One of my customers is literally pulling her hair out after the second occurrence of a weird phenomenon
She worked all weekend on some Excel (2016) files. These are budget tables with multiple links to other Excel files
These files reside on a Silicon Power Armor 2TB USB drive connected to her ASUS Windows 10 laptop
She saved the files and thought that all was well
The next day she tried to open these same files using another computer (Surface PRO 4) and the files were either missing, or in a version prior to her updates. All her work was lost
Not sure if this is relevant but this SP Armor is on G: with the ASUS, and on D: with the Surface Pro 4 - it screws up the links in the Excel files but shouldn't be the cause of her unfortunate situation - is it possible to force a USB drive to always use the same drive letter on a computer e.g. G: ?
I suggested that to protect the value of all her hard work that she stop from time to time to save the file under another name to manually create different versions
Tonight she called back with the same situation : the work she had accomplished yesterday had once again vanished
The weird thing here is that yesterday she made a copy of the folder containing her files onto another USB drive as a precaution
Just to be clear : she copied this folder from the SP Armor over to the other USB drive
Today the SP Armor doesn't contain the result of the hours spent yesterday : the files are either missing or they don't contain yesterday's input
She connected the other USB drive and discovered that this second drive contained everything that has disappeared from the SP Armor (Phew !)
So, it would appear as if something is causing the SP Armor to rollback from the latest situation in which it was and lose/erase the previous day's file updates
Any ideas why or what could cause this to happen ?
