I had an eSATA=20 connection to the host box. It went belly-up a few weeks ago. After some careful searching, a good replacement seemed to be the Oyen=20 Digital Mobius 3R5-EB3-M. Found it for about $300USD. It was plug-and-play replace. Drives were being addressed by UUID in=20 Fedora so no issues at all. It came right up. However, smart reporting looks horrible even compared to the TR5UT+B=20 (which had its own issues). Here's what the TR5UT+B (old cabinet) reported for one disk in the=20 unit (just the header section of smartctl -a): =3D=3D=3D START OF INFORMATION SECTION =3D=3D=3D Model Family:=C2=A0=C2=A0=C2=A0=C2=A0 Western Digital Red Device Model:=C2=A0=C2=A0=C2=A0=C2=A0 WDC WD20EFRX-68EUZN0 Serial Number:=C2=A0=C2=A0=C2=A0 WD-WCC4M6HX8XCR Firmware Version: 0957 User Capacity:=C2=A0=C2=A0=C2=A0 2,000,398,934,016 bytes [2.00 TB] Sector Size:=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 512 bytes logical/physical Device is:=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 In smartctl database= [for details use: -P show] Here's what the Mobius reports now for the same disk: =3D=3D=3D START OF INFORMATION SECTION =3D=3D=3D Device Model:=C2=A0=C2=A0=C2=A0=C2=A0 Mobius=C2=A0 DISK1 Serial Number:=C2=A0=C2=A0=C2=A0 WD-WCC4M6HX8XCR Firmware Version: 0962 User Capacity:=C2=A0=C2=A0=C2=A0 2,000,398,934,016 bytes [2.00 TB] Sector Size:=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 512 bytes logical/physical Device is:=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 Not in smartctl data= base [for details use: -P showall] The disk model is gone. The firmware version is wrong (cabinet instead=20 of disk?!). I imagine firmware updates are impossible here. The rest of it is unimpressive, too. No SCT (TLER) at all - not just=20 ERC, but SCT Status, SCT Feature Control, SCT Data Table are all=20 missing too. All the disks in the cabinet are WD20EFRX-68EUZN0. So I believe they=20 have SCT/TLER. What RAID cabinets would be a better alternative? I have 5 drives but=20 an 8-bay cabinet would work too. Obviously, SMART pass-through would be 'nice'. But so would SCT (ERC). --=20 Kind Regards, Bill Hudacek IT Architect Currently Un-Attached, free & independent
