Ubuntu load cycle issue on M1330?

Hi all, sorry if this has been posted before, but I spent some time searching and didn't find anything that directly addresses my problem. I'm thinking of buying an M1330, in part because the Ubuntu load cycle problem which has now gained some notoriety has taken a beating to my current laptop. I know there are fixes with using hdparm, but unfortunately I didn't discover the problem until it was too late.

What I'm wondering is, have any Ubuntu + M1330 users noticed the excessive load cycle problem on their M1330? And if so, did the fixes with setting the power management to 254 or 255 work? I simply want to ensure that I can still run Ubuntu on an M1330 without having the load cycle count go crazy.

Thanks in advance.

 

The issue only impacts the hard drive, and a new hd is a whole lot cheaper than a new m1330.

I haven't loaded ubuntu on my new m1330 yet to see (may do that this weekend), but I can't imagine it would respond any differently than any other machine. You should be able to apply the same fixes to reduce the frequency of load cycles.

 

Oh, no, my current laptop is not an M1330, and I was thinking of getting a new computer anyway so the load cycle thing just sealed the deal (not willing to risk it going down at the worst possible time while working, and I don't feel like buying a new HD when I was originally planning to replace this computer soon regardless). But yeah, I don't see why the M1330 would respond any differently to the hdparm stuff, except that I've heard from some people that the hdparm fixes aren't actually working for their laptops so I was just hoping for a specific confirmation that it does on an M1330.

 

using

Code:

hdparm -B 255 /dev/sda

worked for my Inspiron 1420.

I also added the following file so it would be applied after resume:

Code:

chris@red:~$ cat /etc/acpi/resume.d/87-fix-hard-disk.sh
#!/bin/bash
hdparm -B 255 /dev/sda

FYI I have the 5400rpm 250GB drive in mine

 

FYI, this problem isn't exclusive to Ubuntu. When I get my 1400 I'm going to have to do something with Gentoo to prevent the problem from occuring there. From what I've read in different places the hdparm 254 workaround does fix the problem though.

edit: does it matter if it is 254 or 255? I've seen it both ways...what is the difference? (I'm not too familiar with hdparm)

 

I think on some computers setting it to 255 will be ignored because there's some default that prevents Advanced Power Management from being completely disabled.

Has anyone explicitly seen the load cycle problem on their M1330? For more information, see:
