I haven't needed to use recovery programs recently, but you could search these forums for "recovery", some freebies have been suggested.
If this is the "same" problem that occurred previously, I might think there was a problem in the boot sector (MBR) of the drive. After you recovered your data, I would look at completely removing the partitions and even doing a low-level (zero) format if that was possible. Run through Maxtor's utilities for the drive. If a utility "EZ Bios
" is offered, do not
install it (although if you run out of options to recover your data, try installing it, recover the data, then uninstall it).
If you are using NTFS
format, see what Maxtor recommend, but I would use FAT32. NTFS
is more important on the Windows drive.
