My hard drive in my computer is dying. This morning when I turned my computer on it complained that there wasn't a boot drive and my hard drive wasn't showing up in the BIOS. I turn the computer off and on a few times and it finally recognized the drive and booted. It is still running and I'm typing this on it right now, but I'm afraid to turn it back off. I ran HDTune on it and it reported several bad sectors. So I want to replace the drive today. I went to my local computer shop and they had a few drives in stock, I'm looking at 1TB drives. My options are basically a Seagate Barracuda, another WD Green, or a WD Red. Now there is no way I'm getting a Seagate because their trash, so that just leave the WD Green and the WD Red. However, the shop owner said that the WD Red drive can't be used as an OS drive. He said that WD put some kind of software on the drive that makes it only work as a data drive and it will only work in a NAS. I also remember reading someplace, maybe it was even someone on here, saying that the Red drives don't have the normal error correction that normal hard drives have, instead it relies on the error correction of the RAID controller. So if you use it as a standard hard drive and there was an error like a bad sector all the data would be lost but a normal hard drive would correct the error itself and keep working. But the Red drive was actually $25 cheaper than the Green, so I'd prefer to get that if possible. But I want to get the facts straight about them first. The shop owner said if I bought the Red drive he wouldn't take a return if I couldn't get an OS installed on it and I don't want to risk data even if I did get it working so I need your advise.
