Windows 7: Partition Drives cannot be read

05 May 2011   #11

Windows 7 Ultimate x32

@lehnerus2000- maybe they can but i believe you guys knew a lot than them since all are 7-users.

@patio- thanks! i just did it.

@dsperber- thanks! the only problem came (in my 7 machine) after i reassigned the partitions' letters back to their original letters just to arrange the list. it took at least 4 to 5 minutes just to be read and scanned automatically by usb disk security. so the thing is maybe there's a way to refresh or revert back the settings of windows 7 in particular in assigning drive letters so should i format again the drive, it'll will automatically assign drive letters it has previously used.

another thing is, sometimes when i copy files to/from the external hdd, it says "cyclic redundancy check", cannot copy file. is there any software out there which can assist in copying files regardless of errors?

Run checkdisk on the drive - may fix the problem if you're lucky.


xcopy /c command


JFileRecovery - Recovers files from damaged hard drives, CDs, DVDs and Flash media.

Having nothing to do with any other aspects of this thread's topic, if you are getting what is essentially an "I/O error" writing to the drive, I'd be very very suspicious.

CRC technology is to guarantee that your do NOT have I/O errors, and hardware functionality actually can theoretically recover from bit loss.

So if you are getting essentially "unrecoverable I/O error" writing to the drive, I'd be very very suspcious.

My suggestion would be to do a low-level FORMAT, complete surface analysis, etc. Theoretically the hardware can take "bad sectors" out of service, assign spare sectors to transparently replace them, etc., at least normal internal hard drives (especially SCSI drives) can do that... as part of the low-level FORMAT function.

Are you sure this drive is reliable???

@dsperber- i've always reformat my external drives using NTFS system and under default allocation size. the drive is reliable since it is made by Toshiba. maybe the problem exists with this xp machine. nonetheless, thanks for the support and i really learn a lot from this forum.
