I back up my network monthly to a 3 to 4TB HD, and store the drive. I have been using usb 2.0/3.0 SATA adapters for this for almost ten years. I probably have a dozen or more of these adapters, some originally bought back when I was only using 1-2 TB drives.
Recently, it seems that many of these devices cannot read/access these bigger drives: I format the drive to max (3-4 TB), write the data, verify that the data can be read, and store the drive.
However, putting a drive in a different device, it won't read the data, or even recognize the drive. In Disk Management, it appears only to recognize an "2048GB Healthy (GPT Protective Partition)", and a "1678GB Unallocated" one. In other words, it seems to be unable to recognize the actual GPT format of the drive. Some of the drives will never recognize the GPT; some do occasionally; some will if attached to a USB 2 port, but not a USB 3. Many work part of the time.
Usually, I can remount the drive in the original toaster and read the data, but there have been a few instances where I could not even get that to work. So far, I have always been able to find a device that eventually would read the data, but this is a troubling trend.
I can't seem to find any discussion of this.
Servers: MS Server 2012R2 (same problem with 2008R2); Windows 7 & 10. USB adapters from Rosewill, Masscool, IcyDock, StarTech, Orico, Thermaltake, etc.
