vishalmcp 8 Report post Posted June 9, 2008 Hi all, I am having a usb pen drive, its printed "sony" on it. But the chipset its showing is "Alcor". the capacity its showing is 120 Gb. But without any data in it when i saw the space usage its showing 4 gb used. With windows XP proff. I am not able to even format it. When I copy some data in it it gets copied properly but after some time again when we re-insert it, the folder size becomes 0 kb with no data in it. I have tried with different pc's but still the same. I think its a fake one, with some sort of memory hack done so it is showing more capacity then it might be having. I have searched on net but i am not able to find any proper solution to it. So if anyone has any tool through which I can format it & get the usable actual capacity of it, please do tell me. Would be waiting for answers. 2 Share this post Link to post Share on other sites

Some of these fake Chinese pen-drives bear brand names like Sony, Toshiba and will show very high capacity but will not work for even a fraction of the claim. This is a lost case, my friend. Consider it as a wastage of money. And don't waste time over it. Share this post Link to post Share on other sites
ashoksoft 83 Report post Posted June 9, 2008 It normally is caused by a defective zero sector / FAT info. An ideal solution would be to use a low level formatter for the USB drive, (you can try HP Key format), and then format with the normal windows format tool.. cheers karki Share this post Link to post Share on other sites
kshah 452 Report post Posted June 10, 2008 It is not defective zero sector, in many cases it is hacked zero sector. Year and a half back, I bought 1GB MP4 player from China. It can copy all 1 GB but can not read beyong 256 MB, I searched net and found that they hack zero / fat info and make it the capacity they want. I posted it some where here too.

Honest 836 Report post Posted June 10, 2008 I too used to double the space of my harddisk with the same disk compression utility known as DOUBLE SPACE / DRIVE SPACE in 1994. When I have 256 MB Hard Disk Drive and works on Windows 3.0 / 3.1 @ashok My dear friend, your post remembered me of my old days. Regards. Share this post Link to post Share on other sites

That's the reason that now people selling MP3/4 players explictly claim that 1 GB means full 1 GB usable as can be seen in most eBay listings. Otherwise there is no need for such claims.
