Can I add a 160Gb harddrive?
to a 7000US system and of course get the full 160Gb (beyond the 137Gb 37
bit limit)? I understand a system needs to have LBA Addressing support, but I cannot determine if mine has that or not. I've looked at all the diagnostic reporting tools I could find and went through all the BIOS settings and displays, but nothing. Also, if I can get the hardware to recognize it, will WinME handle it with FAT32? If not, what XP file system should I be looking at? |

I doubt a Jan 2001 release PC would have the necessary 48-bit LBA to allow
installation of a drive larger than 127GB, not 137GB, as you noted. You're probably limited to the 120GB drives.

Thanks HH. It also seems like Compaq is not offering a BIOS upgrade to
this system that does support LBA . 1. So what if I upgrade to XP - does that have native 48 bit LBA regardless of my BIOS or IDE controller? 2. It appears that Seagate offers this DDO (Dynamic Drive Overlay). From what I can best tell, it gets around the lack of LBA support in the BIOS, but I'm still confused about the Win ME OS in this case. Any ideas? 3. Would buying a ATA PCI controller card fix the problem for LBA support without any other changes?

hi ,
you should be able to partition and format the disk for win me with the utilities available from the manufacturer of your drive . the controller card will offer better performance than the ddo software . if you don't have an available pci slot the ddo software does work . I am running western digitals version on my system . i was able to partition and format my 120 gb drive with 98 using their utility . hope this helps, terry ============== Posted through www.HowToFixComputers.com/bb - free access to hardware troubleshooting newsgroups. |

For the long haul, you are 1000% better off with an ATA PCI controller card than
mucking around with DDO or similar software kludges. I've had a system here for service with WD's EZ-Drive (like DDO) installed. What a pain in the butt to do something so simple as reinstall Windows! Invest the $30 or so in the short term to save many dollars and headaches in the long term...

Tom thanks for your replies - they help.
According to Seagate, the DDO does not affect performance. Here's their statement on it. So my question back to you is why do you say it's slow? "... Note: It is a common misonception that the DDO is some kind of memory resident program or that it has the potential to slow disc access by being in memory. Like all BIOS routines, the DDo is discarded from memory after about 4 seconds into the launch of the operating system when the 32-bit direct access device drivers take over. The DDO exists only to detect and then present the full capacity of the disc drive to these operating system device drivers...."

Tom,
DDO (like Western Digital's EZ-Drive and similar software available with most hard drives and as a free download from the drive mfrs web site) does two things. First, it inserts itself into the old-timey DOS interrupt 13h software interrupt chain, replacing the motherboard's built-in BIOS. Next, it places info about the drive's characteristics down in low memory where a device driver can expect to see them. Windows, even Windows XP, boots up with at least a small non-protected mode stub that starts reading the operating system, finds a hard disk device driver, and switches as soon as possible to the protected mode device driver. From that point on, neither the hard disk BIOS or its surrogate DDO is ever heard from again. There is no performance hit. But, and it's a BIG BUT, data recovery and/or operating system reinstalls can become very much complicated by the use of DDO or similar software. Hence, my never-ending recommendation to use a hard drive controller card instead of DDO or its counterparts. Note that the design of Linux has far less reliance on the hard disk BIOS to provide info about drive geometry, because Linux is smart enough to read this information from the disk drive directly almost as soon as it gets its operating system bootstrap record into memory. Just think what Micro$oft might learn about sound software engineering principles if they were far less arrogant and took the time to see how other alternatives work...

without a performance hit, but..... Perhaps it is just my imagination, but it sure seems our 7240 slowed with overlay...maybe I'll have a chance to roughly compare in the near future, when I retask the 7240 and put the smaller HDD back in without overlay... Dale |
