After a crash and a reboot I noticed I'm suddenly unable to mount one of my hard drives and got this error message instead block count 488378134 exceeds size of device (488377869 blocks)
. I got two hard drives of this model so I compared the sector count of the affected one with the one working normally by running fdisk -l
.
The one that can't be mounted anymore reads 2000397852160 bytes, 3907027055 sectors
while the normal one reads 2000398934016 bytes, 3907029168 sectors
. It seems that I lost 2113 sectors. Does this mean these sectors have gone bad? Why weren't they replaced?
What perplexes me is that the affected hard drive only is about a year old, wasn't mounted during the crash and has perfect SMART values (0 Offline_Uncorrectable, 0 Reallocated_Sector_Ct, 0 Current_Pending_Sector, etc).
hdparm -N /dev/sda
report?max sectors = 3907027055/3907029168, HPA is enabled
.HPA is enabled
is the clue. Investigate it. Another question is: why is it enabled?
