have three dvd writer and Plextor Premium cd writer installed. so 4 drive letters is reserved for these devices. How many hard drive partitions can I have ? O/S Wn XP Pro SP3. My computer is showing 20 partitions (drive letters) for 9 hard drive installed. How many drive letters/partitions do I have remaining that Windows will recognized?

Drive letters/partitions are two different things, please tell us what you are trying to do.

9 hard drives with 20 partitions (20 drive letters assign by Windows). 2 dvd writer and 1 cd writer, and 1 floppy drive took 4 drive letters. My question should be how many drive letters do Win XP assigned. By my calculation, only drive letter B and Z is open. I understand that letter B is not use. So when I attached an external hard drive to transfer files, Win only recognize the external hard drive as one partition and assigned drive letter Z to it even though the hard drive in the external enclosure have 3 partions. Have I bump up against drive letter limits or is there a work around?

Yes, you bumped against a drive letter limit.

Workaround:
In disc management, you can mount a volume (drive or partition) into a NTFS folder instead of assigning a drive letter.
I am doing this with a second internal HDD. Instead of using drive letters like D:, E: F:, I access the partitions via a folder C:\mnt like this:
D: -> C:\mnt\HD2_part1
E: -> C:\mnt\HD2_part2
F: -> C:\mnt\HD2_part3

Saves a lot of drive letters :slight_smile:

thanks Michael for your confirmation on drive letters. can you elaborate on how you do the work around? Also, once this is done, can the drive/partition be utilitzed the same way as normal( eg. disk defragmen, disk chsk,etc.)?
Thanks:)

Also consult Windows Help (Disc Management is the keyword)

Defragmentation works with a slight inconvenience: You need to run Defrag from the Start Menu.
CHKDSK supports volumes mounted in a NTFS folder, you need to run it from the command line.
