how you know when your harddrive is going to die

I'm not entirely sure, but maybe from this message from dmesg.

hdc: dma_timer_expiry: dma status == 0x21
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x01 { AddrMarkNotFound }, LBAsect=0, sector=0
ide: failed opcode was: unknown
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x01 { AddrMarkNotFound }, LBAsect=63, sector=63
hdc: dma_timer_expiry: dma status == 0x21
hdc: dma_timer_expiry: dma status == 0x21
hdc: DMA timeout error
hdc: dma timeout error: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: DMA disabled


My colllegue was shocked when I mentioned I buy an average of 2-3 hard drives a year for personal consumption. So I told him that I have more than 3 machines at home with different age groups, it is natural that these drives die and need to be replaced.

The most awful thing about this is that you loose your data which I have several times in the past. I'm sure faithful readers of this blog will have already read the first few articles about data management and have 2 copies of the same data distributed in their homes to avoid such a tragedy.

The drive I mentioned above used to be an external firewire IDE enclosure. I used it on windows and mac. Last I attempted to use it for was a backup of all my Mac data in Mac native's filesystem. To shorten the story, it wiped out whatever was in it. So I decided to do what I normally do with all "faulty" disks. Stick it into a linux machine. They will tell you exactly whats wrong with it.

Now, why can't Windows or Mac OS (didn't check console though) tell you that, it just tells you all kinds of funny stuff and makes your disk un-usable. At least that message was more straight forward and less misleading.

Backups are for losers!

Tell that to the guy who just lost his mp3s after spending 2 weeks painfully converting his CD collection.

in which case, it could be youre damned if you do and damned if you dont.

I allocated my faulty harddrive as another backup drive temporarily. How intelligent is that?
