Effectively, TLER and similar features limit the performance of on-drive error handling, to allow RAID controllers to handle the error if problematic. In a non-RAID environment, such features are unhelpful, and manufacturers do not recommend their use.

TLER can be enabled or disabled on certain Western Digital drives, using the tool WDTLER on a DOS bootdisk. Western Digital states that this feature cannot be disabled. <ref>[http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1478 WD Customer Help FAQ 1478]</ref> However users and independent editors have have reported that this feature can be disabled. <ref>[http://techreport.com/reviews/2006q3/wd-500s/index.x?pg=1 TechReport.com] </ref><ref>[http://www.silentpcreview.com/forums/viewtopic.php?t=38385&sid=16f0f601b1174a4ebf3fd6fd295b2351 SilentPCReview.com] </ref><ref>[http://www.fatwallet.com/forums/messageview.php?catid=18&threadid=660910&start=0 FatWallet.com] </ref><ref>[http://www.anandtech.com/storage/showdoc.aspx?i=2922 AnandTech.com]</ref> The tool allows this feature to be disabled by setting the values for read and write to 0 seconds.

By default, Western Digital [http://www.westerndigital.com/en/products/index.asp?Cat=2&Language=en Enterprise Drives] such as Raptor, Caviar RE2 and RE2-GP (RAID Edition) come with TLER Read "Disabled" (0 seconds) and TLER Write "Enabled" (7 seconds) while [http://www.westerndigital.com/en/products/index.asp?Cat=3&Language=en Desktop Drives] such as Caviar SE, SE16, and GP come with TLER Read and Write Disabled (0 seconds).
