I whipped out a copy of HDAT2 and sure enough...the weasels at HP have set an HPA that divides the drive right in half! What's more, the Compaq BIOS Will Not Allow Any Diddling With The HPA. It not only locks that out, but also blocks any attempt to send the in-drive secure erase command. That was easy to work around--HDAT2 suggested booting the system with the drive unplugged from the data cable at first...after which I'd plug the cable in (how's that for trying?) and run HDAT2.

I'm curious to know. I know I've run up to 120GB drives on mine, and more than that once (320GB) Windows 2000 had taken over from the BIOS and removed the 48-bit LBA limit.

Hi!
My suspicion is that the Compaq SSF has a BIOS limit of 132GB, another in the long parade of hard-coded BIOS limitations this industry has seen, starting with 528MB on 386/486 systems. It seems inline with any other system of the time. A notable exception is my Dell Precision Workstation 220 "toy". The 2002 A13 BIOS on that machine has 48-bit LBA support...the BIOS can see and utilize all 200GB of the second installed hard disk. (Funny that my newer Latitude D800 doesn't have 48-bit LBA support in the BIOS...) I actually still have a couple of the Compaq P3 SSF systems here. I've come into probably seven now, and of those, at least two went out after being refurbished and provided with XP Home. They're plenty good enough for a "second computer" or something for kids to goof around on. I love the ones I have, although recently I've found the Evo D500, a Pentium 4 Deskpro with a black/silver case and only minor internal changes. AFAIK, Compaq is the only name-brand mfr that imposed on its hard drive vendors to limit the capacity of a drive at the factory. Interestingly, when I had my Contura 410C laptop, they kept sending it back with bigger and bigger drives each time it smoked one. (It had a tendency to blow up the Quantum Daytona 2.5" drives, so one day it came back with a Seagate Marathon 420MB drive. That one blew up too, so it came back with an IBM 720MB drive. The IBM drive survives today in a PS/2 L40SX laptop.) I guess they couldn't boss the 2.5" drive makers around in the same way, or maybe they treated the machine differently because it was in the hands of a "mere mortal" who didn't contract with them in any special way. I'm with you on Maxtors. Every so often, I gather out 5 or 6 and sell them quickly on eBay. I don't even want to give them to my enemies. Same here, although I have held on to a very few as they have worked properly. I don't know what miracle is keeping them alive, and I haven't checked too closely. Seagate Data Recovery Services (!!!) of Canada actually bought a Maxtor drive from me on eBay... I was curious, so I asked them why they wanted it. Amazingly enough, they needed it for parts to recover a drive someone had sent them. William |

You mean there is hope that I can get some reasonable dollars for the Maxtors that keep piling up here? If you don't mind my asking, how much did you get and for how much capacity? All the drive manufacturers offer data recovery services, either directly or indirectly by brand-naming OnTrack data recovery. This is a lucrative business, but it requires a clean room for some classes of recovery involving drives with internal contamination from head crashes and/or stuck heads. The few simple recoveries I have done involve swapping PCBs from drive to drive when a failed drive simply won't respond. But for the PCB swap to work, the firmware on the two PCBs has to be absolutely identical. That's why some models of drives have decent value to a drive recovery service. The 2.5" drives back in the day of the Contura did not yet have the rich ATAPI command set that includes being able to change the visible capacity. The more complete ATAPI command set seems to have matured in the timeframe of 6 to 10 GB 3.5" drives. Even so, there is still no consistency in the use of SMART arributes, which are supposedly a manatory part of the ATAPI standard. Happy Thanksgiving weekend or Black Friday, depending on how you celebrate it... Ben |

Hi!
And if you look at what they or anyone else charges for such services, you find that you grossly under priced the drive when you sold it. I can't think of any data recovery outfit that has their prices right on their web site. (This is probably because you'd fall over dead from shock if you knew right away how many arms and legs (possibly a few firstborn children in there as well) it was going to cost...although, perhaps more seriously, it's because every case is different.) I didn't want the drive--and Seagate Canada was very good to deal with. The only pain was in dealing with UPS, who weren't sure if they did or didn't need customs paperwork. Turned out they did, which put a delay on of a few days. They bought it immediately, paid immediately and I spent the money on something that I'm sure I liked more than a Maxtor drive! 8^) William |

I was *astounded*...here comes a big company looking to someone like "little ol' me" to get them something they need? The drive was 20GB. It sold for $16.05. They wanted it *overnighted* via UPS...
