whoops wrong disk 1677.90GB don't line up with any normal size drive.
My 4Tb is Disk is disk 3 showing 3725.90GB

I did check the sata drivers in device manager, but I will check the version number when I finish work.

Yup. thats the right size for a 4TB drive. Its because manufacturers measure drives in base 10 (makes them seem bigger than they are in marketing), and the computer measures in base 2

4,000,000,000,000 / 1024 = 3906250000 (KB)

3906250000 / 1024 = 3814697.265625 (MB)

3814697.265625 / 1024 = 3725.290298462 (GB)

= ~ 3725.29 GB that you see.

I think whats happening is exactly what the page i linked to says. He's seeing the drive minus 2.2TB

and working it out -

4,000,000,000,000 - 2,200,000,000,000 = 1,800,000,000,000

1,800,000,000,000 / 1024 = 1757812500 (KB)

1757812500 /1024 = 1716613.76953125 (MB)

1716613.76953125 /1024 = 1676.380634308 (GB)

= ~ 1676.38GB which is almost exactly the figure he sees. It's not taking off exactly 2.2TB, but close enough.

Edit - I figured out the discrepancy. It's taking off exactly 2TB (base 2)

2TB x 1024 x 1024 x 1024 x 1024 = 2,199,023,256,000 (Bytes)

4,000,000,000,000 - 2,199,023,256,000 = 1,800,976,744,000

1,800,976,744,000 /1024 /1024 /1024 = 1677.290298045 GB

near as dammit the 1677.30 that windows shows (there's probably some truncation and rounding errors knocking off that 0.01 tongue.gif )

so that's up to date, and is the 10.0.1 recommended on the intel site, so tick that off.

nope! it needs to be version 10.1 or higher. You have 10.0.xxxxx.0. You need a newer version.

also noticed that it's a Microsoft Sata controller, not intel. Probably have to find Microsoft drivers for it.

Can you go into the BIOS, and have a look at what it is detecting it as?

Actually, I just found this, which could be exactly your issue. - http://knowledge.seagate.com/articles/en_US/FAQ/218615en

Also I seen the BIOS has an Intel RST setting in it too, maybe try disabling that, and see of an updated driver in the OS might sort it? (You want to look under Advanced / PCH configuration)
IRST was disabled already in bios. I enabled it but it said no valid ifts partition. Made no change to things though.

frown.gif .... ok... What windows are you on? is it win 10 64-bit?

EDIT : go back to the link, and grab the floppy zip file for whatever bit OS you have.

f6flpy-x86.zip - For 32-bit versions of the operating system
f6flpy-x64.zip - For 64-bit versions of the operating system


Once you have it, unpack the zip into a folder, then go back to the device manager sata controller, and update driver, and manually point it to the folder where you unpacked the ZIP - it should update the SATA/AHCI driver.

it says the best drivers are already installed and did nothing.
