Question Toshiba MG07 14TB not detected at power up but fine at reboot

[youpii42]

Hello

I tried adding a Toshiba MG07 14TB (MG07ACA14TE) to my home linux server (Intel i3-8100+Asrock Z390M-mITX/AC+BIOS 4.30) and it's not detected by the bios at powerup.
In Centos 8.4, it's not listed by lsblk even when using the rescan-scsi-bus.sh script.
But all is fine (in the bios and in centos) with a soft reboot.
I suspect some kind of timeout during the powerup phase but Fastboot is already disabled in the Bios.

Anything else I can do ?

Change the port it's connected to and the SATA cable.

Thanks but I already did:
It's now on sata-0 and I tried swapping all (data&power) with sata-5 that works fine with another drive but it was still the same

Is this helpful? http://faq.areca.com.tw/index.php?action=artikel&cat=36&id=856&artlang=en

From that PDF: https://storage.toshiba.com/docs/enterprise-hdd-documents/ehdd-mg07aca-product-manual_r2.pdf



Check the 12V and 5V reading in your BIOS. Maybe the PSU is delivering more than the drive can tolerate at startup. How old is your PSU?

You can also try using a different SATA power connector from a different cable from the PSU.

Again from that PDF:

[11] Make sure the value is not less than -0.3V DC (less than -0.6V, 0.1ms) when turning on or off the power.

Maybe the PSU is providing less than 4.7V upon PC hard boot? What is your PSU brand/model?

PSU is Seasonic G360 (SSR-360GP) 80 plus Gold
Bios readings seem fine

• 12V : 12.196V
• 5V: 5.086V
• 3.3V: 3.456V

I also tried with all the other HDDs unplugged with the same result: Toshiba MG07 14TB (MG07ACA14TE) not detected at power up but fine after a soft reset.

I tried swapping PSU with a larger Seasonic Prime Ultra 850 Titanium (SSR-850TR) and it still was the same.

Last test was to use both PSUs:
Prime850 for Mainboard only
G360 for the Toshiba HDD only
G360&HDD was powered on a few seconds before the Prime850&Mainboard
With that combo, power sequence was fine, with the HDD detected in linux.

So I guess the MB boots too fast for the HDD to be properly detected during the power on sequence

Or maybe it's just that particular drive being a lemon?

It's an enterprise drive and servers are slow to boot. Guess they didn't account for people using it in desktops.

And servers usually have aic's that are slow to boot as well.

Thank you all for the advices.
I'll swap the HDD for a "non enterprise" one

just a dumb question but is it set @ 4k or 512e?

MG07ACA14TE is 512e. Why would it matter for BIOS detection ?

Try playing with you bios settings.
Disable "quick post" or similar. Some bios have a delay in seconds you can set.
If you are still unable to fix the issue i'd suggest contacting customer support for your motherboard and/or toshiba.

Does you bios have a boot override list ? is it detected inside the bios with that ?
