Hello. We recently purchased some additional MAXTOR XT-480E disk drives to install into our RT 6150/125 system. Unfortunately the RT diagnostics do not recognize the disk as a H310. The stand-alone format utility on the Installation MiniRoot finds the disk but can not read or write to it. After closer inspection of a working drive from IBM and a drive from MAXTOR we noticed the following differences. I was hoping that some individual out there could shed some light on why the MAXTOR drives do not work. From the label on the back of the drive: IBM MAXTOR TLA 1094298 3 1094508 2 HDA 1013115001 1014294 PCBA 101554 1 10185285 A On the circuit board on the bottom of the disk we found three ICs with different labels attached (locations are assuming that the power connector is in the lower left corener when looking down on the circuit board): Location Description IBM MAXTOR Upper left Large IC 1015191 1018388 corner 5E.06 5E.07 C-1988 C-1988 Lower Small IC 1015368 1018952 middle A.20 M01.1 C-1988 C-1988 Lower Small IC 1015366 1018950 middle A.20 M01.1 C-1988 C-1988 When the stand alone format runs the folowing error messages are produced: HD2: Disk I/O Error - CMD=READ Err=0x10<ID-NOT-FOUND> Status=0x51<ERROR,SEEK-DONE,DRIVE-READY> Cyl=0 Hd=0 Sect=2 Sct=1 After producing a few of these format ask the following: Formating drive hd2: verify (yes/no)? Answering yes results in format complaining about not being able to read the drive configuration record. It then asks if you want to create a configuration record. After answering all the questions asked about the configuration format complains about not being able to write to the disk and spews out error messages similar to the ones above. -- Dan Ehrlich <ehrlich@cs.psu.edu>/Voice: +1 814 863 1142/FAX: +1 814 865 3176

The Maxtor drive in question does not have the short Index pulse that is
required by the EESDI controller. The customer needs to contact Maxtor to
find out how to get the short Index Pulse feature installed on their drive.
(It may require an added jumper or an component and wire adds depending
upon the level of the drive electronics card.)
