I recently installed win 8 on new clean 1Tb hdd but forgot to firstly disconnect the second 250Gb hdd disk #0, so the OS ended up on disk #1. I then disconnected the 250Gb drive and reinstalled Win 8 on the 1Tb drive. I then checked Disk Management and found, as I thought, that the 1Tb drive was now disk #0.
However, when I reconnected the 250Gb drive and then checked Disk Management again I found that the 1Tb drive had reverted to disk #1 and the 250Gb to disk #0. I would prefer that my 1Tb C:\ drive be disk #0. Could I achieve this by swapping the SATA connections on the HDDs or on the motherboard?
Help appreciated.
Pedro

Hello Pedro,

Yes, that would be correct. Whatever the SATA port number the disk is connected to will be the disk #. :)

Hi Brink,
Rather puzzled. I changed the SATA leads over at the HDD end (shouldn't matter which end should it?) and when I booted it up, nothing had changed. My 1Tb C:\ drive was still disk#1 and the 250 Gb D:\ drive was disk#0.
Everything works and boots up ok so I think I'll leave as is. Presumably there are no ramifications as to whether the C:\ disk #0 or #!
Regards,
Pedro.
