Sans Digital TowerRAID TR5M+B - 5 Bay eSATA RAID 0/1/10/5/JBOD Performance Tower with 6G PCIe Card (Black) Review

I wanted to share an important fix for eSata enclosure users!

Both my San Digital TR5M-B and TR5M-PB 5-bay eSata enclosures would randomly DROP out of Windows when I was moving a lot of files around. (or if I had 3rd party SMART monitoring and doing nothing) The only way to get them back was to reboot the server. (power cycling the enclosure didn't fix it) Well it turns out there is a simple fix all along. I wish I would have researched this more 12 months ago! The below fix applies to the 4, 5, 8, etc bay enclosures

The fix:
[...]

Problem / question: Anytime there is extremely heavy I/O all the disks drop out and the controller cannot see them anymore. Restarting the TowerRAID system and unplugging the cables does not help, only a reboot of the server. This is getting frustrating as when all the drives were connected to a 3ware 9550sx-12 they never had an issue. Is there another HBA I can try to solve this issue? I do not want to use raid, just single disk pass through.

SOLVED
Turn off "Link State Power Management" under PCI Express in the power options menu. (in control panel)
