drive not seen in disk management
I saw this same question asked on another group about a month
ago...but there were no replies. Now I have the same situation. I wanted to backup some data... so I popped a spare drive (know good) in an XP machine I was working on. The drive (80 gig) is seen just fine by the bios and if I look in the control panel...there it is... no problems with it. But nope...disk management does not see it at all tried both IDE channels and all jumper configurations CS master and slave nothing |

I guess there must just be something odd about that particular drive as since I've posted...I tried another drive and it's recognized it normally First step would be, what is in Device Manager ? There should be a "trail of bread crumbs" left as a result of the new hardware wizard finding a drive that wasn't present previously. See if there is an entry in Device Manager for it. The file "setupapi.log" has some info from the work of the new hardware wizard. Examine the tail end of that file for recent changes. If there is some evidence it is present in Device Manager, your next step might be the port of "dd". http://www.chrysocome.net/dd dd --list The output from that command, shows both raw disk and partitions. As the info on that web page shows, \\?\Device\Harddisk0\Partition0 represents a whole, raw disk. Partition1 is the first partition on the disk, so references to Partition1 imply a partition is recognized. If a disk only had a Partition0 entry, it could be that the MBR is empty or badly corrupted. Using that port of dd, you could attempt to copy the MBR to a file. For example dd if=\\?\Device\Harddisk0\Partition0 of=mbr.bin bs=512 count=1 What that would do, is copy the first sector of Harddisk0 to the file mbr.bin and place it in the current working directory of your "DOS window". You can then examine the file with a hex editor. The last two bytes would contain "aa55", the signature that is meant to imply that some previous tool loaded a valid MBR in there. If the last two bytes aren't a signature like that, then somehow the MBR isn't valid (was never loaded in the first place, or has been erased at some point). If the four primary partition entries in that table were corrupt, maybe that would be why Disk Management is playing dumb. If you want to erase the MBR, giving Windows permission to start over again, this would be an example of how to do it. This wipes sector zero of Harddisk0. Of course, you have to use the info in "dd --list" including sizes and the like, to be sure you're pointing this command at the correct disk. dd if=/dev/zero of=\\?\Device\Harddisk0\Partition0 bs=512 count=1 And if you accidentally pointed the previous command at the wrong disk, and wiped out the MBR, the program "TestDisk" can recompute the 64 bytes worth of primary partition info, while the Windows Recovery Console "fixmbr" can put back the necessary 446 bytes of boot code.

drive not seen in disk management
Sorry to hear about your problem ... I have it, too ! New Win7 system. Took my 2 Seagate Barracuda drives from my old computer and attached one of them to my new computer via external USB. The first drive was instantly recognized. I shut down the computer. Attached the other drive in the same way. Booted up. Drive not found in Explorer. In Disk Management, it is seen as Dynamic, Offline, Invalid. So, I replaced both drives in the old computer. Booted up. Both drives were recognized as always before. Shut down the old computer. Removed drives and tried them again via external USB and the same problem occurred. The one drive is recognized. The other identical drive is not. PLEASE HELP ! This is "driving" me nuts !!!! ;-) Thank you. -Bill -- hxl7 ------------------------------------------------------------------------ hxl7's Profile: http://forums.techarena.in/members/164657.htm View this thread: http://forums.techarena.in/xp-hardware/1278902.htm http://forums.techarena.in |

There is nothing wrong with using Dynamic disks, as long as you understand how to handle them (which I don't). Being unable to access the data, while the disk is on another system, is just one of the tiny details of using them (i.e. understanding what needs to be fixed). Since I don't need the hassle, if I catch a disk being Dynamic, I back up whatever is on there and fix it. Using Basic disks, I can then be less concerned about what happens when the disk is moved. IT support staff probably use features like that extensively, because it can allow extremely large volumes to be built. In a non-home environment, there is probably more justification to be using it. The dynamic disk has metadata on it, that in theory should survive transplantation to another system. If you spanned two disks together, maybe the disks only "make sense" if both disks are moved at the same time. I don't like complexity enough, to be trying stuff like that. For example, if I used dynamic disks and spanned two hard drives, would my Linux LiveCD understand the data contents, and allow me to look at them ? My setup here, emphasizes portability over all else, and my Basic disks can be seen no matter what OS I'm currently using. Paul |

Paul, Thanks so much for your reply. I think you're absolutely correct. The other disk when connected to the USB port is Basic. I have no idea how the one was set to Dynamic. It is also indicated as Invalid. When I try to Reactivate, the error message says that can't happen on an Invalid disk pack. Well, at least I know now what the issue is. Thanks, again!
