I'm recently having very weird hard drive/usb drive/power/? problem. I noticed this problem when I was copying some files from HDD to USB. I noticed that file transfer rate gradually decreased and file transfer stopped between files (USB drive used NTFS file system and the problem persists in all NTFS usb storage devices, FAT32 one are slow but fine, i guess). And then I noticed that file transfer rates gradually decreased in HDD also (I use one 1.5 tb SATA 2 HDD and one 300 gb SATA hdd). I formatted one partition of my sata 2 HDD, reinstalled Windows with a fress install and unplugged the sata 1 hdd and the problem persists. As of right now my transfer rates:
SATA 2 Drive:
Copying 7 gb file from one Partition to Same Partition:
Starts off at 150 mb/s, gradually decreases to 33,34 mb/s.
Copying 7 gb file From one partition to another partition:
Starts off at 120 mb/s, gradually decreases to 30,31 mb/s.
SATA 1 Drive:
Copying 7 gb file from one Partition to Same Partition:
Starts off at 100 mb/s, gradually decreases to 14,4 mb/s.
Copying 7 gb file from SATA 2 to SATA 1 Drive:
Starts off at 150 mb/s, gradually decreases to 45,8 mb/s (i tried it again and it decreased to 34,4 mb/s).
Copying 7 gb file from SATA 1 to SATA 2 Drive:
starts off at 40 mb/s, gradually decreases to 24,5 mb/s.
I tried HD tune pro and some errors came up:
1.5 TB SATA 2 HDD:
Reallocated Sector Count: Data:23
Spin Retry Count: Data: 2
300 GB SATA (1) HDD:
Current Pending Sector: Data: 4
Ultra DMA CRC Error Count: 1
I tried switching AHCI and IDE modes back and forth (reinstalling OS everytime) without any difference in performance.
USB to any HDD transfer is fine with about 34 mb/s.
By the way, my computer switched itself off while watching a movie one time recently (like a PSU error). Maybe this happened after it? I don't know.
Computer is virus free but it is irrelevant as i installed another OS. But it is virus free as i checked with various antivirus scanners.
What the hell is going on?
