Storport Miniport Driver for 4K Blk Sz PCIe SSD Device Development

Question

Hi,

I am writing a storport miniport driver for our 4K blk sz PCIe 8GB SSD device to run at Win 7 (64-bit) environment. When I created a volume less than 4GB, the device can be formatted to FAT successfully (without obvious issue). Read and write files to it appears without any issue.

However, at any volume size (8GB, 4GB or 1GB), whenever I try it with FAT32 or NTFS, it will failed with "The format did not complete successfully".  If it is a "Quick" format", it fails pretty quick.  If it's a "Full" format, it fails towards the end, appears when (or after) trying to write the structure.

Any idea what could cause this failure?  What am I missing? 

Could there be any Config parameter, SCSI mode page or Inquiry data requirement missing?

 

Please advise.  Many thanks in advance!!

Answer 1

Can you format a 4GB or smaller disk to NTFS? That is, are there any success cases for NTFS or FAT32?

Answer 2

Hi JA,

No, cannot.  No success case for FAT32 and NTFS at all so far.

I have tried 4095MB and 1024MB.  Only FAT works, both FAT32 and NTFS fail.
