Problem mounting external USB HDD AS6204T

[huffie]

Hi all, have a couple of questions to ask with regards to connecting to external USB drive. I noticed that if an external USB drive is connected to Asustor prior power up, upon powering up Asustor will not be able to boot up (have experienced the same with AS302T). Is this normal that I have to unplug USB drive prior boot up?

Secondly, recently one of my drives (on bay 2) on AS6204T has been degraded (due to dying disk) , after removing the degraded drive I'm unable to get my USB drive mounted. Based on the log, I see this line

However, as I'm unable to access the drive I tried to do a smartctl --all /dev/sde and I got the following message

Code: Select all

/dev/sde: Unknown USB bridge [0x2537:0x1066 (0x100)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

Could it be coincidentally that the external USB dock is faulty or is it because bay 2 drive is empty resulting some issues? I'm currently awaiting the delivery of replacement HDD.

Thanks!

Hi,

For USB drive, be sure that disk in USB don't have any partition flagged as "boot partition", to avoid problem with BIOS (or EFI) that search to boot on USB before D.O.M. (for recovery)
... if boot flag partition exist, deactivate it (use parted in Linux with "flag" management option ... same tools exist on Windows for Windows partition or generic tools like Acronis disk image, etc.).

Tested on other NAS (multiple brand) never on AS6204T ...

Thanks Philippe for the suggestion, will try once I can get the Asustor to recognize my USB dock. For some reason I'm still having issues trying to mount (have replaced my degraded HDD, so now all bays are occupied).
I noticed there's this message in the log

Can anyone enlighten me on this? Thanks

Hi,

Difficult, because "Disable of device-initiated xxx failed." can occurs for lot of reasons
... initialize failed can be the result of :
... ... hardware failure (rare if device is recognize)
... ... USB2 device on USB3 or reverse due to low or high power delivered
... ... not updated firmware for the USB dock (your must be at least at : Norelsys NS1066 Sata III/USb 3.0 controller Firmware Version 2.67 (if I don't do an error))
... ... bad format ex. exfat but not supported
... ... bad partition format (ex. some NTFS build on Windows, can't be recognize) ... in this case, only a partition format done in the NAS can solve the problem.
... ... top many files or / and folder on the root USB device
... ... Linux 32 bits limit (do uname -a in a terminal) or not updated libraries for x86_64 (Asustor as lot of NAS provider keep old system libs (ex. 2.22 when 2.27 is used for same kernel level)
... ... etc.

So only a system trace can help (if it's not a "common" problem) ... please, call the support
Philippe.
