I deleted an old USB Stick on this Windows Server 2012 machine, formated it and then used Veeam Recovery to turn it into a Recovery Medium. Veaam also formatted the stick once more and I verified it had the recovery system on it. Weeks later, 1 or 2 server restarts involved, I wanted to have a look on this Veeam Recovery USB Stick again. Knowing what was on it, also remembering the old file structure on this stick, I plugged it in and... ...Windows Server then showed me the old files and folders on this USB Stick for about 5 Seconds, which then turned into the actual file structure. @_@ I copied and deleted some files on it, which was no problem...but I decided to not to use this USB Stick as a Recover Media. As I have experienced this for the very 1st time...Id guss its either a Windows Cache phenomenon or more likely a defective USB Stick / Chip on it ?
I've got a 256GB M.2 Sata that I have been using in an external USB3 Case. Being fast the original plan was to use it for OS deployment, also storing all drivers, apps, benchmarking sw, etc. I found that not all PC's like it as a boot device (ie, lock up at post). There was also a board where during deployment the usb drive would randomly disconnect. I now use this drive just to transfer files. Never an issue on any of the pc's at work. I do find that sometimes at home when I move the files off the drive, when I then plug it in at work the files are still there & I then just delete them. My home PC is an old Z68 with the NEC USB3 chipset...
