It'll just be similar. I seriously doubt that SMART can show cached data, somehow. I've only ever seen it produce data that's come *from* a drive, there and then. Try asking it to poll a non-existent hard drive (e.g. sdb), and you'll see what happens. There can be a lot of scary looking numbers in the data, and you can also get a bad new drive. If you have bad cooling, that's bad for drives. If your cabling is mangled, that can produce data errors (SATA cabling should never be folded or kinked, if you need to get it out of the way of things, use gentle loops). > 9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 2614 Shows the drive has been on for 2,614 hours. That would be 109 days, if it had been left on permanently. If your computer is only on a fraction of the day, do a bit of math to see if it fits your expectation. > Also, the output is basically the same whether the smartctl parameter > is "sda", "sda3", or "sd?". SMART data is for the whole drive. -- [tim@localhost ~]$ uname -rsvp Linux 4.14.13-200.fc26.x86_64 #1 SMP Thu Jan 11 05:43:34 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
