re formatted drive cannot be seen

gjb
My system has 2 physical hdd C: and I: both NTFS XP Pro (SP3)
I re-formatted drive I: ( format i:) but now although C: works ok drive I: cannot be seen by the system.
Its a long time since I formatted a hdd and I probably forgot to enter a partion but if the drive cannot now be seen whats the best way of proceeding - thanks Gee

    It may just be that the drive hasn't been allocated a drive letter.

    Right click "My Computer", select "Manage"

    In the management windows, you should see "Disk Management" on the left, click that, and on the right will be your drives.
    If you have only 2 drives, then your "I" drive should be there as "Disk 1"

    Right click the drive, select "Change Drive letter...", and you should be able to add "I" to it.

    Thnaks for your speedy reply.
    The reformatted drive alreday shows correctly as I: but the problem seems to be that the two drives are contiguous because when viewed as you suggested they both have the same makers name but the size shown is the two drives added together but only one name i.e Maxtor is showing.

    If its a sata check to see if you have them pluged into your motherboard in the correct spots. Some motherboards have 2 spots for sata connections, one for RAID and one for single drive operation.

    I only re-formatted drive I: (India) and never physically moved it so I dont think your comment applies to my problem - but thanks anyway.

    On the command line I typed <Format I:> and the drive was then re-formatted.
    The primary Master drive is a Maxtor shown correctly in the BIOS as C: the primary slave is blank and the secondary master is shown as the CD Drive.
    Although both drives can be seen, one as C: and one as I: the system appears to be seeing one contiguous drive.
    Drive C: has a partition but drive I: does not have one.
    The BIOS setup only shows C: and searching for another hard drive does not find one.

    Both drives show in Drive Management but when you look at them they show as 1 Drive in My Computer with a total of the space of both drives added together. Is that correct?

    If it is you have created a RAID Array where the drives are striped so they show as 1 drive but with the capacity of both added together so I have to ask exactly how did you format the second drive and what switches did you use?

    In Drive management the two drives appear side by side as C: and I: but the total of C: is the two drives added together so your presumption that they may be striped could be correct.
    The I: drive was formatted from the command line with Format I:
    Drive C: has a partition but drive I: does not. I could add a partition to I: but am reluctatnt to do so until I get some advice.

    I would be reluctant to suggest doing anything at all without a solid working Backup in place.

    If you have a working up to date Backup you can try and the worst that can happen is that you need to reload the system again.

    Normally this wouldn't create any form of RAID Array using the CLI that way but depending on other installed software and depending on your hardware I wouldn't like to say defiantly one way or the other here. Basically if the Drive Capacity is correct for both Drives I would leave them alone till I was certain that I had a Backup of Everything unencrypted and readable on a different system. I wouldn't even trust a Backup done with any Backup Software I would want Plain Data Files that I could read with any system before I went any further.

    But as a check here if the system is performing read & Writes to the HDD faster you have a Stripped Array in action so attempting to format anything will prove detrimental to this install. That is if Windows will even let you do it.

    Using the CLI like this isn't recommended as with a Blank HDD there is no letter present so the Format Command can do anything most of which isn't good. You should always go into Drive Management to Format a newly added HDD.

    The weird, and so far unresolved problem is that it ws not a newly added hdd that I reformatted but an existing one so therefore no jumpers or cables were touched.
    Windows offers to let me add a parttion to the drive which I have hesitated to do as I'm not sure what would happen.

    Always go the the Drive Management Window to perform Formats. Doing this from the CLI isn't recommended as some strange things can and often do happen.

    I would still urge caution until you have a solid Known Good Backup in place and the means to reload the system if required.

    Disk management shows the two drives each with the correct letter i.e. C: Charlie and I: India but they seem to be contiguaous as the total of C: is in fact C: and I: added together.

    Do you have have 2 physical drives?

    or

    1 physical drive that has been partitioned into 2 logical drives? (this could explain why it appears that the 2 drives are combined)

    Have you tried loading the Windows XP repair to use the tools to check the disk? If not a suggest doing this and running the chkdisk, partition tool & format tools, etc.

    Secondly, make sure that they are correctly installed properly (master, slave, cabled correctly).

    Thanks for this suggestion but as the system can only "see" drive C: and cannot see drive I: its not been possible to run chkdsk on it.
    No cableing or jumpers have been changed all I did was to reformat the second physical drive.

    OK, you have 2 physical drives but the BIOS only shows 1 drive? Do you have a separate HDD controller card? And if I recall correctly, Disk Management shows 1 large drive?

    Simply formatting a drive from the command line isn't going to do what you describe. Unless the hard drive was going bad and it finally went during the format.

    For what it's worth, although there is nothing wrong with formatting a drive from the command line, I would recommend using Disk Management for this.

    Your first paragraph is correct and I can assure you all I did was on the command line input <Format I:> instead of using Disk Management.
    The reformatted drive isn't bad because when it is seen it does not report any errors.
