Look at the Warranty Status page here: http://extranet2.maxtor.com/servlet/WebAda...tus::WebRequest
scroll through the model numbers (remember that the DMax+9 models start 6Y...).
You will see multiple model numbers listed for each size:
40GB -> 6Y040L0, 6Y40P0
60GB -> 6Y060L0, 6Y060L04, 6Y060M0, 6Y060P0
80GB -> 6Y080L0, 6Y080L04, 6Y080L2, 6Y080L3, 6Y080M0, 6Y080P0
120GB -> 6Y120L0, 6Y120L3, 6Y120L4, 6Y120M0, 6Y120P0
160GB -> 6Y160L0, 6Y160L4, 6Y160L6, 6Y160M0, 6Y160P0
180GB -> 6Y180L0, 6Y180M0, 6Y180P0
200GB -> 6Y200L0, 6Y200L5, 6Y200L6, 6Y200M0, 6Y200P0
250GB -> 6Y250L0, 6Y250L6, 6Y250M0, 6Y250P0
Now the P0 models are the 8MB cache ones and the P0 models are the SATA ones, but look at the Lx models...
L0 = you could have either of the specifications for that drive size; they're not telling (except maybe the serial number gives it away). Perhaps they are going to label them properly soon, actually giving the head count in the model name.
What it does confirm, for any who still doubt it, is the use of different platter densities:
80GB with 3 heads/2 platters (60GB each) or 2 heads/1 platter (80GB)
120GB with 4 heads/2 platters (60GB ) or 3 heads/2 platter (80GB)
160GB with 6 heads/3 platters (60GB) or 4 heads/2 platters (80GB)
180GB ... not specified
200GB with 6 heads/3 platters (66GB) or 5 heads/3 platters (80 GB)
250GB got to be 6 heads/3 platters (80GB)
I'm not sure about the L04 models in 60GB and 80GB... surely these aren't using 40GB platters?
Generally it's very disappointing, isn't it ?
At least they might come clean about this issue now.
