SBC-4 describes a RECOVERY TIME LIMIT field in the Read-Write Error Recovery mode page used to define how the drive performs error recovery.<ref>{{cite web |title=INCITS 506-202x - Information technology - SCSI Block Commands - 4 (SBC-4) draft revision 22 |url=https://standards.incits.org/apps/group_public/download.php/124286/livelink |access-date=22 May 2023 |date=15 September 2020}}</ref> The sdparm program is available to change this setting.<ref>{{man|8|sdparm|Linux}}</ref>

==== Western Digital ====
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.<ref name=greg/> Western Digital used to mention the tool on 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}}<!-- what is the cutoff? -->.
==== Hitachi ====
Hitachi customer service stated in 2009 that there is a Feature Tool for changing ERC (referred to as CCTL).<ref name=customer-service/>
