I was advised (by Reno) to check registry for the following ENTRIES :



check the following registry key "HKCR\software\microsoft\windows\currentversion\policies\explorer"
make sure the value of NoDrives and NoViewOnDrive is 0.

On checking , I find that the value of NoDrive is "0000 02 FE FF 03 by"

and there is no entry as "NoViewOnDrive"

Thnks

Wait a sec, what's the question?sorry for the typo, it should be HKCU, not HKCR
HKEY_CURRENT_USER\software\microsoft\windows\currentversion\policies\explorer\nodrives

the key type should be REG_DWORD:
consisting of 4byte, each byte from the right hide a specific drive depending on which bit is on:

byte 1: drive A-H (bit 1 to bit 8 )
byte 2: drive I-P (bit 9 to bit 16)
and so on for byte 3 and byte 4.

can you access the drive by typing the drive name in windows explorer? example d:\First - I have been thanking all concerned. But I find "Thanked" as 0

Second - For Reno - Registry entry details are as under :

0000 02 FE FF 03 by (or something close to it- that b looks
like 1 and o with two dots on top)

Third - For Carbon Dudeoxide

The problem is I have (apart from floppy and CD drive) a Harddisk (partioned in to three i.e. C:, E: and F:) , an external HDD (partitoned in to three G: H: I:) and a digital storage with a memory card slot (presently no card) ( The Drive LETTER assigned to Memory card is J: and the other storage device is K:).

I am unable to see the letters J: and K: in my windows explorer.

This was the question.

Fourth : To All (specially Reno) : To the question whether I can access the drives through explorer - I checked and YES. I CAN.

I can access by typing the drive letter in the windows explorer address bar.

Also I can access the drive thorugh Ctrl panel->Adm tools->Computer managerment->Diskmanagement.

I think I will access the said disks through Wexplorer. Thank you once again (Though not urgent, any solution to the problem is welcome.).

if the value is "0000 02 FE FF 03 ïy", then my guess is the key type is REG_SZ. (i dont know why this key exist)
the valid key type for NO_DRIVES is REG_DWORD eg. 0x02FEFF03 (265859)
and default value is 0 (show all drives)

decrypting the value from right to left:
key value=0x02FEFF03
result : show drive C until H, show drive Q, show drive Y, and hide the rest.

if you can access the drive through windows explorer and cmd prompt, then the reg value is non-zero.
to make sure it is 0 with the correct data type, type this line in command prompt:
before doing this, backup your registry first
Code: [Select]echo y|reg add "HKCU\software\microsoft\windows\currentversion\policies\explorer" /v NoDrives /t REG_DWORD /d 0
the result of the command should be like this:
Value NoDrives exists, overwrite(Y/N)?
The OPERATION completed successfully

restart the computer for the effect to take change. then check again to make sure the value stay zero, if it doesn't ......... (that's another story)Holey Carp...
