I'm using sata to usb interface to extract data and to work with end user hard drives connected to a laptop.
I'm using that for a periodic offline backups to HDD and an SSD (I know unreliable but that is the best I have for now). What I do today when I need to shutdown it are the next steps : unmount everything sync sdpram -S 30 /dev/sdX (I'm not sure if does anything honestly) Wait for ~20 minutes physically touch the disk if I feel any movement , if not unplug the power the usb cord and then unplug the power plug. I have both SSD and plain old HDDs plugged this way. I'm feeling that I'm working in an unsafe manner, does any of you have a better suggestion how to shutdown the devices correctly to prolong the disk life ? _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
