Need advice analyzing S.M.A.R.T data of HDD in "Imminent disk failure".

[Luis Maceira]

In Ubuntu9.10 I have received warnings that a HDD is in pre-failure.

The disk(Iomega Prestige mobile USB external) has 1 month.

In Debian Testing and OpenSolaris(installed on the same HDD I

have no warnings.).Using smartmontools (this disk is not in its

database) I get below:

me@mycomputer:~$ sudo smartctl -T verypermissive -a -d sat --health /dev/sdb

This is a Ubuntu issue, really, Ubuntu has implemented new stuff , device-kit (ata)
among others. This has resulted in Smart error messages in user space, where it
has caused many  (users) to wonder wtf.

It is still the same info, Smart enabled drives, you probably didn't test with  
smartctl very often, at least I didn't.

AFAIKT, if  ' Reallocated_Sector_C, & ' Offline_Uncorrectable' equal zero the drive
firmware is still doing its job of remapping bad blocks.

 Lots of info on google, dating way back, on smartmon tools.

This is the complaint.  Perhaps the disk won't spin up some day, making
the data inaccessible, or perhaps the disk just didn't get enough power
one time (use an external power supply to prevent a recurrence).

I don't think there is any way to get Palimpsest to not complain other
than to shut it off.

In the past I have rendered a drive amnesiac by updating its firmware,
but I can't really recommend that, and it's a hassle.
