I use MAC for work and create data which I archive off my MAC once a project is finished, and need to archive/access that data from time to time.
About 1 and a half years ago I purchased a QNAP 219P+. I installed 2 x 2TB drives. I use it for archiving files I want to keep and review/access indefinitely. My intention and the professional advice I was given was by setting up in a RAID 1 or mirrored setup, I would then have a safety measure in place to protect me from dive failure.
I used the drives without major incident (the occasional connection dropout while transferring etc which I have read about on here) till now.
Now that the 2 TB of mirrored data has filled the drives, I purchased 2 new drives, with the intention of filling them up with new data. I then intended on keeping the old drives in a safe place in anti static bags, and using a Hard Drive Docking Station (Newer Tech Voyager Q) to read the old drives if need be.
Yesterday I pulled out the old drives, and during the installation of the new drives took the opportunity to update the firmware for the QNAP NAS. I downloaded off this site, using the March update, and initialized and installed the new drives, and have tested them and they work fine.
However, the old drives would not read using the Hard Drive Docking Station. I was advised this was because the QNAP software is not compatible with my MAC directly, that is must go through the QNAP.
I then removed the NEW drives (both) and installed both the OLD drives to access data and now can't access the old drives. I get the message in Finder "Connection Failed"
If anyone has any tips I'd appreciate it
