SSD 31 K Bad Question

F1aw1ess · 18 Jan 2010 at 22:26

Hi,

I bought an Intel X25-M 80GB from OC just before Xmas and been having a look round the AS SSD Benchmark thread to make sure mine is performing as it should.

The speeds are all about right but I have a message that says 31K Bad in red, What is this and is it anything to worry about?

It's the offset I believe, it should be 1024, the drive won't be at peak performance with it like that.

Still... nice drive score from AS SSD... no wonder the Intel X25-M scores so well in the Windows Experience Index test. My own Crucial M225 SSD only scores 199!

Is there anyway to correct the offset without a re-install?

This is the third or fourth time I've typed this this week, maybe a mod can add it to the SSD sticky?

Get an Ubuntu live CD, boot from it without installing and run GPartEd.
Using the move/resize option on your partition, uncheck align to cylinders and set it to have a 1MB free space before the partition.
Apply the changes and wait for it to moves things about (depends on write speeds and size of drive, but usually about 15-20 mins)

Windows will then blue-screen on boot, but if you boot from the windows install cd and run repair,with vista or Win7 it will automatically fix things for you and you can boot into windows again.
If you have XP you'll need to use the command prompt option from the Windows install CD and run the FIXBOOT command.

Sorry for making you repeat yourself, I did have a look through the other threads for an answer but couldnt find one.

Thanks

Done exactly as you described and now I have 1055 K Bad :confused:

Sounds like you moved the partition by 1024 but it's moved it using 31k as a reference so it's now 1055 it should have been moved 993.

I think GParted only allowed me to move in MB so the minimum was 1, which is what i chose?

You could image the drive and reinstall windows, then restore the image but without restoring the MBR.

Or simply format and start over.

i had this issue. i sorted it by going into disk management, deleting the volume and setting it as simple volume. nothing fancy was required..

i still feel irked tho that its random write is so slow.

any ideas on this?

Did you uncheck the align to cylinders box? If so Try moving it to 2MB instead, that's how I did mine.
This was a cloned install from my mechanical drive, no reinstalling was required.

Note that the slight performance hit is because the drive was still mostly unused in the first case.
