You're doing RAID arrays wrong

Date: September 10th, 2025 12:23 AM Author: jet-lagged soggy affirmative action heaven stop doing it in the BIOS and thinking you're safe because you created a mirror raid. That doesn't actually work, because if data gets corrupted on one of the drives, your motherboard has no way of knowing offhand which drive has the good data. If you sync the array, and one drive has fucked up sectors, it may just copy its fucked up corrupted files onto the good drive, overwriting your "backup" copies.
There's also no perfect way to do this with only two drives. You need a third drive in the array that can [hopefully] tell which of the two other drives is fucked up, and vice versa. But your motherboard can't do that, only software can do that HTH. Leave that shit in AHCI mode in your BIOS and never use "RAID" mode. |

Date: September 10th, 2025 12:33 AM Author: Shimmering painfully honest school You've made the implicit, fundamental puppyn00b error of thinking RAID is a backup. It's not, and no one but you thinks it is.
RAID is /part/ of a backup solution. I use Crashplan for rolling backups, so if something gets corrupt, it's no big deal. At some point a few years ago, I'd deleted some contracts off my computer and was able to retrieve various versions of them with that.
RAID is so I don't have to restore from Crashplan unless necessary. |

Date: September 10th, 2025 12:46 AM Author: jet-lagged soggy affirmative action heaven If the data was already corrupted when you backed up the drive, your backup drive will only contain corrupted files. This is why servers use ECC RAM btw. (http://www.autoadmit.com/thread.php?thread_id=5771556&forum_id=2Reputation#49249498) |
