2nd partition disappears in My Computer

[danfan1981]

I have two windows partitions: 1 NTFS (C and 1 FAT32 (E. After
running chkdsk on C drive to solve a bootup problem, E drive disappear
in My Computer.

But the 2nd partition is still shown as healthy in Computer Management

Disk Mangagement. When I right click on the 2nd partition, no options are allowed except to delete it.

How can I make E drive reappear in My Computer?

have you tried "fixpart" in recovery console ?

I think the first, and easiest step would be to go back into computer
management and right click the 2nd partition and choosing change drive
letter. Change the drive letter to E and see if it shows back up.

Sorry ignore my entry. I was half reading the posting.

There is no fixpart in recovery console, but there are diskpart,
fixmbr, fixboot.

I run diskpart and E: show up as
E: Partition2 (Inactive (OS/2 Boot Man19077 MB ( 2010 MB free)

There must be a trucation in the partition description. It is very
strange that E drive is recognized as OS/2 in diskpart, but it is
recognized as FAT32 in Disk Management. And in recovery console, I can
cd to E: and dir to show its content.

I have fixed it now. Knowing E drive shows up as an OS/2 drive makes me
think there is something wrong in the partition table.
I found the program SPFDISK on the web and look into the partition
table with it. The Sys_ID of my second partition is 1c which
corresponds to File_system [hidden]. So I change the Sys_ID to 0b which
corresponds to DOS FAT32. It is interesting to note that Sys_ID 0a
corresponds to OS/2 Boot Manag. So the Sys_ID were shifted somehow
after my initial booting problem and showed up with one or two byte
change in DISKPART and My Computer.

Glad it's resolved for you. Good work. Unfortunately chkdsk can have
unexpected results and since it keeps no really helpful log of what it
did, it's hard to recover. Think about using a disk imaging program
such as Symantec's Ghost, Acronis True Image, Terabyte Unlimited's Image
for Windows or BootIt NG to keep an image of the partitions on a
removable drive and/or DVD. Then if a problem like this occurs you can
readily recover.
