A {{Mono|WDTLER.EXE}} utility allows the enabling or disabling of the TLER parameter on Western Digital hard drives. This utility is written for [[DOS]]. The utility works on and makes changes to all compatible Western Digital hard disk drives connected to the computer. The change survives power-cycling. Western Digital used to mention the tool in an FAQ.<ref name=customer-service>{{cite web |title=TLER / CCTL / ERC thread |url=https://hardforum.com/threads/tler-cctl-erc-thread.1562128/ |website=[H]ard{{!}}Forum |date=16 November 2010}}</ref>

The utility comes with three batch files, {{Mono|TLERSCAN.BAT}} to get the current state of the TLER setting on all the hard drives, {{Mono|TLER-ON.BAT}} to enable TLER, and {{Mono|TLER-OFF.BAT}} to disable TLER. The included {{Mono|TLER-ON.BAT}} will set the Read & Write TLER time to seven seconds. It is possible to can use the {{Mono|WDTLER.EXE}} utility directly with the <code>-r# -w#</code> parameters for a custom timeout.

Western Digital claims that using the {{Mono|WDTLER.EXE}} utility on newer drives can damage the firmware and make the disk unusable. The utility is no longer available from Western Digital, and new drives will not be able to have the TLER setting changed. RE disks are only suitable for RAID arrays and Caviar are only suitable for non-RAID use. The utility still works for older drives{{which|date=May 2023}}<!-- what is the cutoff? -->.
