Symptom
When hard disk drives that are hot-added (i.e. inserted while Microsoft Windows is running) the user may get a prompt stating the drive is unformatted, even though the hard disk drive is formatted and contains valid data.

In certain cases on computers running File and Folder Encryption, hard disk drives that are hot-added (i.e. inserted while Windows is running) might not be properly recognized, and might appear to Windows as being unformatted.

Affected configurations
Any of the following IBM systems running Microsoft Windows 2000 or XP configured with IBM Client Security Software and File and Folder Encryption and the file system type on the c: drive is not the same as the file system on the hot-swapped hard disk drive:

• ThinkCentre (type 8185, 8187, 8188, 8189, 8183, 8184)
• ThinkPad (type 2660, 2662, 2647, 2652, 2653, 2656, 2654, 2658, 2659, 2677, 2681, 2683, 2682, 2672, 2373, 2366, 2367, 2648, 2673, 2722, 2723, 2724, 2884, 2885, 2890, 2891, 2374, 2375, 2376, 2379, 1829, 1830, 1831, 1832, 1833, 1836, 1840, 1841)
• NetVista (type 8181, 8182, 8301, 8303, 8304, 8305, 8306, 8307, 8308, 6290, 2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, 6348, 6644, 6645, 6646, 6843, 6844, 6842, 6881, 6837, 6847, 2251, 2271, 6830, 6831, 6840, 6841, 6058, 6059, 6568, 6569, 6578, 6579, 6599, 6647, 6648, 6649, 6650, 2255, 2275, 2273, 6043, 6790, 6791, 6792, 6793, 6794, 6795, 6822, 8309, 8310, 8311, 8312, 8313, 8314, 8315, 6280, 2283, 6274, 6596, 6838, 6848)

Workaround
Reboot the computer with the hard drive drive connected to the computer.

Solution
To allow for proper use of hot-added hard disk drives, ensure that the file system (i.e. FAT32 or NTFS) on drive C: and the partitions on your hot-added hard disk drive are the same.
