And 6619 hours of use. Almost a year if it was continuous use.
More like 3/4ths. It's still a lot of defects and I guess the've all appeared rather lately (or dcr should have noticed earlier). So, it actually depends on when the defects appeared. 6k hours is not "infancy"/DOA, but already in the "stablest" phase of "bathtub curve of disc-deaths". And in that case e.g. googles data suggests immanent and permanent death and/or at least more defects and corrupted data "soonish".
...
But I've got discs with >20k hrs (and start_stop_counts >4k) that have no defects (detected by SMART) (I recently switched the older 160G IDE, that had IIRC ~23k hours, for a new 500G in the old box).
Me too.
I think I've used and use >24 discs in the last 5 years (got 4 IDE discs in the old box, 2x500G, 300G, 160G), so I've got a currently running sample of 14 discs of varying ages and sizes, IDE and SATA, with IIRC at least 5 disc replaced (size/death reasons) in the last 2 years.
I had one die with about... no, look, I have the data: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 699 5 Reallocated_Sector_Ct 0x0033 001 001 036 Pre-fail Always FAILING_NOW 30748 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 618 187 Reported_Uncorrect 0x0032 001 001 000 Old_age Always - 1277 195 Hardware_ECC_Recovered 0x001a 061 049 000 Old_age Always - 171943716 197 Current_Pending_Sector 0x0012 012 011 000 Old_age Always - 1806 198 Offline_Uncorrectable 0x0010 012 011 000 Old_age Offline - 1806 Very young, you see. Actually, one year old, 320 GB, used for backup data; that's why the hour count was so low. I used it via USB, so it wasn't till I got a new computer with eSATA ports that I could run smartctl on it... and got a nasty surprise. I didn't lose anything, as far as I could see. And I got a replacement from Seagate, free of charge (except for the packaging cost from me to them), refurbished, which I don't know if I can trust or not.
So, I retract my "DOA" (didn't think of the Power On Hours then, and 72 Start/Stop would be <= 36 days here ;), but 270 defects after a mere ~6.6k hours is way too much for my liking. Less than 10 (appearing soonish), and then stable for at least a month, I'd still not trust the disc, but might use it for a while longer (as I do with above mentioned 1.5TB) for expendable data (caches, tempfiles, whatever one can lose or get corrupted at any time and have no worries).
I think the pending count simply means that there hasn't been a write to those bad sectors, so there wasn't a chance to remap them - or in my case, because they were spent. - -- Cheers, Carlos E.
