This is getting stranger and stranger. Now I'm beginning to suspect the damned
DeskPro EN SFF Version 3.13 BIOS. First, I installed a 20GB Seagate in the system. Neither FDISK nor Windows 2000 install would recognize the drive as larger than 8GB (8064K), even tho the BIOS acknowledged it as 20GB, and the Seagate diagnostics did, too. Next, I installed a 15.3GB Maxtor in the system. Windows 2000 installed itself on a 15.3GB partition. I guess that my next step is to try the WD400BB drive in a system known to be able to handle 40GB drives. If it shows up as 40GB there, I'll have to conclude that Compaq crippled the hard drive capacity in the Version 3.13 BIOS. And if that's the case, it would be stupid, indeed... Ben Myers |

No, the 20GB Seagate did not work correctly. FDISK and Win 2000 install both
saw only 8064MB or so. I now think there is a bizarre BIOS limitation like I've never seen before. The 32GB barrier would be unfortunate but understandable, altho Intel and other more generic motherboards from the same era top out at the newer 132GB. No jumper issues with the 20GB. Checked and double checked this all too often. But a 15.3GB Maxtor DOES work perfectly, which says that the BIOS hard disk capacity limit is somewhere between 15.3 and 20, probably 16GB. But I'm only speculating, because Compaq never provided any printed info on the inherent disk BIOS limitations...

That would be a first. I've heard of 32GB on rare occasions, 8gb and 137gb
frequently, but never 16gb ben_myers_spam_me_not @ charter.net (Ben Myers) wrote in message ... No, the 20GB Seagate did not work correctly. FDISK and Win 2000 install both saw only 8064MB or so.

Yes, me, too. DEC Pentium II & Pentium Pro computers with a Phoenix BIOS had a
bizarre limitation of 15 heads, which required manual setup with a max hard drive capacity of 15/16 of 8.4GB, however much that is. And Micronics Pentium motherboards with Phoenix (again) BIOS had a 4.2GB limit. Otherwise, I'll be darned if I can explain why 15.3GB formats with full capacity and 20GB does not. The DeskPro EN Version 3.13 BIOS has two different "BIOS translation options": "extended LBA" and "bit shift". What in hell is bit-shift? With this BIOS, I'm more inclined to think there is an extra f in bit-shift. Either way, the Seagate 20GB drive does not format to its full 20GB capacity, even when using Seagate's Seatools to set up the 20GB partition. Oh. yeah. I blew away the MBR and partition table with every trial with the 20GB drive... Ben Myers On Fri, 5 Nov 2004 13:33:14 -0500, "Tom Scales" wrote: That would be a first.

Well, I finally took the WD400BB drive and put it in a Micron system with an
Intel branded D815 chipset and a 45GB IBM drive originally. The WD400BB drive showed up in the BIOS as having a 10GB capacity. So it's not the Compaq SFF BIOS, altho it, too, seems a bit crippled compared to similar vintage systems. It's the damned drive with firmware doctored up to make just 10GB usable. What a waste...

Ben,
Sounds like manufacturing at Compaq ran out of 10GB drives and had some extra 40GB ones laying around. Also sounds typical of Compaq, unfortunately, to cripple the drive firmware to make only 10GB usable. HH ben_myers_spam_me_not @ charter.net (Ben Myers) wrote in message ...

I have the same problem with a WD307AA 30gb, a Maxtor Fireball 30, and Samsung 20gb. I tried to clean these drives with WD Data Lifeguar Tools, and they died. They then reported a smaller size drive vi FDISK. I then tried the W982E Start UP Fdd, Format C: FDISK t partition to100%, and reformat. No good! They still report smalle drive sizes. The funny thing is, every time I tried to fix the HD’s they got smaller. I’m down to 16 MB’s, yes MB’s on the drives. I thin the WDDLGT’s may have been contaminated, or the Start Up FDD was. also used W2k’s 4 Start Up Fdds’, but no go either. I Zeroed out all did a Fdisk /MBR …noting changed. The drives are still small or have n partitions at all, and will not take any FDISK or FORMAT. I think th Firmware (?) may have been contaminated. I searched the web fo anything that will redo a HD to factory specs, but found nothing. called the MFG’s but got no where. I’m about ready to buy new HD’s An suggestions will be greatly appreciated!

Thi is what I thought would happen, because the WD DLGDIAG diagnostic did the sam thing by writing zeroes to all sectors on the drive, including the MBR an partition table. I'm going to pull the drive anyway, and replace it with a 20GB Seagat to sell to a client. Thank you for the suggestion, even though to no avail...

(I cannot remember, though how it showed up in the BIOS.) The drive had been dual-booting Windows and Linux. Later Linux hadn' been removed properly. I didn't know the history of the drive then, and used all the tricks you've been mentioning. I finally succeded using a small program called "Slate". It removes everything, and I mean *everything* on a hdd. (Warning! Be sure which drive you choose to delete.) Afterwards the drive showed up as it should. -- JP Loken Using M2 - Opera -- BillBerit |

Well, at least I don't feel like I'm alone, and I'm definitely not crazy. It's
very interesting that you had the same sort of experience with three different makes of drives. In my case, I am now convinced that either WD or Compaq deliberately cripped the WD400BB drive firmware to have only 10GB of capacity, because that was the hard drive capacity delivered with an original DeskPro EN SFF computer, which also appears to suffer from a serious limitation in IDE hard drive capacity supported by its BIOS. I'll also bet that the WD400BB was either a spare part replacement or a factory installed disk manufactured after WD stopped making the 10GB drives. Your posting prompted me to google a bit. I found this URL on the HPaq web site with downloadable firmware updates for Seagate, Maxtor, and WD drives: http://h18000.www1.hp.com/support/fi...scat/4_95.html I just downloaded the WD firmware file. Hey, it's worth a try... Ben Myers On Thu, 2 Dec 2004 18:26:15 +0000, BillBerit wrote: I have the same problem with a WD307AA 30gb, a Maxtor Fireball 30, and a Samsung 20gb.
