Motherboard: M2N-SLI Deluxe
3 discs in RAID0: WD 1601ABYS-01C0A0 WD RE2
The chipset the RAID is connected to: NVIDIA nForce 570 SLI
Those three are the only discs connected to that chipset. By the way, can I connect more not ruining the raid?
Windows is on separate disc connected to separate chipset: JMicron JMB363
This raid disc was used for four years for storage and Photoshop templates (intensive use, but not 24/7).
It became hard to read and after force restart (because of lockup) the system did check disc for errors. It found and fixed some. Several times. But Raid Tool from NVidia Panel was not prompting about any errors. I tested each disc separately with this tool and it shows "disc passed the test".
When windows gives an error message with number, I found out that it means something like "the system is not able to reach/communicate with the particular device"
Now is almost impossible to read or write to that disc and I keep that computer of in order not to make things even worse. Though, what could be worse if it will remain unreachable. It contains most of my work for the last few years.
What can be done?
What is the reason?
How to detect the reason why it happened? Maybe then will be possible to make things just a little bit better and save the files.
First of all what did happened? Why raid tool decides the discs passed the test?
May it be the chipset? Voltage? Temperature?
Thanks for any help, situation is really bad.
Raid tools just tell you tat the strip is in tact and when the drives are up and running then they are up so it will pass. Why it fails well one of you drives failed. Ok now for the bad part NEVER store data on a raid o Never unless it is backed up or a raid 10. Raid 0 is fast but every drive you add adds a point of failure. I ran a 5 disk raid 0 for a gaming machine and same thing happened to me 1 drive down evrything gone. But I was ready for this and had nothing important on the raid strip. I suggest going with SSD if you need speed or a raid 1 if what you store is important.
Thank you for a reply. I know well that I shouldn't keep important data this way, but as some of us sometimes, I thought that this time it won't happen to me... Just until I'll be able to buy more and better storage. Just it took four years and failure. The speed was very important for me, that's why I chose the RAID0. Someone said that no raid that will improve the speed will be really secure, so I chose good discs and good luck.
It sounds that this tool is totally unuseful. If the drives pass the test always when up and it is able to see them. But that is not important issue for me at this point.
You say that one drive fails. Then it did this gradually. Maybe I can determine why, which one, and then reverse this process. I feel just a little improvement can save my data.
Are you sure that professional help (that really expensive one) is the only solution?
Maybe there is a software that will try to access my data and save pieces of it?
Well I have heard (I have not done this) If you stick your hard drives in a plastick bag and stick them in the freezer for a while that sometimes they will come back up for a short time and hopefully long enough to get your info off. Make sure you plug everything back in the exact sata slots they came out of. You might first try unplugging the power from all sata drives waiting five min and plugging back in I have had this work a few times myself.

If the data on the drive is important enough to be worth considering data recovery services though, long shots like these may simply cause the drive to run just long enough to drastically increase the data recovery effort/costs and the amount of unrecoverable data.
