3 of 4 USB drives only partly recognized.
Win10-64-Pro-1709
This just started yesterday. I have 4 portable USB drives: Toshiba 2 TB Seagate 1 TB Samsung SSD 1 TB WD Elements 1 TB The Toshiba is permanently attached and is used for files-folders differential backup nightly. The other three are rotated for periodic full image backups. Now none of the other three are fully recognized by Windows. When any of them is plugged in, Explorer does not show it. The removable devices icon, when right clicked., shows the device, but not the drive name as it used to. All three work fine on my Win-7 machine, and I have run diskchk /f on them. All reported no errors. I have tried them in the same USB port to which the Toshiba is usually attached. I have tried removing the USB devices with Device Manager and allowing Windows to reinstall them on reboot. I have of course tried shutdown and reboot. I have tried having one plugged in while rebooting, so it is attached at boot as is the Toshiba. Kind of at my wit's end here... -dan z- -- Someone who thinks logically provides a nice contrast to the real world. (Anonymous) |

Ed (very logical, unlike the real world) (:_ +1 I have run into the no drive letter many times, even with eSata I have several portable HDs that I move between Win7 and Win10 systems. Every now and again one system will complain, saying that the disk needs scanning before use. So I tick yes, and 10 seconds later all is ok. Except that when I then move it to the other Win system it needs a letter assigning. Just why, I don't know; but it's such minor trouble that I just do it. Ed |

I recently introduced three new portable HDs to a Win10 system, one after the other, unplugging them after letter-assignment. The system gave them all "G". When I have time I'm going to plug them all in together. I think we can all guess just what will happen; the first will go in as G, the second two will be unassigned until I assign them in Disk Management, and then they'll be H and I. That is, of course, unless other USB ports are carrying other drives at the time. MS have my sympathy over this. I've tried to work out something better, but I can't. It's a devilish situation to try and cater for all the possible permutations of USB-assignment, and I think MS have the least dangerous one. Ed |

Ed Used every night in an unattended batch on a single SD card to copy files off. For my reply just modified for several HDDs. On Win 7 problem was removing SD for some reason and then replacing it occasionally assigned different drive letter so following batch commands would not work. The "XX" let the batch skip commands if SD was not present. -- Zaidy036 |
