From the Seagate documentation: "Only drives with an 'R' appended to the product number are designed and certified for use with a Run Length Limited (RLL 2,7) controller. Note: early ST238 RLL drives did not have the 'R' suffix." The letter 'N' appended means a SCSI drive, not 'L' (but the example was correct). Just as a side note, many of the SCSI interface drives use RLL encoding, but this is transparent to the SCSI interface. -- Dean Brunette {ucbvax,etc.}!hplabs!oliveb!olivej!dragon {ucbvax,etc.}!hplabs!oliveb!dragon-oatc!dean Olivetti Advanced Technology Center _____ _____ __|__ _____ 20300 Stevens Creek Blvd. | | _____| | | Cupertino, CA 95014 |_____| |_____| |__ |_____ 'Such a strange girl, I think I'm falling in love' --The Cure
