"Error in IOCTL call" error message while formatting USB Drive


I recently got "ADATA USA DashDrive Choice UC510 USB 32GB Flash Drive (AUC510-32G-RTI)" from Amazon and tried formatting it to NTFS.

But this is what I get:

I tried it in command prompt as well:

C:\Users\Adrian>format e:
Insert new disk for drive E:
and press ENTER when ready...
Error in IOCTL call.


Open in new window

It looks to me that the drive is DoA. I'd prefer keeping it since I only paid $7. Any ideas would be great. Thanks.

the error is normally due to a fault with the drive, did you pull it out the USB socket while it was writing/or not using the Safely disconnect option and just pull the stick??

does it work in any other system as it is as FAT32?  If not, then $7 for 32GB stick is very very low, and i suspect it could be poor quality NAND chips.

I always recommend Kingston Data Traveller USB sticks, i have over 14 of them in different capacities and never had a failure in 6 years.....cheap sticks are cheap for a reason unfortunately, they don't last.

According to AData's FAQ, you need to type CONVERT E: /FS:NTFS in a CMD window.

if windows doesn't recognise the flash drive, doesn't matter what you try and do with the formatting.  i have formatted plenty to NTFS from the explorer interface, you only convert when you need to keep the data on the drive.

Thanks Iain and Davis.

No, it was the first time that I plugged the drive to the port. I tried to format to NTFS on another laptop and it seems to have worked.

I tried copying files (larger than 4GB) and it seems to be ok albeit a little slow (8 - 9 MB/s) over a 2.0 USB hub. The speed is fine by me.

I'm currently running CrystalDigitalMark tests on it and will post the results shortly.

Do these look ok to you guys? Seems they're pretty slow when plugged to an USB 2.0 hub. I don't have free ports to plug directly to. :(

depending on the NAND chips and how good your USB hub is, along with other factors such as AV scanning, OS overhead/transfer coding etc, that's about right, most good USB2 sticks peg out reading about 25-30MB/sec and writing about half of that, so getting 22/23 is about right and what you would expect to see.

Theoretical limit should be 60MB/sec, but your never going to get that unless you have a high end stick with dual memory controller and a perfect USB connection with no other factors/overheads in the way.
