I had installed Windows 7 32 bit version, then I install my new WD4003FZEX-00Z4SA0 without any problem.
3 Partitions of 1TB+ 1TB + 1.7 TB
I fill of data the tree of them.
Then I decided to install an SSD + Windows 7 x64 and changed SATA mode from IDE to AHCI in BIOS
Then de BIOS read the 4TB disk as a 1801.8 GBWDC, when windows start, ask for a check disk for the third partition, because it remain out of the 2TB size that bios recognize.
I really star a hard search but nothing goes well… including coming back to old HDD with Windows 7 x86 and SATA mode to IDE.
The Bios continued to assume the HDD of 2TB instead of 4TB !!!
Is there any solution ?
I install the HDD in another PC and it works fine.
