Im looking to buy a single heavy use storage drive in my desktop and i’m considering the Red over Green due to improved performance and lower noise thanks to 1TB platters. However since the Red drives have TLER enabled and that is not ideal for a single storage drive i was wondering if the feature can be disabled using western digitals tools. Also would disabling the feature keep it off even after power cycling?
BTW are there any other disadvantages by using a red drive over a green for desktop storage? Price is not a factor in this case.
I have the same question but for a small NAS. It is not based on Linux like QNAP / Synology / etc… but on ZFS (FreeBSD / OpenIndiana). As Linux benefits from TLER but ZFS does not need (in fact does not like) TLER, it would be great to disable TLER for the Red series via a renewed WDTLER utility.
So if annyone from WD could be able to comment on this?
As far as I know it cannot be disabled, unless you modify the firmware in some way. But you can also call tech support to see if the offer any utilities for that.
AFAICT, TLER (Time Limited Error Recovery) is essentially identical to the Error Recovery Control (ERC) feature set defined by the ATA standard. I believe the ERC setting is volatile, ie it does not survive a power cycle. However, one possible workaround would be to automatically configure the ERC settings at very boot using a utility such as smartcl.
