Use a different SATA port, sata power connector and replace the sata data cable of it. check the hard drive for errors with its manufacturers tool
Which motherboard are you using?
This drive was not the boot drive... and yeah all four hard drives are installed correctly and i cant update the firmware as some of the setups that i downloaded were not compatible with Windows 10.. and now i had to disable the drive from the BIOS as i cant turn on my PC if the drive is enabled..Which errors did come up?
Check the hard drive for errors with its manufacturer´s tool
Was this a boot drive?
Are 4 hard drives installed currently?
Eventually update the firmware of the hard drive (backup data before)

well the hard drive is not being detected at all.. so i cant check it in Disk Management.. and now i had to disable the hard drive from BIOS because i had problems starting my PC1st. You may check the drive in Disk Management to see if it has wrong file system. If yes, delete the drive and create new partitions with NTFS or older FAT32 file system to make Windows recognize it.
2nd. Check if there's something wrong with the hard drive. To fix the logical errors, you can use Command Prompt with command chkdsk h: /f (h is the checked hard drive). Or turn to some professional disk manager tool.
