read all that in the drive label. There was a time when seagate made
good hard drives. One of my cnc'd machines has a 250G in it, shut off
only for new installs, still running wheezy. No reallocated sectors,
the last time I looked, at probably 90K+ spinning hours its fine. I'd
query it, but smartctl seems to have been removed, so what now serves
that purpose of interrogating a drive on wheezy??
I don't think so, unless you removed it yourself:

Take your pick.

Something seems to have removed it, but it does re-install okay but
I get wildly different, and confusing readings for some things:
Power_On_hours I think has rolled over at 100000, while head
flying hours is a much much larger figure that doesn't make sense:
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail
Always - 0
9 Power_On_Hours 0x0032 060 011 000 Old_age
Always - 35517
12 Power_Cycle_Count 0x0032 100 100 020 Old_age
Always - 239
240 Head_Flying_Hours 0x0000 100 253 000 Old_age
Offline - 114378h+51m+54.298s
This after doing a -t long yesterday. First time in several years. There
is a
900WA ups on that machine for about 4 years now, holds up well while
the 20kw kohler in the back yard is getting spun up, takes 5 or 6 seconds.
Make sense out of that if you can. I'd assume head flying hours would
closely match POH if a 1 was added in front of POH, but that doesn't fit
by quite a lengthy row of apple trees. In any context, that drive is
healthy.
