Impossible to create/format install Windows 7 on unpartitioned HD-Collection of common programming errors


  • slhck

    I am going nuts reinstalling Windows 7 on one of those Acer aspire all-in-one… The original OS (Windows Professional x64) was not starting, after the initial screen the BIOS was prompted. So

    • Step 1: I tried to access the system partition and reinstall everything but could not get to that point

    • Step 2: I set the BIOS to  native IDE and I tried to insert my original copy of Windows Professional and do a clean installation, but it does not allow me to format/create another partition for the installation mask

    • Step 3: I tried to install Ubuntu and I cleaned the whole hard drive, I was getting an error at some point during installation so I decided to get back to Windows

    • Step 4: Windows 7 again, at the disk screen of the Windows installation I opened the prompt and played around with DISKPART

      • I listed the disk and the HD was disk 0.
      • I selected disk 0.
      • I CLEANed disk 0 successfully.
      • I tried to create a CREATE PARTITION PRIMARY but gave an error about the cache being corrupt and the disk not being up-to-date (after I tried to create a partition in disk 0 it disappeared when I try LIST DISK and I have to restart before it can list DISK 0 again. RESCAN did not work).
      • Tried CLEAN ALL (2 hours) and succeeded.
      • Tried again to create a primary partition and failed, same errors
      • Tried to install my old copy of Windows XP Pro and it seems to work, it creates a partition, formats (only “quick” worked, slow mode was at 0% and after 1 hour so I stopped), it starts installing and at around 90% installation it says it could not copy a file and it stops.
      • Back on Windows 7 again, it says that the hard drive has 490+GB unpartitioned but won’t create a partition and format.
      • I tried again with DISKPART as I thought I messed up the MBR when I installed Ubuntu, so I did all of these instructions.

    The errors were:

    • On bootsect:

      the system partiton was not found, Data error cyclic redundancy check

    • on bootrec /FixMbr:

      A device attached to the system is not functioning

    But it did not work, and I still can not partiton/format/install on a blank HD. I tried some bootable clean disk tool and started an infinite loop on the same errors.

    The BIOS setting are: SATA: native IDE. If I set AHCL (or something like that) it does not load the HD and the DVD. Quick start/quiet start: disabled.

    Are there any other options or tools I can try before I change the HD (that is my last option)?

    Sir, the erro message (step 4-4) was clear as clean water. The disk cache (RAM inside the HDD) is corrupt. Either you find a way to completely disable it (and have a disks that is as slow as a tortoise), or you get a replacement disk.

    odds: -> encountering an error in linux: bail out -> encountering an error in windows: retry, retry, retry, ask a question. Weird behaviour…
