Thinkpad T410 with SATA 2.5 drive. Upgraded drive to an SSD, got external 2.5 Sata enclosure to reuse old drive as a data drive. Cannot get any windows7 machine to recognize it. Show as not initialized and cannot initialize it because it gives me a Data Error (Cyclic Redundancy Check) error. I verified that the drive was good by putting it back into the laptop and throwing a win7 fresh build on it. All I want to do is take former laptop drives( that were boot drives) and re-format them and put them into external enclosures to use as external data drives. Many thanks for any help. I have tried several drive utilities, even booted Ubuntu which allowed me to format the drive and start clean ..with no luck.
