Ok, I know that the raw data reported by SMART is essentially proprietary, and so we should really only pay attention to the "Current", "Worst" and "Threshold" fields. However I've never come across a HDD that didn't report the actual number of reallocated sectors in the SMART raw data.
I just bought a "Toshiba Canvio Simple 3.0", which is a 1TB external USB powered usb3 drive, and I was a bit alarmed to see the raw data for reallocated sectors count was "...00F0" straight out of the box!
I returned the drive to the shop and they gave me a replacement, which initially reported zero reallocated sectors on the first usage. However after I got home and ran a "chkdsk /r" that blew out to "...001658" in the raw data, and the "Crystal Disk Info" software I'm using reports an "Amber Warning" on the drive.
The thing is, the "current" and "worst" fields still read 100 (with threshold = 50), so I know that the drive must actually be healthy. Also chkdsk /r found no bad sectors. So I tend to think that the drive is actually ok and that this is just something weird about how Toshiba handles the raw data for realloc sector count.
Anyway, just wondering if anyone else has noticed this anomaly with the SMART data from Toshiba drives lately. BTW, Crystal Disk Info reports the drive as being a "TOSHIBA MQ01ABD100" if that means anything.
