    The system starts, and I can get into the BIOS, but it won't read the hard drive. I believe that the battery died, and the BIOS forgot what drive it had. I need the specs to enter into the BIOS. Acer tech support only will tell me that it is an Hitachi 7200rpm 250GB drive. What I need is the # of cylinders, the # of heads & platters, if I remember correctly {its been a long time since I've dealt with this stuff} I think I can get that if I get the model number. The site you provided was nice, but didn't give the model #. Thanks for your help.

Is the computer booting up at all, in any form, any displays at all??
A dead hard drive will not cause a dead bios or dead battery or if it did, it would be strangest dead hard drive I ever saw and I have seen a couple of strange ones.
According to the Acer website, I would need your serial # to find out specific information about your system, so I will just give you the website and you can stick the serial number into the box and see for for yourself what you have. This link may not work because it is a https ( secured ) website and I don't know if our system works with those, either way I will give the URL also.

    First of all, I answered your question in the format that it was asked in, I do not deserve a TFT as that decreases my overall percentage of success help here on Fixya. If you are having problems with Acer, I suggest you call again and let them know in NO uncertain terms that you want the hard drive model # of the computer in question and anything less then a complete apology for this lack of informatin would not be acceptable to you. Get one of their supervisors on the line. Now Hatachi makes multiple hard drives with similar specs, so without that info, using the technique that you want to use would somewhat dangerous to your system. But also realize one other thing, I would hazard a real good guess that any modern bios chip will not allow you to set up the hard drive in exactly the fashion you seem to wish it to. I.E. Your ability to manually control sectors, cylinders, and such on a relatively new bios would be extremely limited with that function completely taken over by the Bios identification routines pretty much totally over 6 years ago.
    If as you say the Bios battery has died and you have replaced, then there should be little to no reason why the bios does not identify the hard drive properly and without mistake. There could be three major reasons why the hard drive is not being identified by the bios with its new battery installed. One reason is certain kinds of low level software ( Ontrack for example ) installed onto the hard drive before installation of the Operating system and that probably would have occurred at the factory. This kind of software can and did in the old days mess up the low level communications between the hard drive and the Bios.
    Second reason, the hard drive is dead
    Third reason, Sector 0 of the hard drive is no longer capable of being read by the Bios.
    But my first and primary suggestion is to get back on the line with Acer and let them know in no uncertain terms that you want the model # of that hard drive. They have NO excuse for not giving it to you once you identify yourself with a serial # of the computer in question. The ONLY excuse they would have for not giving you that Hard drive model # is if they suspect that the computer is stolen and that the theft has been reported to them either by the original owner or some legal entity.
    I hope I have made myself clear.

    Thank you

    One other option would be for you to give me the serial # of the computer in question. I will see what I can find out and I bet I will find out more then you have.

    Exact model # of the computer would be extremely helpful also.

    One other reason for the Bios not properly identifying the hard drive. A possible firmware update to bios from ACER might alleviate the apparent misidentification of the hard drive, however that would not explain why the hard drive had been previously properly identified and working using the older firmware and it would not help in any case if the HD is dead.

    Ravel Lively Aug 25, 2008

    The Hatachi website that has the software you need to properly identify the hard drive is located here
    You will not need an operating system to run these troubleshooting tools, as they are mostly self-bootable using either a floppy disk drive or a CDrom drive. I hope you have one of those working on the computer in question.

    I have also sent an email request to Acer support asking for the details concerning all models of Hatachi drives that were placed in the Acer Power 1000 by them. They asked for the serial # of the original computer but it was not absolutely necessary for them to have it, i.e. that question was bypassed by the Acer support system. Now I have to wait for a reply, could be a while as they made it clear that the serial # of the computer in question would greatly speed up their search.

    If you haven't already tried it, open up your case and try resetting the BIOS jumper that should be located near the Bios chip. In most cases they were 3 pin connectors with a jumper located on pins 2 and 3. Resetting the jumper involved placing the little black or red or even green jumper over pins 1 and 2 for about 10 seconds ( with power off of course ), then placing the jumper back into its original configuration before powering the computer back up. It might be hard to identify the exact jumper that controls the bios chip, but take your time and use a magnifying glass like I do with a bright light of course.. This small step alone might fix your entire situation.
    Sorry for all the replies but unlike quantum particles, our human minds cannot be in all places in single instance of time.
    Take care, and I will get you anymore information you might need when you ask for it.

    It would seem that without your machines serial # I can go no further because if I tried to push this from this end, they would surely ask for the serial #. I would be more then happy to push this if you wanted, but I would need the serial # of the computer in question.
    However I also know that the Hatachi site that I sent you to earlier has to the tools to identify your hard drive in every conceivable manner.

At boot up press F2 to enter the BIOS. That is where the change has to be registered for your PC to recognize the new HDD. So when you get the first meny there you will find the HDD. If not, then auto detect the HDD. Within a second or two your new HDD will be recognized. Also from the back of the new HDD. ie, the Seagate, check if the Seagate is the master. If not, then you will find a diagram there which tells you how to change the jumper so that your HDD will behave as master. And I hope you are not using the other HDD as well?

Hard disk drive not detected

firstly check your cable connections, then log onto your bios setup menu during startup and check whether the Hard drive is detected by your bios, if it is then you can try to format the harddrive using the ntfs system (use the long formatt) if you are using windows xp or later if using any earlier os then formatt with the FAT32 system.
If your HDD is not detected by the bios then try to download bios updates for your motherboard and install thed in windows. is this does not work then its time to get a new HDD. thanks

Flashing Toshiba satellite 1800-S204


You query did not give any clues abt the PC/Motherboard and its BIOS revision.

That said if the PC/BIOS will not "see" the HDD then its is unlikely a cause of a virus.

Some old motherboards can't recognise a HDD if its size is more than 137GB. Some older motherboard also require than you set the HDD jumper correctly (Master or Slave).

At this stage, i am assuming the HDD in question is PATA or IDE (Old Spec). If the HDD is SATA (New Spec), then you will need a SATA port to connect the HDD. Ensure not to use both "old" molex power connector and "newer" SATA power connector together.

If the HDD is SATAII but the SATA spec for your motherboard is SATAI (initial spec), some motherboards and SATAII drives require that you jumper the HDD to allow it to work at the lower SATA speed.

If none of the above points apply try upgrading your system BIOS of the latest version. Also review the mortarboard's manual for more info.
