RAID 5 corrupted file
Posted: Sun Dec 16, 2018 8:30 am
Hi,
I have Intel Rapid Stroage RAID 5 (on mainboard)
My raid disks:
1) 2 TB
2) 2 TB
3) 2 TB
I wanted to renew my Raid disks. (for malfunction)
I do:
1) I changed to 1. disk to 4 TB new disk and rebuilded raid.
2) I changed to 2. disk to 4 TB new disk and rebuilded raid.
3) That's how I've worked normally, I've formatted the old raid disk (2 TB) (non-raid)
4) It's been 10-15 days. I changed to 3. disk to 4 TB new disk but there was a "failed" error while processing for rebuilding.
Then the raid disk became unusable.
When I looked at it later, I found out that it was bad sector on 2nd disk. I guess that's why he couldn't do the rebuild.
my raid 5 layout:
1. raid volume: raid_1 (700gb) strip: 64kb
2. raid volume: raid_2 (2.9tb) strip: 64kb
Ofset: 0
Left Async
R-Studio with "missing disk" as a complete scan of the disk.
I have three NTFS partition and I founded three NTFS partition.
1. and 2. partition no problem, every things okay.
But 3. partition is problem: I see my files, but after recovery, the file contents are corrupted.
picture, video, music etc. corrupted.
What is problem ? How do I fix this problem?
Thanks.
raid build layout:
example corrupted image: Check Raid consistency is problem but it reads and finds files and partition.
Some bad sector have a read error but the bad sector is not on the third partition.
