Drive boots multiple times when internal but once from USB

Hello,

I have a problem with my 2011 Mac Mini, High Sierra.

When I use my drive as an internal drive, my Mac needs to reboot multiple times (1-3 mostly), but when I use the same drive and use it as an external via USB it boots just once.

Multiple boot-ups only happen from a cold boot up. Once it goes to the login screen and I log in, turn in off, and then on again, it boot ups normally.

I have reset pram, SMC, and all that stuff.

I reinstalled my os multiple times now. Now I will try to install it fresh from the bootable drive.

Also, I have swapped the flex cable from the original to a replacement one from aliexpress. I do not have the original one anymore, so I cannot test if it is the problem.

I would really appreciate some help with this matter as I want to sell it but I do not want it to fail a new buyer.

Cheers!

You likely have a worn or damaged cable. Follow this guide Mac mini Mid 2011 Hard Drive Cable Replacement to get the drive out of the lower bay. If you have a dual drive and the boot drive is in the upper bay follow this guide Installing Mac mini Mid 2011 Dual Hard Drive Kit

Are these legit? They're quite pricey. I have tried another flex cable (alliexpress one) and the problem continued.

I think I will try to get a lower specced Mac mini or broken one for parts and try to get the cable this way.
