I've been backing up old IDE hard drives onto a new USB drive this afternoon.

One, a 2002 120gb Western Digital, has been a bit of a problem. I have connected it (as with the other hard drives) to the IDE port on the motherboard, and when I power on the computer, it makes clunky/whirry sounds which I'd prefer not to hear. Clunk, whirr, HDD powers down, powers up, OS tries again, then eventually the OS (OpenSuse right now) loads.

The relevant output from dmesg is as follows:

[    1.044144] ata1: clearing spurious IRQ
[    1.065767] ata1.00: ATA-5: WDC WD1200JB-00CRA1, 17.07W17, max UDMA/100

[    1.081722]  sda:

In fdisk -l, nothing relating to sda shows up. What I was hoping to do, was do a big ol' dd copy of /dev/sda, then use photorec or something to get some files out of it. The fact that it was recognized in dmesg is encouraging, but I'm wondering whether there is in fact anything to be done.

Would be grateful for any help in deciphering the dmesg info!

  • What does fdisk -l -u s /dev/sda say (-u s stands for using sectors as size units)? – peterph Jun 1 '14 at 12:58
  • Hi peterph, there's no output from that command - I presume because the OS isn't detecting a partition and therefore isn't allocating a /dev/sda. – Nathan Jun 1 '14 at 22:49

Any noises other than the normal hum from a HDD is bad news. This typically the result of either bearings that have or are disintegrating over time, or from the head as it's banging into the guards on either side as it searches in vain for specific sectors. If it's, by some miracle still operating, I would attempt to get any data off the HDD that's critical and stop using it immediately.

The last message is telling you that the HDD is being detected by the sd driver but there are no partitions to be had.

[    1.081628] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[    1.081722]  sda:

Specifically that last line. You'd normally see this if there were partitions:

[336660.757985]  sdb: sdb1

So what ever partitions were there would seem to be lost. I'd not waste my time in further attempting rescue unless there's absolutely critical data on this HDD.

Tools

I've used these tools successfully in the past to breathe life into dead/dying HDDs but it's a crap shoot. Many of the tools/techniques are discussed in some of these Q&As. Also search this site for others.

  • Thanks slm. I'm not sure what's on this hard drive, so I can't imagine it's too important. I've decided to abort the whole exercise and instead enjoy some new strong fridge magnets. Thanks for your help. – Nathan Jun 1 '14 at 22:51
  • @Nathan - ha. We just had 2 HDDs die at work and I elected to do the same thing with the magnets 8-). If you want can you mark this as the accepted A so everyone knows your issues been resolved? Thanks. – slm Jun 2 '14 at 0:05
