I have had this experience now with 2 Seagate drives sent in for RMA repair. As you probably know when they receive the defective drive another refurbished unit is sent out (different serial number).
Both drives were 18GB SCA LVD's (ST118202LC). The replacements had model ST118202LC on the label and looked identical but when queried by the host adapter were SX118202LS. Also these refurbished units operated at 40MB/s and not 80MB/s which the original units did. I can tell since my host adapter card, Adaptec 4-channel 3400, reports this info.
I was interested whether others have noticed this practice. I have not called them on it yet as otherwise they have provided very good service and I have had good luck with their products.
If these drives failed soon after being purchased, you may be able to get the seller to replace them with new stock and to treat them as DOA's back to Seagate. Good to know for future reference.
Where did you buy the original drives? Seagate does not look at the model number when they exchange drives, but at the top-level assembly part number, which will be different for drives provided to various OEM's. If your drives originally had OEM firmware and your vendor changed the firmware to the standard/generic firmware, you'll get back the orig- inal firmware when you RMA the drive, since that information is part of the assembly number.
I've had drives that my local Seagate rep had upgraded to ASA-II code from the ASA-I code, and when I RMA'd them, the replacements came back with ASA-I code because that's what the label said.
I've RMA'd drives that were no longer made, and received newer (better) models in return.
Without knowing what the labels said on your original drives, I can't say if you ran into this particular issue. You should certainly call them and find out what they think happened. Note that with the serial numbers from the "in" column on the yellow sheet you got back with your drives, Seagate can determine who the original drives were sold to, and if they were OEM drives or not.
