Not a computer guy. Afraid I screwed the pooch on this one. PSU failed. Replaced it. Could not get boot or post. After removing devices, cards, etc nothing changed. Source of infinite knowledge (Internet) said reset CMOS, so I did. No change. Went back and checked everything for3rd or 4th time & found hidden from view under ribbon cable the 4- pin CPU power connector not plugged in tight. Fixed that, boots but now I get "raid array: failed bootable: no. Anyway to fix this without losing everything on hdd's? Eta: XP multi-media edition |

You blew your LUN when you cleared the CMOS. This could get costly...  If it was a mirror you can plug the drives into another PC and get the info. It it was a raid0 stripe, you are likely in trouble unless your RAID controller has a rebuild option, but not likely. |
| Not home now but pretty sure on stripe 1. Tried TestDisk but have not got it bootable yet, think I need to put it on a dos boot disk. May not help me anyway. If no way to restore without saving anything and losing everything then I guess I need to figure out whether (and how) to restore as raid 0 with striping or some other configuration. |
| Do you actually have a RAID card installed or are you using the chipset software RAID? If it's a software RAID it will probably work by just setting it back up the exact same way you had it before. I used to move a 4 drive stripe from one machine to another that both had ICHx chipsets without a problem. |

It it was a raid0 stripe, you are likely in trouble unless your RAID controller has a rebuild option, but not likely. If you can't tell the raid card to assemble an array (instead of creating one, then it's a pretty horrible RAID card. Of course, it sounds like he's using an onboard RAID, which may very well be just that horrible. RAID implementations that don't maintain on-disk array info (metadata, "config on disk", whatever the individual vendor wants to call it) should be outlawed. |

im fairly certain this had nothing to with you clearing cmos.
ive unplugged ide / sata cables on a raid and it fubared the raid. if rebuilding it doesnt fix it. your looking at data recovery . if raid 0 you most likely wont get it back Posted Via AR15.Com Mobile |

| Did more fiddling. No matter which sata port or cable used one hdd always registers and one never does. Hdd failure or could it be something else? Considering other options but for raid 0 would replacement hdd need to be identical make/ model/ capacity or only same capacity? Understood that barring $ending both hdd's for data recovery my data is gone. |

Fantastic! Disconnected both drives then tried each by itself. Both spun up. Switched data cables & system booted up, everything normal! No data lost at all! Guess sometimes it's better to be lucky than smart! Of course if I had been smart in the first place... Speaking of smart I'd better start a thorough back- up. Bought a new hdd in anticipation of replacing my "bad" one. If I can find space in the case I might make use of it otherwise it gets returned. Advice on that? |

Get the data off and install new drives. Also run some tests on the sata card and HDD with a clean windows install once your data is secure. Make sure the board is not bad before trusting it. If it is just the drive shoot a hole in it and move on. But a bad board can come back to haunt you. Consider a cloud storage provider, they are pretty cheap.
