I have 2 internal WD 4TB Red drives set up in raid 0 for photo editing. Two weeks ago I saved 3 psd files at the same time and all 3 ended up corrupted. Osx was running the raid, I restarted and repaired the volume and it worked fine. I converted to Soft Raid after that.
Then the same thing happened last week with 1 very large psd. Softraid reported 56 errors on 1 drive the second time I lost files. I have 2 back ups so erased everything and certified both disks. They both passed and have 0 reallocated sectors. Could this be something caused by photoshop? Im replacing the drive that had errors but I'm a little worried its not the drive and I have some software issue that might do this again.
Thanks

Let me take a guess. We discovered recently that WD drives now have a default setting to go to sleep automatically. This can only be disabled by their WD Utility.
Try downloading it, disabling the sleep setting and see if your problem goes away.

I have had these drives in raid 0 for about 20 months. Wouldn't I have run into this problem earlier? I have put disks to sleep turned off in OSX. I read and write PSDs and other images files to this drive all day. Many times with an hour or more between read writes. The first 3 files that had errors I only had open for about 4 min so I don't think the drive went to sleep in that 4 min.
Wouldn't the raid go offline if one of the disks went to sleep? I haven't seen them ejecting or remounting. Shouldn't the OS hold off on writing data till the disks are fully awake if one did go to sleep? The disks have the same hours of usage(11,000) so if they are going to sleep it looks like they both do it at the same time.
Regardless of if the disks sleeping caused this ill turn that off since I dont need it.
Thx

I can't say if you should have run into this earlier. We just discovered this issue through a user recently, so it is a reasonable guess it may be affecting you.
Let us know if this helps, though.
If you had these disks for 20 months, then the other explanation is that one of the disks is failing. Does SoftRAID show SMART data for the drives? (especially: reallocated sectors 0 should be in the disk tile) That indicates that all SMART parameters are available.
Another option is to backup your volume and use the next weekend to certify both drives and see if they pass.

SoftRaid shows, Smart Status: Passed and Reallocated Sectors:0 on both drives in the raid. I already wiped the volume and Certified both old drives. They both Passed.
The drive that did have errors has been removed and the Raid rebuilt with a new Red Drive in its place.

All I can suggest now is watch for more errors. disk errors are serious events, they do not happen randomly and are indicative of a hardware problem.
