I've got a WD160AVBB hard drive that I'd like to put in my TF5810. As a precaution I checked the hdd first using Western Digital Data Lifeguard Diagnostics. It failed the tests, reporting bad sectors, specifically that there were "write zero errors" for sectors 312,581,632 - 312,581,809 (the disk size reported as 312,581,808 sectors).

It strikes me as odd that the problem is with the final 177 sectors. Is there a plausible reason to doubt test result?

Even if there are some bad sectors, could the disk still be reliable? Does anything critical go at the end of the disk, does the Topfield need those particular sectors?

Bad sectors are usually a sign that the disk is starting to fail, I suspect that it will get progressively worse.

Try using it in the Toppy but monitor it using the HDDInfo TAP regularly to see if more sectors are failing.

Currently the SMART readings for reallocated, pending and uncorrectable are all zero.

I'd have thought that a write error would have triggered the firmware to reallocate the sector and that would be recorded in the SMART data. I'm puzzled why the write zero errors aren't apparent in the SMART readings.

If you really want to keep using this drive, download spinrite from grc.com. It does a very low-level fix on a disk. It's rescued a couple of disks with corruption for me. Costs to buy, though...
