[Kernel-packages] [Bug 499237] Re: Doesn't detect usb flash drive as SSD
I guess this might not be fixable at all. Getting spin speed/SSD or not is done with this command (see http://comments.gmane.org/gmane.linux.kernel.bcache.devel/554): $ sudo hdparm -I /dev/sda|grep Rot Nominal Media Rotation Rate: Solid State Device This is my internal SSD hard drive. I tried with a rotational hard drive attached with USB, but get no information about that. Same with a USB memory stick. This leads me to believe that it is not possible to detect if a USB connected drive is SSD or not, and the kernel assumes rotational drive as default. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/499237 Title: Doesn't detect usb flash drive as SSD Status in The Linux Kernel: New Status in “linux” package in Ubuntu: Incomplete Bug description: I installed Ubuntu 9.10 on a 4G usb flash drive, performed updates as of 19 Dec 2009, and installed bootchart.

[Kernel-packages] [Bug 499237] Re: Doesn't detect usb flash drive as SSD
I am using Ubuntu 14.04, and the problem is still present. And I think this issue may start to gain relevance, since USB 3.0 attached SSDs are starting to appear, and BTRFS to check this parameter for applying SSD mount option. For me, the situation is what I described above, usb3 attached ssd, with my system booting from it, and it is still considered to be rotational. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/499237 Title: Doesn't detect usb flash drive as SSD Status in The Linux Kernel: New Status in “linux” package in Ubuntu: Incomplete Bug description: I installed Ubuntu 9.10 on a 4G usb flash drive, performed updates as of 19 Dec 2009, and installed bootchart.

[Kernel-packages] [Bug 499237] Re: Doesn't detect usb flash drive as SSD
Orson Jones, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11.1 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
