Re: Should I trust SMART monitoring tools or the Linux kernel drivers?
[35223.216654] usb 1-8: device descriptor read/8, error -110 [35226.942174] usb 1-8: device descriptor read/8, error -71 ~ I have read it happens as a protective measure when its interfacing circuitry notices that the USB cable does not provide enough power Looks like the problem is in the communication between the drive's enclosure and your computer. The drive is probably just fine. Hm.. I'm not sure whether SMART applies to USB devices, but I could well be wrong here. Depends on the USB-SATA bridge used in the enclosure. Some support SMART and some part of hdparm as well (e.g. set timeout for spin-down); the only problem is that it's terribly difficult to know which ones do and which ones don't, without actually buying them and trying them out, because such details are basically never documented.

Or, can I still use it with extra case and occasionally? If it is a case of lack of power, then the drive itself is probably quite healthy, which means that any problems will be higher up in the stack, e.g. filesystem integrity. To make better use of it, perhaps there's a different USB port that can be used? Some (few?) BIOSes also have settings for how much power to supply via USB - it's worth having a quick look. ~ thanks, lbrtchx Wow. No offence, but your name is better than most passwords where I work!

It depends to the USB controllers and drivers, the HDDs connected to the USB controllers record SMART data, but usually there's no possibility to get the data, but it's said that SMART by USB does work for some devices. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
