Centos 7 installer shows incorrect free space - installation

I booted from a USB to install centos7 onto another USB.
However, when I tried to select the installation destination, the installer showed incorrect (very little) free space on all my devices, shown as in the figure below.
Indeed both sdb and sdc are empty, formatted in FAT32 and NTFS, respectively.
sda is the HDD on my PC, which is also only about 50% full.
Anyone knows how this can happen?
installation destination

OK, the answer seems that I have to delete the partition first on the "installation destination" page, although the devices are originally empty. After deletion the devices become completely free and I can allocate the mount points.

Cannot Transfer File to USB (Too Large?)

I bought a 64gb USB to install Windows on since my version of Windows corrupted. When I download the ISO and try to drag it to my USB it says that the file size is too large (even though it's less than 5gb). I was wondering if I was doing anything wrong here and if anyone could help me. Screenshots: https://prnt.sc/lq8dy2 https://prnt.sc/lq8dpx
Thank you!
Edit: Wrong section, was going to delete this post but someone already posted an answer.
Is your drive formatted to NTFS? If it is Formatted as Fat32 and the file size is larger than 4GB it won't work, because Fat32 only supports files up to 4GB.
Try formatting the USB Drive to NTFS and see if that works.

StoreMI - Create Bootable StoreMI greyed out

Situation: New PC Build
- Windows 10
- Samsung Evo 970 256GB NVME
- WD Blue 1TB potato drive
- AMD Ryzen 7 2700X on Asus Crosshair VII Hero
- GTX 1070
One of the main benefits of Ryzen 2, for me, was the StoreMI feature that I really hope to get working. I watched AdoredTV's video of how he set his up, but unfortunately for me, I'm not having any luck.
Greyed Out no option to create Bootable StoreMI
I have gone into Windows Disk Management and made sure the drives are visible to the OS, and they are also visible in File Explorer.
Windows Sees the Drives
If I try to remove fast media, I get this message, and the program closes.
If I try to modify, I get nothing useful.
So...I need some help figuring out what I've done wrong. Could I have something in the BIOS I need to fix? Other? I'm at a total loss.
Edit 1) I may have another clue? One of my greyed out drives is the same drive as the drive that's selectable, and they're "both" in a Tier. Looking at the Disk Manager, it seems my "System Reserved" is for some reason on the NVMe drive when it should have...I would have thought...been installed on the same drive the OS was installed on. I know I didn't tell Windows to do this.
So maybe this is a clue? Can I move the "System Reserved" Partition over to the spinning rust? Would that help?
Same Drive occupies both tiers?
Ok, well AMD customer support never emailed me back. It's been about 48 hours now. Not counting the RTFM email which was useless.
So...I figured...Maybe I'll ask the people I learned the most about this from, either AdoredTV, or Level1Techs. So I went to the Level1Techs forum, and talked to Wendell himself. He diagnosed and suggested a fix (that worked) in about 5 minutes. On my Windows install, I selected the C: (slow) drive to install the OS on, however, the OS set up the "System Reserved" partition on the NVMe drive...even though I never said to do that...it never asked if that's what I wanted to do...It just did it. Effectively nullifying the ability of StoreMI to work.
Why AMD can't do what a youtuber can in 5 minutes is beyond me...and pretty inexcusable. But I digress...
What I had to do was start over. Backed everything up, inserted my Windows 10 installation USB, booted from that, and ****-F10 into a command line from there.
From there, I cleaned all my drives.
Next, I physically removed my NVMe from the motherboard, then went about reinstalling the OS on the slow drive...now the only drive in the system, so it was forced to partition that.
Once that was done, and the OS was completely installed, I shut down the system and reinstalled the NVMe.
Rebooted the system, and I was then able to configure StoreMI easily.
TLDR: If you are doing a new system build, with a fresh Windows install, and want to use StoreMI... My recommendation is to install ONLY one HDD into your system (AMD recommends the install take place on the slowest drive). Complete your Windows install, then install the remaining drive or drives (you can only use two drives with StoreMI), install StoreMI and configure.

Any tool that can confirm if a drive with raw partition is part of a ZFS pool?

I have a client issue that I am working on with a stack of SSD drives and a machine that they were previously installed in. As of now, the stack of drives shows up in a few Operating Systems (Win10, Win7, Mac OSX) as an unpartitioned raw space. I am looking for a simple way to examine the drive and see if it is actually raw, or just formatted for ZFS.
Does anyone know of a Windows or Mac Utility that could help? I've tried a few recovery software programs, that hinted at being compatible with ZFS formatted drives, but have yet to see anything that would indicate if it was actually a ZFS, or simply not formatted.
Regards,
Ed
ZFS is storing at the start and at the end of each device a magic number, 0x00bab10c ("oobabloc", i.e. überblock), reversed for little-endian: 0x0cb1ba00.
So if this number doesn't appear in the device data, you can be sure it isn't used by ZFS. If it does appear, you need to investigate a little further.
For details, have a look to the ZFS on disk specification draft available here, especially page 13.

Unable to install windows from usb flash, I get an error "setup was unable to create new system partition"

I have CD with window 7, I can install windows from this cd, but disc is't mine. So, I want to make a copy on my usb flash drive. I made iso copy of cd disc with WinISO, then I wrote this iso file on my flash drive with "Iso to Usb".
Now I try to install windows from this flash. I have 1tb hdd, I created 100gb partition and get 100gb partition, but when I did the same with with Windows cd disc, it creates 100 gb primary partition and 100 mb system partition.
So, when I tried to install windows in 100 gb partition from cd it installed, but when I tried to install from usb I got exception: "setup was unable to create new system partition".
Why so? Why I do the same steps and I can install from cd, but can't install from usb?
Why usb windows didn't create system partition? And how to fix it?
When installing using a flash-drive perform the following steps:
Step by step instruction:
When the boot setup starts from USB drive
Press Shift+F10
The command prompt will open.
In console type diskpart.exe and press enter. In this program execute following:
select disk=0. Disk 0 is your destination drive, so be careful, all information on this drive will be removed.
create partition primary size=xxx, where xxx – is the size of new partition
select partition=1
active
format fs=ntfs quick
assign
exit
4.exit
5.Now close the setup and restart.
This should solve your problem as it did mine.
Windows usually creates a partition with enought space for the system.
You can try to just take the 1tb HDD as target for installation, and windows will create a partition automatically.
Otherwise, your ISO-Copy may be corrupted.
You could easily download the ISO-Files from here.
Option: Make a Copy of the CD and try with that one?
Having installed windows 7 from a USB drive many times, I've found that if you're trying to install using a USB 3.0 flash drive, then you will get the "setup was unable to create new system partition" error message.
Since I couldn't find any solutions to this at the time, I was fiddling with everything to try to make it work. Eventually I found out an interesting (but strange) solution:
Go through the install process until you get to the screen that asks you to select a partition for the windows installation
Make sure your desired partition is listed, and that its formatted correctly
Unplug the USB drive
Press 'Refresh' (ONCE) to refresh the partition list/window (ONLY press refresh)
Plug the USB drive back in (use the same port as before)
Select the destination partition for the Windows installation, and try to begin the installation
I've done this a few times now on different machines, and it's worked like a charm.
I believe it has something to do with Windows 7 not natively supporting USB 3.0 and/or USB drives with SSD controllers.
Windows is probably seeing the USB drive as the main hard drive, because you have probably made it the first boot device in the BIOS. This will result in Windows trying to install to the install drive.
To solve this problem, make the internal HDD the first boot device, then press F12 or whatever key for boot device selection your BIOS requires.

All partitions missing when copying

I bought a new 320GB SATA hard drive few months ago no recently when i try to copy something to the drive after about 20 seconds the all the partitions in the hard drive suddenly disappears.
The hard drive is not shown in either Disk manager or device manager. To get the HD work i have to restart the PC again.The same thing happens when i try to copy. Even when i play any audio or video after abt 5 minutes i get the same problem.
The drives are NTFS and im running Windows XP.. Xan some one please help me solve the problem??
did you check all the wires ? sounds like a disconnect of the wire somehow ... otherwise the hdd is broken...
The problem was the ide hard drive that i had connected, there seems to be a speed issue. Changing the ide to a different sata drive solved it
