Hello Barbgraj Yes, what you described should work. Here are the key points on picking a SCSI drive: I'm pretty sure that we no longer sell SCSI drives. I know that we do not sell them new, but you can try our spare parts department to see if we have refurbished drives for sale(800 357-3355 or 800 901-3355 ext 7269938). Thanks
 Our Poweredge 2600 has finally experienced a drive failure, and of course I have no spare drive in hand. ( We had hoped to decommission this server prior to a failure, but the server has decided not to cooperate! :emotion-1: ) anyway, the drive is a Seagate Cheetah Ultra U320 SCSI drive. I need to know what criteria are the critical ones for replacing this, since they're not making the ST373453LC anymore. As long as it's 80pin, Ultra U320 SCSI, and as big or bigger, should it work????  If I stick with the Seagate Cheetah line, should I be okay? Can't find any kind of replacements on the Dell store site, did I miss something?  thanks. 
replacing a failed SCSI drive in RAID array?
