I recently installed arch install on my USB-HDD, a Toshiba Store E steel 2.5" 320 GB.
Everything is fine, but I'm getting this annoying error when I boot:
ata_id: HDIO_GET_IDENTITY failed for '/dev/sdb'
What is this error about ?
Different scenario: Supposing the USB-HDD is connected to my laptop during the laptops boot up, the same message shows.
Does anyone know why this error keeps showing up?
Hello. I've just seen your post after Googling for the same error myself. (I boot and run from a usb hard disk.)
I found this helpful:
Drive errors in the system log files
/dev/sda: HDIO_GET_IDENTITY failed: Invalid argument
This error is produced by hdparm when using the -i switch on some SCSI and SATA disk drives. hdparm was not designed to be used with SCSI or SATA drives. No tweaks that hdparm can provide are needed for SCSI or SATA drives.
Fix: Disable any Cpanel IDE hard drive tweaks and remove any hdparm settings in local startup files.
When I performed
hdparm -i /dev/sdb
I did indeed get that error. I don't know which startup file/config is running that command, but it doesn't seem to be problematical and I'm ignoring the error message until I can be bothered to track it down!
