I have to agree with you I have Hardy though I do see many improvements
this is a major concern but it appears this is not resolved. I have gone
through 3 drives already but sadly Ubuntu cannot get this fix they will
loose user's hard drives for laptops are not cheap.
What is sad is that Hardy is very smooth boot times are great my laptop
does not get hot like it did and then this nonsense with the hard drive
still rears it's ugly head.
So if you do see anything that I missed or did wrong please advise me if
I am correct sadly I will go back to Windows XP which I really do not
want to.
Maybe I am not doing this right but here is my stats
Load_Cycle_Count 0x0032 084 084 000 Old_age Always - 32851
Power_On_Hours 0x0032 100 100 000 Old_age Always - 378
You can get the average per hour by the following division:
Load_Cycle_Count / Power_On_Hours
That works out to 86.907407407 YIKES !!!!
Just in case I did it wrong I will post my entire results
