Hi, so the hdd doesn’t appear on windows. Like if I go to „my computer“ where all my hard drives are it would not show up. But if I go to the bios I could see the hard drive that was missing and I could enter from the bios on the hard drive and see everything I had on it.
The "My computer" page shows not the connected hard drives but the partitions/filesystems that the o.s. understands and can mount (excluding some hidden reserved or recovery partitions). The BIOS (or UEFI in newer motherboards) can access every connected drive, unless it is completely broken as hardware.
There is another tool in mswindows, the "Disk management". It shows every hard drive (ssd and USB too) with a graphical presentation of the partitions. If you already deleted the partition table, the drive must appear empty. Ext2-3-4 partitions are probably shown as empty or unknown.
I am sure that it is working, because I tried the hard drive on my friends pc. It showed up on windows and worked.
That's good, so you were able to backup your data, I guess.
without the hard drive, ... it worked perfectly fine, but when I connect the hard drive windows would not boot up.
Now i have a complete different problem. The computer starts the symbol of the motherboards appears, where you can enter bios and freezes, when the hard drive is connected. I disconnected the hard drive start up the computer again it works. What I think now is that the hard drive is not working anymore. I bought the hard drive 2 months ago.
It seems strange. I remember a similar problem in the past, where one couldn't reboot into the o.s. when a usb storage device was connected to any usb port. You had to disconnect the USB cable just to allow the power supply unit to start working, and then plug it back into the port. This problem was related to the BIOS, because it occurred for any operating system, Linux as well as windows. It wasn't valid for any computer, as the BIOS isn't the same.
You can try the smartctl command from GParted , to access the SMART information of the hard drive. The drive's firmware stores info about any problem concerning the hardware. I can perform tests too.
You have to boot from the GParted live, open a terminal window and give the command
This will display info about every storage unit that is connected.
Another idea is to try to connect the drive into another sata port of the motherboard, in case that port is somehow faulty.
Even a bad cable or connector can cause problems.
Furthermore, you can try the Linux command
to monitor the kernel's messages during the boot up process. Sometimes, repeated failing attempts for something can indicate potential hardware problems. Even brand new drives can be faulty.
Anyway, with GParted you can format the partition as NTFS directly.
*** It is highly recommended to backup any important files before doing resize/move operations. ***
