zaher Identical to an entry available since DOS 3.0. Unfortunately, this process doesn't seem to be reversible, as none of the Samsung tools (ESTool or HUTIL) nor HDat2 were able to switch it back on.

It supports only BIOS boot and only from MBR/msdos disk. In general, Windows forces type of partitioning depending on the firmware mode used, i.e. You'were 1000% correct.That was exactly what I did and as soon as I choose the 16-GB clip mode everything returned to normal.I'm a happy man with my 250GB hard disk drive My System Specs Computer type PC/Desktop System Manufacturer/Model Number Custom Build OS Windows 7 Ultimate x64 SP1 CPU AMD Phenom 2 1090T Motherboard Gigabyte GA-890FXA-UD5 Memory 2x8GB Kingston HyperX Fury Black http://www.sevenforums.com/hardware-devices/369847-how-return-drive-mbrs-fats-their-pre-windows-7-states.html

Some FAT32 implementations support a slight variation of Microsoft's specification by making the FS information sector optional by specifying a value of 0xFFFF[24] (or 0x0000) in the entry at offset 0x030. Thank-you. Deal with the OS issues after you sort BIOS.

type CLEAN type CREATE PARTITION PRIMARY type SELECT PARTITION 1 type ACTIVE type FORMAT fs=fat32 type assign The drive should now be formatted and marked as active and fat32. There is nothing else within the window (i.e., no drives to select). I tried everything, including zeroing out the entire drive (took 24 hrs0 and the damn DDO is still there. Do you have a paypal donate option?

If you are brave enough, you can also try the following: run the program, select your hard drive, and then when you see the "Restore Capacity" button, re-power your hard drive However if Arch is installed in BIOS-GPT in one disk and Windows is installed in BIOS-MBR mode in another disk, then the BIOS bootloader used by Arch CAN boot the Windows Haaaaa Feels better to get that off my chest. 3 Cheers for the HDDGURU.

A bit of a work though if you have screws and whatnot. March 13, 2014 at 6:00 pm gwapito I need to try this. Some operating systems don't support other sector sizes. The Windows NT family and some alternative DOS versions such as PTS-DOS fully support 64 KB clusters.

Now the 120Gb drive that only reported 31Gb is as it should be. I had a problem loading win xp that is related to the DDO. Windows Vista does not have any issue with big drives. Especially getting windows delayed write errors the higher up the drive as you fill it. (back to my first paragraph).

When I did not delete all partitions I was asked every time after the install, during start up by the windows boot manager to select ether win 8 or win 7. http://gbcmedina.com/how-to/reinstalling-windows-7-after-hard-drive-wipe-product-key-incorrect.php Since such volumes were found to be created by Windows operating systems under some odd conditions,[nb 8] operating systems should be prepared to cope with these hybrid forms. I decided to restart my PC and then the terrible thing happen. Thanks Squatty and all the guys from Cool Hand Luke

BUT, after powering down and powering up I enter the BIOS of my motherboard and ,to my surprise, I found my HD capacity short of 243 megs !!!!!! See Volume Boot Record. It is a snake biting in her tail.

So the MicrosoftBoot folder will be copied into the previous Boot folder like so: E:EFIBootBoot (two Boot folders don't seem right) or did you mean copy the file contents from the A zero entry indicates that this entry is reserved, but not used. The implementation of a single-sided 315 KB FAT12 format used in MS-DOS for the Apricot PC and F1e[36] had a different boot sector layout, to accommodate that computer's non-IBM compatible BIOS.

I have a WD1001FALS 1TB and suddenly VISTA and BIOS recognize only 33MB.

However, after trying this on 4 different machines,(3 desktops and a laptop) it only seems to recognize EIDE drives, not the SATA that I want to repair. Unused for drives, which don't support CHS access any more. Determine LSN=SSA+(CN−2)×SC, where the sectors per cluster SC are stored at offset 0x00D. This location overlaps with EBPB formats since DOS 4.0 / OS/2 1.2 or the x86 compatible boot sector code of IBM PC compatible boot sectors and will lead to a crash

Do not format the drive as NTFS or you will only be able to boot into the installer in BIOS mode. I would remove all drives, clear CMOS and add the drives 1 by 1 to the appropriate SATA ports in order.
