Raspberry pie 3B+

Andre,

The power supply might be 5V, but have you checked at the Pi and the HDD? Unless the lead is very short, you are probably losing at least a volt in it.

Hi R101 & cmh714,
Thanks for your posts. Didn’t give power a thought until now. It is a known issue on the 3B+, boot power peaks cause problems, this happens even when a 3B in the same configuration had no problems.
A short HDD cable is potentially a very smart and simple solution.
Lets see if we can verify/clarify what is going on. Any other suggestions are very welcome.

Hi janui:
Modifying the value of config. txt - > boot_delay = 2 < - - - 5-10 is not helpful... Sda1. device is still wrong after restart. Penultimate 1 minute 30 seconds..

PS. These problems will not happen on moode system. He can use usb-hdd to boot normally. There are no errors.

Hi janui & cmh714 & R101:
It took me a little time to test the above questions in other ways.. The USB power supply problem of PI3B & PI3B +.

I use 3.5 inch HDD - > connect SATA to USB card... 3.5 inch hard disk fully uses a separate 12V & 5V power supply!

SATA to USB Card Connecting to PI's USB Port & PI Hardware Supplied by Another 5V/4 Amp Power Supply

This method can completely eliminate the impact of power supply shortage.

Unfortunately.. RUNE will still prompt sda1. devie to wait 1:30 seconds in the boot process.

PS. Hard disk boot in Rune 0.3bata + PI3B environment. There is no such problem!

Testing these faults over and over again is time-consuming and very hard. Please give more praise to the rune team for their hard work.

Look forward to Janui reviewing the logs of sda1 & sda2...
