Drive letter disappear after reboot

If you've got no other volume that size and everything else you say is true, it does look as though you've selected correctly. Do you know why it's flagged as hidden? Internal or external (I see a SiI 3132)?

Not a clue as to why its hidden. This is an internal raid. I'm not sure if this is the one running off the board or an external card. I think its the one coming off of the external card.

I've been asked to update the drivers but I'm scare of doing so because the last time I did that, I lost the RAID which is why its on a new card (I think)

Do you think it is hidden because it's the mirror of your other drive?

I wouldn't think so but then again, I'm not computer technician. I feel confident though that the raid is that volume because (correct me if I'm wrong) under device manager > disk drives, the only thing listed is 3 drives: (1) stripe raid which is the OS drive, (1) maxtor sata drive which is the temporary download drive and lastly, SiImage SCSI Disk Device (to be exact) which is the card that is installed controlling the RAID I'm having problems with.

For it to be the mirror, wouldn't it have to show up as a disk and not a RAID?

So both Disk Management and Diskpart show only 3 physical drives, and you know for a fact there are 5 physical drives in the machine:

1 entry for a single drive
1 entry for a two disk stripe
1 entry for a two disk mirror

Sound right?

Use Diskpart to check the other RAID set to see if it also has that hidden attribute set...

That is correct!! I'm certain that there are a total of 5 drives in the computer: 2 for the stripe on the NVIDIA controller which is on board, 2 for the SiImage controller which was added and a single drive.

Attached is the screen shot of the detail on the stripe volume. I was comparing this detail with the mirrored volume and I noticed that the stripe is considered a RAID and the mirror is considered a SCSI Disk Device

Okay. You can try clearing that hidden attribute using Diskpart. Select the appropriate volume as you did before, then enter:

attributes volume clear hidden

Detail the volume again and observe the attribute truly cleared. Then see what you've got as far as drive letter sticking. If it doesn't work you can change it back to what it was by entering:

attributes volume set hidden

I cannot guarantee it won't mess with your RAID setup, but I don't think it will as you're only messing with how the OS is viewing the RAID volume as a single entity, and not the individual drives.

I was comparing this detail with the mirrored volume and I noticed that the stripe is considered a RAID and the mirror is considered a SCSI Disk Device

I've got a SiI card added to one of my machines and can confirm. Not a RAID setup and no internal drives, as it only adds e-SATA ports for external use. An HD dock is connected with two HD drives and they both have similar descriptions.

Let us know how it goes if you decide to give it a shot!

I'm going to wait until I back the data up. I need to free up $100 so I can buy another drive. Like I said earlier, it's not at the top of my list just yet. It will be though when it fails and I lose everything

Well, don't forget to post back! Looking forward to finding out how it goes!

Hello,

I'm facing a situation very similar to the one discribed in the first post of this thread.
Here is how i got there :

I bought a TV not long ago, and i wanted to try its record option, so i plugged my external HD in the usb port of the tv to store the recorded video. When i plugged it back to my computer, i had a message saying i couldn't use the HD unless i would format it. I found out that the HD went from NTFS to RAW, and i was able to change it back to NTFS without formating the it (i can't afford losing everything i have on this HD). I was rather happy, but the problem is only half solved.

Now i'm facing this situation :

Whenever i plug the HD in my computer, i can hear the "pop" sound, which means the drive is connected correctly. The drive won't show up in "my computer", but it shows up when i check the device manager. As for the creator of this thread, my drive has no letter assigned to it. I can manually assign one to it and by doing so, the drive will magically appear in my computer, and i can use it (all my data are still there). The problem is, whenever i unplug the drive and replug it back after, the letter previously assigned to the drive isn't there anymore, and i have to manually re assign it everytime.

On a side note, my HD (a WD) used to show up with a WD icon in my computer, but when i make it appear by assigning a letter to it, it doesn't have the WD icon, just the regular drive icon.

What i would like to do is to find a way to make things back the way they were before without losing any data (i read about the zero thing on page 3, but i don't want to lose my data so i can't use it).

If this sounds familiar to anyone, please, elighten me, i really need help.
Thanks.
