Thanks for the various replies.
In no particular order :
This is (currently) the only external disc drive I've got, so swapping it for another one isn't possible (but it looks as though some shopping is in order :-( ).
No I haven't tried the disc on another machine, I probably won't have time before Thursday PM at the earliest.
The disc runs off its own power supply, rather than using the USB lead, so I'm not sure what I would gain by running it via a powered hub.
Since putting up the original posting, I've managed to get smartctl working :

SMART Error Log Version: 1 ATA Error Count: 12 (device log contains only the most recent five errors) CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status register [HEX] Powered_Up_Time is measured from power on, and printed as DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes, SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 12 occurred at disk power-on lifetime: 35414 hours (1475 days + 14 hours) When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were: ER ST SC SN CL CH DH -- -- -- -- -- -- -- 40 51 00 ff ff ff 0f Error: UNC at LBA = 0x0fffffff = 268435455
Commands leading to the command that caused the error were: CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name -- -- -- -- -- -- -- -- ---------------- -------------------- 25 da 08 ff ff ff 4f 00 20:04:50.024 READ DMA EXT 25 da 08 ff ff ff 4f 00 20:04:46.778 READ DMA EXT 25 da 08 ff ff ff 4f 00 20:04:21.724 READ DMA EXT 25 da 60 ff ff ff 4f 00 20:04:21.721 READ DMA EXT 25 da 08 ff ff ff 4f 00 20:04:21.609 READ DMA EXT
I'm not sure I'm convinced by the line : "SMART overall-health self-assessment test result: PASSED"
