Maxtor was long ago acquired by Seagate, but you can still come by their NAS. This is one of the older cases:
I have a 1TB Maxtor drive attached to my network. It has recently failed and I can no longer access it. However, it is still shown on the network list in Windows Explorer, …. I can ping the drive and get a return. … important that I can get my files back. Does anyone have any ideas on some software that might be able to access it?
Sure, I have. Home NAS Recovery works with Maxtors too. In the end, it is the equivalent of the modern Seagate NAS, albeit with only one disk.
It may be interesting to note that the poster refers to the NAS as 1TB drive. This may cause some confusion with a regular external drive, but the external drive is attached to the PC, not to the network, and you cannot ping the external drive.
