when trying to copy a certain file, i get the message: cp: reading 'file' : Input/output error
It is likely that the disk has one or more bad blocks. Use `smartctl -a /dev/sdx` to see all the data (or -A to see only the attributes) and look at the raw values of Current_Pending_Sector and Reallocated_Event_Count. The first reflects unfixed problems, and the second fixed problems. If both numbers are low,
13 & 0
I would just keep
using the drive, though I would first do a long test with `smartctl -t long /dev/sdx` (wait until the indicated time and then do a `smartctl - a /dev/sdx` to see what happened)
should have more data from this in 4 hours.
and then enabled Automatic Offline
Testing with `smartctl -o on /dev/sdx` (this will help keep up with sectors as they go bad, without unnecessary data loss).
A program such as ddrescue (`yum install ddrescue`, `info ddrescue`) may help to salvage the damaged file(s).

the file itself is not important, but i don't want the error to migrate to one that is..
