2 same usb drive problem #51

Hello,

I'm coming to you because of an issue. I have to Sabrent USB to Data cables, and both are capable of SMART. The problem is, on one of them, I have to execute the smartctl with the parameters "-s on" to read the informations. The 2 drives mounts like this : /dev/disk1 /dev/disk2

It's always disk2 which does that. Any reason for this ?

Thanks in advance !

Have you tested different drives on each of the cables? Some drives, including some models shipped by Apple, won’t return SMART data unless you first use "-s on", even when connected directly via SATA. That’s up to the drive firmware.

Best, Chris
