Chinese magical harddrive

He works at a hard-drive repair center in a Russian town, located near the Chinese border. A couple of days ago a customer has brought a broken 500Gb USB-drive that he had bought in a Chinese store across the river, for an insanely low price. But the drive was not working: if you, say, save a movie onto the drive, playing the saved movie back resulted in replaying just the last 5 minutes of the film.

There were some incident like this over the TPC forums a few months/years ago regarding a 16GB-128GB flashdrives but can only store upto 2GB of files in it, once you store more than 2GB of files, everything gets corrupted.

One of my CDRKing bought "Kingston" 2GB flash drive was something similar.

OS reads and formats it as 2GB but, it can only store ~600MB of data.

doh!  FAT32 file size limit fail. :P

Wanted to demonstrate something else, this drive's been reformatted a few times as it wouldn't write files beyond the 4GB mark.

EDIT.
come on Toshi!

Like this?


You need to format it to a filesystem which can handle more than (2GB-1Byte) file, like NTFS, my question is, can you fill up the flash drive with 8GB of files with less than 2GB filesize?

Had about <2GB of stuff here, mostly MP3's and video files at one point then it wouldn't take anymore.

Standby, reformatting, damn thing is taking forever, and quick format is not an option.

Correction -its stuck.

As one commented on slashdot pointed out, this isn't exactly an uncommon scenario:


Something between two nuts turns out smaller than advertised. =P

something like that... once it reaches ~600 MB.
no matter what file type or size I transfer

Tried it with EXFAT:


Suddenly it has a lock feature.

Damn thing will only allow "quick formatting" for FAT32 and EXFAT and nothing else.  Unfortunately it costs me more in terms of time to make a claim with CDR-King.

Been trying to write more than 2GB of files on this thing.  No go.

I've been noticing a surge of foreign shops selling ultra cheap 1 to 2-TB HDD and USB flash drives on Shopee.I wouldn't be surprised if the 5-star ratings are all rigged as well.
One thing I noticed in the product description is this statement:

"Default Formatting is ExFAT and NTFS is not allowed!"
How exactly does ExFAT allow them to cheat the drive size?

ExFAT (or FAT)  - uses a (F)ile (A)llocation (T)able, that reside on the first few sectors of the disk, it provides a "map" of the whole disk, where as NTFS, which has an MFT (Master File Table) which is like a linked list that reside throughout the whole disk.

The thing is, using ExFAT, all file-entries and table reside in the first few megabyte of the disk, and the data is below it, so you will always see a listing of your files even if half  of the drive is gone (corrupted), thus you won't notice that your files are corrupted since the files are there... (will take a long time before you realize that your files are gone)

whereas with NTFS, the file structure is scattered on the disk, so if the data for the file-entries are gone (written on the non-existent part of the disk), then you won't see the files, you will notice the corruption right away.

^So that's how they do it.

I pity those who fall for those scams. Some probably take one look at Windows explorer, see the "correct" capacity and give the scammers an OK rating. I still hope the drives are still usable even if they wind up having a smaller capacity.
