They moved them all to desktop machines where they're getting reasonable life from them - albiet at a pricepoint that didn't make sense compared to the Seagates and WDs of smaller capacity. Often this kind of thing is part and parcel of one given model though, which means that unless you're talking the same line/model/whatever, it may not apply, and some of the issues are firmware related - so a production change can make a formerly unacceptable unit "ok" somewhere - or the reverse. This really bites - while I used to have issues with disks now and then when I ran my ISP, it was typically a rare bad lot once in a while. Products with this kind of failure rate just never made it out - now it seems that the manufacturers will throw whatever they can into the market, hoping they survive until the warranty runs out, and there's a trend towards shortening warranties to one year as well! I wonder if someone could go after these guys on their "MTBF" claims which all appear to be WILDLY optimistic..... Ah well, if I can't get the Maxtors to work reasonably well I guess I can try the Deskstar 250s... Thanks for the datapoints guys...
