I am attempting to troubleshoot a hard drive that appears to have gone bad. I removed the drive and using Acronis to access the drive via an external usb connection. The drive appears in windows with a drive letter but no drive letter in Acronis and the status is Healthy and active. In Acronis the file system is reported as Not Formatted. It takes a long time for this to finally appear in Acronis or windows explorer. Recovery Expert does not appear to detect any problems. Is there a better program to use to attempt to recover the disk?
