A friend loaned me an external USB3 hard drive of 4 TB to copy files. However, the drive switches to power saving mode even if file transfers are active every 100 GB, which will damage all transfers in flight and makes copying complicated (I am not on the to sit next to my computer for hours). Go, disassemble the drive, put it back in, copy 200GB more, etc.).
Obviously, smartctl / hdparm does not work because usb3 does not send the commands sent using them.
So, how to disable this "feature" so that I can simply configure it to copy 4TB and leave it alone until it's done? This is not my USB3 controller, because other large external drives do not enter power save mode when in active use. Thank you!
