Windows 7 Running chkdsk when I dual boot Win7/Win8

[JimInWoodstock]

I am dual booting win8 and win7. I actually have win8 installed on its own hard drive and win 7 installed in its own hard drive. The win7 hard drive has been in use for the past 2 years and I have had Win8 running for about a week now. I purchased another hard drive for Win8 and left the old Win7 as it was.
I also have 3 other hard drives in the system. Everything is formatted NTFS.
So my system is as follows
Drive C - Boot Drive - I physically swap out the dedicated hard drive for Win 8 or Win 7
Drive D - internal 250 GB sata drive
Drive F - internal 250 GB sata drive
Drive H - internal 250 GB hard drive.
I have been running this config for about 2 years under Win7 with no problems.
The problem that I have now is when I swap the boot drive and boot up a different OS than last time (Like booting Win8, powering down system, swap boot drive, boot Win7) the system always says that there are problems on the all 3 non-boot drives. It runs chkdsk(it least that is what it look like) and processes the 3 non boot disks one at a time which take about 10-15 minutes for all 3. Most of the time it finds no problems, but about 1 out of 5 boots will find a problem with one of the disks and then fixes it. The disks seem to be OK while I am running. I then power down and swap boot drive and reboot the other os and we start all over again. I am powering the system completely down for each system to make sure that the disk cache is flushed.So far the disk problems have been fixed by chkdsk at boot, but I am sure the day will come when the disk cannot be fixed and I will loose data.

Windows 8 has something called fast startup. You might try unchecking it to see if it helps. Control Panel-Power Options-System settings, bottom of page under Shutdown settings.

You should be able to select a boot device with a boot device menu during boot. Physically disconnecting the drives should not be necessary.
