Freeze lock is just a security feature. The BIOS tells the drive to lock it's security, this was introduced to stop virus's and other malware erasing your drive or setting a password and then holding you to ransom to get your data back.
By unplugging and plugging back in after the computer has re-booted the BIOS has long gone and so the drive doesn't get the 'freeze me' command.
The Freeze lock isn't a fault or a problem, it's by design.
SATA supports hot pluging so connecting it while the system is on isn't a problem. Keep the power connector connected to the SSD put just unplug the SATA cable, then once booted connect it back in, you will then be able to do a security erase.
I'm not sure why Linux isn't installing for you.
Hello, and thanks a lot Phil_I for your fast and valuable response
Finally I was able to install PCLinuxOS LXDE in the SSD and do the dual boot.
As per Grub 1 bootloader documentation, is recommended to change your sata cables in your motherboard so the Windows Hard Disk be your first device. In other words to be your P0 SATA device in the BIOS. The SSD must be the secondary device, P1. I have an ASUS P8Z77-VLX motherboard.
Is very important to read this for linux newbies.
1. Download the last version of the Intel SSD Toolbox and install it in your Windows Hard Drive.
2. Please note that the Intel SSD Toolbox instructions to unlock the Security Freeze Lock are outdated. I followed and it did not unlock. Please note that in my previous post I had erased the SSD partitions with Windows 7 disk Management.
2.1 So your advice Phil_I was the correct one.
- I turned off the Desktop, open it,
- take out the SATA cable of the SSD,
- then turn on the Desktop,
- enter in the BIOS, set "Hot Plug" enabled for the SSD (P1), F10 to save the changes and
- when the Windows logo appeared in the Windows 7 startup I plugged in the SATA cable in the SSD drive.
3. I ran Intel SSD Toolbox and this time it was able to do the secure erase in order to have the SSD in the original conditions. It took a minute.
4. This time with the SSD like new, I was able to reinstall LXDE
4.1 Formatting the 223,7GB available and installing LXDE took about 5 minutes.
4.2 Be carefull because the Grub bootloader takes as default for boot device the first disk, the Windows disk, in case of a mistake, Grub will write the MBR and will get "Error Bootmgr is missing" and Windows 7 will not boot.
4.2.1 Use your Windows installation disk but do not reinstall, only repair, it might require various attempts. See this link.
4.3 In my case, it also automatically created the entry in the boot menu to have the option to boot from the Windows 7 drive, and it worked fine.
5. In my oppinion Intel should have an administrator password in the Intel SSD Toolbox so we can have the possibility to modify the bits for "Security Freeze Lock" and "Hardware encryption" among others.
Hope this can help someone else.
