[How to retrieve a USB stick to its original capacity?]

As an extension to Dfds' reply, you can perform the format with Diskpart.

 

Diskpart

list disk

select disk #

clean

create partition primary

active

format fs=ntfs quick

assign

exit

 

Alternatively since running the clean command you can go run diskmgmt.msc from the start menu or run prompt and you may be able to format it in there.

Sorry I am a newbie to Xpenology....

 

I tried to search for the vendor file in the boot usb, but windows cannot read from the usb drive (require to format it first)...

Also I tried WinSCP to log into my system as root, but it keep on fail to start the session....(I can log into the Diskstation through admin account...)

 

Appreciate if there are any method for me to obtain the vendor file and modify it....many thanks!

 

Install a program called Ext2Fsd (presumably on Windows?) and that will let you be able to mount the drive properly and view the contents.
