A:AnswerThis drive will easily hold blu-ray rips. The only thing is that you must format the drive as NTFS or EXFAT. Most likely it will come pre-formatted as NTFS.
Note: You mentioned being limited to 4gb file sizes. That means that your current 256gb drive is formatted as FAT32. If you reformat as NTFS or EXFAT, then the 4gb file size limit will be gone.
A:AnswerThat is a very specific question. You likely have a problem that is unique to that desktop of that WD drive. You should take them to a professional to have that problem diagnosed.
All I can say beyond that is that this drive will work on a healthy Windows 10 computer.
