most of the attributes are ok.
The failing ones are of type *old age*, so the manufacturer thinks
the disk should be replaced, when it reached this age.

The report shows no sign of it.

But you had a problem - perhaps with cabling - in the past, which is resol=

To check for bad blocks you should run an extended selftest.

Manufacturer said the disk has reached it's lifetime.

This value increases quickly, if you have suspend mode active.

Still beyond the thresh, but not far away from it.

Depends on the importance of the stored data.=20
It it's ok for you, to restore from last backup, when the worst case happe=
ns,
you can use it further on.
But you should execute short and extended test on a regular basis.

Re: [smartmontools-support] Condition of my hard drive: PASSED but with problems ???

Hi,

failing_now status usually means you have at most one more successful power on 
or a couple of hours of usability of your drive...and feel lucky if you can 
backup your data. In a real SMART error situation your drive is dying.

But in your case,
Having garbage at the end of lines, it seems to me that smartmontools 
misinterprets data structure. If you use IDE or SATA drives with recent 
kernel did you use "-d ata" flag?

Try:
smartctl -a -d ata /dev/sda

Run offline tests:
smartctl -t short (-d ata) /dev/sda
or 
smartctl -t long (-d ata) /dev/sda

After 1-3 minutes for short test you would see in smartctl -a status page 
something like this:

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  
LBA_of_first_error
# 1  Short offline       Completed without error       00%     13729         -

If offline test reports sector error, there IS an unreadable part on your 
disk. Try to read scan whole disk by "dd if=/dev/sda of=/dev/null bs=512".

I suggest you also add 'iflag=direct' to bypass the Linux block buffer 
layer.

failure of *pre-failure* attributes indicate critical errors.
But in this case the failures concern only *Old=5Fage* attributes.

Where did you see *garbage at the end of lines* in his report=3F
