Dead disk on an 1850, can I mix drive models?

I did not even notice that it was SAS. I have a SCSI drive that should fit the bill so I will give it a try today.

thanks!
Dave

You can't replace a SCSI drive with a SAS drive.  You can use a different model of SCSI drive of the same  size or larger and same speed or faster.

Hello,

I have a poweredge 1850 with what appears to be a dead drive (see below). I have been told that the drive model: 146 GB Ultra320 SCSI Cheetah 10K.7 #: ST3146707LC Has been discontinued and that "146GB CHEETAH 15K.6-SAS 3.5 16MB ESG" is an alternative. Does anyone know if this will work properly or have any advice for me?

Thanks!
Dave
