I purchased a Sabrent external drive reader -- it accepts SATA and SSD drives. Essentially, it turns them into stable flash drives. I use my stack of HD for backing up large data sets, such of photos. I also have a stack of small EIDE drives that I can't read. My current MB doesn't have an EIDE connector and the external caddy doesn't have the interface. I'm afraid to recycle them as I have no idea what's on them. Could be old files backups, including financial records.
