Sony Vaio Desktop - Recovery after harddisk failure



Sony Vaio Desktop - Recovery after harddisk failure
(hope this info helps someone out there)

Is this "delayed write" failure a Win XP problem or a Maxtor problem?

Sony Vaio Desktop model: PCV-RS720G
Win XP Home with SP2 (pre-installed by Sony)
System purchase date: 12/2004
Harddisk failure date: 7/2005
Harddisk: Maxtor DiamondMax Plus 9 200GB SATA/150 (3.5 Series)
HD Manufacture Date: 10/2004

I just encountered the notorious Win XP "Delayed Write" failure message.
It looked like XP was trying to write a registry entry when it croaked.
After a shutdown, the system would no longer boot.
Attempting to boot Win XP into Safe Mode caused the system to restart repeatedly (after it loaded System32\Drivers\Mup.sys)

Partition Magic 8 reported Critical Error 1601 (NTFS error) on the hidden 6GB partition created by Sony, and Critical Error 45
(checksum error) on the C: partition.
PM could not fix any of the partition errors.

Sony Tech Support (chat) told me to restore the system with my Vaio Recovery disks: 1 startup CD, and 1 DVD containing all the
software the Vaio ships out with.
But I didn't want to lose all my data on the HD just yet.

Sony Tech Support (toll-free number) said I could buy another HD, and try the Vaio Restore on the new HD, then try to copy the files
from the damaged HD installed as a secondary.
They would not officially support this technique.

Booting Caldera DR-DOS 7.3 (with the Read-Only NTFS Filesystem drivers) from a 3.5" floppy enabled me to read most of the C: drive,
and I was determined to get my data off the drive.
But the USB HDD drivers in DR-DOS would not recognize an external USB hard disk I had, so I couldn't copy the files off the damaged
hard disk :(

Booting with Symantec SystemWorks 2005's "Recovery Disk" CD enabled me to access my external USB hard disk, but it could not see the
files on the damaged hard disk :(

So I bought a Western Digital 300GB SATA HD ($139 (after $50 rebate), from Fry's), partitioned it into 6 + 280 , with the 280GB as
an active primary partition.

The Sony Vaio Recovery process went smoothly.
The hidden 6GB partition somehow became a hidden 5GB partition after the Vaio Restore.
But I'm glad the Sony Vaio Restore/Recovery process worked as advertised :)

When I booted Win XP off the new HD, Win XP was not able to read the damaged Maxtor harddisk.
Neither did Norton SystemWorks 2003's Disk Doctor :(
And PM 8 still reported a Critical Error 1601 on the hidden 5GB partition on the new HD :(
Is the Sony Recovery process causing the 1601 Critical Error in the partition area?

I didn't want to see another HD failure in 8 months when my HD fills up, so I decided to use PM to get rid of the hidden partition
and merge it with the NTFS partition.
I also created a 40GB FAT32 partition at the end of the WD HD so that I could write to it from DR-DOS.

I booted back into DR-DOS and painfully copied the files I wanted off the damaged Maxtor HD to the FAT32 partition on the new WD HD.
