Earlier, I reported about my problems using an Intel SSD 520 Series 180 GB disk. Friday I was told by IBM that the original disk should be thrown away. And as there no longer was a problem if I bricked the firmware, I decided today to try to install Intel firmware to replace the Lenovo firmware currently on the disk.
I searched the Intel site for firmware, and found issdfut_2.0.4.iso (aka Intel SATA Solid-State Drive Firmware Update Tool) which according to the site should contain the latest firmware for SSD disks. I inserted the broken disk in one of my spare laptops and booted the ISO from a USB stick. The disk was recognized, but the program claimed the newest firmware already were installed and refused to insert any Intel firmware. So no change, and the disk is still unable to handle write load. :( I guess the only way to get them working would be if Lenovo releases new firmware. No idea how likely that is. Anyway, just blogging about this test for completeness. I got a working Samsung disk, and see no point in spending more time on the broken disks.
