I'm running Windows 10 Pro from SSD and before I installed my storage drive (drive H) it would boot up in less than 15 seconds. With my 2TB Seagate drive installed, it has taken as long as 45 minutes to boot! Every time I start the PC, it says scanning and repairing Drive H. I have scanned the drive with SeaTools and it came up with no problems. I also scanned it from within Windows using sfc /scannow and it also found no issues. Even transferring files to the H drive, is impossible as it just stops transferring altogether and causes the PC to freeze and trying to download Steam games to it, results in a timeout error.
It is not listed in the BIOS as a boot drive so I am absolutely stumped! I have replaced SATA cables and changed the SATA port with no difference.
Remove the drive and the PC boots and behaves like it should.
I have replaced the drive twice under warranty thinking that it was a drive issue, but every drive has the same problem. My other 2 HDD's (both 500Gig) have no issue like this at all.
BTW, I have my games folder on the drive, nothing else and it still has about 70% of it's capacity free. It is fine when the drive is empty, but the more data that you put on it, the more it slows the computer down until it gets to the stage where I am at the moment and nothing more can be installed or transferred onto it even though there is tons of storage space available on it.
