This is not looking good. I have tried to re-attach the old ( probably failing ) drive to the test machine, and I see this in dmesg: [ 4566.743139] usb 1-5: new high-speed USB device number 27 using ehci_hcd [ 4566.861622] usb 1-5: New USB device found, idVendor=0bc2, idProduct=3320 [ 4566.861625] usb 1-5: New USB device strings: Mfr=2, Product=3, SerialNumber=1 [ 4566.861627] usb 1-5: Product: Expansion Desk [ 4566.861628] usb 1-5: Manufacturer: Seagate [ 4566.861629] usb 1-5: SerialNumber: 2HC015KJ [ 4566.862054] scsi8 : usb-storage 1-5:1.0 [ 4567.865494] scsi 8:0:0:0: Direct-Access Seagate Expansion Desk 0711 PQ: 0 ANSI: 6 [ 4567.866036] sd 8:0:0:0: Attached scsi generic sg4 type 0 [ 4567.869533] sd 8:0:0:0: [sdd] Spinning up disk..............ready [ 4578.911055] sd 8:0:0:0: [sdd] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 4609.862126] usb 1-5: reset high-speed USB device number 27 using ehci_hcd [ 4624.964140] usb 1-5: device descriptor read/64, error -110 [ 4640.167241] usb 1-5: device descriptor read/64, error -110 [ 4640.370138] usb 1-5: reset high-speed USB device number 27 using ehci_hcd [ 4655.472298] usb 1-5: device descriptor read/64, error -110 [ 4665.690010] sd 8:0:0:0: [sdd] Test WP failed, assume Write Enabled [ 4672.640209] sd 8:0:0:0: [sdd] Asking for cache data failed [ 4672.640211] sd 8:0:0:0: [sdd] Assuming drive cache: write through [ 4672.643323] sd 8:0:0:0: [sdd] Spinning up disk.......................................................................................................not responding...

With these errors, would it be worthwhile trying to extract the drive from the case and try it either internally or in another case?
