Titolo: Cambiare lettera al mio HD

Salve a tutti
Sono riuscito finalmente grazie ai vostri consigli a passare l' hd
secondario come disco di avvio, ed a trasferire tutto il contenuto dell' hd
vecchio sul nuovo...
Ora avevo una domanda... Anche se ho eliminato materialmente il vecchio C:,
il nuovo HD viene sempre riconosciuto come D:... Esiste un modo per cambiare
la lettera al drive?
Col Disk Management di WinXP non me lo fa cambiare, ovviamente, anche se il
disco e' piazzato come master del primo canale della mobo...
Esiste un modo?

Start > Impostazioni > Pannello di Controllo > Strumenti di
Amministrazione > Gestione Computer >
qui selezionio "Archiviazione", quindi "gestione disco", selezioni il
disco in questione, tasto destro e quindi "Cambia lettera e percorso
di unità"...

 di unità"...
E' esattamente quello che ho fatto, dice che per il disco di avvio non e'
possibile cambiare lettera... Dipende forse da qualcos altro?

In effetti hai ragione... credo che la cosa dipenda dal fatto che non
può cambiare lettera al disco che contiene il SO attivo. Comunque
credo che la cosa sia possibile ad esempio con i dischetti di boot di
partition magic, i quali avviano il programma in modalità dos.
Potrebbe essere rischioso però... io non l'ho mai fatto.

E' rischioso, comunque c'è un articolo della MSKB che spiega come farlo, con
tutte le controindicazioni del caso:

How to Change the System/Boot Drive Letter in Windows 2000
-----------------------------------------------------------------
The information in this article applies to:
  a.. Microsoft Windows 2000 Advanced Server
  b.. Microsoft Windows 2000 Professional
  c.. Microsoft Windows 2000 Server
  d.. Microsoft Windows 2000 Datacenter Server

IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key"
Help topic in Regedt32.exe.
SUMMARY
This article describes how to change the system or boot drive letter in
Windows 2000. For the most part, this is not recommended, especially if the
drive letter is the same as when Windows 2000 was installed. The only time
that you may want to do this is when the drive letters get changed without
any user intervention. This may happen when you break a mirror volume or
there is a drive configuration change. This should be a rare occurrence and
you should change the drive letters back to match the initial installation.
MORE INFORMATION
NOTE: Please be aware of the following issue related to drive letters:

WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys and
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
If you are running Windows NT or Windows 2000, you should also update your
Emergency Repair Disk (ERD).
To change or swap drive letters on volumes that cannot otherwise be changed
using the Disk Management snap-in, use the following steps.
NOTE: In these steps, drive D refers to the (wrong) drive letter assigned to
a volume, and drive C refers to the (new) drive letter you want to change
to, or to assign to the volume.
This procedure swaps drive letters for drives C and D. If you do not need to
swap drive letters, simply name the \DosDevice\letter: value to any new
drive letter not in use.
  1.. Make a full system backup of the computer and system state.
  2.. Log on as an Administrator.
  3.. Start Regedt32.exe.
  4.. Go to the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices key.
  5.. Click MountedDevices. On the Security menu, click Permissions. Check
to make sure Administrators have full control. Change this back when you are
finished with these steps.
  6.. Quit Regedt32 and start Regedit.exe Go to the
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices key.
  7.. Find the drive letter you want to change to (new). Look for
"\DosDevices\C:".
  8.. Right-click \DosDevices\C:, and then click Rename.
  NOTE: You must use Regedit instead of Regedt32 to rename this registry
key.
  9.. Rename it to an unused drive letter "\DosDevices\Z:". (This will free
up drive letter C: to be used later.)
  10.. Find the drive letter you want changed. Look for "\DosDevices\D:".
  11.. Right-click \DosDevices\D:, and then click Rename.
  12.. Rename it to the appropriate (new) drive letter "\DosDevices\C:".
  13.. Click the value for \DosDevices\Z:, click Rename, and name it back to
"\DosDevices\D:".
  14.. Quit Regedit and start Regedt32.
  15.. Change the permissions back to the previous setting for
Administrators (this should probably be Read Only).
  16.. Restart the computer.
