System Basics: Windows XP Professional w/SP3 and all patches Acronis True Image v18.104.22.16853 Boot disk C: 250Gb internal Seagate SATA (5 months old); just one partition Backup disk D: internal WD 250 Gb P-IDE (1 month old); just one partition 1 Gb DDR PC3200 RAM AMD Athlon XP 3200 "Acronis Backup Location:" D:\Backups\Acronis\ New Acronis patched "scheduler2" files Disabled TrkWks Service The Issue: I have schedules nightly incremental backups to my internal D drive, using these Backup Location parameters: 60 Gb limit 6 Backups maximum 365 days limit Most of the time the backups start and finish properly. I have them validated also. Lately I find that a backup will initiate then quit, with errors. When I read the Acronis log I see the same error: Partition Error. Some of the selected partitions have the following error: MFT bitmap corrupted. module="7" Operation with partition "0-0" was terminated. Details: MFT bitmap corrupted (0x7001 Tag = 0x89D94B01B483E13C Normally I would suspect that my new D drive must have crosslinked files, or a corrupted FAT, so I reboot and run Chkdsk /p, or /r. After returning to Windows the backups run normally once or twice, then the MFT Bitmap errors return. Today I tried something different. First, I ran the backup task manually and it failed with the MFT error. I spent about 20 minutes searching this forum for similar reports, closed three running applications (MailWasher Pro, Trillian, Windows Live Mail), then opened the Acronis interface and ran the task again. This time it completed the backup and validation just fine! What gives? How can the Master Filing Table be corrupt one minute and readable a few minutes later, with no further disk maintenance? Through all of the Acronis failures to record a backup, Windows Backups have been going on every night, virtually flawlessly. I say virtually, because for the last few nights they have failed to start due to the fact that the "Remote Storage Service" was not running! That service is set to Automatic and Started, upon bootup. It never stops running until the failed Acronis backup attempts, which take out that service! In an effort to stop Acronis from killing off the Remote Storage Service I have disabled the TrkWks Service, which was suggested in another post on this forum. We'll see if that solves the problem with the service. Your input is requested!
