Look very carefully for a jumper on the back of the drive that sets its limit to 32 gb. It's not likely this is your problem but you should rule it out. This was to accommodate some older BIOS that couldn't handle larger drives but the jumper was incorporated into many newer drives as well.
From previous discussion, my 1TB internal hdd wouldn't boot up. Reseller supplied an identical hdd with 7 and all pre-installed software; that seems to be working. I did a 7 restore but that doesn't restore programs, which i'd like to recover from the original hdd. setting up original as an external hdd, it wasn't recognized, "no system recognized; disc must be formatted." It did show as 32GB (down from 1TB.) thinking the case might be limited, got a new case for up to 1.5 TB discs. Still only shows 32GB. Quick Format NTSF done; shows as active healthy MBR partition.
1.) How can i use all 1 TB?
2.) Any way to recover my data? most of the drive has not been reformatted, if it's truly 32 GB. tried Recuva, also another one; doesn't find anything.
3.) If i can format 1TB, how can i tell if i can mount as secondary internal hdd?
I have not changed any bios/cmos setting; didn't touch any jumper clips, removing from internal and placing into external case. it's a WDC disc.
