Which function can I use in VC6? Prompt : there are not the CHS parameters for USB flash disk .

I want to get the disk size for every physical disk. The CHS parameter is true for harddisk,but wrong for USB flash disk. Becase the system assume that's X*255*63,the total sectors are also wrong. I dont know what function can I use.

The USB flash disk have no CHS parameters (the system use virtual parameters),I only need to get teh total sectors for physical drive. The MBR and BOOT may be failure. so your function is invalid. ,how to do it? Thanks.

There are 2 main structures in Windows system: FAT32 & NTFS. The NTFS system is similar to the UNIX ,But the FAT32 are not. you can search the topic about FAT32 from MSDN or Google.:laugh:

The CFloppyDisk use the folling sentence to read the sector,so it cannot pass the error.:(:( CreateFile("\\\\.\\A:", GENERIC_READ|GENERIC_WRITE,0, NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

I want to recovery the floppy disk,but cannot read the sectors when the 0 sector is bad. The tool HD copy and DiskEdit can do it. How to do it? My program is running in MFC mode but not console mode
