ANONIMNIQ Posted April 6, 2019 Share Posted April 6, 2019 Last apps that I installed before getting this error are Paragon NTFS driver and Patallels Desktop. I'm not sure if some other these cause this error. I attached second SATA HDD and at first everything works fine, but after reboot start getting this error and system boot really slow. After half an hour It's on the desktop, I unmount second drive, turn off the system and remove it, but after boot still get this error and boot really slow. I even reinstall Mojave but without formating HDD because I want to keep my settings - It's still the same. I put Apple AHCIPort.kext v328 in L/E but still no luck. How to fix this and make my system boot faster again? Link to comment https://www.insanelymac.com/forum/topic/338208-disk1s1-io-error-on-boot/ Share on other sites More sharing options...
ANONIMNIQ Posted April 6, 2019 Author Share Posted April 6, 2019 (edited) Yes disk1s1 is my macOS partition. S.M.A.R.T status is Verified, complete first aid without problems. What to do next?

ANONIMNIQ Posted April 6, 2019 Author Share Posted April 6, 2019 (edited) HDD. How to check that volume is intact? Btw I check the drive for bad sectors too. For backup as I know I need to store time machine file on other drive but don't have any drive for this now. I tried with other Clover version too and is the same thing, booting really slow with the same I/O error. With Paragon the only thing I do is to unmount partitions for my other drive and remove it after shut down trying to fix this error, nothing else.

ANONIMNIQ Posted April 6, 2019 Author Share Posted April 6, 2019 My important files and my desktop files and data are synced to icloud. I perform fresh installation after formating HDD now.
