I have a 2 gb usb drive and it has a corrupted boot sector so i cant save data and also cant format it . I tried to format it using various data erasers (kill disk , driverestore professional , . . etc) but i couldnt . i want to know how can i fix corrupted boot sector ???

It should be the file system problem. Usually a usb drive should be formatted to FAT initially instead of NTFS. Recommend you try the USB on another computer and see if the problem still occurs. If yes, then try format it from Disk Management of your computer. If you can't format, use TestDisk (also a command line tool) to fix the file system error. You can also see from this blog post to learn more about the possible reasons or solution. Regards

Files on a flash drive canbe corrupted if it is not removed from the USB port properly.

Many times the pen drive can not be formatted or is not detected. If these problems occur and according to what you describe,The pen drive you are using has corrupted memory sectors. Its of no good use, if under warranty, go for a exchange from the service support or else Buy a new pen drive.

try to connect your device into your pc and then, try to save files again, if this doesnt work, try to reformat your hard drive, im sorry to say that all your previous files will be deleted upon the format. after this, make partitions to hard drive. then save some of your files into it. if that doesn't work either, try a disk scan to check if your hard drive has bad sectors.

Possible Reasons:
1. Your USB flash is too old and can be corrupted with time went on. As you know no hardware can be life-long ever.
2. There are bad sectors in the specific area of the disk that is required for a file system, e.g. for a boot sector or the FAT table sector. Since such a drive is obviously not possible to use, Windows refuses to format it.
3. Sometimes, you cannot format the drive to the FAT file system if it has been formatted to a file system which is not recognized by Windows. Such a drive should be reformatted to NTFS first, and then to the FAT file system.

Solution:
Step 1: Try the problem USB on another computer (better be most common Windows OS). See if the device can be accessed normally. This way can clear the buffers and eliminate incompatibility. Sometimes it will let the error disappear and make the drive work normally again.
Step 2: If the first method still won't help. Try recovering the data with some data recovery programs first of all. If you are running Windows, you can use Data Recovery for Windows. For Mac OS X users, turn to Data Recovery for Mac
Step 3: After the files are recovered, then follow those steps to try format the error USB drive (connect the disk to your PC first). My computer -> Properties -> Manage -> Computer Management -> Storage -> Disk Management -> select the problem drive and then format it from here.
Step 4: It's not over. After formatting, try use the data recovery software recommended in #2 to re-scan the drive to see if you can harvest more data. Good luck!

Re: A Disk Read Error Occured. Press CTRL ALT DEL to restart

1 - Have you tried a different IDE cable?
If not give it a go and do a repair if needed again!

2 - You may have a corrupt MBR (master boot record)!! You will need to reformat and do Fdisk /mbr to delete the master boot record!! Save all data first as this will not allow you to access any of your data as all file location addresses are located in the MBR!!

3 - Your harddrive may have a bad sector get a zerofill tool(low level formatting tool)!! This will rewrite you HD's sectors putting them back to factory spec's!! Maxtors is called Maxblast you can get it from thier site!!

4 - or it could be a defective drive, but most read errors are due ot corrupt MBR or a bad sector!! Good Luck D.i.l.i.p
