you say this is happening on several PC and with several SanDisk SSD. How many exactly? we ahve never seen any reports here with anyone else reporting this issue.
If the suggestion below does not work we would need some more information about the computers you are seeing this issue with. We need make, model, SATA chipset, BIOS version, SATA config, SATA driver for the hardware what cloning apps you are using and versions.
That said if a drive is seen in the BIOS but not by cloning software it is usually an issue with the partition. Try using a windows installtion disk and use diskpart to clean the partition.
- Insert the windows 7 DVD into the DVD drive.
2.On the disk selection screen, press SHIFT+F10. A Command Prompt window opens.
3.Type diskpart, and then press ENTER to open the diskpart tool.
4.Type list disk, and then press ENTER. A list of available hard disks is displayed.
5.Type sel disk number, and then press ENTER. number is the number of the hard disk that you want to clean. The hard disk is now selected.
6.Type det disk, and then press ENTER. A list of partitions on the hard disk is displayed. Use this information to verify that the correct disk is selected.
7.Make sure that the disk does not contain required data, type clean all, and then press ENTER to clean the disk.
All the partitions and all the data on the disk is permanently removed.
8.Type exit, and then press ENTER to close
- Continue istallation of Windows OS by using automatic partitioning scheme rather than creating partitions yourself.
