Acer Aspire A-315-56. Second drive SATA SSD magic.

AlexVolkoff

Hi!

System description:

Acer Aspire A-315-56 laptop

First drive: M.2 NVME SSD - Ubuntu 20.04 installed.

Second drive: SATA SSD

Situation:

After power on both drives are present in BIOS.

After Ubuntu loading only First drive present. Second drive not recognized by any disk utilites (fdisk,Gparted..) at all . In dmesg log file has next: "...ata2: SATA link down (SStatus 4 SControl 300)...."

After doing laptop sleep mode in/out (dislay panel down/up) second drive appear. But, every time I must manually mount second drive.

So, system boot sequence every time is:

1. power on

2. waiting system load

3. display panel down, enter sleep mode

4.display panel up, exit sleep mode

5. mount second drive manually

Tested with three different models of second drives. All are same.

Tested with Windows10 - no problem, second drive always present.

What is the bug with laptop? Or with Ubuntu ? Or with both?

Does it exist as a device under /dev/SD* where the * could be anything? It could be that it's just not auto-mounting on boot and the power / sleep cycle is just causing it to treat it like a removable disk

If it exists under Dev, you may be able to add it to fstab or through the GUI disk management tab to make it auto mount

" Does it exist as a device under /dev/SD* where the * could be anything? "

No, hasn't any /dev/sd* present after OS loaded (only /nvme0n1p1 present at that time), until to sleep/wakeup sequence are done.
When sleep/wakeup are done /dev/sda appeared.

Oops on the multi post aha!

If you grep for sda in dmesg what shows? info on the drive would be under that rather than sata

and try a

ls /dev/sd*

after booting but before the sleep

Hi!

Sorry for multi post.

I didn't do it on purpose.

Ok! let's go back to our sheep)

After booting but before the sleep:

1. Grep for sda in dmesg show nothing at all.

Seems, like second drive not present at all for OS before sleep/wakeup sequence will be done.

In /var/log/dmesg ata1 was present, but after " SATA link down (SStatus 1 SControl 300)" it has disappear for OS.

When we get SStatus 4, it is mean OK, and OS recognized second drive.

But SStatus4 we get after sleep/wakeup sequence only, but not after OS boot.

What is SStatus mean?

And I see one interesting thing: second drive was recognized by OS as first drive (ata1). Maybe the dog is buried right here?

UPD:

I'm found one book, named "The Essential Guide to Serial ATA and SATA Express". In that book has some explained about SStatus and SControl values.

"...

SStatus Register
The SStatus register is a 32-bit read-only register that conveys the current state of the interface and host
adapter.

...."

SStatus = 1 is mean that "Device presence detected but Phy communication not established"

SStatus = 4 is mean that "Device presence detected and Phy communication established"

"...

The SControl register is a 32-bit read-write register that provides the interface by which software con-
trols the serial ATA interface capabilities

...."

SControl = 300 is mean that "Limit speed negotiation to a rate not > Generation 2 communication rate" + "Transitions to the PARTIAL power management state disabled."

So, in our case it is mean that second drive presence detected but Phy communication not established.
