I guess you could give it a try just to see if the drive still runs under IDE. When you formatted the drive was it for NTFS or FAT32?Should I attempt switching back to IDE and see if it recognizes it?
Normally no and it's usually just a case of making a change in the bios. I know you had to use a guide but i think that's because the os was originally installed under IDE. I guess at this point you'll just have to see what happens if you switch it back but ideally you should have both drives on the AHCI enabled ports and the DVD-ROM drive could be inserted into the ports which are still IDE.Would switching it back to IDE possibly cause any problems?
Can you test the drive in a different machine?Welp, tried multiple ports, as well as switching between modes (switched back to ACHI with no problems) and no luck. Only other explanation is drive failure. And after reviewing abunch of different internal HDD lately I can't say I even trust a brand anymore. Both Seagate and WD seem to be getting all kinds of hate lately for there quality in drives. I don't suppose you have any recommendations? I barley even filled half of this drive, but I plan on using my new one for a bit more storage. So anything in the 1-2 tb range should do.
