1304215 2012-09-30 23:52:00 Ubuntu's disk utility is not inaccurate when it comes to reading SMART data, if the drive has failed sectors they will show up in there. Agent_24 (57)
1304216 2012-09-30 23:54:00 wanna bet ?

Had a drive here last week , over 5000 failed sectors and Ubuntu wouldn't even see the drive ;)

But the data recovery software did.

What do you mean by "See" ? That it couldn't read the partition? Or the drive did not show up in Disk Utility even under the appropriate storage adapter?

1304218 2012-10-01 00:13:00 By "see" I mean the drive, when booting from a Ubuntu CD it couldn't detect it, the only drive it saw was the healthy original System Drive, not the slaved one. wainuitech (129)
1304219 2012-10-01 00:42:00 Thanks,
Yes it's odd that most of disk is reported as free space. It makes me suspicious. I haven't been able to contact the owner as yet. It'd be great if they told the whole story at the start!

The other issue with cold booting needing a few attempts. I re-ran it from cold just now.
The first attempt, the I got no monitor... I rebooted.
2nd attempt, I got monitor and it progressed to boot off the CD with Ubuntu, then it quit with black monitor....I rebooted.
The 3rd attempt, it booted off the CD as it should have the 1st time.

Ubuntu does report smart as healthy
.
Thanks

1304220 2012-10-01 11:36:00 I'm not trying to hijack this thread but thought this might be helpful :2cents:

I'm just having a look at my niece's PC now which seems to have a faulty hard drive.

I'm using the PartedMagic live Linux CD and running the Disk Health program (GSmartControl) which says the drive's Overall Health Self-Assessment Test PASSED. But running the short self-test shows read failures and it reports some sectors are bad. This is at the bottom of the "Current Pending Sector Count" and "Offline Uncorrectable" sections-- Quote: "Notice: The drive has a non-zero Raw value, but there is no SMART warning yet. This could be an indication of future failures and/or potential data loss in bad sectors."

So it seems that although the SMART data says the drive is still OK the fact is the drive is failing. I'll run the more comprehensive extended tests tomorrow. The drive definitely seems to be flaky and wouldn't load Windows at all just now but started OK earlier on today.

1304221 2012-10-01 21:14:00 Its not Hijacking Rod, but it does confirm what I mentioned before that Linux doesn't always read accurate relating to drive status relating to sector health. wainuitech (129)
1304222 2012-10-02 00:58:00 That behaviour is not exactly unique to Linux.

As I am sure you are aware, all drives with SMART have trip-points for the attributes. A drive may have to gain for example 200 bad sectors before SMART itself warns that the drive is failing (Then you may get an error from your BIOS at POST) Even if it has 199 bad sectors SMART will give it a clean bill of health as it has not reached the threshold of 200.

Disk Utility in Linux does seem to base its overall evaluation of the drive's state on what SMART thinks of it, however since I do not have a habit of using failing drives I am not exactly sure what Disk Utility would say about a drive that obviously had problems but had not yet tripped a SMART warning itself.

I do know that it will report any reallocated sectors, and it also displays a readout of all the SMART attributes and raw values so you can peruse the data and come to your own conclusions yourself.


But in any case, I prefer to read SMART data with either SpeedFan in Windows or HDAT2 from bootable media. Both programs ignore SMART's conclusion of the drive health and give you a more sensible idea of what's actually going on.

1304223 2012-10-02 02:03:00 It was mentioned in Post #4,HDD Regenerator , that will tell you how many and what sectors are bad. You can tell it to start at a certain Sector, or from 0 - (insert number or allow default/complete drive).

I use the program mainly for testing failed sectors. Last one I did took a while to run, 3 days, and over 5000 failed. While I wouldn't trust the drive, it did allow some data to be recovered.

1304224 2012-10-22 11:24:00 Update:
The owner said there was no valuable info on it so:
I run the recovery software and reinstalled windows.
Then I run Speccy and found the CPU and motherboard were overheating. Something like 85c.
I've cleared the fan and heatsink of lint and dust.
The laptop is still temperamental at starting. In fact I haven't been able to get it to boot plus the monitor is not working.
It strangely 'power cycles' on - off -on - off a few times, then the fan remains spinning but no boot or monitor.
Google gets some hits on the strange on -off power cycle phenomena but I haven't found a solution as yet.
Could the overheating be the root cause of this issue?? Damage to CPU, mainboard etc?

The power supply is a Toshiba part, rated at 19v and also tested at 19v.
I forgot to look at the power jack connections when I had the laptop apart. Maybe I will look at that tomorrow.
