Comment 366 for bug 59695

Hi Akshay,

I noticed that the "ugly" fix posted earlier didn't work too well for me either, perhaps my machine wasn't detecting whether it was plugged in or not. I simply put

     hdparm -B 254 /dev/sda

into the ugly fix file suggested, instead of the longer version which detects whether the machine is plugged in or not. I then did the install procedure as suggested, and It seemed to correct it for my machine. Does this command:

    sudo hdparm -B 254 /dev/sda

do anything for your machine at the command line? Have you tried changing 254 to 255? For some people that seems to help. Also, perhaps trying changing sda to hda, or depending on whether it's a second drive, change it to sdb or hdb.

If this doesn't work, I'd suggest going to the hard drive manufacturer's web site, and downloading their hard drive configuration tools. You can determine your hard drive type by going to System>Preferences>Hardware Information. My hard drive type is located under 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller. It's a couple of levels under that, but it shows up as a Fujitsu MHY2160B, and below the drive lists my partitions. Your mileage may vary, and you'll probably be looking for XXXXXX SATA XXXX Controller or XXXXXX HDA XXXXX Controller.

Usually the utility for configuring your hard drive available from the manufacturer is available as a bootable CD that you burn and boot to. You simply adjust the parameters from an screen there, following the directions they give. If hdparm doesn't get your machine to respond, this is what I would recommend.

My Dell also has an adjustment screen built right into my computer's bios, but it doesn't seem to do much, as the only options are bypass, quiet, and performance.

Let me know if using the hard drive manufacturer's utility to adjust hard drive parameters works. If not, we'll go from there.
