TS3410D Not seeing External HDD

[CraigBob]

Hi  all,

I've had a Buffalo NAS for a number of years that I've had an external 12 tb drive attached to it. It's worked flawlessly for all that time. I recently decided to add an additional external HDD this time a 20tb Seagate.

This is external drive is partitioned as EXFAT that is not recognized by the Buffalo NAS. The drive has a small FAT partition that is recognized.

I was under the impression that Buffalo recognized EXFAT. Why isn't this one be recognised?

The NAS will only recognize the first partition of an externally connected HDD, this this case the small FAT partition. Either try to remove this partition using diskpart or use a USB HDD that only has a single partition.
