I recently installed 3 external disks as internal disks, removing the casing etc. I made one of these disks "Active" in the disk management program. It is not the boot drive. Anytime i access this drive explorer freezes and it forces a reboot and wouldnt find the operating system. I then ran the diskpart program from dos and marked the disk inactive but this led to complete failure. I have just reinstalled XP and the disk is still marked active and crashes the pc when accessed even though the computer boots fine. Ive ran the disk check on it and that makes it crash too. How do i make the disk inactive ? 1 person needs an answerI do too

hello Niall Harpur : follow these directions :1. Windows +R 2. Type "cmd" 3. At the prompt type "diskpart" 4. then after the ">" symbol type " list disk" DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ---------- ------- ------- --- --- Disk 0 Online 28 GB 1536 KB Disk 1 Online 233 GB 993 KB 5.Now select the disk which you want to make INACTIVE (For instance if i want to make my Disk 1 as active i.e where the OS is installed and REQUIRED to boot, i need to select the drive which i want to make INACTIVE. In my example DISK 0) DISKPART> SELECT DISK 0 Disk 0 is now the selected disk. 6. Type "list partition" DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Primary 28 GB 1024 KB 7. Since there is a single partition on DISK 0, select it by issuing the command "select partition 1" DISKPART> select partition 1 Partition 1 is now the selected partition. 8.Type "inactive" - this will make disk 0 partition 1 as inactive ============================= Explanation : This error crops up because you have been in Computer Management > Storage > Disk Management and selected more than 1 drive as ACTIVE together with the one which was already active- the one where your OS was . Point to remember : THERE SHOULD BE ONLY ONE ACTIVE DRIVE SO YOU CANT SET MORE THAN ONE DRIVE AS ACTIVE If this post helps to resolve your issue,Please click the Mark as Answer check mark on this page THANK YOU AND GOOD LUCK
