One of our Dell Latitude E7240 exhibited strange mSATA SSD behaviour. Disk requests didn’t complete on time. This computer ran the A13 firmware.
The case was eventually solved by upgrading to the A21 firmware executed from an USB stick as the mSATA SSD was unreliable at this point. Apparently, the A18 firmware corrected some mSATA port settings. Also, this was a good opportunity to rid us of Intel’s SA-00075.
This isn’t the first case where disk behaviour suddenly changes to the worst on Latitude E-series laptops, only to be rectified by a firmware upgrade.
Over the last few days have I experimented with UEFI and GPT in VirtualBox 4.3.26. The goal was to multiboot various operating system, in this case Windows 10 Enterprise Technical Preview 9926 x64 and FreeBSD/amd64 stable/10.
First, I thought of persuading the UEFI firmware to always present its boot menu. It sure beats remembering to press F12 each time I want to boot a different operating system. This proved impossible for a number of reasons.
Next, I came across The rEFInd Boot Manager. After a quick glance I saw this is exactly what I want, a UEFI boot manager. Continue reading UEFI, GPT, Windows 10, FreeBSD 10, and rEFInd
I find it curious as to why most, if not all, SSD manufacturers are unwilling to disclose the physical disk, the page, and the erase block sizes selected for their SSD products. Such crucial information should be readily available to guide us, the more advanced users, to properly align our partitions and configure efficiency in our filesystems when using operating systems other than Microsoft Windows.
