I recently had a hard disk failure so re-installed Vista on what was my secondary drive.
I then purchased a Hitachi 500g SATA drive. Unfortunately Vista will not recognise the drive. It doesn't show up in Disk Management. At times it will show in BIOS but not always, and even then it doesn't show in Vista.
Windows 7 users: Start-->right click Computer-->Manage-->Storage-->Disk Management. My second hard drive (both 1TB Western Digitals) was listed as offline. Right click the disc number (mine was Disc 3) and select online. You should be good to go - it worked for me!
it seems that your hard drive is in a different formats if you goto start - right click my computer and click properties - then click device manager , goto disk drives and see if you see your harddrive that you installed if so that means vista know its plug in but the problem is in a different format besides , exfat , fat , fat 32, or NTFS
my solution is find a program that will detect the hard drive and format it
or use Linux or mac to format to the types of format that windows can read
as explaned in no:3 everything works great,and if you have a new empty that your computer will not recignise ,right click open volume to let your computersee how much space it has and folow the wizard.hope this helps.GOOD LUCK AND BE PATIENT.
Thank you! It has taken me ages to figure this out. I had a SATA hard disk with data on it. Ran it externally with a Vantec NexStar CX and it was not being recognised. The disk manager showed it as "Disk 1" Dynamic with the exclamation mark. The right click and import drive did the trick. AaaH! So easy. :)
