Hard disk check
« on: Friday, May 21, 2010, 09:24:04 AM »
Can someone recommend software that check a hard drive for errors etc... or is there nothing surer than doing a slow format of the entire hd?

I'm sure Ghandi can help you with that.






Oh shit, I totally misread the topic.

I tried to come up with a worthy response to that but it was just too good. Well played, sir.

Chkdsk /r

In my experience that seems to miss errors at times.

Harddisk sentinel was telling me I had a single bad sector, but chkdsk told me everything was peachy.

As for Idol, I was trying to come up with a worthy response, but I don't think there is anything called a soft disk.

Well a chkdsk /r does the same check a high-level format does for bad sectors and marks them as bad just a format does.  That's why I mentioned it.

Well I did a regular slow format and it didn't report any bad sectors. Is there any such thing as a temporary bad sector?

No, but if a drive is failing slowly, it will get an increasing number of bad sectors.  It could be fine when you format it, then days later, you'll have new problems.  The best thing to do at that point is image the drive to new one and swap it out.

Hard disk sentinel told me that I had 1 bad sector, the hard disk health was at 99%, and the prediction it had for the HD running at optimal condition was 1000+ days... which is more than enough really.

The problem was that I was downloading some nature videos (no this isn't a euphemism for pr0n, I was *actually* downloading NatGeo documentaries on lions *edit: was proof reading, and read lions as loins...  ::) ), when we lost power unexpectedly. It wasn't a scheduled load shedding (rolling blackout), but the main wires outside our house had gone to hell (thankfully got replaced this afternoon by the electric company).

Anyway the UPS kicked in, and then eventually it lost juice and the computer turned off without shutting down properly while furiously writing the HD.

All this happened as I slept, and the UPS beeping didn't awaken me till it was too late.

When I turned my computer on later, it kept crashing etc, and there were weird slowdowns. HD Sentinel reported the error so here I am.

The messed up thing is that after this whole incident, last night, after backing up my data, when I decided to do a slow format, I ran into another issue. After 3 hours the slow format was at 73% (it is a 1.5TB Seagate, but I am not sure if it was that slow because of the size or the errors), when we suddenly lost power again unexpectedly.

The UPS is a dry battery (I am not using the wet battery UPSs' anymore because of the smell), and gives only 15 minutes of backup.

So yea I was praying the power would come back for the whole 15 minutes.

It didn't.

After the power came back at six in the morning, I woke up, turned the computer on, and the Windows startup CD was taking a really long time with the harddrive. I had to delete partition and do the slow format again. Amazingly it reported no hard drive errors.

The electric supply company people came by this afternoon to fix the burnt lines. Apparently a crow had landed on the transformer, causing it to blow, and the lines to burn. This had been the problem. It was why the power kept going I guess...

They finally replaced all the lines a few hours ago.

While I did the slow format this morning, I still decided to go with chkdsk /r as Scotty2Hotty (don't get excited Scott, it is just a prowrestler's name) suggested.

It has been an hour and it is still stuck at 50%, which it went to from 0% in half a minute.

A quick Google search reveals this is normal.

Fingers crossed, though all of this is covered in the warranty. Unfortunately that will be a hassle still, and who knows what Seagate will hand me back instead. I'd rather take my chances with this. If it doesn't work out, I can still go the warranty route.

Good luck. My advice is to stop downloading all that porn, it is probably what caused the problem.

Not sure about the formatting problems, but the crashing after power loss probably has more to do with corruption than bad sectors.

My system-drive crashed and burned because I dropped something on the power-strip switch (interrupting power abruptly).  It became unbootable, so I had to reformat it, and reinstall Windows.  Not long after, I was getting hardware faults reported by event viewer.  Chkdsk revealed bad sectors.  I didn't want to go through the whole pain of starting from scratch again, so I imaged the drive and swapped it out.  All is well still.

My guess is that Pug is going through the same kind of downward spiral here.  Don't know why a power failure would precipitate it, but there it is.

My help-board thread on the nightmare.

Edit:  Oh, and the rest of the story.

When you do a full format, the disk is scanned for bad sectors.  If any are found, they are marked and not used by the file system.  If you do a chkdsk /r, this same thing happens with the addition that the system tries to recover any data in the bad sectors.  There is no need to reformat to avoid the bad sectors.

But yeah, if I had a drive that started getting bad sectors, I would be prepared to replace it.

Well, I am dual booting XP and Win 7 (was using 7 on my laptop but Vista on the desktop) now on my desktop after all the formatting and stuff, which revealed nothing.

Everything is running beautifully now. Hopefully it will stay that way.

By the way, I was wrong, Win 7 isn't just Vista with a new service pack. This is awesome. I thought maybe my corei5 was making it so incredibly fast on the laptop, but even the core2duo on the desktop is running this thing very very smoothly.

Could it be the switch to 64bit? Or perhaps that I hadn't formatted my Vista in years.

Normally OSs do get significantly slower as time passes, but I have noticed my Win 7 laptop is still tip top... and the OS is now doing quite well on my desktop.

Regarding 64 bit... the main difference is that it allows more and better memory utilization. Is that the only difference between that and 32bit?
