how to isolate raid corruption
At the risk of starting a long thread, I need help troubleshooting my Pc'
raid corruption problem. apparently my PC with Asus K8n-vm csm gives that hassle of corrupted raid. I heard it can be BIOS, driver, mainboard, PSU, RAM, even hard drive, ... I have Kensington DDR, hard drives are Seagate SATA I suspect the ps is a potential occasional culprit as the chance of corruption increase with hibernation. But then if I leave the PC continuously on for a couple of days, I will have raid corruption also often prior to Raid corruption showing up in the startup post, the shutdown tends to take considerably longer. the hard drives themselves only luke warm ( I have cooling fan on them) |

how to isolate raid corruption
wow scary stuff...hope the data is recoverable...
I would say start with the basics... make sure the system is stable and then go after the raid. after all since the raid has some software to process , if the system is unstable.. then the raid could be what shows it since all data must eventually end up there. first overclocking anything? if so turn it off second run a good burn utility ..sisandra..memtestx86 maybe I'm sure there are better ones out there next check the raid driver and software for updates sometimes that requires a reformat though ....but what is your choice nvidia had one that was a bear to install on x64 windows PS is possible,Since you are on Asus ..does any of your voltages look lowin pc probe?...of course that won't help with Spikes on the PS ,pc probe won't pick that up.. is it a good brand PS? or a no name? how many watts and are you doing sli or something that requires a big Power Supply? gg wrote: At the risk of starting a long thread, I need help troubleshooting my Pc' raid corruption problem. apparently my PC with Asus K8n-vm csm gives that hassle of corrupted raid.

how to isolate raid corruption
I reckon you have a bad drive - try SMART testing them
using Seagate's utility. Have you checked RAM with memtest86? Bad RAM can cause havoc. Tried swapping the HD cables? If you can afford it, buy another HD and swap one at a time, letting the RAID 5 array rebuild each time (after all, that's one of the best reasons for using RAID 5.) Then use the system as normal until it (hopefully) works ok, returning the faulty drive (which will now be sitting on your desk , if still under warranty. If that doesn't work, you likely have a faulty motherboard, some kind of problem with the RAID drivers or an obscure hardware compatibility problem. Either way, it's not going to be easy to track it down - googling would be your best bet. -- Rob "gg" wrote in message news:zrxpi.47193$Io4.34063@edtnps89... thx for replying. answers inline "Paul" wrote in message ... gg wrote: At the risk of starting a long thread, I need help troubleshooting my Pc' raid corruption problem. ......................

thx. memtest done
cable swaps tried - but I still think something is wrong with the connection for a particular drive I'll be monitoring that drive closely "Oldish Git" wrote in message ...
