Please help with my USB flash drive.

usb flash drive insert disk

Hello all,

I have recently purchased a transcend jetflash 130 4GB flash memory. It was OK last night when I filled it with data and copied all to my computer. but today I cannot use it at all. My computer detects it when it is connected to the computer and I can remove it easily from the safe remove part in the start menu toolbar.
But when I try to access it from My Computer it says: "Please insert a disk into drive H:" and when I try to format it it says: "There is no disk in drive H:. Insert a disk and then try again". Then I tried to format it by DOS. using "format H:" but is says : "Insert new disk for drive H:"!!!! I even tried to use "Data Doctor Recovery Pen drive" to recover it and still, there was no luck!!
What should I do now? do you think there's something wrong with the hardware itself? or maybe it's file system has been corrupted somehow. do you guys have any softwares for accessing the flash memory low-level?

Regards,

Dear, I am also trying to fix my USB stick since morning but all the efforts seem to be ending in smoke. I tried so many software. Initially it was being detected but on double clicking a message for format was displayed but the format was always successful. I tried to fix through Management option of My Computer and suddenly it seemed to be ok to some extend because instead of 4 gb I could only have 2 GB and the rest 2GB always appeared to be used space. I formated so many times but it could not be fixed. they I tried some other software and the disk went down completely.

I tried HP USB DISK STORAGE FORMAT TOOL V 2.1.8 but it displayed an error "device media is write protected" but I never did it write protected.
then I tried a low level format utility PTDD Partition Table Doctor 3.5 Demo. initially it displayed some error but then completed the format and displayed a message something like " The format is complete now create the partition and format" I could find no option in this software to create a partition.

this is the current position.
Please let me know did you fixed your problem.

I am attaching the low lever format file. Please try it and let me know did it worked for you

flash memory please insert a disk into drive

Dear friend,

I had my Flash tested a few days later and it was a hardware issue. They gave me a new one and it's working fine. It is the hardware inside.
