    Question Alternative to Palimpsest utility?

    I recently threw an IBM/Lenovo (Samsung, actually) brand SSD in my Thinkpad X41, and upon boot, Palimpsest reported it had some appallingly high number of bad sectors... Something equalling roughly 3.7 gigs or so.

    I know this to be untrue, and have read a number of posts/threads on false positives from Palimpsest, especially with this model hard drive. (Also, the drive is brand new and has never been used.)

    Anyone know of a good alternative to Palimpsest for checking for bad sectors and such, so I can do a VALID scan of this drive?

    Can you install libatasmart-bin and post the output from

    Code:
    sudo skdump /dev/sdX
    with X being your SSD.

    This is what I get. I patched libatasmart to also display attributes 175 through 183. Those are (Samsung) SSD specific. I got the meaning of these attributes from Samsung Semiconductor. And technical specs of other Samsung SSDs.
