    Up and running in no time!

    Acronis cloned my old hard disk and within 1 hour, I was speeding along. It is a little intimidating the first time you do it, but I have now replaced every C drive hard disk in all 5 of our laptops and desktops with Crucial SSDs.

    Good SSD, Bad Disk Clone

    By Dave

    from Phoenix

    Verified Reviewer

    The SSD itself is great. The issue was that the Acronis 2015 did not work on my Acer Spin 3 Laptop. When it got to the place where the PC restarts to do the clone, it never boots. The Acronis 2015 UEFI boot does not work at all on this machine. I have a license for ATI (Acronis True Image) 2017 for 3 machines, and I used that to successfully clone the HDD. After that it all went down smoothly. ATI 2017 uses UEFI also, so it was not that the CMOS is not configured for that.

    Some Dell computers will not accept this drive

    By Jack

    from Sarasota, FL

    Verified Reviewer

    I purchased 2 MX300 525Gb SSD's to put in 2 different Dell All in One desktops. Neither machine would boot from the cloned drive. I spoke with Crucial and they could not help. I spoke with Dell and they would not help. I ended up using the drives in other machines with no problems. Dell locks their Bios to only but from the original drive and would not provide assistance in configuring to boot from the SSD's.
