Windows 7 Professional 750GB Hard drive, no corruption, chkdsk shows now errors.
I installed a new internal 1TB hard drive in the laptop. Plugged in the 750GB drive via USB enclusure.
I copy over files (a folder of jpgs for instance).
If I view them on the USB enclosure, or if I view the copied files, they are corrupted. Chkdsk on the good usb drive shows tons of corruption. But if I put the 750GB drive back in and bot, everything looks OK.
What could the problem possibly be? At a total loss here.
