I have 3 hitachi drives that came out of a IBM storage array, they are being re-purposed for another project. Only problem is when I hook them up to my windows 7 machine via sata connectors they are only displaying 372gb of usable space, these drives are 750gb. In disk management the drives only display the 372gb volume. How can I reset the partition size on these drives?
You can delete the partitions in Disk management then format to NTFS and create primary partitions.
Likely the array was two of these 372gb HD's which totalled a 750gb RAID. So each HD should be showing its own size now if you have not reconfigured an array.
What is the SATA controller setting in BIOS setup?
well, the capacity listed on each drive is 750gb so I do not believe that is the issue, not sure on the bios, I'll need to check on that.
update: The bios reports the drive is 400gb in size
the SATA controller setting the BIOS is IDE
Part No. HUA721075KLA330
Google search of this part number clearly shows it to be a 750gb drive so I'm not sure whats up
Hitachi has good bootable drive diagnostics, so I'd burn it to CD using Windows Image Burner to run a full scan on the problem HD's: Hitachi Drive Fitness Test
Then I'd wipe the HD, create a full disk partition marked Active using Step 2.2 in SSD - HDD Optimize for Windows Reinstallation in order to run Disk Check from the booted installer or Repair CD Command Line, or from the OS by installing in another PC.
