chs values
Posted: 21 Nov 2016, 10:50
Hi guys, I recently had 3 drives all loose their data while putting computer into sleep mode (or coming out). I suspected the disk controller and bought a new PC.
However I can only access the disk via a USB port and they look unformatted to windows (I think).
I have had some extremely long scans of the main disk I need to recover with various errors. After the first scan, I managed to access the partition if found but their were just 2 directories and no files.
This time I put in the manufacturers (Seagate) CHS values and it is still scanning after 14 hours with large numbers of suspected partitions and mismatch errors.
I would like to know just how important are these CHS values as I've read somewhere they are arbitrary to how the computer accesses the disk? Or is this all about finding the correct values? Just to make it more difficult, the values I found at Seagate covered 4 hard drive models and 2 were 80gb and 2 were 160gb, which really doesn't make sense???
Any help appreciated.
I would just like to add that I had difficulty getting the BIOS to recognise these disks and went and bought a USB lead with a PATA connector. The error in Windows 7
was that the disk was "corrupt and unusable" and could not run chkdsk.
