September 11, 20223 yr So I just got a USB enclosure to pre-clear and test drives before I put them in my unraid system. However, I have been unable to get it to work properly of late (the first 2-3 times I used it a month ago, I had no issues). I tried with a Samsung SSD first: Sep 11 11:51:56 Tower kernel: usb 4-2: new SuperSpeed USB device number 7 using xhci_hcd Sep 11 11:51:56 Tower kernel: usb-storage 4-2:1.0: USB Mass Storage device detected Sep 11 11:51:56 Tower kernel: usb-storage 4-2:1.0: Quirks match for vid 174c pid 55aa: 400000 Sep 11 11:51:56 Tower kernel: scsi host11: usb-storage 4-2:1.0 Sep 11 11:51:57 Tower kernel: scsi 11:0:0:0: Direct-Access ASMT ASMT105x 0 PQ: 0 ANSI: 6 Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: Attached scsi generic sg9 type 0 Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: [sdj] 937703088 512-byte logical blocks: (480 GB/447 GiB) Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: [sdj] Write Protect is off Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: [sdj] Mode Sense: 43 00 00 00 Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: [sdj] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Sep 11 11:51:57 Tower kernel: sdj: sdj1 sdj2 Sep 11 11:51:57 Tower kernel: sd 11:0:0:0: [sdj] Attached SCSI disk Sep 11 11:52:06 Tower emhttpd: device /dev/sdj problem getting id And then a different SSD: Sep 11 11:56:56 Tower kernel: usb 4-2: new SuperSpeed USB device number 8 using xhci_hcd Sep 11 11:56:56 Tower kernel: usb-storage 4-2:1.0: USB Mass Storage device detected Sep 11 11:56:56 Tower kernel: usb-storage 4-2:1.0: Quirks match for vid 174c pid 55aa: 400000 Sep 11 11:56:56 Tower kernel: scsi host11: usb-storage 4-2:1.0 Sep 11 11:56:57 Tower kernel: scsi 11:0:0:0: Direct-Access ASMT ASMT105x 0 PQ: 0 ANSI: 6 Sep 11 11:56:57 Tower kernel: sd 11:0:0:0: Attached scsi generic sg9 type 0 Sep 11 11:56:57 Tower kernel: sd 11:0:0:0: [sdj] Spinning up disk...

Again, I've used this same enclosure with different drives in the past with no issues. tower-diagnostics-20220911-1157.zip
September 11, 20223 yr Community Expert Not recommended to preclear SSDs Sep 10 04:38:50 Tower sshd[31172]: error: kex_exchange_identification: Connection closed by remote host Sep 10 04:38:50 Tower sshd[31172]: Connection closed by 100.85.179.103 port 39774 Your syslog is spammed with these, any idea what that is about? sdj doesn't seem to be connected now. Can you connect it some other way?

Can you connect it some other way? I believe that's my tailscale network ip. And I removed sdj. I can connect it through SATA but the whole point of my USB enclosure is to check disk health before I open up my server. Is there a way to make unRAID "forget" sdj?

USB is not recommended for a whole host of reasons, what you are experiencing is one of them. Not all enclosures are created equal, some work better than others. 1 hour ago, Howboys said: Is there a way to make unRAID "forget" sdj? Reboot.

This one works well for me, I use it for making backups to store offsite. Passes SMART report and everything. https://www.amazon.com/gp/product/B00LS5NFQ2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

September 12, 20223 yr Community Expert Looks like the first device was still in use when it was disconnected, hence the following problems, rebooting will fix it.

(unrelated to this issue but) I think that might have happened because preclear on USB3 ports seems to not work properly (-110 error code as you can probably see in the diagnostics I attached above). The pre-read happens for a couple of minutes at high speeds and then the device is just disconnected. Doesn't happen on USB2 so it's not the enclosure.
