Windows 7: Drive letter disappear after reboot

Have you tried using any of the Diskpart commands to check the drive out?

And why don't you have any backup for its data?

The only thing that caught my attention with diskpart is "Location path: Unavailable". The rest seems to be ok (disk online, healthy, ntfs, it even has the letter i manually assigned to it when i uplugged it shown).

And for the backup, well, it would require another 2to HD and i can't afford it at the moment.

Can you post a screenshot of Disk Management (with drive attached, window maximized, panes/columns adjusted to reveal max info), Diskpart screenshots showing both drive and volume details.

Here are the screenshots (all is in French language but i'm pretty sure it's clear enough).

Disk management (just after pluging the drive in, no letter assigned yet) :

On the volume detail, does "cache=oui" translate to "hidden=yes"? I can't relate it to anything else I see when I detail my volumes.

Caché means hidden yes. Now that you mention it, it's a bit strange that it's set as hidden. Is this normal ?

I cannot guarantee there'll be no data loss, and it's always best to have proper backups of data, but you could try what I outlined here: Drive letter disappear after reboot

I doubt you'll experience a problem toggling that setting, I've done it and haven't experienced loss.

I was kind of affraid to try what you said because the words "data loss" didn't ring nicely in my head, but still i tried it, and it worked. Wonderful ! I'm really grateful, thank you very much.

You're welcome. I'm glad it worked for you!

I will say though, that you really should have backups of that data! Backup, backup, backup and more backup!

But I've got a question. I was wondering if it solved this issue too:

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.

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!
SOLVED

F5ing, thanks for your help. What finally broke the camel's back was Windows Back Up. I thought of this today and decided it was time to pull the trigger on your last suggestion (quoted in this post).

I went to run Windows Back Up and I didn't have the option to back up the drive that I had to assign a drive letter too every time I booted. I finally backed up my data and ran the commands listed above and it worked like a charm. A different drive letter stuck but after a restart and reassigning the drive letter and one final reboot, the letter stuck AND the drive shows up in Windows back up because its not *HIDDEN*.
