I have a 250gb SATA harddisk.which is working as a slave drive on my computer (primary is a IDE harddisk) everything was fine until today morning when i switched on the system to find that , out of the 4 partitions on the 250gb harddisk , 3 were missing.
under diskmanagement it says,
and shows G: on the right hand side as a partition with 232.88gb
but under my computer it says, G: total space 19.5GB, available 17.4GB.
Also H: I: and J: are missing!
Any help will be appreciated.

Re: 3 partitions missing on a 250gb SATA hard disk
I think you just got corruption. possibly heat related. or rootkit. uhh dynamic isn't right i think its logical .. right click the drive letter lower section and convert is best bet. i also dabbed with ptedit32 from bootable cd ubcd4win.com to fix lost partitions in prior experience.. but it was 1 partition and i found lba and other settings on drive sticker.

you will need to set up master slave configuration you will have to change your first boot device every time you want to use the second operating system During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS the scroll down to advanced bios features press enter change your first boot device to hd-0,press escape then press f10 to save to cmos to restart
Master/Slave designation is determined by jumpers on IDE drives. Most drives have adequate markings on them to identify these jumper positions. If not marked clearly, you will need the manufacturer's data to determine that designation. If you are curious about a working system just power-up in set-up mode (usually by depressing (f1-or-f2) during boot-up sequence, your system-bios will display this information for you. Jumpers for a PC hard drive are next to the power connector. Mostly in between the power connector and the data cable connector. These are used for setting up Master/Slave settings and also to limit capacity of the HDD seen by PC BIOS on some older hard disks. Usually settings which are selected by jumper setting to various locations are printed on the hard disk information sticker. however you could partition one hard drive with both operating systems on it this would enable you to choose which operating system you want every time it boots up you could use partition magic 8 http://www.filehoo.com/download/Partition-Magic-8,0.aspxPartition Magic 8.0 description Partitioning your hard drive plays an essential role in maintaining your computer-preventing conflicts, protecting data, improving efficiency, and increasing performance.
there was wrong in the set up of jumper in your 80gb hdd. Look closely to the 80gb harddrive, in between the ide cable terminal and the power supply connector you will see 8pin terminals paired together and a jumper use to short the paired terminals. It is most likely that the jumper was configure to detect your hdd as master. If the ide cable you use for the 80gb hdd was also use for the
dvd/cdrom drive then it will conflict with it if both jumper setting
was set to master. See the description of jumper settings in the sticker of the hdd. Position the jumper to slave.
Reboot your system again and see if the 80gb finally appear in your system. When system boot upon detection of hdd, the primary master should be 250gb while your primary/secondary slave will be read your 80gb hard disk.
> Primary IDE Master: NONE
> Primary IDE Slave: SP0822N
Good. Your motherboard has detected ONE disk-drive.
Do you have just one connected disk-drive on your PRIMARY channel, or do you have two connected disk-drives (via the 2 connectors on the one ribbon-cable on the PRIMARY channel) ?
If you have two drives connected via one ribbon-cable, you MUST set the 'master/slave/cable-select' jumpers on BOTH disk-drives, to identify which of the two will be the 'master' and which will be the 'slave'.
Also, check that the 'second' disk-drive is getting electrical power.
> NTLDR MISSING
Like I said, you deleted 99% of the files, including the 'NTLDR' file.
Your computer is trying to "boot" from the 1% of the files that still exist on the disk-drive, but cannot find the now-deleted file.
Perfectly normal, given that you have formatted the disk.
You may need to address the way that the old HDD was used in the BIOS. Meaning that if you had regular IDE drive the setting that may be in the BIOS might need to bee disabled and that could be the cause to the new SATA IDE controller you have installed as a boot device. Also if you are trying to boot from you new SATA drive you will need to install some form of and operating system on it like windows or whatever you have been using. Sometimes it’s easier to create a disk image of the old drive and transfer it to you new SATA, using a disk image utility like Norton Ghost. Of course I am assuming that you are using a PC and not a MAC. -Aaron
you can take backup of D drive om other computer .
Conect your harddrive to that other computers CPU but make sure that your hardddisk is slave which has issue you can set slave your hdd with jumper read on harddisk.
then connect it to cpu with SATA or IDE .
Then winxp find that all partition then take backup.
AND IFyou haven't other computer you need winxp bootable disk.
Boot your computer with winxp disk then follow the procedurer then you see on screen
your old winxp for repair then when it ask for "r"
Thwen it repair your winxp then you can use easily.
Looks like the controller on the Hard disk has malfunctioned. I am afraid, that the Hard disk has to be sent to an expert nearby for Data Recovery. They would have tools which could be used for getting your data intact. But again it all depends on the level of damage to the Hard disk.You may get all / some of your data ot you may get none. Please consult your hardware vendor for this
When u bought a new hdd, it shud not have any partition on it. but in ur case, I assume u have formatted it to ntfs but no operating system is installed in it.
If u want to make the new hdd as slave and have another old hdd as primary, that have already an operating system installed in it, then the problem shud be hdd boot priority in bios. Enter ur bios and check for hdd boot priority and put the old hdd to the top most order, then restart. this shud fix the problem.
If u installed OS in ur new hdd (win xp), 1) ntldr or ntdetect.com is missing on root dir. (c:\). If u have another computer that works and have xp installed, just put this new hdd along with the current hdd and boot to windows. Copy ntldr and ntdetect.com to your new hdd. Or another way is just repair using windows xp boot cd. 2)the windows partition is not set 'active'. to set active, boot into winxp setup and press 'r'. this will lead to recovery console. type ur passwrod for admin (def=none). use diskpart command to set active. for easy way, put the new hdd to another computer. boot to windows. rightclick my computer, choose manage. on left pane select disk manager. rightclick on ur partition, then set active.
