Reallocated sectors

[glennd]

For the exercise, I took a WD5000LPVT (blue 2.5 inch) earmarked for destruction and ran the Deepspar RDT tool on it. It came up with zero bad sectors, while SMART shows 139 reallocated sectors. Is this expected? Does reallocation mean those bad sectors are forever inaccessible/invisible? Does that also mean that, all things being equal and the creeks don't rise and no further bad sectors materialise, the drive is actually ok to use?

I'd use it, on *my* tinker system(s) at home, on a system for non-critical use, on a system that's not used for storage of backups, with a quick glance at gsmartcntrl every week or month to see if things are going further south. (you've already found good use for it, practice with recovery tools!)

Customer's system? Replace, of course

Yes, it's expected. The bad sectors have been relocated to good sector as defined in the g-list. This is normal and all drives will eventually have relocated sectors.

"When the sector is determined to be really BAD then the defect is added to the G-List and the reallocation sector count on S.M.A.R.T. will increase."

The other interesting thing i noted was the total absence of an ahci system in my workshop! RDT took about 24 hours to go over it. Maybe it should be called PRDT.
