.
I've also tried disabling the USB power saving options, but I get the same result.
What could this be?
Is this USB 3.2 Gen 2 enclosure not supposed to work on Thunderbolt 3?
Thanks for reading this very long message.
