How do I fix bad sectors on my hard drive without an os?

by lizzyD52 / March 9, 2009 10:16 AM PDT

I've been trying to install linux. I wiped the drive but installation is halted. I've figured out the reason is some bad sectors on the hd. How can I fix this with no operating system?


So far I've downloaded some support software for the Western Digital internal hard drive, but it doesn't solve my problem. Any ideas?

Which diagnostics program?
by Steven Haninger / March 9, 2009 10:37 AM PDT

Run the one that writes zeros to all locations. It will disclose problems with the media. Depending on the model of the drive, it's sometimes possible to remap bad locations to spares but this isn't recommended as a permanent solution.

It's called data lifeguard and comes in several flavors. With no OS you need to get the bootable floppy or CD version. But, you need to download that on a PC with an OS, of course.

That's the program I used. I was hoping for a more permanent fix, though.

only permanent fix is a new hard drive

hard drives reserve some space for spare sectors but a bad sector can't be fixed -- they can only be replaced with a spare. if data lifeguard can't format your disk and an OS install to successfully, a new drive is the best solution.

you could try to partition the drive to skip over the bad sectors and just ignore that partition but you're flirting with a hard drive failure.

Yes you can Run WDM Disk Management to isolate or repair your disk from bad sector.

SpinRite

Those hardware manufacturers software programs will only prepare it to a factory state, it might fix some bad sectors but usually not.

The best software I found that fixes bad sectors is Steve Gibson's SpinRite program, if it can be fixed it will fix it. It doesn't matter what type of file system you have either. With raid you have to do some extra work before it will work.

It is pricey at just under a $100 however it has been worth it for me as I saved or prolonged the use of drives over the last 10 years.

Fixing Disk

I have used Gibson spin disk over the years. I wont go into a long jibe but, if Chkdsk does not/wont fix that disk so you can use it, my experience has been a new disk is the only way to go. However, if you want to court disaster keep using the fixups. Yes a disk does come with set aside area for relocating bad sectors but a disk degrades to the place that does not work well.

Do yourself a favor, get a new disk

New Disk

In reply to: Fixing Disk

Agree with you buddy.

Should have clarified.

A new disk is required even if spinrite does fix it.

After spinrite most drives last another 1 week to 6 months before another pass with spinrite or just dying, I've had a few last years however this is not typical.

Spinrite will fix the problem as it is now, however unless you were lucky enough to just have a short run of disk sectors go bad it'll get worse and usually exponentially so you'll need a new disk soon.

Get a new drive, use spinrite on current drive, transfer all files to new drive.
