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

[David Cornell]

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
