Corruption archiving .rar files to external drives
I'm having an issue that's baffling me and I'm hoping somebody can shed some light on this.
I'm in the process of archiving some of my larger files into .rar archives on some external hard drive enclosures using winrar. I rar the files directly from an internal HDD to an external drive via USB 3.0. I'm using a Renesas internal 3.0 add-on card with 4 USB 3.0 ports. The external enclosures are Icy Dock 4-bay enclosures.
Here's the issue - winrar completes the operation as if there's no problem, but when I test the archive immediately afterwards it fails and says corrupt volume. I test using both winrar and 7-zip. Both fail. I never used to have this issue until a few weeks ago when it first started happening. Even weirder - If I archive the files to my other internal drive first, and then copy those .rar files over to the external drive, they test okay. It only gets corrupted if I archive them directly to the external drive. This only started happening recently - I have always archived directly to the external enclosures previously with the same drives and same external enclosures without issue. This happens with both Icy Dock enclosures with several different hard drives.
I've tried swapping USB cables and even different USB 3 ports on my internal card. Sometimes I get corruption and sometimes I don't. I just tried 20 minutes ago and the winrar archive failed - then I tried zipping them directly with 7-zip and they didn't fail - then I tried again with winrar and this time it didn't fail. I have no idea what's going on. Any ideas would be appreciated since I don't know where to begin troubleshooting this.
