Getting Error Message When Booting With External Hard Drives Attached
Sep 11, 2015
Since upgrading to W10, My puter will no longer load when I have my external hard-drive attached. When I switch on my puter, I get a black screen with the message 'Non-System disk or disk error, Replace and strike any key when ready'.
When I reboot with the ext HD disconnected the reboot is fine and W10 loads no problem. If I reconnect the Ext HD while the puter is up and running, no problem, and both the computer and now attached external hard drive function perfectly.
I have tried reformatting the external hard drive but I still have the same start-up problem when the ext HD is attached on start-up.

I recently bought a Dell XPS 8700 running Win 10. I still have my old computer, a Dell Inspiron 530 running Win XP Home 5.1.2600. I made a clone (i.e., a bootable drive) of the old Inspiron 530 hard drive on a Seagate Expansion portable drive with a USB interface. I want to plug the Seagate drive into my new XPS 8700 and boot from the Seagate drive, thus starting up and running Win XP and accessing all my old apps and files. When I am done, I want to restart the XPS 8700 and start up Win 10 as usual. My XPS 8700 with Win 10 is running just fine.
My purpose is simply to physically throw away my old computer and yet continue to use my old computer in a virtual sense by "hosting" the same functionality on my new computer. I realize I will need to restart my computer when moving from Win XP back to Win 10, and I realize I can't within one environment access files in the other environment. My immediate problem is I cannot get to a screen that lets me boot from my Seagate drive. (I might run into other problems after that.)

My Maxtor external hard drive is not showing under This PC, but is under Device Manager. Updating the driver comes back as driver is up to date. Changing Bios setting between UEFI and Legacy do not make a difference. Using a different USB port does not make a difference.
I can get full access to the drive if I boot up LinuxMint from a USB stick.
Microsoft says this is a manufacturers driver problem.
Acer says this is Windows problem.

With Win7 I used to open one external drive, then through My computer locate the other drive. I would have each drive on its own window. I could then select relevant files on one drive copy and paste into the other drive. With Win10 if I click on File explorer I can open one external drive, where can I locate the other drive to put in a separate window. If I click on the other drive, it just opens it in the same window. Win7 and previous versions used to be so simple.

My HP Pavilion all-in-one computer does not recognize my Seagate external hard drive after I installed Windows 10. Everything worked well with the Windows 8 but neither system will recognize the other once I upgraded to Windows 10.

Windows Search returning no results on one of my external harddrives. I have already:
Tried indexing the HDD and rebuilding.Non-indexing and rebuilding.Indexing only specific folders on the HDD and rebuilding.Specifically disabling indexing for this drive in the drive's properties.Checked that I have the appropriate permissions on the drive (they are identical to my other HDDs).
Crude example of my problem:
I am looking for the following file, A:Example est.txt.I am inside the A:Example folder.I search for "test", "*" or "txt".It says there are no results.
And it says "no results" instantly - it doesn't appear to even try.
I do not have a second drive with sufficient space to move the contents to do a format - so I'm looking for non-destructive solutions.

My PC performance with Windows 10 is very good except when it isn't
One of the things that is perplexing me is that my external hard drives seem to be impacting my startup performance. Following start up Task Manager performance tab shows one of my external drives (G) working at nearly 100% and the noisy disk drive suggests that it is working hard. The disk transfer rate also indicates movement between the PC and the drive. This is despite Drive G being used only as a storage/backup device with no automated actions configured. Yesterday Drive G became very hot as a result.
If I disconnect Drive G, my second external hard drive Drive F takes its place and task manager shows the same activity as previously shown on G. If both drives are connected F shows no activity.

So last night I finally got around to putting windows 10 on my ssd and swapping windows 7 to the back burner on my computer. I would like to point out that I am fairly tech savvy and have built and repaired my fair share of computers in the past three years,this should have been routine. But sadly me being the bright and clever bastard I am not only forgot to specify an os specific partition copy so the hidden files would be copied but also forgot to format my ssd completely to remove bootsect before transferring windows 10 to it...
So now I have a little bit of win7 in win10 and vice versa so now in boot manager the operating systems are backwards...and that's not even the bad part,neither of them boot properly, they both load but not further than a base colour with a version number in the bottom right(one slip up and I'm in over my head) so I tried just booting my ssd no other harddrives connected and now it throws a bcd error...until I plug it into my vista build and then it runs buttery for the hdd it's the opposite no dice on my vista build but all clear on my main build(with no other harddrives that is)
I would like to resolve this with minimal data loss (most of the data Is on my win7 drive but I don't want to reinstall).

My external hard drive is showing an error.
G: is not accessible.
The disk structure is corrupted and unreadable.
How to fix it without formatting it? Have a lot of file on there that I'd like to recover if possible.

My issue is, I have a laptop with windows 10 home installed (all legit), I wanted to replace the laptop hdd with an ssd and put the original hdd in an enclosure to use as an external hdd.
This all went well put the hdd in the enclosure and went to boot windows 10 from the now externall hdd and end up getting an error saying unable_to_access_boot_media, I have had automatic repair come up but does not fix the issue.
The external hdd uses a USB 3.0 connections so as suggested in another post I turned the BootDeviceFlag to 0x14 to load the USB 3.0 drivers early but this has not fixed the issue either. Where to go from here?

Inserted my new SSD to a SATA3 port and, next to my HDD 1TB, and went for a clean install right away. The system installed without problems (wiht the old HDD still attached), then i booted up the system (was a bit weird, because two versions were showing, however i formatted the old windows partition) and installed my programs. I saw that a 110 MB of data were still sitting on my old partition where the Windows 10 was earlier. Tried to delete those files but could not. However I shut down my pc and wanted to boot up again. Then it showed me a screen with "select proper boot device or restart computer". I went to BIOS to see if my SSD was set to primary boot device, but it was. But when i manaully select the boot device, my SSD, after starting up the computer, it boots into Windows and is running normally.
Can it be that there is no boot partition on my SSD and it wants to use the boot files from the HDD?? I also tried to unplug the HDD and boot up, but the same massage was showing up. But when i select the boot device manually it works.

I recently upgraded my PC to windows 10 and every since have been unable to access any USB external drive. The laptop picks up the drives and acknowledges that they are there and working but they do not appear in file explorer. I have looked in disk management and the drives are there and healthy. The USB ports work 100% as i have plugged in keyboards etc to test and all the drives i've tried work with other computers. I've reinstalled windows twice. Ran various disk cleanup utilities, checked for hidden drives etc.I need to upload video files to my laptop to edit for work.

I just upgraded from Windows 7 PRO to Windows 10. I notice that my external USB 3.0 drives can't be found. Before the upgrade it was ok. The only external device that does show is a Sandisk FIT USB 2.0 stick.

This morning I tried to login to my windows machine, windows 10 pro, intel i5 3.30ghz, 12gb RAM, 2TB HD. and kept telling me password was incorrect. I then removed windows password thru other admin user, and now all external hd's except for c: drive all lecked by bitlocker. Never installed or activated it.
I have 2 internal sata drives and 2 usb drives locked. I have gone to control panel, bitlocker, and tried to unlock drives, tried to do a search for key id on pc and nothing is found. My raw files are in the backup drives.

In recent weeks, it has become impossible for me to safely remove my external drives. (Mostly, I use Western Digital Passports, Passport Ultras, etc).
I am using Windows 10.
I close all of my programs and folders. I get the "busy" message and to try again later. I run Unlocker on the drives, and Unlocker shows no activity or actions that I can take. I bring up my task manager and nothing is running. I try to safely eject from the WD utility and it doesn't work. I try to eject by going to my computer, right clicking on the drive, and ejecting from there. Sometimes I simply wait for half an hour, read some articles, try again. I get the same "busy" or can't shut down message.
I read online that I could try to Device Manager, click on the drive, and under policies select "Optimize for Performance." However, the computer must restart for changes to take place, and when i've tried, I get stuck on an infinite "Restarting" screen.
I read somewhere that I can try to empty a hidden recycle bin on my external, but I can't seem to reveal it?

My new windows 10 only sees my PC - when searching for my files in Explorer, it cannot 'see' my two external drives when I plug them in. I've looked in Device Manager and they are not showing in there either. How can I tell Win 10 to access my external drives?
I thought Win 10 would automatically spot my external drivers the moment I plugged them in? Then it would go search for and install the appropriate drivers - but it isn't doing that..

Okay, I have Windows 10, and Macbook. My PC, have 2 hard disks, one is of 500 GB ( Seagate ) and one is 3 TB Western Digital (Black).
Machine is loaded with:
CPU: Intel Core i7-4790K 4.0GHz Quad-Core Processor
CPU Cooler: Corsair H100i 77.0 CFM Liquid CPU Cooler
Motherboard: Asus MAXIMUS VII HERO ATX LGA1150 Motherboard
Memory: Corsair Vengeance Pro 8GB (2 x 4GB) DDR3-1866 Memory
Storage: Seagate Barracuda 500GB 3.5" 7200RPM Internal Hard Drive
Storage: Western Digital Caviar Black 3 TB 3.5" 7200RPM Internal Hard Drive
Video Card: Asus GeForce GTX 770 2GB DirectCU II Video Card
I am planning to Install Mac OS X on 500 GB one and keep Windows 10 on 3 TB one. So is it okay if I will just remove the 3 TB Hard disk, and install Mac OS X on it ? 500 GB hard disk have files of Windows 8.1 already. But it is not my primary hard disk.

After a system refresh of Windows 10 all external disk storage drives, Micro SD and USB are listed twice in file explorer. This is a common problem, reported many times in forums and community support web sites. Could a solution be to reload file explorer. Is this possible and where would I find the download?

I have 2 computers (asus and acer) that came with Windows 7 Home. The product keys are on the side of the computers. The hard drives have been wiped and are blank. How can I update to Windows 10? My guess is I have to download and install Windows 7 with the keys on the computer and then update, but where can I download a copy of Windows 7 from?
