I recently purchased a refurbished WD Passport external hard drive. It arrived today and I plugged it in. I was able to access SMART through USB which I was really hoping for! I checked the readings with Hard Drive Sentinal. Right off the bat I noticed Reallocated Sectors Count says 140. Is that OK? Some other values have since changed in the table because I started copying over some music files, but Reallocated Sectors Count was the only one that originally stuck out. I'm just interested in knowing if there's any wear and tear already on the drive considering it's refurbished. Thanks.

These are the current values as I'm currently copying over the music.

I have a paid version of Hard Disk Sentinel.

Aside from the temperature data...about the only thing that matters is the status of any drive or check.

Worrying about drive sectors...ia nor going to be fruitful. Drive sectors are reallocated when the utility (example, chkdsk /r) finds that data files lie in/on damaged sectors. The data is just moved to a new location on the drive.

As long as OK is in the status column...nothing to worry about.

Thanks for the info, hamluis. Won't there be a point when the area sectioned off for reallocated sectors fill up though?

Hard drive sectors...are very small, with more than you can count on any hard drive. One or more of the following may assist you in trying to grasp just how meaningless a sector might be on a hard drive. Every hard drive has unused sectors...which are then used when data is found and removed from bad sectors.

Hard Disk Sector Structures - http://www.dewassoc.com/kbase/hard_drives/hard_disk_sector_structures.htm , the first two paragraphs should be enough.
