Storages are not always present in XML

Hello OCS team,

I meet an issue on OCS Inventory Client version 2.1.1.1.

Storages are not always present in XML, only Floppy and CDROM are present but no harddrives.

Information about server:
- OS: Windows Server 2008 SP2 Ent 32 bit
- Language: Chinese (TW)

- The hard drive WMI class seems to be OK.
- The 2.1.1.2 version is not compatible with 32 bits OS and cannot be tested.
- on sysinfo log, disk are not found.

I reinstall OCS and it seems to work at first execution:

ocs.log:
INVENTORY => 5 storage peripheral(s) found

sysinfo.log:
<Manufacturer: (Standard disk drives)><Caption: VMware Virtual disk SCSI Disk Device><Description: Disk drive><Name: //./PHYSICALDRIVE0><MediaType: Fixed hard disk media><Size: 102398><S/N: ><FirmwareRevision: 1.0>
        <Manufacturer: (Standard disk drives)><Caption: VMware Virtual disk SCSI Disk Device><Description: Disk drive><Name: //./PHYSICALDRIVE1><MediaType: Fixed hard disk media><Size: 460794><S/N: ><FirmwareRevision: 1.0>
        <Manufacturer: (Standard disk drives)><Caption: VMware Virtual disk SCSI Disk Device><Description: Disk drive><Name: //./PHYSICALDRIVE2><MediaType: Fixed hard disk media><Size: 272202><S/N: ><FirmwareRevision: 1.0>

But when I run again, it random fails. HardDrives are not present again
Please tell me if any file or info is missing in my ticket to help fix this problem with you.

Thanks & Regards,

Pierre
