Acer Aspire ZG5 - SMART Capabilty?

Follow
Ben Bolton

I note that another question has already been posted about this query. I can boot from USB and everything runs fine. When I try to install using the GUI it fails. Using the CLI it does a full diagnostic test and eventually tells me the following

Device Model: P-SSD1800
Serial No:. 0208 etc
Firmware version: Ver2.YOC
User Capacity: 8,069,677,056 bytes [8.06 GB]
Sector Size: 512 bytes logical/physical
Device is : Not in smartctl database [for detail use: -P showall]
ATA version is: 5
ATA Standard is: Exact ATA specification draft version not indicated
Local Time is: ..
SMART support is: Unavailable - device lacks SMART capability
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options

Can you please advise what else I can try to acheive an install to the SSD?
I am not a coder but can accurately type inany script you can offer.
Thanks

ATA Version is: 5

    This is unsupported, but for what it's worth it looks like the SMART check is part of the official ChromeOS installation stack.

    The file in question is /usr/sbin/chromeos-install, which is a shell script that gets called during installation. On the machine I'm looking at there are a few calls to smartctl on line 407. You may be able to add -T permissive somewhere there to get it to pass the check.

    Of course keep in mind that modifying the installer stack can obviously break things and cause unforeseen bugs, so hack at your own risk!

    Good luck

    Supplementary to the question - I have looked up SMART and note that it refers to a technology that applies to HDDs. Probably not appicable to SSDs and therefore not in the ZG5. Is there a work-around? Does your software look for this technology? It would appear that it does. Can the install be amended to allow installation to an SSD. Thanks

    Hi Ben, did you try doing the install while logged out? There's a known bug that will not let the install occur when you are logged in. Try that and report back!

    I was logged out on all attempts. I also tried the install several times, shutting down and re-booting. Same result. I am using an 8gb USB stick. The OS runs fine from the stick. I wondered if the piece of the message that says ""To continue, add one or more '-T permissive' options is of any relevance. Does this indicate a way of bypassing the SMART problem?
