This is a brand new hard drive. i plugged it into my toshiba satellite a300 laptop and ran the setup and all was fine. then i copied about 1 GB worth of files to the hard drive. but then i decided to delete them but they wouldnt show up in my explorer not even as system files or hidden files so i decided to format the hard drive. i started the format but the power supply was cut in the middle of the formatting process. when power supply was back, I tried to access the hadr drive but windows keep telling me to format the drive. so i click ok but windows again says that it cannot format it. in the properties it shows 0 bytes and file system is raw! Please help me to get the HDD working !
Hi manar_94,
It probably is not a faulty drive, although it might be. To check download and run HDTune v2.55 (freeware) Error Scan. Select this disk. It will take about 6hrs on USB 2. if nothing is wrong. It will show if the disk has bad sectors. (the program's 'block size' has nothing to do with disk sectors or allocations. A damaged block simply indicates that one or more smaller sectors within that 'block' are damaged. A few damaged blocks doesn't mean that your drive is unusable, though it might be cause to RMA the drive to Seagate for a replacement. Ensure that the disk in no way becomes disconnected from the PC during this test, else you will see bad blocks form that point on and the test will finish more quickly)
I do not know about recovering files from a RAW disk. You should always keep a back up of your files anyway.
I have read that a way of formatting the disk is to re-partition the disk and then format it. I have this problem as well, after my external disk somehow lost communication with my PC, showed in USB system and MyComputer, but not in diskManagement, until I disconnected & reconnected the USB plug, then it showec in DiskManagemennt but wouldn't format from there (Windows message "format failed to complete to complete successfully" instantly appeared). Try going to DiskManagement, right click on the long area of the RAW saegate disk (careful to ensure you have select the correct disk), and choose create new partition option I think it will be, maybe it's erase partition. after that you may have to re-initialize the disk, and then format it to NTFS. The instructions I read said you need to do these from the command line (CMD tool), using diskpart to delete the old partition on the disk, and the FORMAT command to format the disk. You will need. I suspect, to look up (on your PC -> search tool) how to do this in detail. It might take an afternoon or a few hours.
You might also try searching the internet as to how to solve this, or/and contacting Seagate support - the latter is probably best)
I hope you solve the problem.

Hello, also have got a RAW file system problem with your Seagate external hard disk? Honestly, last time, when my external hard disk showed RAW file system and asked me to format, I did have tried two steps to restore both of my left drive files and this USB hard disk.
Firstly, stop using this drive and go recover lost RAW format portable hard disk data with RAW drive data recovery software.
And then, format this drive to convert it from RAW to NTFS and also restore its common use after backing all rescued drive data well.
Therefore, hope you can also learn something useful to cope with your RAW format memory card issues.
It's probably a bad drive.
